[users@httpd] PHP-CGI with Apache-2.4.37

[Hemant Chaudhary]

Hi All,

I want to use my php scripts using mod-cgi.

httpd.conf
AddHandler application/x-httpd-php7 php
 AddHandler application/x-httpd-php7 .php

and my first.php is like

#!/usr/bin/php-cgi



But when I am sending request from browser, my php page got displayed
there instead of content of php page.

Permission of php file is -rwxr-xr-x

Please let me know what am I missing ?


Thanks

[users@httpd] ThreadsPerChild in apache-2.4.37

[Hemant Chaudhary]

Hi All,

1) I am using apache-2.4.37 and found that when I am setting
ThreadsPerChild to 5 or 10, it is not creating that number of threads.
Still it creates default threads i:e 25 in debug mode (-X) option.
Whether this parameter doesn't work in debug mode or any issue in
apache-2.4.37 ?

2) I am not able to handle SIGTERM signal in apache server when using
worker module whereas it is possible in prefork module when starting in
debug mode (-X).
While going thorough the code, I came across this snippet :

/* !one_process */
/* remove SIGTERM from the set of blocked signals...  if one of
 * the other threads in the process needs to take us down
 * (e.g., for MaxConnectionsPerChild) it will send us SIGTERM
 */
unblock_signal(SIGTERM);
apr_signal(SIGTERM, dummy_signal_handler);

Whereas unblock_signal is missing in debug mode i:e one process mode.

Whether this is the reason that we are not able to handle sigterm in worker
because it is blocked ?

Thanks
Hemant

Hi,,
3) I am using mod_proxy and mod_proxy_http to proxy request to backend
server.
With http we have stream flow of message.

[users@httpd] Doubts in apache-2.4.37

[Hemant Chaudhary]

Hi Team,

I have following doubt, please help me to understand

1) I am using worker MPM and according to architecture, each child process
creates one worker listener thread which has mutex and listens on the port.
If I am using two ports 80 and 443 then whether each child creates two
listener thread  to listen on each port(80 and 443) or it will create only
one listener thread.

2) When mod_cgi forks the another process and sends the response back to
client then the communication between http process and forked process
happens through pipe or socket.

3) When we proxy https request to backend server like tomcat then whether
message transfers takes place in stream manner or it sends the whole
message to backend server after decrypt the message.

Please let me know if I am not clear.

Thanks

Re: [users@httpd] Graceful shutdown of apache

[Hemant Chaudhary]

How can I stop process running with -X option.

Terminate signal (kill -term pid) is not working here(worker mpm) wherase
terminate signal works if -X option is used with prefork mpm.

I am able to stop only by kill -9 signal.

Thanks

In -X mode you don't have a parent -> children relationship with httpd,
just the worker process. It isn't for normal operation.

Hi,

I am not able to shutdown apache gracefully if I am starting apache in
debug mode i:e (./httpd -X) with worker mpm. I am sending kill -term PID to
httpd process. wherease the same command is working with prefork.

How should I stop worker mpm if started in debug mode ?

[users@httpd] Cleanup in apache

[Hemant Chaudhary]

Hi All,

I am using apache-2.4.25 and apr-1.5.2.
When I am using mod_autoindex for indexing of icons directory, after
serving the request the process gets crashed.

I debugged and checked that it was getting crashed
from apr_pool_cleanup_kill ().
The line which causes the crash is "c->data == data && c->plain_cleanup_fn
== cleanup_f".

Please help me out the reason or this crash. Does anybody had this issue
before?

Thanks

[users@httpd] Issue while listing Directory using mod_autoindex

[Hemant Chaudhary]

Hi All,

When I am trying to list directory in apache. My process get killed and I
was not able to see directory. During debugging I have seen that
"apr_dir_close(thedir);" apr_dir_close in function index_directory is
killing my process. So I have commented this function from index_directory.

