Redis-Server

Install Redis-Server for the system distribution.

$ apt install redis-server

Redis-Server advises to set vm.overcommit_memory=1 in the system conf file.

Edit the Redis config file and add the directive.

$ nano /etc/sysctl.conf

vm.overcommit_memory=1

Check the section on GRUB for additional settings to be made for Redis-Server.

Once Redis has been installed, it can be checked by running the redis command line.

$ redis-cli

If redis server is running it will provide a prompt. Enter the following command to give information on the server.

If redis-cli provides an output similar to above, then all would appear good with Redis-Server. At the redis-cli prompt, type quit to return to console prompt.
