摘要：
原因：redhat自带的插件subscription-manager。
系统：redhat 7.6
说明：配置yum源，提示This system is not registered with an entitlement server. You can use subscription-manager to register.
配置文件：
[root@localhost yum.repos.d]# cat redhat7.repo [rhel-source] name=Source baseurl=file:///mnt enabled=1gpgcheck=0
yum安装测试，能够进行安装，但是系统提示没有注册
[root@localhost yum.repos.d]# yum install -y tree Loaded plugins: product-id, search-disabled-repos, subscription-manager 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
[root@localhost yum.repos.d]# vi /etc/yum/pluginconf.d/subscription-manager.conf [main] #enabled=1 ~
将安装的软件remove，再次进行安装实验
