mod_proxy for apache/redhat not working

Question

We have the following scenario:

• First APP: http://example.com:8090/access/app1
• Second APP: http://example.com:8090/access/app2

We want to configure apache mod_proxy to assign:

• http://app1.example.com >> http://example.com:8090/access/app1
• http://app2.example.com >> http://example.com:8090/access/app2

---

We tried the following without success:

<VirtualHost app1.example.com:80> ServerName app1.example.com ProxyPass / http://example.com:8090/access/app1/ ProxyPassReverse / http://example.com:8090/access/app1/ </VirtualHost> <VirtualHost app2.example.com:80> ServerName app2.example.com ProxyPass / http://example.com:8090/access/app2/ ProxyPassReverse / http://example.com:8090/access/app2/ </VirtualHost> 

Saved this into /etc/httpd/conf.d/myconfig.conf, then restart apache sudo service http restart.

When using a browser and writting http://app1.example.com the default Apache-Welcome-Page appears, but not our app1 page. Looks like the mod_proxy config is not working.

Setting errorlevel to DEBUG will show the following event in error_log:

[Tue Aug 07 14:18:04.748775 2018] [autoindex:error] [pid 1985] [client x.x.x.x:58843] AH01276: Cannot serve directory /var/www/html/: No matching DirectoryIndex (index.html) found, and server-generated directory index forbidden by Options directive

Any help will be appreciated

Answer 1

Configure your virtual host file as follow

<VirtualHost *:80> ServerName app1.example.com ProxyPass /app1 http://example.com:8090/access/app1/ ProxyPassReverse /app1 http://example.com:8090/access/app1/ </VirtualHost> <VirtualHost *:80> ServerName app2.example.com ProxyPass /app2 http://example.com:8090/access/app2/ ProxyPassReverse /app2 http://example.com:8090/access/app2/ </VirtualHost> 

Answer 2

Two things:

1) comment out or empty the conf.d/welcome.conf file (do not remove it though, or it will get reinstated when you next patch httpd

2) httpd -S is a great friend when considering virtual server issues. This will output where in your configuration your virtualhosts are defined (and which ones are default)

And a bonus: I see you are using port 8090, which makes me think you are possibly dealing with Atlassian products. If you are dealing with Confluence with the Synchrony collaborative editing component, I can perhaps give you some config for the websocket stuff (Atlassian’s documentation is confusing when it comes to reverse proxy configuration )
