redist启动脚本

Redis启动脚本是一个用于启动Redis服务器的脚本。它通常由Redis安装程序提供，可以在Linux系统中找到该脚本。Redis启动脚本可以让我们方便地管理Redis服务器的启动、停止和重启等操作。

在Linux系统中，Redis启动脚本的路径通常为/etc/init.d/redis，它包含了一些常用的命令，例如start、stop和restart等。使用这些命令可以方便地启动、停止和重启Redis服务器。

下面是一个简单的Redis启动脚本示例：

#!/bin/bash
# redis - this script starts and stops the redis- 85 15
# description:  Redis is a persistent key-value database
# processname: redis-server
# config:      /etc/redis/redis.conf
# pidfile:     /var/run/redis.pid

REDISPORT=6379
EXEC=/usr/bin/redis-server
CLIEXEC=/usr/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 Redis server..."
            $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"
        ;;
