# [redis设置开机启动 ][redis_] #

方式一

1.设置redis.conf中daemonize为yes,确保守护进程开启,也就是在后台可以运行.(设置为yes后,启动时好像没有redis的启动界面,不知道为什么)

#vi编辑redis安装目录里面的redis.conf文件
    [root@localhost /]# vi /usr/redis/redis-3.2.4/redis.conf

2.复制redis配置文件(启动脚本需要用到配置文件内容,所以要复制)

#1.在/etc下新建redis文件夹
    [root@localhost /]# mkdir /etc/redis
    #2.把安装redis目录里面的redis.conf文件复制到/etc/redis/6379.conf里面,6379.conf是取的文件名称,启动脚本里面的变量会读取这个名称,所以要是redis的端口号改了,这里也要修改
    [root@localhost redis]# cp /usr/redis/redis-3.2.4/redis.conf /etc/redis/6379.conf

3.复制redis启动脚本

#1.redis启动脚本一般在redis根目录的utils,如果不知道路径,可以先查看路径
    [root@localhost redis]# find / -name redis_init_script
    /usr/redis/redis-3.2.4/utils/redis_init_script
    #2.复制启动脚本到/etc/init.d/redis文件中
    [root@localhost redis]# cp /usr/redis/redis-3.2.4//utils/redis_init_script /etc/init.d/redis

4.修改启动脚本参数

[root@localhost redis]# vi /etc/init.d/redis
    #在/etc/init.d/redis文件的头部添加下面两行注释代码,也就是在文件中#!/bin/sh的下方添加
    # chkconfig: 2345 10 90  
    # description: Start and Stop redis

如图

同时还要修改参数,指定redis的安装路径

修改完成后按 Esc ,再按 :wq + Enter(回车) 保存并退出

5.启动redis

打开redis命令:service redis start

关闭redis命令:service redis stop

设为开机启动:chkconfig redis on

设为开机关闭:chkconfig redis off

方式二

1.编写脚本

[root@localhost ~]# vi /etc/init.d/redis

复制下面代码到脚本中(注意要修改里面redis的安装路径,以/usr/redis/redis-3.2.4路径为例)(这段代码就是redis根目录 /utils/redis\_init\_script 启动脚本的代码)

#!/bin/sh
    # chkconfig: 2345 10 90  
    # description: Start and Stop redis   
    
    REDISPORT=6379
    EXEC=/usr/redis/redis-3.2.4/src/redis-server
    CLIEXEC=/usr/redis/redis-3.2.4/src/redis-cli
    
    PIDFILE=/var/run/redis_${REDISPORT}.pid
    CONF="/usr/redis/redis-3.2.4/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
            ;;
        restart)
            "$0" stop
            sleep 3
            "$0" start
            ;;
        *)
            echo "Please use start or stop or restart as first argument"
            ;;
    esac

3.保存退出,设置权限

[root@localhost ~]# chmod 777 /etc/init.d/redis

4.启动redis

[root@localhost ~]# service redis start
