Redis三种启动方式

1. 直接启动

进入redis根目录，执行命令：

./redis-server 

2. 通过指定配置文件启动

可以为redis服务启动指定配置文件；如配置为/etc/redis/redis.conf

进入redis 根目录，输入命令：

./redis-server /etc/redis/redis.conf

如果更改了端口，使用“redis-cli”客户端连接时，也需要指定端口 例如：

./redis-cli -p 6378

3. 使用redis启动脚本设置开机启动

启动脚本redis_init_script位于 /redis安装目录/util/下。redis_init_script代码如下

#!/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

    
    

​ 根据启动脚本，用root用户进行一下操作：

​

mkdir /etc/redis
cp redis.conf /etc/redis/6379.conf

将启动脚本copy到/etc/init.d目录下，本例将启动脚本命名为redisd(通常都以d结尾表示是后台自启动服务)。

./copy /opt/redis/util /etc/init.d/redisd

设置开机启动

#设置为开机自启动服务器
chkconfig redisd on
#打开服务
service redisd start
#关闭服务
service redisd stop
