Complete!

Step 3 – Make few changes in  configuration so Varnish can run properly. By default, the configuration is set as following:

 

Now scroll down and you can see the options to Adjust the values :

 

 

 

 

 

 

 

 

Edit all the values as recommended . Also you can see that Varnish Storage Size recommendation is 1 GB . Make sure you have more than 1 GB RAM on your Server. If you have 1 GB RAM then you can set it to 256MB or 512 MB. In my case I will set it as 1GB as i have 5 GB ram on the server.

 

 

 

 

 

 

Click on Save Changes . You can see the message Data Updated.

 

 

 

 

This means CentOs Web Panel has updated all Virtual Host entries adjusting its port to 82 (Apache).