After commenting, I am able to see the listing of directory but after
listing my directory process is getting killed again. While debugging got
the following stack trace:

->in run_cleanups () in /usr/local/lib/libapr-1.so
 -> in apr_pool_destroy () in /usr/local/lib/libapr-1.so
-> in eor_bucket_destroy at
\home\apache29\apache-2.4.29\httpd-2.4.29\server\eor_bucket.c:90
->in remove_empty_buckets at
\home\apache29\apache-2.4.29\httpd-2.4.29\server\core_filters.c:733
 ->send_brigade_nonblocking

I have few questions on this:
1) What is the significance of apr_dir_close(thedir); ?? If I will comment
this out then what will happen ?
2) What may be the cause for my process is getting killed before and after
comment.

Please help to solve this issue.

Re: [users@httpd] Get request of large file size greater than 100KB

I have solved the problem by changing MAX_IOVEC_TO_WRITE value to 6 from

[users@httpd] Get request of large file size greater than 100KB

[Hemant Chaudhary]

Hi All,

I am trying to access large file(get request) of large file. This is
working properly if size of file is less than 52KB. But size greater than
52KB is giving me error 4022.

I have debugged and come to know that writev function can write maximum
upto 52KB only. Therefore I changed the default value of
THRESOLD_MAX_BUFFER to 42KB so that my writev will not reach to 52KB.
THRESOLD_MAX_BUFFER to 42KB helps me to solve the issue for PUT request.

But in get request while accessing large file, size of brigade crosses
52KB. As 52KB is greater than THRESOLD_MAX_BUFFER(42KB). It is trying to
flush the data. But limit of writev on my OS is maximum 52KB only.
Therefore it is giving 4022 error.

Is there any way where I can control apache so that size of brigade will
never cross 52KB? or any other approach/ configuration parameter can be
used to solve this issue ?

Thanks
Hemant

Re: [users@httpd] Re: Non Blocking write in apache

[Hemant Chaudhary]

Hi All,

I have a limitation for writev and readv to 52KB.
I was getting error for writev, therefore I changed THRESHOLD_MAX_BUFFER to
42KB. After that I was not getting any error.
Now in GET request of large file, I am getting the same 4022 error. This
may be because of readv function.

Is there any buffer/place where I can restrict readv to 42KB only,so that
it will not cross 52KB.

Thanks
Hemant

Hi Yann,

42Kb works for me. Thanks for your support.

Re: [users@httpd] Re: Non Blocking write in apache

[Hemant Chaudhary]

If it will flush data then at what condition it will go to apr_poll
function ??

What I understand is that if buffer is filled with 52KB data and writev is
not ready then it should go into apr_poll().


Now the problem may exist with 42KB also.

I hope I am explained my issue.

Thanks
Hemant

Re: [users@httpd] Re: Non Blocking write in apache

[Hemant Chaudhary]

Hi,

in the apache error_log with trace6, it is trying to flush because it
reached thresold_max_buffer. But at the same time, it is adding data in
buffer which increases it size to to more than 52KB and fails on NonStop.
How should I stop apache so that it should go to select function till 52KB
success.

Attaching error_log with new change.

Thanks
Hemant

Re: [users@httpd] Re: Non Blocking write in apache

[Hemant Chaudhary]

Hi Yann,

Thanks for your explanation. I got  the issue.
Actually NonStop has maximum limit of 52KB only for writev. Therefore I was
getting 4022 after 49KB. Because after 49KB, apache is adding 8K more bytes
which leads to 56KB. Therefore, writev was failing.

To solve this, I have changed  THRESHOLD_MAX_BUFFER in core_filter.c to
5. But again I am seeing that after 49KB, apache is adding 8192 Bytes
in it, which leads to failure of writev again.

Do I need to change in more places or the above fix should work.
Thanks
Hemant

Re: [users@httpd] Re: Non Blocking write in apache

[Hemant Chaudhary]

Hi Yann,
Please don't get confuse with Cygwin(Windows). I am running apache on
NonStop(Tandem). I have put breakpoint at apr_poll() but it is not going
there.

