配置管理之SLS
Salt State SLS描述文件(YAML)
名称ID声明 默认是name声明
备注： 一个ID声明下面。状态模块不能重复使用
例：
apache-install:
pkg.installed:
- names:
- httpd
- httpd-devel
apache-service: # ID声明，高级状态，ID必须唯一。
service.running: # State声明 状态声明
- name: httpd # 选项声明
- enable: True
php:
pkg.installed
常用状态模块介绍
1）pkg （https://docs.saltstack.com/en/latest/ref/states/all/salt.states.pkg.html#module-salt.states.pkg）
pkg.installed # 安装
pkg.latest # 确保最新版本
pkg.remove # 卸载
pkg.purge # 卸载并删除配置文件
# 同时安装多个包
common_packages:
pkg.installed:
- pkgs:
- unzip
- dos2unix
- salt-minion: 2015.8.5-1.el6
2）file （https://docs.saltstack.com/en/latest/ref/states/all/salt.states.file.html#module-salt.states.file）
salt:// 表示当前环境的根目录。例如：
那么salt://lamp/files/httpd.conf 表示 /srv/salt/lamp/files/httpd.conf
3）service （https://docs.saltstack.com/en/latest/ref/states/all/salt.states.service.html#module-salt.states.service）
redis:
service.running:
- enable: True # 开机自启动
- reload: True # 重载
LAMP架构slat实现安装、配置、启动
1.安装软件包 pkg
2.修改配置文件 file
3.启动服务 service
lamp.sls文件内容如下
lamp-pkg:
pkg.installed:
- pkgs:
- httpd
- php
- mariadb
- mariadb-server
- php-mysql
- php-cli
- php-mbstring
apache-config:
file.managed:
- name: /etc/httpd/conf/httpd.conf
- source: salt://lamp/files/httpd.conf

- group: root
- mode: 644
php-config:
file.managed:
- name: /etc/php.ini
- source: salt://lamp/files/php.ini
- user: root
- group: root
