【安装Redis】CentOS7 下安装NodeJs+Express+MongoDB+Redis

Redis，V3.2，官网l官方链接:http://www.redis.io/download，参考:http://blog.csdn.net/mlks_2008/article/details/19001595

1、安装Redis

wget http://download.redis.io/releases/redis-3.2.1.tar.gz
tar xzf redis-3.2.1.tar.gz
cd redis-3.2.1
make

2、设置Redis为开机启动

• redis的命令会被拷贝到/usr/local/bin下面

　　cp redis.conf /etc/

• 创建redis脚本执行文件：vi /etc/init.d/redis

　　脚本内容如下：

# chkconfig: 2345 10 90 
# description: Start and Stop redis 
PATH=/usr/local/bin:/sbin:/usr/bin:/bin
   
REDISPORT=6379
EXEC=/usr/local/bin/redis-server
REDIS_CLI=/usr/local/bin/redis-cli
   
PIDFILE=/var/run/redis.pid
CONF="/etc/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 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

• 然后设置此文件的属性

        chmod +x /etc/init.d/redis

•     修改daemonize no 改为 daemonize yes

            vim /etc/redis.conf

• 　　设置开机启动服务

           chkconfig redis on  

3、常用命令

启动服务：

/etc/init.d/redis start  

停止服务：

 /etc/init.d/redis stop 

测试命令：

redis-cli
   
redis 127.0.0.1:6379> set foo 123  

redis 127.0.0.1:6379> get foo  

redis 127.0.0.1:6379> exit
