实验目标
使用SaltStack部署apache和php
修改master的配置文件，指定base环境路径，base环境是必须指定的
[[email protected] base]# grep -9 ^file_roots /etc/salt/master |grep -v ^# file_roots: base: - /srv/salt/base dev: - /srv/salt/dev test: - /srv/salt/test prod: - /srv/salt/prod
创建目录
[[email protected] base]# mkdir -p /srv/salt/{base,dev,test,prod} [[email protected]-node1 base]# tree /srv/salt/ /srv/salt/ ├── base ├── dev ├── prod └── test
重启master
[[email protected] base]# systemctl restart salt-master
在base目录下面创建一个web目录用于存放web相关的sls文件
[[email protected] base]# mkdir -p web
cd到bash/web目录里面创建apache.sls文件
[[email protected] base]# cd web/ [[email protected]-node1 web]# cat apache.sls apache-install: #id 名字自己取 需要形象一点， 一个id下面一个状态只能出现一次 pkg.installed: #pkg 是状态模块，installed 是模块里面的方法 - name: httpd #方法里面的参数 apache-service: service.running: - name: httpd - enable: True #设置开机自动启动
#yaml里面格式有严格的要求，注释用#号，不能有table，- 两边需要空格，缩进用2个空格层级关系后面要加分号
执行状态模块部署服务
[[email protected] base]# salt "linux-node2*" state.sls apache linux-node2.example.com: ---------- ID: apache-install Function: pkg.installed Name: httpd Result: True Comment: Package httpd is already installed. Started: 14:58:09.228934 Duration: 633.681 ms Changes: ---------- ID: apache-service Function: service.running Name: httpd Result: True Comment: Service httpd is already enabled, and is running Started: 14:58:09.863302 Duration: 310.567 ms Changes: ---------- httpd: True Summary ------------ Succeeded: 2 (changed=1) Failed: 0 ------------ Total states run: 2
#此时node2 上面已经部署好了apache
高级状态的使用 需要在master配置文件里面打开 state_top: top.sls并重启master
[[email protected] web]# grep -n ^state_top /etc/salt/master
329:state_top: top.sls
[[email protected] web]# systemctl restart salt-master
在bese环境目录下面添加top.sls
[[email protected] base]# more top.sls base: ‘linux-node2.example.com‘: - web.apache ‘linux-node1.example.com‘: - web.apache [[email protected]-node1 base]# pwd /srv/salt/base
执行高级模块方法，高级方法到 base下面找top.sls 文件编排告诉每个minion需要干什么
一般生产环境用高级状态多些
[[email protected] base]# salt "*" state.highstate linux-node1.example.com: ---------- ID: apache-install Function: pkg.installed Name: httpd Result: True Comment: Package httpd is already installed. Started: 15:23:08.597951 Duration: 709.521 ms Changes: ---------- ID: apache-service Function: service.running Name: httpd Result: True Comment: Service httpd is already enabled, and is in the desired state Started: 15:23:09.308417 Duration: 233.623 ms Changes: Summary ------------ Succeeded: 2 Failed: 0 ------------ Total states run: 2 linux-node2.example.com: ---------- ID: apache-install Function: pkg.installed Name: httpd Result: True Comment: Package httpd is already installed. Started: 15:23:09.171596 Duration: 721.901 ms Changes: ---------- ID: apache-service Function: service.running Name: httpd Result: True Comment: Service httpd is already enabled, and is in the desired state Started: 15:23:09.894209 Duration: 221.615 ms Changes: Summary ------------ Succeeded: 2 Failed: 0 ------------ Total states run: 2
上面我们使用了2个状态模块pkg和service，下面我们使用file文件配置模块
模块使用参考文档
https://www.unixhot.com/docs/saltstack/ref/states/all/salt.states.file.html#module-salt.states.file
在base/web目录下面添加一个lamp.sls,
一般在添加里面的内容之前需要在外面找一台服务器进行测试拿到准确的包信息后再进行配置
[[email protected] web]# cat lamp.sls
lamp-install:
pkg.installed:
- pkgs:
- httpd
- php
- php-pdo
- php-mysql
apache-config:
file.managed:
- name: /etc/httpd/conf/httpd.conf #服务实际使用的文件路径
- source: salt://web/files/httpd.conf #salt的源文件用于分发到minion上面 路径是base目录下面的web 这里也支持http和ftp方式
- user: root
- group: root
- mode: 644
php-config:
file.managed:
- name: /etc/php.ini
- source: salt://web/files/php.ini
- user: root
- group: root
- mode: 644
lamp-service:
service.running:
- name: httpd
- enable: True
拷贝源文件到base/web目录下，这个根据自己的实际情况找源文件拷贝过来
[[email protected] web]# cp /etc/httpd/conf/httpd.conf /srv/salt/base/web/files/
[[email protected] web]# cp /etc/php.ini /srv/salt/base/web/files/
执行状态模块部署服务
