Linux下设置redis使用service服务启动

Posted 2021-12-13 moying-wq

方法一:

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

#vi编辑redis安装目录里面的redis.conf文件
[[email protected] /]# vi /usr/redis/redis-3.2.4/redis.con 

 

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
[[email protected] /]# 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
[[email protected] 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
[[email protected] 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
[[email protected] 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

[[email protected] 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

修改完成后的截图

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

 

[[email protected] ~]# 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

 

[[email protected] ~]# chmod 777 /etc/init.d/redis

 

4.启动redis

 

[[email protected] ~]# service redis start

 

 

5. 重启