Few Events of writing :
1) apache writes 779 bytes to tomcat from apr_socket_sendv() function and
writev functions returns success.
2) apache writes 24604 bytes to tomcat from apr_socket_sendv() function but
writev function returns -1 with EWOULDBLOCK and it has timeout=0(because
set in writev_nonblocking())
3) apache again tries to write 32796 to tomcat from apr_socket_sendv()
function but writev function returns -1 with EWOULDBLOCK and it has
timeout=0(because set in writev_nonblocking()).
4) apache again tries to write 40988 to tomcat from apr_socket_sendv()
function but writev function returns -1 with EWOULDBLOCK and it has
timeout=0(because set in writev_nonblocking()).
5) apache again tries to write 49180 to tomcat from apr_socket_sendv()
function but writev function returns -1 with EWOULDBLOCK and it has
timeout=0(because set in writev_nonblocking()).
6) After this I am getting 4022 error.

What is happening here that after 24604 bytes in step 2, apache is 8192
bytes in buffer till step 5 and then giving 4022 error.
All timeouts has default value.

I am wondering that why is it not going into select() if writev is
returning -1 with EWOULDBLOCK.
Why is it  failing after 49180 bytes. Does max size for this buffer is 49K??

I am able to upload same file if I am using blocking call.
Please let me know if you need more information.

Thanks
Hemant

Hi Yann

I have tried to upload a file of 26.5mb on apache tomcat, which was
successfull.
I tried to proxy request to tomcat with same file. But get following error.
Attaching the error_log.

Can you please help me to understand where I am going wrong ?

[users@httpd] Re: Non Blocking write in apache

[Hemant Chaudhary]

Hi All,

Actually it is setting sock->timeout to 0 in writev_nonblocking() in
core_filters.c.
arv = apr_socket_timeout_set(s, 0);

Why does the default timeout  is changed and set to 0 ??
Thanks
Hemant

[users@httpd] Non Blocking write in apache

[Hemant Chaudhary]

Hi All,

I am using proxy_http to proxy my request to tomcat from apache. But in
non-blocking call it is not working properly(timeout issue). I am using the
default timeout i:e 60 sec.

When writev returns -1 with errorno==4101, it should wait and then again
try for write.
while ((rv == -1) && (errno == EAGAIN || errno == EWOULDBLOCK)
  && (sock->timeout > 0)) _ code snippet from
sendrecv.c

In debugging I have checked that sock->timeout is equal to 0. Therefore
this condition is failed and request failed.

When default timeout is 60sec then why does sock->timeout becomes 0 ??

On further debugging, I came to know the reqtimeout_eor function is setting
timeout to 0.

static apr_status_t reqtimeout_eor(ap_filter_t *f, apr_bucket_brigade *bb)
{
if (!APR_BRIGADE_EMPTY(bb) && AP_BUCKET_IS_EOR(APR_BRIGADE_LAST(bb))) {
reqtimeout_con_cfg *ccfg = f->ctx;
ccfg->timeout_at = 0;
}
return ap_pass_brigade(f->next, bb);
}

I am not able to understand why this function is setting to 0.

Can somebody help me to understand the issue ?

Thanks

[users@httpd] Message buffer in Apache Web Server

[Hemant Chaudhary]

Hi All,

I want to send 1MB of data of request at a time. For this I want to use
buffer in proxy_http. By default we can send 8192(8kb) of data at a time.

I have used ProxyIOBufferSize and BufferSize, but still it is sending 8192
only.

I tried to set these value to 512, so that it will send 512 Bytes at a
time. But again it is sending more than 512 Bytes.

How should I configure so that it can buffer the message till reaches the
buffer size or request is complete.

Thanks

[users@httpd] Buffer in apache

[Hemant Chaudhary]

Hi All,

I want to use buffer of 512B in apache . I am using mod_proxy_http to send
request to tomcat and have set  ProxyIOBufferSize 512.

But it is sending message to tomcat with size greater than 512B.

How should I control apache in proxy so that it will send message and
receive with max buffer size of 512B.

Re: [users@httpd] PHP-7.2.5 with Apache-2.4.25

[Hemant Chaudhary]

Hi Frank,

When we start server which has mod_php then during it first dry run, it
loads the module and deload the module. After successful completion of
first dry run, it reads the configuration file second time and starts the
apache server.
During first dry run, dlopen() function loads the php module properly but
while deloading it using dlclose() it is throwing error. This means that
mod_php is not able to unload properly.

[users@httpd] Scoreboard file

[Hemant Chaudhary]

Hi,

According to Apache documentation, parent and Child processes communicate
with shared memory. But I don't have shared memory, therefore they are
communicating through scoreboard file.

