Re: reverse proxy in depth tutorial?
On Thu, 24 Jul 2003, Garrett Goebel wrote: Most everything I'm stumbled upon has been short on detail and examples. For instance, I never found an example of how to just reverse proxy everything for a given backend server. All the examples I saw showed how to proxy something like http://foo/bar but not http://foo. Eventually I came up with the following: [Reverse Proxy] ... Listen 192.168.1.1:80 RewriteEngine on RewriteRule ^/?(.*) http://127.0.0.1:80/$1 [P] ProxyPassReverse / http://127.0.0.1:80/ ... [Backend Server] ... Listen 127.0.0.1:80 ... Is this kosher? Is there a better way to do this? A way to do it without mod_rewrite using only mod_proxy directives? It can be done easy without mod_rewrite: ProxyPass / http://127.0.0.1:80/ ProxyPassReverse / http://127.0.0.1:80/ Are there any strong arguments against using a mod_proxy/mod_rewrite httpd accelerator? Or preferred alternatives? I can not say about Apache2's mod_proxy (I do not use Apache2) but Apache 1.3's one has several drawbacks when it serves the big responses for the slow clients. It reads the backend response and synchronously sends it to client. The maximum size of the data that can be read from backend without delay is ProxyIOBufferSize + frontend kernel TCP send buffer + frontend kernel TCP recieve buffer + backend kernel TCP send buffer. Kernel TCP buffers are usually 16K-64K but can be made bigger. To eliminate many mod_proxy drawbacks I had written more than two years ago mod_accel module to do the reverse-proxing. mod_accel allows to configure read buffer in memory but if the response is bigger then it saves it to the temporary file and frees the backend as soon as possible. mod_accel has directives to configure the caching backend responses, to limit the connections to some backend to avoid the starvation of other hosts and many other features. mod_accel is clean module and is used for two years on several Russian loaded sites. One of them serves 100 requests per seconds without any segfaults. The main mod_accel drawback for non-Russian users is that there's no complete English documentation. Here is very incomplete documentaion http://dapi.chaz.ru/articles/plain/en/mod_accel.xml Also there're some English links on http://sysoev.ru/en/ Using the loopback for the backend has the security advantage of completely isolating the backend from any direct communication with external hosts. How do I keep the backend on 127.0.0.1 _and_ handle name based virtual hosts? Using mod_proxy you can set up backend listening on several loopback addresses: 127.0.0.1, 127.0.0.2, etc. Of course, you need to configure these additional addresses in OS before the use. Also backend can listen on several ports and the single address: 127.0.0.1:8000, 127.0.0.1:8001, etc. Here is example for two virtual hosts on several addresses, note that 1) the frontend servers are name based while the backend ones are IP based; 2) ServerName of the virtual server pairs are the same. [Reverse Proxy] NameVirtualHost frontend VirtualHost frontend ServerName name1 ProxyPass / http://127.0.0.1:80/ ProxyPassReverse / http://127.0.0.1:80/ ... /VirtualHost VirtualHost frontend ServerName name2 ProxyPass / http://127.0.0.2:80/ ProxyPassReverse / http://127.0.0.2:80/ ... /VirtualHost [Backend Server] UseCanonicalName on VirtualHost 127.0.0.1 ServerName name1 ... /VirtualHost VirtualHost 127.0.0.2 ServerName name2 ... /VirtualHost Using mod_accel you can use the same scheme and also there's another way: [PH] flag of the AccelPass directive preserves Host header. [Reverse Proxy] AccelPass / http://127.0.0.1/ [PH] [Backend Server] UseCanonicalName on NameVirtualHost 127.0.0.1 VirtualHost 127.0.0.1 ServerName name1 ... /VirtualHost VirtualHost 127.0.0.1 ServerName name2 ... /VirtualHost What are the issues with regard to virtual hosting and ssl? All your SSL-enabled sites have to be IP-based. Any tips on keeping the config files maintainable? For instance if I'm doing a mason site with co-branding through multiple component roots... What would minimal configurations for proxy and backend servers look like in order to redirect an externally exposed ip address on the proxy to a backend on 127.0.0.1 and still preserve the name based virtual hosts? It that possible? Yes it's possible, see previous examples. What are the variations, tradeoffs, and issues scaling it out to multiple physical servers? etc. mod_accel supports the primitive load balancing and fault tolerance using DNS. mod_proxy in Apache 1.3 also has code that allows to connect to the next server returned by DNS but this code is broken - it uses the same socket to connect to the next backend and this always fails.

[Unfortunately, I've had to comment-out the first part of that if
block, because I got an unresolved external symbol error relating
to the
PerlIO_isutf8() function otherwise (which may be because that function
isn't documented in the perlapio manpage).]
mod_perl 1.x doesn't use perlio, hence you have this problem. adding:
#include perlio.h
should resolve it I think.
No. The error was unresolved external symbol, which means that the
compiler is happy (it evidently has pulled in perlio.h, or something
else that declares PerlIO_isutf8() as extern ...), but that the
linker couldn't find the definition of that function.
(Check: If I change PerlIO_isutf8 to PerlIO_isutf (deliberate
typo) then I get a different error - undefined; assuming extern
returning int - because now no declaration has been supplied.)
Listing the symbols exported from perl58.lib shows that PerlIO_isutf8
is *not* one of them. So where's the definition supposed to come from?
I'll ask about this on the perlxs mailing list, I think.
Having asked about this, it turns out that the problem was
PerlIO_isutf8() not being exported from perl58.lib on Windows (and other
platforms where the symbols to export have to be explicitly listed).
I sent a patch off to p5p which fixes this
(http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2003-07/msg01096.html),
and it has been integrated as #20203.
So presumably this will not be a problem in the upcoming perl-5.8.1, but
how do we cope with the perl-5.8.0 case?
I've attached a new patch (against mod_perl-1.28) which (I believe)
fixes the UTF-8 problem, but it won't build on Windows with perl-5.8.0
without #20203.

