Before using this script to manage, you need to configure the following kernel parameters, otherwise the Redis script will report an error when restarting or stopping redis, and cannot automatically synchronize data to disk before stopping the service:

The code is as follows:

# vi / etc/sysctl.conf

Vm.overcommit_memory = 1

Then the application takes effect:

The code is as follows:

# sysctl-p

Then add services and boot up:

The code is as follows:

# chmod 755 / etc/init.d/redis

# chkconfig-add redis

# chkconfig-level 345 redis on

# chkconfig-list redis

Script source code:

#! / bin/bash## redis- this script starts and stops the redis-server daemon## chkconfig:-80 1 minutes description: Redis is a persistent key-value database# processname: redis-server# config: / usr/local/redis/etc/redis.conf# pidfile: / usr/local/redis/var/redis.pidsource / etc/init.d/functionsBIN= "/ usr/local/redis/bin" CONFIG= "/ usr/local/redis/etc/redis.conf" PIDFILE= "/ usr/local/redis / var/redis.pid "# Read configuration [- r" $SYSCONFIG "] & & source" $SYSCONFIG "RETVAL=0prog=" redis-server "desc=" Redis Server "start () {if [- e $PIDFILE] Then echo "$desc already running...."
