Install RedisPermalink

In this section you’ll add the EPEL repository, and then use it to install Redis.

1. Add the EPEL repository, and update YUM to confirm your change:

   sudo yum install epel-release
   sudo yum update
   

2. Install Redis:

   sudo yum install redis
   

3. Start Redis:

   sudo systemctl start redis
   

   Optional: To automatically start Redis on boot:

   sudo systemctl enable redis
   

Verify the InstallationPermalink

Verify that Redis is running with redis-cli:

redis-cli ping

If Redis is running, it will return:

PONG

Configure RedisPermalink

In this section, you’ll configure some basic persistence and tuning options for Redis.

Persistence OptionsPermalink

Redis provides two options for disk persistence:

• Point-in-time snapshots of the dataset, made at specified intervals (RDB).
• Append-only logs of all the write operations performed by the server (AOF).

Each option has its own pros and cons which are detailed in the Redis documentation. For the greatest level of data safety, consider running both persistence methods.

Because the Point-in-time snapshot persistence is enabled by default, you only need to set up AOF persistence:

1. Make sure that the following values are set for the appendonly and appendfsync settings in redis.conf:

   /etc/redis.conf

   1 2	appendonly yes appendfsync everysec

2. Restart Redis:

   sudo systemctl restart redis
