SaltStack进阶之salt-syndic分布式架构

 
 
 

1. salt-syndic分布式架构

 

1.1 salt-syndic架构图

 
 
 

1.2 salt-syndic的优劣势

优势：

• 可以通过syndic实现更复杂的salt架构
• 减轻master的负担

 
劣势：

• syndic的/srv目录下的salt和pillar目录内容要与最顶层的master下的一致，所以要进行数据同步，同步方案同salt-master高可用
• 最顶层的master不知道自己有几个syndic，它只知道自己有多少个minion，并不知道这些minion是由哪些syndic来管理的
   
   

2. salt-syndic部署

主机	IP	安装的应用
master	192.168.30.150/24	salt-master
syndic	192.168.30.244/24	salt-master salt-syndic
minion	192.168.30.245/24	salt-minion

 
 

2.1 在syndic上安装salt-syndic

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

 
 

2.2 修改master配置文件

//取消order_masters注释，并将值给为True

[root@master ~]# vim /etc/salt/master
......
order_masters: True     ##改为True


[root@master ~]# systemctl restart salt-master
[root@master ~]# systemctl enable salt-master

 
 

2.3 修改syndic配置文件

//取消syndic_master注释.并改成master端IP

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

[root@syndic ~]# vim /etc/salt/master
......
syndic_master: 192.168.30.150        ##master端IP




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

 
 

2.4 修改minion配置文件

//将master指向syndic

[root@minion ~]# vim /etc/salt/minion
......
master:  192.168.30.244          ##改为syndic的IP


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

 
 

2.5 syndic端接收minion的key

[root@syndic ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
minion            //key
Rejected Keys:


[root@syndic ~]# salt-key -Ay
The following keys are going to be accepted:
Unaccepted Keys:
minion
Key for minion minion accepted.



[root@syndic ~]# salt-key -L
Accepted Keys:
minion             //key
Denied Keys:
Unaccepted Keys:
Rejected Keys:

 
 

2.6 master端接收syndic的key

[root@master ~]# salt-key -L
Accepted Keys:
Denied Keys:
Unaccepted Keys:
syndic
Rejected Keys:



[root@master ~]# salt-key -Ay
The following keys are going to be accepted:
Unaccepted Keys:
syndic             //key
Key for minion syndic accepted.




[root@master ~]# salt-key -L
Accepted Keys:
syndic             //key
Denied Keys:
Unaccepted Keys:
Rejected Keys:

 
 

2.7 在master端测试有几个minion端回应

[root@master ~]# salt '*' test.ping
minion:
    True


最顶层的master不知道自己有几个syndic，它只知道自己有多少个minion
