1、master安裝及配置
yum install salt-master -y
在master上修改配置文件（/etc/salt/master）
找到以下內容，註釋全部去掉，並且注意下面base前面和下一行前面的空格數量，一個爲2，一個爲4
# vim /etc/salt/master
file_roots:
base:
- /srv/salt
pillar_roots:
base:
- /srv/pillar
啓動master的salt-master
root@ubuntu16:/etc/salt# /etc/init.d/salt-master start
[ ok ] Starting salt-master (via systemctl): salt-master.service.
2、在minion上安裝salt-minion
yum install salt-minion -y
修改minion的配置文件（/etc/salt/minion）
#在大概16行的master上添加master主機ip地址或主機名（需要地址解析），冒號和ip之間有一空格
# vim /etc/salt/minion
master: 192.168.99.99
# 找到#id，把註釋去掉，給每一臺虛擬機起一個有意義的id名稱
# 這裏三臺minion都取各自類型的名稱，如果此項不修改，則會使用每臺虛擬機的主機名
id: hostname1
id: hostname2
id: hostname3
3、啓動salt-master服務失敗：
root@ubuntu16:/etc/salt# /etc/init.d/salt-master start
[....] Starting salt-master (via systemctl): salt-master.serviceJob for salt-master.service failed because the control process exited with error code. See "systemctl status salt-master.service" and "journalctl -xe" for details.
failed!
執行 systemctl status salt-master 查看問題
root@ubuntu16:/etc/salt# systemctl status salt-master