It's the path where Apache was installed to. I'm not on RH so I'm not sure
where it installs it to. But from looking at the RH rpms, it spreads things

There is a RH rpm package which includes the build instructions specific to

at least:

You can also try to use the latest src.rpm from rawhide, I'm not sure how

At the end of each request, Apache::DBI issues a rollback for any uncommitted transactions. That means that the only things that could be committed are things that you did earlier in the current request.

I've added a new section to the porting tutorial that shows examples of how to handle this situation: http://perl.apache.org/docs/2.0/user/porting/porting.html#Method_Handlers I changed the code for Apache-AuthenNTLM-2.04 to reflect your example, and it works great! Thanks for the pointer :) speeves cws
re: AuthenNTLM - help
Shannon, i put it working on Solaris, mod_perl, NTLM and mod_jk2 (to comunicate with Tomcat), but unfortunatily, it just works when i access from windows 9x and Linux. When i access by NT/2000/XP, it just doesn't work at all (no validation). So, i decide, for a while, make it work on Linux! I am using Conectiva 8, and it is working fine. Thanks.

Have you any idea about what is wrong? The version of apache with mod_ssl i took from sunfreeware, mod_perl and ApacheAuthenNTLM i compiled by myself. Sorry, I don't know why this might be happening... Are you running through a proxy server? I have seen a lot of problems when ntlm authentication through a proxy server... speeves cws I am forwarding this to the modperl list... Please include the list in your replies. thanks, speeves cws
DProf on Mac OS X
Has anyone gotten this to work on OS X? From http://perl.apache.org/docs/1.0/guide/performance.html % setenv PERL5OPT -d:DProf % httpd -X -d `pwd` ... make some requests to the server here ... % kill `cat logs/httpd.pid` % unsetenv PERL5OPT % dprofpp I've used this profiling technique on other Unix-like OSes, so I think I'm doing it right. But on OS X, I get a tiny tmon.out file that never grows after the initial server startup. I don't see any error messages or log lines. When I try to use Apache::DProf, I get a bus error on any request: [Fri Jul 25 18:52:48 2003] [notice] child pid 3840 exit signal Bus error (10) My setup: apache 1.3.27, mod_perl 1.27 % uname -a Darwin derkins 6.6 Darwin Kernel Version 6.6: Thu May 1 21:48:54 PDT 2003; root:xnu/xnu-344.34.obj~1/RELEASE_PPC Power Macintosh powerpc % perl -V Summary of my perl5 (revision 5.0 version 8 subversion 0) configuration: Platform: osname=darwin, osvers=6.0, archname=darwin uname='darwin derkins 6.0 darwin kernel version 6.0: sat jul 27 13:18:52 pdt 2002; root:xnuxnu-344.obj~1release_ppc power macintosh powerpc ' config_args='' hint=recommended, useposix=true, d_sigaction=define usethreads=undef use5005threads=undef useithreads=undef usemultiplicity=undef useperlio=define d_sfio=undef uselargefiles=define usesocks=undef use64bitint=undef use64bitall=undef uselongdouble=undef usemymalloc=n, bincompat5005=undef Compiler: cc='cc', ccflags ='-pipe -fno-common -no-cpp-precomp -fno-strict-aliasing', optimize='-O3', cppflags='-no-cpp-precomp -pipe -fno-common -no-cpp-precomp -fno-strict-aliasing' ccversion='', gccversion='3.1 20020420 (prerelease)', gccosandvers='' intsize=4, longsize=4, ptrsize=4, doublesize=8, byteorder=4321 d_longlong=define, longlongsize=8, d_longdbl=define, longdblsize=8 ivtype='long', ivsize=4, nvtype='double', nvsize=8, Off_t='off_t', lseeksize=8 alignbytes=8, prototype=define Linker and Libraries: ld='cc', ldflags =' -flat_namespace -L/usr/local/lib' libpth=/usr/local/lib /usr/lib libs=-lgdbm -ldbm -lm -lc perllibs=-lm -lc libc=/usr/lib/libc.dylib, so=dylib, useshrplib=true, libperl=libperl.dylib gnulibc_version='' Dynamic Linking: dlsrc=dl_dyld.xs, dlext=bundle, d_dlsymun=undef, ccdlflags=' ' cccdlflags=' ', lddlflags=' -flat_namespace -bundle -undefined suppress -L/usr/local/lib' Characteristics of this binary (from libperl): Compile-time options: USE_LARGE_FILES Built under darwin Compiled at Aug 24 2002 14:44:56 %ENV: PERL5DB=use Devel::DProf PERL5OPT=-d:DProf PERL_READLINE_NOWARN= @INC: /Library/Perl/darwin /Library/Perl /Library/Perl/darwin /Library/Perl /Library/Perl
