=======================================================================================================

 环境配置

角色	主机名	IP	组名
master	master.salt.com	192.168.200.100
minion	node1.salt.com	192.168.200.101	web1group
minion	node2.salt.com	192.168.200.102	web2group

安装EPEL三台都安装EPEL

[root@master ~]# ls
epel-release-latest-7.noarch.rpm
[root@master ~]# rpm -ivh epel-release-latest-7.noarch.rpm
警告：epel-release-latest-7.noarch.rpm: 头V3 RSA/SHA256 Signature, 密钥 ID 352c64e5: NOKEY

安装Saltstack三台都安装

[root@master ~]# yum install salt-master -y              #主控端

[root@node1 ~]# yum install salt-minion -y                #被控端

[root@node2 ~]# yum install salt-minion -y                #被控端

修改映射关系

[root@master ~]# vim /etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.200.100 master.salt.com
192.168.200.101 node1.salt.com
192.168.200.102 node2.salt.com

将hosts文件发送给node1和node2两台被控主机

[root@master ~]# scp /etc/hosts 192.168.200.101:/etc/

[root@master ~]# scp /etc/hosts 192.168.200.102:/etc/

[root@master ~]# vim /etc/salt/master

    interface: 192.168.200.100          #绑定master通信IP
   auto_accept: True                   #自动认证，避免手动运行salt-key来确认证书信任
   file_roots:                         #指定saltstack文件根目录位置
     base:
       - /srv/salt/

[root@master ~]# systemctl start salt-master

node1与node2被控端主机都执行本次操作

[root@node1 ~]# vim /etc/salt/minion

      master: 192.168.200.100       #指定master主机IP地址
      id: node1.salt.com             #修改被控主机识别ID，建议使用操作系统

[root@node1 ~]# systemctl start salt-minion

[root@master ~]# salt '*' test.ping                
node2.salt.com:
True
node1.salt.com:
True

[root@master salt]# salt-key -L
Accepted Keys:
node1.salt.com
