Hi folks,
Newbie issues...I''m prototying an Apache/Mongrel configuration setup
as follows:
* Two Mongrel servers each serving a Rails application.
* Apache front-end.
* Linux system (CentOS)
* The plan is to create two virtual hosts.
/ETC/HOSTS LOOKS LIKE THIS:
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost egovm04
10.4.1.84 rss
10.4.1.84 railstest
HTTPD.CONF LOOKS LIKE THIS:
[snip]
NameVirtualHost 10.4.1.84
<VirtualHost rss>
ServerName rss
ServerAlias rss
RewriteEngine on
RewriteRule ^/rss(.*) http://10.4.1.84:5432$1
<http://10.4.1.84:5432/>[P]
ProxyPass / http://10.4.1.84:5432/
ProxyPassReverse / http://10.4.1.84:5432/
</VirtualHost>
<VirtualHost railstest>
ServerName railstest
ServerAlias railstest
RewriteEngine on
RewriteRule ^/railstest(.*)
http://10.4.1.84:8021$1<http://10.4.1.84:8021/>[P]
ProxyPass / http://10.4.1.84:8021/
ProxyPassReverse / http://10.4.1.84:8021/
</VirtualHost>
ISSUES
1. App 1 (rss) URL rewrite problem.
Typing ''http://10.4.1.84/rss'' <http://10.4.1.84/rss%27>
in the browser
correctly accesses app #1
(rss), HOWEVER...
This: ''http://10.4.1.84/rss/about''
<http://10.4.1.84/rss/about%27> finds the
right page, but the URL
is rewritten to this: ''http://10.4.1.84/about''
<http://10.4.1.84/about%27>
2. App # 2 not found.
Typing this: ''http://10.4.1.84/railstest''
<http://10.4.1.84/railstest%27>yields this:
Routing Error
Recognition failed for "/railstest"
This is a Rails message reported by app # 1( rss). So the (Apache)
server is not redirecting to the second Virtual Host (railstest).
Sorry for the question, I''m quite sure this is a setup problem on my
part.
Thanks,
Stan

You have the server names as "rss" and "railstest", don''t you have to access them via those hosts? http://rss/about Otherwise Apache defaults to the first VirtualHost definition.

Michael, Thanks for your help.> You have the server names as "rss" and "railstest", don''t you have toaccess them via those hosts? If I put these entries in my local hosts file: 10.4.1.84 rss 10.4.1.84 railstest they are then accessible from my browser using these addresses: http://rss http://railstest Adding them to my local computer''s hosts file is OK for my own use but there are a few other folks I''d like to show these to scattered throughout the site where I work and I''d like to find a way to do this other than modifying the hosts file on each system. One of the webmasters here thought it was sufficient to add the lines above to the _remote_ system''s hosts file and adding RewriteRules to each VirtualHost directive. The goal is to be able to do this from anywhere: http://10.4.1.84/rss http://10.4.1.84/railstest (But no;-) As you suggested, the remote system is taking the first VirtuaHost directive and is actually trying to find "railstest" on the first Mongrel site (rss) and, of course, not finding it. -Stan -------------- next part -------------- An HTML attachment was scrubbed...

Usually the value for that host header is taken from the location the user entered into the location bar. If possible you should get some admin to create dns records for these host names pointing to your IP, so that everyone can use these host names to access your apps.> > The goal is to be able to do this from anywhere: > > http://10.4.1.84/rss > http://10.4.1.84/railstestYou won''t get to work this with apache virtual hosts. instead you need to mount your apps under these paths, I didn''t ever do this but afair it has been discussed on the list several times.

The first (default) is to create the rewrite rules and the next two contain the ProxyPass... directives that map to the Mongrel servers.

> Did you get this resolved Stan?Yes, thanks. Basically a misunderstanding on my part about how VirtualHost directives work in the Apache httpd.conf file. I meant to post the solution because I''m curious as to whether I came up with the best approach. But it will have to wait until next week when I''m back in the office and have access to the Linux system (4-day weekend:-) I also discovered that the CSS styles aren''t rendering in the Rails app being served by Mongrel. I strongly suspect it''s a ReverseProxy setup issue. I''m a little hesitant to bring this up here since I don''t think it''s a Mongrel problem. But I''ll post some of the code and if it seems too OT, let me know. -Stan> Newbie issues...I''m prototying an Apache/Mongrel configuration setup > as follows: > > * Two Mongrel servers each serving a Rails application. > * Apache front-end. > * Linux system (CentOS) > * The plan is to create two virtual hosts.-------------- next part -------------- An HTML attachment was scrubbed...

I''m researching the reverseproxy situation on a side project, not mongrel-related, but relevant I believe. You might want to look at the following page... http://apache.webthing.com/mod_proxy_html/ This rewrites inline html urls when using reverse proxies and has an "extended" option that looks into linked stylesheets and JS files to rewrite urls there too. Dunno if this will help with your problem but it might connect a few neurons. matte - webmonkey matte at ruckuswireless.com Stan Baptista wrote:> On 2/16/07, *Stan Baptista* <stan.baptista at gmail.com > <mailto:stan.baptista at gmail.com>> wrote: > > > Did you get this resolved Stan? > > Yes, thanks.
