SaltStack之salt-ssh
文章目录
salt-ssh介绍
salt-ssh可以让我们不需要在受控机上安装salt-minion客户端也能够实现管理操作。
salt-ssh的特点
- 远程系统需要Python支持，除非使用-r选项发送原始ssh命令
- salt-ssh是一个软件包，需安装之后才能使用，命令本身也是salt-ssh
- salt-ssh不会取代标准的Salt通信系统，它只是提供了一个基于SSH的替代方案，不需要ZeroMQ和agent
请注意，由于所有与Salt SSH的通信都是通过SSH执行的，因此它比使用ZeroMQ的标准Salt慢得多
salt-ssh远程管理的方式
salt-ssh有两种方式实现远程管理，一种是在配置文件中记录所有客户端的信息，诸如 IP 地址、端口号、用户名、密码以及是否支持sudo等；另一种是使用密钥实现远程管理，不需要输入密码。
salt-ssh管理
在 master 上安装 salt-ssh
[root@master ~]# yum -y install salt-ssh
通过使用用户名密码的SSH实现远程管理
修改配置文件，添加受控机信息
[root@master ~]# vim /etc/salt/roster
vm1:
host: 192.168.207.131
user: root
port: 22
passwd: 789123
vm2:
host: 192.168.207.137
user: root
port: 22
passwd: 789123
vm3:
host: 192.168.207.136
user: root
port: 22
passwd: 789123
测试连通性
[root@master ~]# vim ~/.ssh/config
StrictHostKeyChecking no
[root@master ~]# salt-ssh '*' test.ping
vm1:
True
从上面的信息可以看出，第一次访问时需要输入 yes/no ，但是 saltstack 是不支持交互式操作的，所以为了解决这个问题，我们需要对其进行设置，让系统不进行主机验证。
[root@master ~]# vim ~/.ssh/config
StrictHostKeyChecking no
[root@master ~]# salt-ssh '*' test.ping
vm2:
True
vm1:
True
vm3:
True
把所有的被控主机安装python3
[root@master ~]# salt-ssh '*' -r 'yum install -y python3'