I added " ScoreBoardFile /apache/logs/apache_runtime_status " in httpd.conf
to create file at this location. When I started, apache_runtime_status file
get created at above location. But this file contains only 4 Bytes and
file is not getting updated with load on apache. Then how child and parent
processes are communicating with this 4 Byte scoreboard file?  Is there any
other file or way to communicate b/w child and parent process other than
shared memory or scoreboard file ?

[users@httpd] Apache 2.0 architecture

[Hemant Chaudhary]

Hi All,

While Debugging apache, I encountered with following questions. I am unable
to get answers for the following questions, please help to answer them.

Q1. Startup process is reading configuration two times and creating
conftree. Why do we need to read configuration script twice? Is there any
difference in conftree after first and second read of configuration script.

Q2.  When we start apache, it starts with startup process and then it
detaches and starts Master/Parent Process. After that Master Process take
control and spawn child processes. Why do we need to detach startup process
and start Master Process ?

Q3. If I will start my server in debug mode i:e with -X option then what of
the apache functionality will I loose other than child spawn ?

[users@httpd] Integrate Apache-2.4.25 with tomcat-8.5.23

[Hemant Chaudhary]

Hi,

My apache is running on 15.213.91.33:5643 at location "/home/hemant/apache"
and tomcat-8.5.x is running on 15.213.91.33:8009 at location
/home/hemant/tomcat.

To integrate apache with tomcat I used mod_proxy and mod_proxy_ajp.
My httpd.conf looks like this :

ProxyPass "ajp://15.213.91.33:8009"
ProxyPassReverse "ajp://15.213.91.33:8009"


My server.xml is configured like :


When I am accessing "15.213.91.33:5643/ajp" then index.html of tomcat
appears, but If I click on any tab on page  then error 404 occurs because
URL changes to "15.213.91.33:5643/doc" (If I click on doc tab on
index.html). I think to work url should change to "15.213.91.33:5643/ajp/doc
".

Please let me know where my configuration is wrong ?

Re: [users@httpd] Worker MPM with debug mode

[users@httpd] Worker MPM with debug mode

[Hemant Chaudhary]

Hi All ,

I added the following patch of code in my worker.c
static void clean_child_exit(int code)

 if (one_process) {
 prefork_note_child_killed(/* slot */ 0, 0, 0);
+atexit(apr_terminate);
 }
 ap_mpm_pod_close(my_bucket->pod);

When I am starting apache with Worker mpm in debug mode and killing the
process with kill -term PID, it is not killing the process. Whereas same
code is working for prefork in debug mode to kill process with kill -term
PID.

If I want to kill process with worker in debug mode then how should I kill
it with kill -term PID command.

[users@httpd] After send status 200 response, process exited

[Hemant Chaudhary]

Hi,,
I started my apache successfully, but when I am sending request from
browser. Getting ERR_NO_RESPONSE in chrome.

I added LogLevel trace7 and collected the error log. What I have found
that, after successful response of requests(status-200), process is
exited. I thought its coredump therefore added directory for coredump also
but didn't get anything error .

What is the possible cause of this ?

 Response sent with status 200, headers:

Re: [users@httpd] Apache sending Content-Length 0

[Hemant Chaudhary]

Hi

Noticed one more thing, after sending status 200 with content length 0.
That particular child process dies. I thought its code dump but didn't find
any thing in dump directory.

Thanks
Hemant

Re: [users@httpd] Apache sending Content-Length 0

[Hemant Chaudhary]

Hi,

I tired to solve this error but didn't get any hint why it is coming.
Can you please help to solve the error. Which .c file manipulates the data
to send the response.
What are the reason to send status 200 with content-length 0.

Thanks
Hemant

Re: [users@httpd] Apache sending Content-Length 0

[Hemant Chaudhary]

Hi,
index.html is default apache html file.
It works!

I tried with cgi-script and other html files also, got the same error.
Thanks

[users@httpd] Apache sending Content-Length 0

[Hemant Chaudhary]

Hi,

When I am sending request from browser to client for basic "index.html", I
am getting error that
" Err_EMPTY_RESPONSE " in browser.

