一、环境准备

1. 节点信息表

|--------------|-----------------|-------------|--------------------|------|
| 节点名称 | IP | 是否安装Ansible | 软件版本 | 配置 |
| ansible 管理节点 | 192.168.190.103 | 是 | ansible 2.9.27 | 2C2G |
| nginx 被管理节点 | 192.168.190.104 | 否 | nginx-1.24.0 | 8C4G |
| mysql 被管理节点 | 192.168.190.105 | 否 | mysql-boost-5.7.20 | 8C4G |
| php 被管理节点 | 192.168.190.106 | 否 | php-7.1.10 | 8C4G |

2. 防火墙以及地址解析

bash 复制代码 
四台机器均需要操作：
systemctl stop firewalld.service 
setenforce 0

cat << eof >> /etc/hosts
192.168.190.103 ansible
192.168.190.104 nginx
192.168.190.105 mysql
192.168.190.106 php
eof

3. 管理节点安装 ansible

bash 复制代码 
[root@ansible ~]# yum install -y epel-release
[root@ansible ~]# yum install -y ansible
[root@ansible ~]# ansible --version
ansible 2.9.27
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Aug  4 2017, 00:39:18) [GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]

4. 免密管理 ssh-keygen

bash 复制代码 
生成 SSH 密钥对：
[root@ansible ~]# ssh-keygen -t rsa      # 一直回车
# rsa表示生成RSA密钥对，RSA是一种非对称加密算法
[root@control ~]# ls .ssh/
id_rsa  id_rsa.pub       # id_rsa 是私钥文件；id_rsa.pub 是公钥文件

将本地主机上的SSH公钥复制到远程主机：
[root@ansible ~]# ssh 192.168.190.104 # ssh root@192.168.190.104，默认root
[root@ansible ~]# ssh 192.168.190.105
[root@ansible ~]# ssh 192.168.190.106
[root@ansible ~]# sshpass -p '123' ssh-copy-id 192.168.190.104
[root@ansible ~]# sshpass -p '123' ssh-copy-id 192.168.190.105
[root@ansible ~]# sshpass -p '123' ssh-copy-id 192.168.190.106

5. 编辑主机清单

diff 复制代码 
[root@ansible ~]# vim /etc/ansible/hosts
[nginx]
192.168.190.104 php_server_ip=192.168.190.106 nginx_html_path=/usr/local/nginx/html

[mysql]
192.168.190.105

[php]
192.168.190.106 php_server_ip=192.168.190.106 nginx_server_ip=192.168.190.104

6. 测试联通性

bash 复制代码 
[root@ansible ~]# ansible all -o -m ping
192.168.190.105 | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"}
192.168.190.104 | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"}
192.168.190.106 | SUCCESS => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"}, "changed": false, "ping": "pong"}

二、准备 roles 模块

1. 创建 roles 以及项目目录

一般 roles 目录会默认存在：

bash 复制代码 
[root@ansible ~]# mkdir /etc/ansible/roles/nginx/{files,templates,tasks,handlers,vars,defaults,meta} -p
[root@ansible ~]# mkdir /etc/ansible/roles/mysql/{files,templates,tasks,handlers,vars,defaults,meta} -p
[root@ansible ~]# mkdir /etc/ansible/roles/php/{files,templates,tasks,handlers,vars,defaults,meta} -p

[root@ansible ~]# touch /etc/ansible/roles/nginx/{defaults,vars,tasks,meta,handlers}/main.yml 
[root@ansible ~]# touch /etc/ansible/roles/mysql/{defaults,vars,tasks,meta,handlers}/main.yml 
[root@ansible ~]# touch /etc/ansible/roles/php/{defaults,vars,tasks,meta,handlers}/main.yml

2. 编写 nginx 模块

2.1 准备 files 相关文件

用来存放由 copy 模块或 script 模块调用的文件。

2.1.1 准备 nginx、论坛、博客安装包
bash 复制代码 
[root@ansible ~]# cd /etc/ansible/roles/nginx/files/
[root@ansible files]# ls
Discuz_X3.4_SC_UTF8.zip  nginx-1.24.0.tar.gz  wordpress-4.9.4-zh_CN.tar.gz
2.1.2 准备编译安装 nginx 脚本
bash 复制代码 
[root@ansible files]# vim lnmp.sh
#/bin/bash
nginx (){
nginxpath=`find / -name "*nginx*tar.gz" -exec dirname {} \; | sed -n '1p'`                #找到安装包路径
nginxapp=`find / -name "*nginx*tar.gz" 2> /dev/null |awk -F/ '{print $NF}' | sed -n '1p'` #打印安装包名称
systemctl status nginx.service > /dev/null
if [ $? -eq 0 ];then     #判断上一条命令返回值是否为真
echo  "nginx服务已安装"
else
useradd -M -s /sbin/nologin nginx  #创建用户
echo "正在安装nginx服务，请耐心等待"
tar xf  ${nginxpath}/${nginxapp} -C ${nginxpath} #解压安装包到其路径下
nginxd=`find  ${nginxpath} -maxdepth 1 -type d | grep  nginx- | awk -F/ '{print $NF}'` 
#只搜索当前目录，然后筛选出包含nginx- 字符串的目录，并打印这些目录的名称（去掉路径部分），-maxdepth 1表示只搜索当前目录，不搜索子目录
cd  ${nginxpath}/${nginxd}

