Saltstack_使用指南15_多master

1. 主机规划

实现2个master，当这两个master运行时都可以向minion发送命令。

salt 版本

 [root@salt100 ~]# salt --version
 salt 2018.3. (Oxygen)
 [root@salt100 ~]# salt-minion --version
 salt-minion 2018.3. (Oxygen)

2. 多master架构

说明：

根据规划在salt01创建冗余的master。

3. 多master实现步骤

3.1. 创建冗余的master

yum install -y salt-master    

3.2. 拷贝主master的key和配置到冗余的master

 # 拷贝的秘钥
 /etc/salt/pki/master/master.pem
 /etc/salt/pki/master/master.pub
 # 拷贝主master的配置
 /etc/salt/master
 # 拷贝主master的目录
 /srv

3.3. 启动冗余master

 systemctl enable salt-master.service  # 开机自启动
 systemctl start salt-master.service   # 启动salt-master

3.4. 配置minion去连接冗余master并重启minion

每台minion机器都操作

 [root@salt02 ~]# vim /etc/salt/minion
 …………
 # Set the location of the salt master server. If the master server cannot be
 # resolved, then the minion will fail to start.
 #master: salt
 # 修改后的配置如下
 master:
   - salt100
   - salt01
 …………
 [root@salt02 ~]# systemctl restart salt-minion.service 

3.5. 在冗余master接受minion的key

 [root@salt01 ~]# salt-key
 Accepted Keys:
 Denied Keys:
 Unaccepted Keys:
 salt01
 salt02
 salt03
 salt100
 Rejected Keys:
 [root@salt01 ~]# salt-key -A
 The following keys are going to be accepted:
 Unaccepted Keys:
 salt01
 salt02
 salt03
 salt100
 Proceed? [n/Y] Y
 Key for minion salt01 accepted.
 Key for minion salt02 accepted.
 Key for minion salt03 accepted.
 Key for minion salt100 accepted.

4. 多master操作示例

 salt '*' pillar.items
 salt '*' pillar.item level1:level2:my_user:
 salt '*' grains.item roles
