SSH 互信

A：master

B：server

在A B机器 当前用户的绝对目录 进行创建 .ssh 

# mkdir ~/.ssh
# chmod 700 .ssh/
# /usr/bin/ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
41:21:31:03:97:5b:b2:c6:32:07:98:a5:4c:7d:28:c1 root@10-205-203-191
The key's randomart image is:
+--[ RSA 2048]----+
| .o*oo*oo. |
| oE.+.+=. |
| o. + =. |
| o * . |
| = S |

# cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
# chmod 600 ~/.ssh/authorized_keys

拷贝 master 远程机器的 authorized_keys；粘贴到被远程的server 机器上； 然后直接远程就可以了

2、可以设置一个脚本进行执行；

然后把堡垒机的auth 拷贝到服务的机器上；

# cat in.sh

# cat in.sh

mkdir ~/.ssh
chmod 700 .ssh/
/usr/bin/ssh-keygen -t rsa
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
