Centos yum命令用不了

一般报错为：This system is not registered with an entitlement server. You can use subscription-manager to register.

原因：redhat自带的插件subscription-manager。这个插件的作用就是Red Hat Subscription Manager订阅管理器，就是它让你一直register

解决办法：将配置文件subscription-manager.conf中的enable注释掉

vi /etc/yum/pluginconf.d/subscription-manager.conf

[main]
#enabled=1
~
