Installing apsaradb for Redis in CentOS is also relatively simple. You can perform the operations step by step without errors.

1. Switch/usr/srcDirectory (if you install it in another directory, You need to modify the path later), download Redis, the latest version is 2.8.13.

1. Cd/usr/src
2. Wget http://download.redis.io/releases/redis-2.8.13.tar.gz

2. decompress the package and switch the directory.

1. Tar xzf redis-2.8.13.tar.gz
2. Cd redis-2.8.13

Add a row to the file and save:

1. Vm. overcommit_memory = 1

Run:

13. EXEC =/usr/local/bin/redis-server
14. REDIS_CLI =/usr/local/bin/redis-cli
15. PIDFILE =/var/run/redis. pid
16. CONF = "/usr/src/redis-2.8.13/redis. conf"
17. Case "$1" in
18. Start)
19. If [-f $ PIDFILE]
20. Then
21. Echo "$ PIDFILE exists, process is already running or crashed"
22. Else

24. $ EXEC $ CONF
25. Fi

27. Then

32. If [! -F $ PIDFILE]
33. Then

35. Else
36. PID = $ (cat $ PIDFILE)
37. Echo "Stopping ..."
38. $ REDIS_CLI-p $ REDISPORT SHUTDOWN
