1-环境准备

1-1下载redis-4.0.11.tar.gz

可从以下路径下载：http://download.redis.io/releases/redis-4.0.11.tar.gz

1-2gcc环境

有网络连接的情况下可通过 yum install gcc来安装最新版本

2-上传解压

进入/usr/local/redis目录下，解压redis安装文件

cd /usr/local/redis
tar ‐xzvf redis‐4.0.11.tar.gz

3-编译安装(需要gcc环境)

cd /usr/local/redis/redis‐4.0.11 
make

4-配置redis

在/usr/local/redis/redis‐4.0.11目录下编辑配置文件（允许外网访问）

vi redis.conf

在bind 127.0.0.1前加“#”将其注释掉
默认为保护模式，把 protected‐mode yes 改为 protected‐mode no
默认为不守护进程模式，把daemonize no 改为daemonize yes
将 requirepass foobared前的“#”去掉，修改密码为123456（我为了练习用）
将pidfile修改为/usr/local/redis/redis-4.0.11/redis_6379.pid（参照redis.sh）

5-启动Redis

cd /usr/local/redis/redis‐4.0.11/ 
./src/redis‐server redis.conf

6-开启防火墙(root)

#开启防火墙的某个端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent
#重载防火墙
firewall-cmd --reload

7-添加开机启动脚本

编写启动脚本redis.sh ，加入如下内容：

#!/bin/sh
# chkconfig: 2345 80 90
# description: Start and Stop redis
#PATH=/usr/local/bin:/sbin:/usr/bin:/bin
REDISPORT=6379
EXEC=/usr/local/redis/redis-4.0.11/src/redis-server
REDIS_CLI=/usr/local/redis/redis-4.0.11/src/redis-cli
PIDFILE=/usr/local/redis/redis-4.0.11/redis_6379.pid
CONF=/usr/local/redis/redis-4.0.11/redis.conf
AUTH="123456"

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

8-设置权限

chmod 777 /usr/local/redis/redis.sh

9-设置开机启动

cp redis.sh /etc/init.d/redis 
chkconfig ‐‐add redis  
chkconfig redis on

10-测试redis服务

service redis start 
service redis stop

11-检查是否安装成功

ps ‐ef | grep redis

12-创建redis命令软连接

ln ‐s /usr/local/redis/redis‐4.0.11/src/redis‐cli /usr/bin/redis

13-测试redis

14-必要时设置防火墙

vi /etc/sysconfig/iptables 添加如下内容
‐A INPUT ‐p tcp ‐m state ‐‐state NEW ‐m tcp ‐‐dport 6379 ‐j ACCEPT

启动指令:service iptables start 
重启指令:service iptables restart 
关闭指令:service iptables stop
