master和minion之间用秘钥双向加密

[root@node1 /]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

root@node1 /]# yum -y install salt-master

/etc/init.d/salt-master start

[root@node1 /]#vim /etc/hosts

10.240.17.100 node1

10.240.17.103 node2

[root@node2]# vim /etc/salt/minion

16 master 211.103.138.122

systemctl start salt-minion

tree /etc/salt/minion/ ####如果主机名变了需要删除/etc/salt/minion_id文件相当于缓存

[root@node1/]# tree /etc/salt/master ###如果主机名改了需要删除 minions_pre下对应的minion客户端名字

[root@node1/]#salt-key -A ###添加所有主机

[root@node1/]#salt '*' test.ping #所有的主机执行模块ping操作

###master和minion通过zeromq消息队列来通信，所有的minion都连到master的4505端口上，当master发送指令的时候通过4506给minion发送消息

[root@node1/]#salt '*' cmd.run 'w' ###远程执行命令

[root@node1/]# vim /etc/salt/master

[root@node1/]# cd /srv/salt/base

vim apache.sls

apache-install:                          ###ID状态唯一标示
  pkg.installed:                          ###pkg是个状态模块，installed是状态模块的方法
    - name: httpd     ### name是个方法参数 httpd是这台机子应该有个httpd,如果有就上面都不做，如果没有就安装。 

apache-service:                     ###
  service.running:                   ###service状态模块，runing状态模块方法
    - name: httpd                     ###name方法参数 
    - enable: True                     ###enable方法参数    true是保证httpd应该处于启动，如果启动了什么都不做，如果没有就启动

[root@node1 base]# salt 'node2' state.sls apache #########执行apache.sls方法命令

[root@node1 base]# mkdir web && mv apache.sls web

[root@node1 base]# salt 'node2' state.sls web.apache ####以.来区别层次关系，而不是用/

[root@node1 base]# vim /etc/salt/master

329 state_top: top.sls

[root@node1 base]# vim top.sls

base:
  'node1' :
    - web.apache
  'node2' :
    - web.apache

[root@node1 base]# salt '*' state.highstate ###高级状态，去查top.sls，然后根据编排来执行各自的任务

[root@node1 base]# cd web

[root@node1 web]# vim lamp.sls
