Reverse proxy with apache

Creating reverse proxy with appache is quite easy. The common scenario is that you want to redirect entire domain to internal application server. Steps: 1) install apache 2) Edit APACHE_HOME/conf/httpd.conf with following content:

Listen 80
#Listen 1080

LogLevel debug
#ProxyHTMLLogVerbose On

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule authz_core_module modules/mod_authz_core.so
LoadModule xml2enc_module modules/mod_xml2enc.so
LoadModule proxy_html_module modules/mod_proxy_html.so
LoadModule deflate_module modules/mod_deflate.so

<VirtualHost *>
 ProxyRequests OFF
 ProxyPreserveHost On
 
 ProxyPass / ajp://127.0.0.1:8009/
 ProxyPassReverse / ajp://127.0.0.1:8009/

 #ProxyPass /app/ ajp://127.0.0.1:8009/app/
 #ProxyPass /app/ ajp://127.0.0.1:8009/app/
 #ProxyHTMLURLMap  / /app/ 

</VirtualHost>

3) On the application server (Tomcat/JBoss) deploy your app in the root context. For JBoss use jboss-web.xml with following content:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web>
<context-root>/</context-root>
</jboss-web>

Also do not forget to disable the default root application from JBOSS_HOME/standalone/configuration/ set enable-welcome-root to false

<virtual-server name="default-host" enable-welcome-root="false">
