Centos如何设置开机自动启动Redis

下载Redis

在Linux下安装Redis非常简单，具体步骤如下（官网有说明）：

下载源码，解压缩后编译源码。

$ wget http://download.redis.io/releases/redis-2.8.3.tar.gz

$ tar xzf redis-2.8.3.tar.gz

$ cd redis-2.8.3

$ make

修改redis.conf，打开后台运行选项：

# By default Redis does not run as a daemon. Use 'yes' if you need it.
# Note that Redis will write a pid file in /var/run/redis.pid when daemonized.
daemonize yes

编写脚本，vim /etc/init.d/redis:

##!/bin/bash

# chkconfig: 2345 10 90
# description: Start and Stop redis
 
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
 
REDISPORT=6379 #实际环境而定
EXEC=/usr/local/redis/src/redis-server #实际环境而定
REDIS_CLI=/usr/local/redis/src/redis-cli #实际环境而定
 
PIDFILE=/var/run/redis.pid
CONF="/usr/local/redis/redis.conf" #实际环境而定
 
case "$1" in
        start)
                if [ -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is already running or crashed."
                else
                        echo "Starting Redis server..."
                        $EXEC $CONF
                fi
                if [ "$?"="0" ]
                then
                        echo "Redis is running..."
                fi
                ;;
        stop)
                if [ ! -f $PIDFILE ]
                then
                        echo "$PIDFILE exists, process is not running."
                else
                        PID=$(cat $PIDFILE)
                        echo "Stopping..."
                        $REDIS_CLI -p $REDISPORT SHUTDOWN
                        while [ -x $PIDFILE ]
                        do
                                echo "Waiting for Redis to shutdown..."
                                sleep 1
                        done
                        echo "Redis stopped"
                fi
                ;;
        restart|force-reload)
                ${0} stop
                ${0} start
                ;;
        *)
                echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2
                exit 1
esac

设置执行权限：

chmod +x /etc/init.d/redis

开机自动启动设置：

# 尝试启动或停止redis
service redis start
service redis stop

# 开启服务自启动
chkconfig redis on
