Start Varnish Web Accelerator
To start Varnish at system start-up, type the following command to make it start at system boots.
# chkconfig –level 345 varnish on
Configure Varnish
/etc/sysconfig/varnish
Install Redis and PhpRedis
https://gist.github.com/nghuuphuoc/7801123
# yum –enablerepo=epel,remi,rpmforge install redis
Finally, we need to add the service to chkconfig, set it to auto-start, and actually start the service:
chkconfig –add redis
chkconfig redis on
service redis start
Again, test the installation of Redis:
redis-cli ping
If the result is ‘PONG’, then installation has been successful.
