redis已经加入到etc下也就是服务器启动redis 也启动。突然发现连不上redis 所以上来看看
查看redis 状态：systemctl status redis
● - redis-server
Loaded: loaded (/usr/lib/systemd/system/; disabled; vendor preset: disabled)
Active: inactive (dead)
发现没启动
启动后再看看状态：systemctl start redis
[root@VM_0_2_centos /]# systemctl status redis
● - redis-server
Loaded: loaded (/usr/lib/systemd/system/; disabled; vendor preset: disabled)
Active: active (running) since Thu 2019-03-21 08:58:08 CST; 5s ago
Process: 26556 ExecStart=/usr/local/bin/redis-server /usr/local/yangsx/redis/redis-3.0.0/ (code=exited, status=0/SUCCESS)
Main PID: 26557 (redis-server)
CGroup: //

重启redis：systemctl restart 或者service redis restart
