At a higher level of implementation, it can also provide high availability via Redis Sentinel including monitoring, notifications automatic failover, and partitioning across multiple Redis nodes. If you want to speed up your dynamic applications or websites, using Redis to cache and return frequently requested items may help.

How to configure Redis on Ubuntu Linux
Now that the server is installed and verified, use the steps below to configure remote login and adjust the Ubuntu firewall. By default, Redis doesn’t allow access from remote locations ( access from different servers/clients). All-access is restricted to the local host of the server it is installed on. ( example: 127.0.0.1). In most environments, Redis Server and the applications it supports are running on a single server. In this situation, no remote access is necessary, since all the communications are done on a single host computer. However, if both the Redis server and applications using it are on separate hosts, then remote access will be required. To allow remote access, open the Redis configuration file by running the commands below: Then change the highlighted line as shown below. replacing 127.0.0.1 with all zeros ( 0.0.0.0 ) or restricting access to a specific host IP that will need access to Redis. Save the file and exit. After making the changes to the file, restart the Redis service. Verify that Redis is listening for all connections on 0.0.0.0 by running the commands below: You should get an output as shown below: If you’re also running an Ubuntu firewall, simply add the policy below to allow all hosts on your subnet ( 192.168.0.0 ) access to the Redis server and port number. That should do it. To test if Redis hosted on IP address 192.168.0.2 is responding to remote hosts. type the commands below from the remote server. The Redis server should respond with a pong If you receive a correct reply, then all is done. Conclusion: This post showed you how to install Redis on Ubuntu Linux.