When I checked in the error log, found that response content length is 0.

You need someone who understands the platform you're running on to
debug why SIGUSR2 is received.

Hi All,

Can you please give some light why am I getting this issue(When sending
request,child dies and another child created).
I checked all loaded modules are working fine and only three modules are
static {core.c,http_core.c and mod_so.c}

Please help so that I can check where I need to check.

Hi All,

When I am starting apache, its started successfully and also listening to
that port.
But when I am sending request from browser to apache. It is not responding
and giving error AH00052.

[users@httpd] Worker MPM with kill

[Hemant Chaudhary]

Hi,

I started apache server which has worker as mpm in debug mode. I killed the
process with kill -9 then it kills the process and stop debug. But when I
am using kill -term PID then it is not killing process. Whereas  kill -term
PID is woking with prefork debug.

If I want to use kill -term PID in debug mode of worker then how to do that.

Thanks

[users@httpd] Aapche with c99 or c11

[Hemant Chaudhary]

Hi All,

I have compiled my apache with c99 and its working fine. I am planning to
use c11 compiler also.
Is there any impact will occur if I use c11 in place of c99 ?

Few more questions :
1) My apr is not supporting sendfile,random and mmap. What will be the
impact ?
2) When I am sending request from apache j-meter to my apache server then
for http is working fine with good TPS but for https, TPS is not good
because for most of the request it is taking connection time of
7000-9000ms. Is there anything am I missing in ssl configuration so that it
shouldn't connect continuously.

Thanks

Re: [users@httpd] Apache creates Semaphore

[Hemant Chaudhary]

Hi,

Yes kill -Term works for me even without patch of code.
I have one more doubt, I checked with ipcs command that there is only entry
of semaphore and no entry in shared memory.

If I have nothing in shared memory then why am I using semaphore?
What are the critical section in apache for which it requires semaphores.

Thanks

Re: [users@httpd] Apache creates Semaphore

[Hemant Chaudhary]

Hi,
I tried with the patch of code you have asked for prefork.c and worker.c.
But If I am closing apache gracefully then semaphore is not in shared
location but if I am killing process then still semaphore is there in
shared location.

Is there any way I get rid of semaphore because I want to run single
process only.

Thanks

Re: [users@httpd] Apache creates Semaphore

[Hemant Chaudhary]

Hi Yann,

When I am setting Mutex pthread or Mutex Pthread default in httpd.conf,
getting following error

AH00526: Syntax error on line 42 of
/home/hemant_super/hemant/dev_11oct/conf/httpd.conf:
Invalid Mutex argument pthread (Mutex mechanisms are: 'none', 'default',
'fcntl:/path/to/file', 'file:/path/to/file', 'sysvsem', 'sem')

When I tried with Mutex None, it is giving below error
/home/hemant_super/hemant/dev_11oct/bin: ./httpd -V
AH00526: Syntax error on line 42 of
/home/hemant_super/hemant/dev_11oct/conf/httpd.conf:
None is not allowed for mutex type default

Any idea why am I getting this error and how to solve it.

Thanks
Hemant

Re: [users@httpd] Apache creates Semaphore

[Hemant Chaudhary]

Hi Luca,

If I choose to go with MPM and to spawn single process then it will create
parent process and then child process where parent process monitor the
server and child process serve the request. But I need only one process
which works for both as parent and child which is achieved in httpd -X.
httpd -X creates one process which monitor apache as well as serves the
request.

Is it possible to disable mutex while configuring apache, so that it will
not create semaphores ?

Thanks
Hemant

Re: [users@httpd] Apache creates Semaphore

[Hemant Chaudhary]

Hi Yann,

For my product I need to run apache as single process. As httpd -X works
for me. But the issue is to stop httpd -X, we need to kill process. While
killing the process, semaphore exists in kernel directory.
If I repeat for 10-15 times, then it will give error like no space
available on device.
To solve this error, either I need to explicitly kill each semaphore id and
then start. So I thought not to create semaphore itself.
Therefore I commented following lines in worker.c

if ((rv = SAFE_ACCEPT((apr_snprintf(id, sizeof id, "%i",
i),ap_proc_mutex_create(&all_buckets[i].mutex,NULL, AP_ACCEPT_MUTEX_TYPE,
id, s, pconf, 0) {
   ap_log_error(APLOG_MARK, APLOG_CRIT | level_flags, rv, (startup
? NULL : s),  "could not create accept mutex");
 return !OK;

 After commenting above line, when I am starting httpd -X, it is giving
signal 31 error. When starting with httpd, its only starting parent and
killing child processes with signal 31 error.

