CenterOS 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/

    if [ "$?"="0" ] 
    then
       echo "Redis is running..."
    fi
    ;;

    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

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
