In this quick guide, you will install a free Redis server in what takes just about a minute.
After you have followed the steps, you will have your Redis server instance running as a service on your host. You can use it to power the cache of your WordPress site with appropriate plugins that support Redis.
You can use the Redis server to power the cache and get lightning fast search and filter results with the latest release of the WooCommerce Product Search extension, the Search Engine which is essential for every WooCommerce store.
As the first step, we update the package repository:
$ sudo apt update
Now we will install the Redis server package:
$ sudo apt install redis-server
As we want to use this with WordPress, we also install the Redis PHP extension, so plugins can use it easily:
$ sudo apt install php-redis
Let’s check which version of the Redis server is installed:
$ redis-server –-version
We also want to make sure that the server is running as a service, so it is there in case the host needs to restart:
$ sudo service redis-server status
The server comes with a command-line client
redis-cli which you can use to connect to your Redis server and interact with it. You can also use it to get information on the server status directly:
$ redis-cli info
While the Redis server is running, it is useful to check its Keyspace stats, one of several sections of information that the tool provides. It’s an easy way to verify that things are moving, i.e. data is actually being cached. The following command will show the current Keyspace stats:
$ redis-cli info Keyspace
We assume that the Redis server is running on the same host as your web server. The default connection settings allow to connect to it to port
Great! Your Redis server is eager to work!
