1.2.1在master設置規則容許特定用戶，可以使用的特定方法

1. [root@linux-node1 salt]# vim /etc/salt/master

245 client_acl:

246   zhurui1:

247     - test.ping

248     - network.

[root@linux-node1 salt]# /etc/init.d/salt-master restart

Stopping salt-master daemon:                               [  OK  ]

Starting salt-master daemon:                                 [  OK  ]

[root@linux-node1 salt]# useradd  zhurui1  ##建立用戶，而且設置密碼

[root@linux-node1 salt]# echo '123456'|passwd --stdin zhurui1

Changing password for user zhurui.

passwd: all authentication tokens updated successfully.

[root@linux-node1 salt]# 

[root@linux-node1 home]# chmod 777 /var/log/salt/master

[root@linux-node1 home]# su - zhurui1

[zhurui1@linux-node1 ~]$ salt '*' test.ping

linux-node2.zhurui.com:

    True

linux-node1.zhurui.com:

    True

[zhurui1@linux-node1 ~]$

1.2.2 指定特定主機，在特定用戶下容許的操做

1. client_acl:
2. zhurui1:
3. - test.ping
4. - network.*
5. user01:
6. - linux-node1*:
7. - test.ping

[root@linux-node1 home]# /etc/init.d/salt-master restart

Stopping salt-master daemon:                               [  OK  ]

Starting salt-master daemon:                               [  OK  ]

[root@linux-node1 home]# su - user01

[user01@linux-node1 ~]$ salt '*' test.ping           

Failed to authenticate! This is most likely because this user is not permitted to execute commands, but there is a small possibility that a disk error occurred (check disk/inode usage).

[user01@linux-node1 ~]$ salt 'linux-node1*' test.ping 

linux-node1.zhurui.com:

    True

1.2.3 指定黑名單，禁止特定用戶的操做
