3. Set as Linux service

Copy the Redis service script file to the/ETC/RC.D/INIT.D directory;

1	$ cp./utils/redis_init_script/etc/rc.d/init.d/redis

Modify the Redis service script, Vi/etc/rc.d/init.d/redis; modified/etc/rc.d/redis as follows:

12345678910111213141516171819202122232425262728293031323334353637383940414243

Add the/etc/rc.d/init.d/redis script to the service with the following command:

1	$ chkconfig -add redis

Set boot up

1	$ chkconfig redis on
