## 源码安装

1.安装tcl支持

yum install tcl

2.安装redis我们以最新的2.8.9为例

$ wget http://download.redis.io/releases/redis-3.2.8.tar.gz
$ tar xzf redis-3.2.8.tar.gz
$ cd redis-3.2.8
$ make
$ make test
$ make install

测试通过后安装，安装后会自动把redis-server,redis-cli,redis-benchmark,redis-check-aof,redis-check-dump复制到/usr/local/bin目录下。

## yum 安装

$ yum -y install redis

// 如果yum提示没有redis，则先安装 epel源，在重新安装
$ yum install epel-release

编辑redis.conf文件

vi redis.conf

修改daemonize no改成yes。

我们手动复制redis.conf到/etc目录下

cp redis.conf /etc

编写自init.d脚本。

内容如下：

                $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

可以通过winscp上传到/etc/init.d/目录下

修改权限，可以运行

chmod +x /etc/init.d/redis

设置开机自动启动服务

sudo chkconfig redis on

启动服务：

service redis start

停止服务：

service redis stop

配置防火墙打开对应的端口：

vi /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT

重启防火墙

service iptables restart
