向您推薦以下文章，已經將鏈接貼出來啦。Linux 技巧：使用 screen 管理你的遠程會話 http://www.linuxidc.com/Linux/2011-02/32178.htm
詳細資料參考以上鏈接，最下面是本人的一些實際操作，僅供參考：
已經將個人示例的系統版本和YUM庫的配置列出來了
1、新建screen會話：直接輸入screen命令或者screen -S [會話名稱]
2、退出會話：按下組合鍵Ctrl+a並松開，此時screen窗口等待命令，然後按下d並松開，退出screen窗口。
3、查看當前系統所有screen會話：screen -ls
4、進入某個screen會話：screen -r [會話的PID]
5、在進入某個screen會話後，殺死screen會話：按下組合鍵Ctrl+a並松開，此時screen窗口等待命令，然後按下大寫的K（即組合鍵：Shift+k）並松開，（系統提示是否要殺死）按下y確認殺死screen會話。
總結：當系統中只有一個screen會話時，輸入：screen -r 即可進入這個會話，
當系統中有多個screen會話時，此時輸入同樣的命令，系統會列出當前所有screen回話，相當於命令：screen -ls
更多的關於screen的參數，可以參考手冊：man screen
同時還要多多實際操作，會得到更多的切身體會，希望本文能夠對感興趣的讀者有所幫助，歡迎轉載，很願意分享分享，共同成長，謝謝！

# The mirror system uses the connecting IP address of the client and the

# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.

# If the mirrorlist= does not work for you, as a fall back you can try the
