I've been trying to resolve this for over 2 weeks, but no one seems to
be able to tell me what's wrong. Maybe you folks can help me.
(this is a copy of a post I made on a Usenet alt.apache.configuration,
with no responses)
I'm running Ubuntu 6.06LTS, Apache 2.0.55, and WebMin 1.36. I've been
trying to set up static content with server-side includes to be
delivered by Apache, but reverse proxying for Rails application
reqeusts on a local (soon to be remote) Mongrel server at port 8000. I
also wanted to have any request that is received without a specific
file to be redirected to index.shtml.
I've been able to get everything running EXCEPT the reverse proxy with
the following config:
ServerName myapp.com
ServerAlias www.myapp.com
ServerAdmin [EMAIL PROTECTED]
DocumentRoot /var/www/rails/myapp/public
ErrorLog /var/www/myapp/log/apache2.log
RewriteMap railservers rnd:/var/www/rails/map.txt
<Directory /var/www/rails/myapp/public/>
Options FollowSymLinks +Includes +ExecCGI
AllowOverride None
Order allow,deny
Allow from all
RewriteEngine On
RewriteRule ^$ index.shtml [QSA]
RewriteRule
"^/(images|stylesheets|javascripts|pictures|graphics)/?
(.*)" "$0" [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^/(.*)$ http://localhost:8000/$1 [P,L]
</Directory>
RewriteLog "/var/www/myapp/log/rewrite.log"
RewriteLogLevel 0
#placed in global parameter file
# Avoid open server to proxying
ProxyRequests Off
# Pass other requests to mongrel instance
#ProxyPass / http://localhost:8000/
# Enable reverse proxying
ProxyPassReverse / http://localhost:8000/
# Let apache pass the original host not the ProxyPass one
ProxyPreserveHost On
AddType text/html .shtml
AddOutputFilter INCLUDES .shtml
LogLevel debug
CustomLog /var/log/apache2/access.log "combined"
ServerSignature On
I have a RewriteMap defined to allow me to set up a cluster of
Mongrels once I get one working, since 2.0 doesn't have the balancer
module.
Webmin puts the proxy config in a separate file called proxy.conf
which contains:
<IfModule mod_proxy.c>
#turning ProxyRequests on and allowing proxying from all may
allow
#spammers to use your proxy to send email.
ProxyRequests Off
<Proxy *>
Order deny,allow
#Deny from all
Allow from all
</Proxy>
# Enable/disable the handling of HTTP/1.1 "Via:" headers.
# ("Full" adds the server version; "Block" removes all outgoing
Via:
headers)
# Set to one of: Off | On | Full | Block
ProxyVia Off
# To enable the cache as well, edit and uncomment the following
lines:
# (no cacheing without CacheRoot)
CacheRoot "/var/cache/apache2/proxy"
CacheSize 5
CacheGcInterval 4
CacheMaxExpire 24
CacheLastModifiedFactor 0.1
CacheDefaultExpire 1
# Again, you probably should change this.
#NoCache a_domain.com another_domain.edu joes.garage_sale.com
</IfModule>
I've tried several things:
-put the rewriteengine on directive outside of the directory block: I
was unable to access any page that wasn't specifically requested.
-defined "ProxyPass / http://localhost:8000/": was unable to access
anything (no permission to access) even though permissions are set to
775
-turned on rewritelog. here are the results for a www.myapp.com/state/list
request:
(3) add path info postfix: /var/www/rails/myapp/public/state -> /var/
www/rails/myapp/public/state/list
(3) strip per-dir prefix: /var/www/rails/myapp/public/state/list ->
state/list
(3) applying pattern '^$' to uri 'state/list'
(3) add path info postfix: /var/www/rails/myapp/public/state -> /var/
www/rails/myapp/public/state/list
(3) strip per-dir prefix: /var/www/rails/myapp/public/state/list ->
state/list
(3) applying pattern '^/(images|stylesheets|javascripts|pictures|
graphics)/?(.*)' to uri 'state/list'
(3) add path info postfix: /var/www/rails/myapp/public/state -> /var/
www/rails/myapp/public/state/list
(3) strip per-dir prefix: /var/www/rails/myapp/public/state/list ->
state/list
(3) applying pattern '^/(.*)$' to uri 'state/list'
(1) pass through /var/www/rails/myapp/public/state
It seems that the rewrite is working up to the rewritecond statement.
It parses the statement pattern correctly, but the file state/list
does not exist, so the condition "!-f" should pass the request to
Mongrel, but it seems to pass it to Apache, who doesn't find the file
"state/list" and gives a 404 error, unless I'm reading the logs wrong!
I wish I had detailed instructions on how to read a rewritelog and
what the codes mean. I haven't been able to find them anywhere.
The proxy modules are loaded, so there must be something else I'm not
doing. I've been working on this for 2 weeks. Any suggestions will be
appreciated!
