saltsack自动化配置day02：之配置管理-LAMP自动化部署

一、基础知识

1、声明id

之前提到过saltstack的脚本是使用YAML格式来渲染的，YAML是python中指代字典类型数据结构的结构序列化格式，基本上的结构就是键值对的形式，需要注意的是SLS文件中每个小节的key称为ID，这个ID必须全局唯一不然会出现错误。

在一个总的id下面，一个模块只能用一次

2、声明name

当你没有设置name声明的时候，id就是name

3、有name和没有那么的区别

1、有name

apache-config:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://apache/files/httpd.conf
    - user: root
    - group: root
    - mode: 644
	
php-config:
  file.managed:
    - name: /etc/httpd/conf/php.ini:
    - source: salt://web/files/php.ini
    - user: root
    - group: root
    - mode: 644

2、没有name

/etc/httpd/conf/httpd.conf:
  file.managed: 
    - source: salt://web/files/httpd.conf
    - user: root
    - group: root
    - mode: 644

/etc/httpd/conf/php.ini:
  file.managed: 
    - source: salt://web/files/php.ini
    - user: root
    - group: root
    - mode: 644

4、多个文件的2种写法

1、第一种写法

/etc/httpd/conf/httpd.conf:
  file.managed: 
    - source: salt://web/files/httpd.conf
    - user: root
    - group: root
    - mode: 644

/etc/httpd/conf/php.ini:
  file.managed: 
    - source: salt://web/files/php.ini
    - user: root
    - group: root
    - mode: 644

2、第二种写法（对于文件推荐写法）

apache-config:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://apache/files/httpd.conf
    - user: root
    - group: root
    - mode: 644
	
php-config:
  file.managed:
    - name: /etc/httpd/conf/php.ini:
    - source: salt://web/files/php.ini
    - user: root
    - group: root
    - mode: 644
	

5、各自的优缺点

第二种写法:

依赖的时候id名很短，好记忆

第一种写法：

很清晰，看到文件就知道是那个文件

二. 部署思路

1. 将lamp分成3部分：软件包、配置文件、服务； 
2. 确认安装的软件包名、配置文件路径、服务名等； 
3. 按以上信息编写yaml文件；

三. 编写lamp.sls

[root@salt-master salt]# pwd
/srv/salt
[root@salt-master salt]# ls
dev  init  prod  test  top.sls
[root@salt-master salt]# cat dev/lamp.sls 
lamp-pkg-install:
  pkg.installed:
    - names:
      - httpd
      - php
      - php-fpm
      - mysql
      - mysql-server
      - php-mysql
      - php-pdo

apache-service:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source:
      - salt://dev/files/httpd.conf
    - user: root
    - group: root
    - mode: 644
  service.running:
    - name: httpd
    - enable: True

mysql-service:
  file.managed:
    - name: /etc/my.cnf
    - source:
      - salt://dev/files/my.cnf
    - user: root
    - group: root
    - mode: 644
  service.running:
    - name: mysqld
    - enable: True

php-fpm-service:
  service.running:
    - name: php-fpm
    - enable: True
[root@salt-master salt]# cat top.sls 
base:
  '*':
    - init.dns

dev:
  'node*.test.com':
  - lamp
[root@salt-master salt]# ls dev/
files  lamp.sls
[root@salt-master salt]# ls dev/files/
httpd.conf  my.cnf
[root@salt-master salt]# 

执行salt '*' state.highstate查看结果：

 [root@salt-master salt]# salt-key -L
Accepted Keys:
master.test.com
node1.test.com
node2.test.com
Denied Keys:
Unaccepted Keys:
Rejected Keys:
[root@salt-master salt]# salt '*' state.highstate
