Reference: "Redis installation record under CentOS 6.5"

If you only execute Make, you also need to execute the following command to configure startup:

[Plain] view plaincopy

1. Sudomakeinstall

During the install, The redis command will be copied to/usr/local/bin.

Copy the configuration file to the/etc directory.

[Plain] view plaincopy

1. Cpredis. conf/etc

To create a user and log directory, we recommend that you create a separate user for Redis and create a new data and log folder.

2. Sudomkdir-p/var/lib/redis
3. Sudomkdir-p/var/log/redis
4. Sudochownredis. redis/var/lib/redis
5. Sudochownredis. redis/var/log/redis