What should I change if I want to start apache in debug mode and not to
create semaphore ?

Thanks
Hemant

[users@httpd] Apache creates Semaphore

[Hemant Chaudhary]

Hi,

Semaphore is used in multi process environment to share resources within
processes. But when I am starting apache in debug mode i:e single process
then still it creates semaphore. May I know the reason why it is creating
semaphore in debug mode also.

Thanks

[users@httpd] Apache with Semaphore

[Hemant Chaudhary]

Hi

When I am starting apache in debug mode then it creates semaphore. In
another terminal I am giving command "httpd -k stop" to stop apache. It
stops successfully but it is not removing semaphore.

Why apache is not sending signal to remove semaphore in debug mode after
stop it.

where am I going wrong.

location of tomcat - /home/ananya/apache-tomcat

Hi,

If I am using http and apache port then index.html of apache is displayed
not of ajp.

Do I need to change in ajp.conf and server.xml ?

Re: [users@httpd] Start apache with tomcat

[Hemant Chaudhary]

Hi

Few questions regarding your setup.
What is the Listen or port of your apache server ? Is it 8009 ?
Tomcat and apache should start in same or different port ?

After comment in server.xml, do we need to add anything there ?

What url should I use to access tomcat from browser ?

In my setup, I am starting tomcat at 5644 and apache at 5643 port.
and in ajp.conf using 5644(tomacat) port and using same port (5644) to
access from browser.

Thanks
Hemant

Re: AW: [users@httpd] Run apache without master [wd-vc]

[Hemant Chaudhary]

As i have seen in my system that master process also binds to port that i
have given in my configuration. Then how master process is binding to port
80 ? If i am running my apache other than root user then how can master
binds to port 80 ?

If i am running apache as root user then on any port my apache is working
but other than root user, i need to give port greater than 1024.

Thanks

Re: [users@httpd] Run apache without master [wd-vc]

[Hemant Chaudhary]

Yes true. I want to start only one process and it should not spawn child
processes.
In apache, we have master process and then it spawns child. After that
child serves requests by client.
My aim is to start master process and it should not spawn child as well as
it should serve requests from client.

Thanks

Re: [users@httpd] Run apache without master

Hi

I want to create different processes not forking from parent or anywhere.
It is still okay if parent process is started and parent process will not
fork child processes but parent should serve requests.

[users@httpd] User Auth type in apache-2.4.25

[Hemant Chaudhary]

Hi ,

I have user and group in my httpd.config. I want to use user in Auth type
instead of basic or digest. so that whenever customer try to open
directory, promt will ask to enter username and password and customer can
enter "user" as username and password.

Is there any option to achieve this or I need to write my own module for
this.


Cheers,

[users@httpd] Use MPM other than worker,event and prefork

[Hemant Chaudhary]

Hi folks,

I have installed apache-2.4.25 with worker module. But I want my apache to
start with my own module instead of worker module. In httpd.config, I have
commented LoadModule worker.so, but when I am staring apache, it is looking
for worker module.

Where I need to change code so that it will not look for worker module and
start with my module.

htdocs,logs to another location. Now I want to run my apache in new
location with these things only.
I changed path in httpd.conig and apachectl of new location, but while
starting it is starting apache in old location.

For example :
I ported apache on /home/hemant ..
I copied bin,conf,logs,htdocs,modules to /home/rakesh and in httpd.config I
replace all path of /home/hemant to /home/rakesh and changed port also. But
when I am starting apache, it is only starting at /home/hemant.

Without again configure,make and make install can I use it another location
?

Thanks
Hemant

Hi

It is not creating .so for mod_lua also. Only creating mod_lua.a and
mod_http2.a . But for other modules like mod_authn_file.so is create,
mod_mpm_worker.so etc.

Thanks
