redis设置开机自启动会不会用root用户启动

可以使用root用户启动redis开机自启动。您可以使用以下命令将redis添加到系统启动项中：

1. 编辑redis的启动脚本：sudo vi /etc/init.d/redis
2. 在脚本中添加以下内容：

#!/bin/sh
# chkconfig: 2345 90 10
# description: Redis is a persistent key-value database

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

3. 保存并退出文件
4. 添加执行权限：sudo chmod +x /etc/init.d/redis
5. 将redis添加到系统启动项中：sudo update-rc.d redis defaults
6. 启动redis：sudo service redis start

这样，redis就会在系统启动时自动启动。
