Salt-ssh 自动安装salt-minion

作用：为了不手动去安装一台一台去salt-minion，并进重复的配置

一、环境

系统环境：

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

#python -V

Python 2.7.5

各节点环境说明：

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、安装salt-ssh

a.添加yum源：

*参考salt-stack官网：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.安装salt-ssh

#yum install salt-ssh -y

c.配置roster文件

*可以在user下面配置passwd，如不配置的话，就要使用salt-ssh '*' test.ping -i命令时配置输入密码进行认证

# vim /etc/salt/roster

node1:
host: 192.168.1.200
user: root
port: 22
node2:
host: 192.168.1.201
user: root
port: 22

#salt-ssh '*' test.ping -i       #进行密码认证
四、配置state.sls文件及给复制相关文件到部署目录

a.创建文件目录

# mkdir -p /srv/salt/minions

# mkdir -p /srv/salt/minions/conf 

# mkdir -p /srv/salt/minions/yum.repos.d

b.编写安装minions的sls文件--install.sls

# cd /srv/salt/minions/

# vim install.sls

#salt_minion_install
minion_yum:             #把本地minions/yum.repos.d下和文件复制到要安装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:         #安装salt-minion
  pkg.installed:
    - pkgs:
      - salt-minion
    - require:
      - file: minion_yum
    - unless: rpm -qa | grep salt-minion
minion_conf:           #复制准备好的minion配置文件复制到要安装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:       #开机自动启动
  service.running:
    - name: salt-minion
    - enable: True
    - require:
      - file: minion_conf

c.编写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源复制到指定目录下

#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.最后查看一下目录详情：

# pwd
/srv/salt/minions

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

五、执行salt-ssh安装salt-minion

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

六、验证安装结果

*注：在最后我在salt-ssh这台主机上安装了salt-mater（yum install -y salt-master ）,不然下面的命令执行无效

# salt-key
