[PHP知识库]playbook部署lamp（循环、事实、机密）

一、环境准备

二、实验步骤

开始之前先关闭防火墙和selinux

创建项目文件夹

[root@ansible ansible]# cd lamp/
[root@ansible lamp]# tree
.
├── conf
│   ├── httpd.conf
│   ├── httpd-vhosts.conf
│   ├── index.php
│   └── www.conf
├── install
│   └── index.php
└── vars
    ├── packages.yml
    ├── pa.yml
    ├── service.yml
    └── user.yml

3 directories, 9 files

把虚拟站点文件传输到node服务器上

[root@ansible lamp]# cat conf/httpd-vhosts.conf 
<VirtualHost *:80>
    DocumentRoot "/var/www/html"
    ServerName www.wjj.com
    ProxyRequests Off
    ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/$1 
    <Directory "/var/www/html">      
        Options none
        AllowOverride none
        Require all granted
    </Directory>
</VirtualHost>

编写需要传到部署机器的index.php文件

[root@ansible lamp]# cat conf/index.php 
<?php
    phpinfo();
?>

编写需要安装的服务的安装包文件、用户文件、服务文件

[root@ansible lamp]# cat vars/service.yml 
service:
  - httpd
  - mariadb
  - php-fpm
[root@ansible lamp]# cat vars/user.yml 
name:
 - apache
 - mysql
 - php

[root@ansible lamp]# cat vars/packages.yml 
tools:
  - httpd*
  - mariadb*
  - php* 

编写部署lamp的lamp.yml

[root@ansible lamp]# cat install/lamp.yml 
---
- name: "install httpd* mariadb* php* service"
  hosts: 192.168.47.129
  gather_facts: no
  vars_files:
    - /etc/ansible/lamp/vars/packages.yml
    - /etc/ansible/lamp/vars/user.yml
    - /etc/ansible/lamp/vars/service.yml  
  tasks:
    - name: "install"
      yum: 
        name: "{{ item }}"
        state: present
      loop: "{{ tools }}"

    - name: "create user"
      user:
        name: "{{ item }}"
        state: present
        system: yes
        create_home: no
        shell: /sbin/nologin
      loop: "{{ name }}"  

    - name: "copy is httpd.conf "
      copy:
        src: /etc/ansible/lamp/conf/httpd.conf 
        dest: /etc/httpd/conf/httpd.conf

    - name: "copy is vhosts.conf"
      copy:
        src: /etc/ansible/lamp/conf/httpd-vhosts.conf
        dest: /etc/httpd/conf.d/httpd-vhosts.conf

    - name: "copy is index.php"
      copy:
        src: /etc/ansible/lamp/conf/index.php
        dest: /var/www/html/index.php

    - name: "copy is www.conf"
      copy:
        src: /etc/ansible/lamp/conf/www.conf
        dest: /etc/php-fpm.d/www.conf  

    - name: "stopped is firewalld"
      service: 
        name: firewalld
        state: stopped
        enabled: no
    - name: "setenforce 0"
      shell: "setenforce 0"

    - name: "httpd mariadb php is enabled"
      service:
        name: "{{ item }}"
        state: started
        enabled: yes
      loop: "{{ server }}"        

运行结果
