Linux下Screen的常用命令

向您推荐以下文章，已经将链接贴出来啦。Linux 技巧：使用 screen 管理你的远程会话

详细资料参考以上链接，最下面是本人的一些实际操作，仅供参考：

已经将个人示例的系统版本和YUM库的配置列出来了

1、新建screen会话：直接输入screen命令或者screen -S [会话名称]

2、退出会话：按下组合键Ctrl+a并松开，此时screen窗口等待命令，然后按下d并松开，退出screen窗口。

3、查看当前系统所有screen会话：screen -ls

4、进入某个screen会话：screen -r [会话的PID]

5、在进入某个screen会话后，杀死screen会话：按下组合键Ctrl+a并松开，此时screen窗口等待命令，然后按下大写的K（即组合键：Shift+k）并松开，（系统提示是否要杀死）按下y确认杀死screen会话。

总结：当系统中只有一个screen会话时，输入：screen -r 即可进入这个会话，

当系统中有多个screen会话时，此时输入同样的命令，系统会列出当前所有screen回话，相当于命令：screen -ls

更多的关于screen的参数，可以参考手册：man screen

同时还要多多实际操作，会得到更多的切身体会，希望本文能够对感兴趣的读者有所帮助，欢迎转载，很愿意分享分享，共同成长，谢谢！

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# 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
# remarked out baseurl= line instead.
