Let’s take a look at how our Cloudflare Support Team is ready to help customers with the Cloudflare Railgun setup.

About Cloudflare Railgun setup

Railgun ensures a fast connection between the origin server and the Cloudflare network. It is a WAN optimization technology that is available to Cloudflare Business and Enterprise customers in addition to Optimized Partners. Furthermore, we have to install Cloudflare Railgun Listener software on our web server’s network for this to work.

Additionally, Cloudflare Railgun is a single daemon. It runs on a 64-bit system and relies on alternative compression techniques to speed up WAN performances immensely. Moreover, it proxies traffic via a special protocol that would otherwise travel between the origin server and Cloudflare over HTTP.

The per-requirements for setting up Cloudflare Railgun include:

• Railgun Activation Token from Cloudflare
• Sudo access for the webserver

How to setup Cloudflare Railgun

1. To begin with, log in to the webserver where we want to install the Cloudflare Railgun listener.
2. Then, check the CentOS with the following command:

   cat /etc/*release*
3. Next, update the existing packages with this command:

   yum update -y
4. After that, we will install RPM in order to add the repository as seen below:

   sudo rpm -ivh http://pkg.cloudflare.com/cloudflare-release-latest.el<VERSION>.rpmExample – CentOS 7 – sudo rpm -ivh http://pkg.cloudflare.com/cloudflare-release-latest.el7.rpm

   Remember to replace <VERSION> with the corresponding release version number.
5. Then install the Cloudflare railgun package:

   yum install railgun-stable -y
6. Next, we have to edit the Memcached config file at /etc/sysconfig/memcached. We have to edit the file in order to make Memcached run on Socket rather than Port.

   Furthermore, we have to change the cache size to 4096MB, the number of maximum connections to 20000 as well as change the OPTIONS variable in the /tmp directory to 777.
7. After that, edit the Railgun config file at /etc/railgun/railgun.conf to add the Activation token to the activation.token variable and the webserver public IP to activation.railgun_host variable.

   Website owners can get the Activation Token at www.cloudflare.com/a/account/my-account and Cloudflare Hosting Partners can find it at this link .

   Furthermore, we have to comment out memcached.servers variable with the localhost IP and port and then set the socket file path with memcached.servers variable as seen below:

   memcached.servers = /tmp/memcached.sock
8. Next, start both Memcached and Railgun

   service memcached start
   service railgun start
9. After that all Memcached and Cloudflare Railgun to the startup file:

   chkconfig memcached on
   chkconfig railgun on
