Tomcat5 + Apache on Centos

Install Tomcat5:
    The easy way is yum install tomcat5 tomcat5-webapps

Testing:
    netstat -ntlp  <-----------Check the default 8080 port is ready
    http://localhost:8080/   <------Test the url

If you don't wanna join tomcat to apache2 you can stop here.

Join Tomcat to Apache2
There are several ways to join tomcat to apache2

• jk  (mod_jk)
• http_proxy   (mod_proxy)
• proxy_ajp    (mod_proxy_ajp)

Now I use the easiest way - ajp_proxy:

vi /etc/httpd/conf.d/proxy_ajp.conf

LoadModule proxy_ajp_module modules/mod_proxy_ajp.so

ProxyPass /tomcat/ ajp://localhost:8009/

Double check the proxy_ajp.conf have included in httpd.conf

restart httpd and test with url "http://localhost/tomcat/"
