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!
