CentOS 中安装Redis及开机启动设置详解

从官方下载最新Redis进行安装，官网地址：http://redis.io/download

				?

									$ wget http://download.redis.io/releases/redis-3.2.3.tar.gz

									$ tar xzf redis-3.2.3.tar.gz

									$ cd redis-3.2.3

									$ make

									$ make install

Redis启动

RedisServer /path/to/redis.conf

Redis关闭(默认port为6379)

RedisCli -p port -a Password shutdown

查看Reids进程

ps -ef|grep redis

设置Redis开机启动

1：配置init脚本，把代码存为Reids，放到/etc/init.d/

				?

									###########################

									# chkconfig:  2345 90 10

									# description: Redis is a persistent key-value database

									PATH=/usr/local/bin

									REDISPORT=6379

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

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

									#Redis密码

									PASSWORD=yourPassword

									PIDFILE=/var/run/redis.pid

									CONF="/usr/local/reids/conf/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

									    if [ "$?"="0" ] 

									    then

									       echo "Redis is running..."

									    fi

									    ;;

									  stop)

									    if [ ! -f $PIDFILE ]

									    then

									        echo "$PIDFILE does not exist, process is not running"

									    else

									        PID=$(cat $PIDFILE)

									        echo "Stopping ..."

									        $REDIS_CLI -p $REDISPORT -a $PASSWORD SHUTDOWN

									        while [ -x ${PIDFILE} ]

									        do

									          echo "Waiting for Redis to shutdown ..."

									          sleep 1

									        done

									        echo "Redis stopped"

									    fi

									    ;;

									  restart|force-reload)

									    ${0} stop

									    ${0} start

									    ;;

									 *)

									  echo "Usage: /etc/init.d/redis {start|stop|restart|force-reload}" >&2

									    exit 1

									esac

									##############################

注意事项:

　　1) 最上面的注释的意思是，redis服务必须在运行级2，3，4，5下被启动或关闭，启动的优先级是90，关闭的优先级是10。　　　　

　　2) 如果执行命令出现$'/r':command not found，这个问题是在Windows下换行和linux下换行不同，可以通过Nodepad++进行转换。

2：设置脚本权限

				?

									chmod +x /etc/init.d/redis

3：设置开机启动

				?

									sudo chkconfig redis on

4：使用方法

				?

									service redis start  #或者 /etc/init.d/redis start

									service redis stop  #或者 /etc/init.d/redis stop
