内容二:gzip 命令的使用案例

2.1 案例一:压缩文件

[排错] RHEL 解决使用 yum 命令时卡住

报错代码

# yum update 
Updating Subscription Management repositories.
Unable to read consumer identity

可尝试的解决方法一:修改 /etc/yum/pluginconf.d/subscription-manager.conf 文件

# vim /etc/yum/pluginconf.d/subscription-manager.conf

将以下内容:

......
[main] 
enabled=1
......

修改为:

......
[main] 
enabled=0
......

可尝试的解决方法二:安装对应的 katello-ca-consumer-latest.noarch.rpm 软件包

(步骤略)

(补充:katello-ca-consumer-latest.noarch.rpm 软件包下载自对应的 Red Hat Satellite 服务器,补充链接:Red Hat Satellite client register
