一、salt-ssh

1、salt-ssh安裝

2、配置文件

參考：https://docs.saltstack.com/en/latest/topics/ssh/index.html

cd /etc/salt/

[root@salt salt]# vi roster 

# Sample salt-ssh config file
#web1:
#  host: 192.168.42.1 # The IP addr or DNS hostname
#  user: fred         # Remote executions will be executed as user fred
#  passwd: foobarbaz  # The password to use for login, if omitted, keys are used
#  sudo: True         # Whether to sudo to root, not enabled by default
#web2:
#  host: 192.168.42.2
linux-node1:
  host: 192.168.56.42
  user: root
  passwd: 1qaz@WSX
  prod: 22

 測試，參數 -i ，如果詢問密碼就加-i,直接幫你確認，-i = yes

[root@salt salt]# salt-ssh '*' test.ping
linux-node1:
    True

#確認yes
[root@salt salt]# salt-ssh '*' test.ping -i 
linux-node1:
    True

#配置不提示你輸入yes

[root@salt .ssh]# pwd
/root/.ssh
[root@salt .ssh]# ll
total 16
-rw-r--r-- 1 root root   25 Jun 24 11:22 config
-rw------- 1 root root 1675 Jun 24 06:37 id_rsa
-rw-r--r-- 1 root root  391 Jun 24 06:37 id_rsa.pub
-rw-r--r-- 1 root root  187 Jun 24 06:39 known_hosts

#寫入下面配置文件和參數，就不會提示你輸入yes，進行確認。
[root@salt .ssh]# cat config
