Configure Magento to use Varnish

To configure Magento to use Varnish:

1. Log in to the Magento Admin as an administrator.
2. Click STORES > Configuration > ADVANCED > System > Full Page Cache.
3. From the Caching Application list, click Varnish Caching.
4. Enter a value in the TTL for public content field.

5. Expand Varnish Configuration and enter the following information:

   Field	Description
   Access list	Enter the fully qualified host name, IP address, or Classless Inter-Domain Routing (CIDR) notation IP address range for which to invalidate content. More information
   Backend host	Enter the fully qualified host name or IP address and listen port of the Varnish backend or origin server; that is, the server providing the content Varnish will accelerate. Typically, this is your web server. More information
   Backend port	Origin server's listen port.

6. Click Save Config.

mysql -u root -p -D magento -e "INSERT INTO core_config_data ( scope, scope_id, path, value ) VALUES ( 'default', '0', 'system/full_page_cache/caching_application', '2') ON DUPLICATE KEY UPDATE value = 2;"

Export a Varnish configuration file

This step is optional and should only be necessary if you changed the backend host and/or port number that you specified in the previous section.

To export a Varnish configuration file from the Admin panel:

1. Click one of the export buttons to create a default.vcl you can use with Varnish.

   For example, if you have Varnish 4, click Export VCL for Varnish 4

   The following figure shows an example.
   
   

2. Replace your existing default.vcl with the one you just exported.

3. We recommend you open default.vcl and change the value of acl purge to the IP address of the Varnish host. (You can specify multiple hosts on separate lines or you can use CIDR notation as well.)

   For example,

   acl purge {
      "localhost";
   }
   

4. Restart Varnish and your web server:

   service varnish restart
   service httpd restart
