作用：為了不手動去安裝一臺一臺去salt-minion，並進重復的配置

一、環境

系統環境：

#cat /etc/redhat-release
CentOS Linux release 7.4.1708 (Core)

#python -V

Python 2.7.5

各節點環境說明：

二、hosts文件解析

#vim /etc/hosts

192.168.1.101 salt.node1.com
192.168.1.200 salt.node2.com
192.168.1.201 salt.node3.com

三、安裝salt-ssh

a.添加yum源：

*參考salt-stack官網：https://docs.saltstack.com/en/latest/topics/installation/rhel.html

# vim /etc/yum.repos.d/salt-stack.repo
[saltstack-repo]
name=SaltStack repo for Red Hat Enterprise Linux $releasever
baseurl=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest
enabled=1
gpgcheck=1
gpgkey=https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/SALTSTACK-GPG-KEY.pub
https://repo.saltstack.com/yum/redhat/$releasever/$basearch/latest/base/RPM-GPG-KEY-CentOS-7

b.安裝salt-ssh

#yum install salt-ssh -y

c.配置roster文件

*可以在user下面配置passwd，如不配置的話，就要使用salt-ssh ‘*‘ test.ping -i命令時配置輸入密碼進行認證

# vim /etc/salt/roster

node1:
host: 192.168.1.200
user: root
port: 22
node2:
host: 192.168.1.201
user: root
port: 22
四、配置state.sls文件及給復制相關文件到部署目錄

a.創建文件目錄

# vim install.sls

#salt_minion_install
minion_yum:             #把本地minions/yum.repos.d下和文件復制到要安裝minion的/etc/yum.repos.d下
  file.recurse:
    - name: /etc/yum.repos.d
    - source: salt://minions/yum.repos.d
    - user: root
    - group: root
    - file_mode: 644
    - dir_mode: 755
    - include_empty: True
minion_install:         #安裝salt-minion
  pkg.installed:
    - pkgs:
      - salt-minion
    - require:
      - file: minion_yum
    - unless: rpm -qa | grep salt-minion
minion_conf:           #復制準備好的minion配置文件復制到要安裝minion下的/etc/salt/minion下
  file.managed:
    - name: /etc/salt/minion
    - source: salt://minions/conf/minion
    - user: root
    - group: root
    - mode: 640
    - template: jinja
    - defaults:
      minion_id: {{ grains[‘fqdn_ip4‘][0] }}　　　　　　　　
    - require:
      - pkg: minion_install
minion_service:       #開機自動啟動
  service.running:
    - name: salt-minion
    - enable: True
    - require:
      - file: minion_conf

c.編寫minion配置文件

#vim minion

# resolved, then the minion will fail to start.
master: 192.168.1.101 #只用修改master地址

d.把salt源和epel源復制到指定目錄下

#cp /etc/yum.repos.d/salt-stack.repo /srv/salt/minions/yum.repos.d/

# cp /etc/yum.repos.d/epel.repo /srv/salt/minions/yum.repos.d/

e.最後查看一下目錄詳情：

# pwd
/srv/salt/minions

# tree
├── conf
│ └── minion
├── install.sls
└── yum.repos.d
├── epel.repo
└── salt-stack.repo

五、執行salt-ssh安裝salt-minion

#salt-ssh -i ‘*‘ state.sls minions.install

六、驗證安裝結果

*註：在最後我在salt-ssh這臺主機上安裝了salt-mater（yum install -y salt-master ）,不然下面的命令執行無效

# salt-key
