linux设置redis开机启动

linux设置开机启动两个步骤：

1. 设置redis.conf中daemonize为yes,确保守护进程开启。
2. 编写开机自启动脚本

基本原理为：

系统开机启动时会去加载/etc/init.d/下面的脚本，通常而言每个脚本文件会自定义实现程序的启动；若想将新的程序开机自启动，只需在该目录下添加一个自定义启动程序的脚本，然后设置相应规则即可。

如在这里我们在/etc/init.d/下新建一个 redis 的脚本，开机启动时会去加载执行该脚本。

vim /etc/init.d/redis
           

脚本内容如下:

#!/bin/sh

# chkconfig:   2345 90 10

# description:  Redis is a persistent key-value database

# Simple Redis init.d script conceived to work on Linux systems  

# as it does use of the /proc filesystem.  

REDISPORT=6379

REDISROOT=/usr/local/redis/redis-5.0.5/

REDISPATH=/usr/local/redis/redis-5.0.5/src/

EXEC=${REDISPATH}/redis-server

CLIEXEC=${REDISPATH}/redis-cli

PIDFILE=/var/run/redis_${REDISPORT}.pid

CONF="${REDISROOT}/redis.conf"

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

    ;;

  stop)

    if [ ! -f $PIDFILE ]

    then

        echo "$PIDFILE does not exist, process is not running"  

    else

        PID=$(cat $PIDFILE)

        echo "Stopping ..."  

        $CLIEXEC -p $REDISPORT shutdown

        while [ -x /proc/${PID} ]  

        do

          echo "Waiting for Redis to shutdown ..."  

          sleep 1

        done

        echo "Redis stopped"  

    fi

    ;;

  *)

    echo "Please use start or stop as first argument"  

    ;;

esac

写完后保存退出

设置可执行权限：

chmod 777 /etc/init.d/redis
           

启动redis:

/etc/init.d/redis start
           

执行结束之后用redis-cli 或者 ps aux|grep redis 查看redis是否成功启动.

设置开机启动:

chkconfig redis on
           

关机重启测试:

reboot
           

重启之后再次验证改动是否生效!
