今天筆者在公司redhat 6.x/7.x服務器上使用yum命令報如下錯誤：
[root@qq_5201351 ~]# yum list Loaded plugins: product-id, refresh-packagekit, search-disabled-repos, security, subscription-manager https://cdn.redhat.com/content/dist/rhel/server/6/6Server/x86_64/os/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 403 Forbidden" Trying other mirror. To address this issue please refer to the below knowledge base article https://access.redhat.com/solutions/69319 If above article doesn't help to resolve this issue please open a ticket with Red Hat Support. Error: Cannot retrieve repository metadata (repomd.xml) for repository: rhel-6-server-rpms. Please verify its path and try again
為了排錯，筆者只留下了一個redhat.repo(這個文件移動走了，默認也會自動生成)，還是報如上錯誤
對於這個403錯誤，筆者剛開始在思考是不是/etc/yum.conf配置中的代理服務器返回的，於是在自己電腦上訪問上面的url也是403錯誤
后又想了下，代理服務器應該也不會干這樣的事，應該更可能還是服務器自身的問題，
對於yum，紅帽系統是使用到了訂閱這個概念的，於是檢查，license及訂閱信息，結果如下：
[root@qq_5201351 ~]# subscription-manager list +-------------------------------------------+ Installed Product Status +-------------------------------------------+ Product Name: Red Hat Enterprise Linux Server Product ID: 69 Version: 6.10 Arch: x86_64 Status: Subscribed Status Details: Starts: 05/30/2020 Ends: 05/30/2021
看着也沒有問題啊，最后反復看到上面的報錯信息，猛然發現了有個鏈接，https://access.redhat.com/solutions/69319
不過好像需要訂閱了的才能看到詳情，解決方案的大體意思是要重新注冊訂閱，於是重新注冊后，問題得到解決！
If an still issue persists, then unregister the system and register again using the following commands: # subscription-manager unregister # subscription-manager clean # subscription-manager register Subscribe the system with the required subscription(s) or use auto subscribe option to automatically assign subscription to the system. # subscription-manager attach --auto Clean yum cache and try running yum command to confirm whether yum works or not. # yum clean all # yum repolist If there is Proxy server required to connect to the internet then configure the proxy server. In /etc/yum.conf please add the proxy details as stated in the article : e.g. proxy=http://mycache.mydomain.com:3128 # The account details for yum connections proxy_username=proxy-user proxy_password=password.
