Configure Varnish (TM) for WordPress
To make Varnish ™ receive the HTTP requests on port 80, Apache needs to be moved to port 81. To do so, follow these steps:
- Access your WordPress server through SSH.
Rename the Varnish ™ config file as shown below:
$ sudo cp /opt/bitnami/varnish/conf/wordpress.vcl.disabled/wordpress.vcl.disabled /opt/bitnami/varnish/conf/default.vcl
Change the listening ports in Apache by executing the commands below:
$ sudo sed -i 's/Listen 80/Listen 81/' /opt/bitnami/apache/conf/httpd.conf $ sudo sed -i 's/:80/:81/' /opt/bitnami/apache/conf/vhosts/00_status-vhost.conf $ sudo sed -i 's/:80/:81/g' /opt/bitnami/apache/conf/vhosts/wordpress-vhost.conf
NOTE: These instructions are for the default Bitnami Apache configuration. If you have configured new Apache virtual hosts, you have to update those definitions accordingly.
Restart all services:
$ sudo service bitnami restart
