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
