Run Multiple Apache On Single Host

In this blog post we are going to discuss on how to run two Apache instances on single Linux host.

We already have one Apache installed and serving the static content. The Apache is installed at the following location:

/etc/httpd

Let`s copy the directory /etc/httpd to /etc/togohttpd

  cp -pr /etc/httpd  /etc/togohttpd   

Now, as we have copied the old Apache web-server to a new location /etc/togohttpd. We need to make the changes to the configuration file.

cd  /etc/togohttpd and open the httpd.conf file in a vi editor and make changes to the following values:

ServerRoot “/etc/httpd”  TO ServerRoot “/etc/togohttpd”

Listen 80 TO Listen 82

PidFile run/httpd.pid TO PidFile run/togohttpd.pid

Save and close the file.

In the next step we are going to copy the RHEL httpd configuration file.

 cp -pr /etc/sysconfig/httpd  /etc/sysconfig/togohttpd 

In the next step, let`s copy the script /etc/init.d/httpd  TO /etc/init.d/togohttpd

 cp -pr  /etc/init.d/httpd   /etc/init.d/togohttpd 

In this step, Link the /usr/sbin/httpd TO /usr/sbin/togohttpd

 ln -s  /usr/sbin/httpd   /usr/sbin/togohttpd 

Open the file togohttpd under /etc/sysconfig/ and enter the following lines:

## CUSTOM SETTINGS ##
HTTPD=/usr/sbin/togohttpd
OPTIONS="-f /etc/togohttpd/conf/httpd.conf"
LOCKFILE=/var/lock/subsys/togohttpd
PIDFILE=/var/run/togohttpd.pid

Open the togohttpd file under /etc/init.d and replace httpd to togohttpd.

The command used to start/stop httpd and togohttpd service could be:

• /etc/init.d/httpd {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}
• /etc/init.d/togohttpd {start|stop|restart|condrestart|reload|status|fullstatus|graceful|help|configtest}
