Redis脚本启动问题

因软件包自带的有脚本，我用的是4.0.10的源码包，修改即可

[[email protected] redis-4.0.10]# find / -name redis_init_script

/usr/local/redis-4.0.10/utils/redis_init_script

[[email protected] redis-4.0.10]# cp /usr/local/redis-4.0.10/utils/redis_init_script /etc/init.d/redisd

[[email protected] redis-4.0.10]#cat /etc/init.d/redisd

#!/bin/sh

#

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

# as it does use of the /proc filesystem.

### BEGIN INIT INFO

# Provides:     redis_6379

# Default-Start:        2 3 4 5

# Default-Stop:         0 1 6

# Short-Description:    Redis data structure server

# Description:          Redis data structure server. See https://redis.io

### END INIT INFO

REDISPORT=6379

EXEC=/usr/local/bin/redis-server

CLIEXEC=/usr/local/bin/redis-cli

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

CONF="/etc/redis/${REDISPORT}.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

我的端口是6380 ，安装目录在/usr/local/redis-4.0.10 ，所以REDISPORT=6380 ，EXEC=/usr/local/redis-4.0.10/src/redis-server ，CLIEXEC=/usr/local/redis-4.0.10/src/redis-cli ，CONF="/usr/local/redis-4.0.10/redis.conf"

给与执行权限后停止报错

[[email protected] redis-4.0.10]# /etc/init.d/redisd stop

^C

此时检查进程还在，既然是提示验证出错，那就检查脚本

$CLIEXEC -a "password" -p $REDISPORT shutdown  

添加红色内容，password是用redis-cli客户端登陆 -a后面跟的密码

[[email protected] redis-4.0.10]# /etc/init.d/redisd stop

Stopping ...

OK已成功停止Redis
