解决办法：

打开redis的配置文件，如/etc/codis/codis-server/redis7021.conf

#?bind?127.0.0.1?
protected-mode?no??#?保护模式

杀死原本的redis进程

>>>?ps?-ef?|?grep?codis??#?查看codis运行的进程

root?????13695?????1??0?11:47??????????00:00:05?codis-server?*:7021
root?????13700?????1??0?11:47??????????00:00:05?codis-server?*:7022
root?????13719?26723??0?11:55?pts/21???00:00:07?codis-proxy?--ncpu=1?--config=/etc/codis/codis-proxy/proxy.toml?--log=/usr/local/codis/logs/proxy.log?--log-level=warn

>>>?kill?-9?13695
>>>?kill?-9?13700

开启codis-server

codis-server?/etc/codis/codis-server/redis7021.conf?
codis-server?/etc/codis/codis-server/redis7022.conf
