安裝redis

步驟一：安裝最新的redis，需要安裝Remi的軟體源，官網地址：http://rpms.famillecollet.com.

yum install -y http://rpms.famillecollet.com/enterprise/remi-release-7.rpm

步驟二：安裝redis(預設安裝最新版本)

yum --enablerepo=remi install -y  redis

步驟三：啟動redis

[root@localhost ~]# systemctl start redis
[root@localhost ~]# systemctl status redis

步驟四：檢視redis版本號

[root@server01 ~]# redis-cli --version
redis-cli 6.0.6

systemctl enable redis.service

預設yum安裝之後，redis的配置檔案在/etc/redis.conf
    vim redis.conf
              daemonize yes  //222行
127.0.0.1  192.168.11.100  //69
