1. install

apt-get install python-software-properties
apt install software-properties-common
apt-get update
apt-get install salt-master
apt-get install salt-minion

1. config

if master: vim /etc/salt/master

interface: master ip		            //（注意：key:空格value之间不能漏掉空格，否则报错）
auto_accept: True

if minion: vim /etc/salt/minon

master: master ip
id: minion ip

1. usual salt cmd //(salt, salt-run, salt-cp 适用于master)

salt-call test.ping					    //（适用master and minion）
salt 'hostname' test.ping 				//(适用minion)
//（可选）/etc/salt/minion_id:存放minion master: Accepted Keys
salt-key -L						        // list all salt-key
salt '*' cmd.run 'df -lh'				//master run cmd on minion host
salt-call cmd.run 'hostname -I' 		//minion run cmd on minion host
salt-run manage.down     			    //查看所有没在线minion
salt-run manage.up       				//查看所有在线minion
salt-key -a minion_key				    //接受某个minion-key 大写A介绍所有
salt-key -d minion_key				    //删除某个minion-key大写D删除所有
//将master中的文件复制到制定minion主机，可重命名
salt-cp 'minion_ip' master_txt minion_dir/rename.txt
salt '*' pkg.version python 			//显示软件包版本信息
salt '*' pkg.install git 				//install git on minion
salt '*' pkg.install pkgs=['vim','rpm']		//install two more pkgs
salt '*' network.connect google-public-dns-a.google.com port=53 proto=udp
salt '*' service.start mysql 			//启动mysql服务
salt '*' cmd.run 'service mysql start'

1. get data

A. Grains are used to get static data about your systems

B. Salt pillar is used to deliver data to your systems.

C. SaltStack configuration management lets you create a re-usable configuration template, called a state

salt -G 'os:Ubuntu' test.ping			//static data Grains
salt -E '192.168.43.*' test.ping		//regular expression
salt -L 'minion1,minion2' test.ping 	//in a list

1. salt state
   
   vim /srv/salt/nettools.sls

install_id_whatever:
  pkg.installed:
    - pkgs:                             // multi pkgs
      - rsync
      - lftp
      - curl
    - name: git                         //single pkg

run cmd to install pkgs in nettools.sls on minion host

salt '*' state.apply nettools

or

salt '*' state.sys nettools.sls

vim /srv/salt/test.sls

install_id_test:
    pkg.install:
        -pkgs:
            - mysql-server
            - django

vim /srv/salt/top.sls

base:
    '*':
        - nettools
    'specific_minion_host'
        - test

salt '*' state.apply // default use top.sls

salt 'specific_minion_host' state.apply test.sls
