Deploying Redis on Linux

Although you can install Redis on almost all modern operating systems (OS) by compiling its source code, Linux is the most common OS running Redis. Before you start the Redis instance, it is often necessary to set some Linux kernel and OS level parameters to proper values, in order to obtain the maximum performance in the production environment. In this recipe, we will introduce some vital kernel and OS parameters or settings for Redis.

To persist these parameters add the following:

echo vm.overcommit_memory=1" >> /etc/sysctl.confecho "vm.swappiness=0" >> /etc/sysctl.conf
