# 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.

Windows vscode记住ssh密码
win生成公钥、私钥:

ssh-keygen -t rsa -C "x@qq.com"

linux:将win下的id_rsa.pub（公钥内容）复制到Linux下的authorized_keys文件

[root@node2 .ssh]# pwd
/root/.ssh
[root@node2 .ssh]# ll
total 16
-rw-r--r--. 1 root root  399 Feb 23 07:43 authorized_keys