2.1.3 创建共享目录脚本
bash 复制代码 
[root@ansible files]# vim nginx_nfs.sh
#!/bin/bash
echo "/usr/local/nginx/html *(rw)" > /etc/exports
# *(rw)表示所有主机都可以以读写模式访问该共享目录
# /etc/exports是NFS（Network File System）服务器的配置文件
chmod -R 777 /usr/local/nginx/html/
systemctl start rpcbind
systemctl start nfs

[root@ansible files]# ls
Discuz_X3.4_SC_UTF8.zip  lnmp.sh  nginx-1.24.0.tar.gz  nginx_nfs.sh  wordpress-4.9.4-zh_CN.tar.gz

2.2 准备 templates 相关文件

用来存放 jinjia2 模板，template 模块会自动在此目录中寻找 jinjia2 模板文件

2.2.1 编辑 nginx 配置文件模板

注意两个变量：php_server_ip，nginx_html_path

bash 复制代码 
[root@ansible files]# cd ../templates/
[root@ansible templates]# vim nginx.conf.j2
#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80

            root           html;
            fastcgi_pass   {{php_server_ip}}:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  {{nginx_html_path}}$fastcgi_script_name;
            include        fastcgi_params;
        }

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one

    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;

    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

2.3 编写 nginx 模块 task 任务文件

此目录应当包含一个 main.yml 文件，用于定义此角色的任务列表，此文件可以使用 include 包含其它的位于此目录的 task 文件。

bash 复制代码 
[root@ansible templates]# cd ../tasks/
[root@ansible tasks]# vim main.yml
- name: copy nginx package
  copy: src=/etc/ansible/roles/nginx/files/nginx-1.24.0.tar.gz dest=/opt
- name: copy wordpress package
  copy: src=/etc/ansible/roles/nginx/files/Discuz_X3.4_SC_UTF8.zip dest=/opt
- name: copy Discuz package
  copy: src=/etc/ansible/roles/nginx/files/wordpress-4.9.4-zh_CN.tar.gz dest=/opt
- name: install nginx shell
  script: /etc/ansible/roles/nginx/files/lnmp.sh nginx
- name: copy conf.j2
  template: src=/etc/ansible/roles/nginx/templates/nginx.conf.j2 dest=/usr/local/nginx/conf/nginx.conf owner=nginx group=nginx
- name: nfs shell
  script: /etc/ansible/roles/nginx/files/nginx_nfs.sh
- name: start nginx service
  service: enabled=true name=nginx state=started

3. 编写 mysql 模块

3.1 准备 files 相关文件

3.1.1 准备 mysql 安装包
bash 复制代码 
[root@ansible tasks]# cd ../../mysql/files/
[root@ansible files]# ls
mysql-boost-5.7.20.tar.gz
3.1.2 准备编译安装 mysql 脚本

同 2.1.2 脚本一致：

bash 复制代码 
[root@ansible files]# cp /etc/ansible/roles/nginx/files/lnmp.sh .
3.1.3 创建共享目录脚本
bash 复制代码 
[root@ansible files]# vim mysql_nfs.sh
#!/bin/bash
echo "/usr/local/mysql  *(rw)" > /etc/exports
chmod -R 777 /usr/local/mysql/
systemctl start rpcbind
systemctl start nfs

3.2 编写 mysql 模块 task 任务文件

此目录应当包含一个 main.yml 文件，用于定义此角色的任务列表，此文件可以使用 include 包含其它的位于此目录的 task 文件

bash 复制代码 
[root@ansible files]# cd ../tasks/
[root@ansible tasks]# vim main.yml
- name: copy package
  copy: src=/etc/ansible/roles/mysql/files/mysql-boost-5.7.20.tar.gz dest=/opt/
- name: install mysql shell
  script: /etc/ansible/roles/mysql/files/lnmp.sh mysql
- name: nfs shell
  script: /etc/ansible/roles/mysql/files/mysql_nfs.sh

4. 编写 php 模块

4.1 准备 files 相关文件

4.1.4 编辑 php-fpm 主配置文件
bash 复制代码 
[root@ansible files]# egrep -v "^;" php-fpm.conf | egrep -v "^$"
[global]
pid = run/php-fpm.pid
include=/usr/local/php/etc/php-fpm.d/*.conf
4.1.5 编辑 php-fpm 进程池配置文件

这步可选，如果直接复制配置文件至 templates 文件夹模板 .j2 文件自带变量会报错。

bash 复制代码 
[root@ansible files]# egrep -v "^;" www.conf | egrep -v "^$"
[www]
user = nginx
group = nginx
listen = 192.168.190.106:9000      # php 地址
listen.allowed_clients = 127.0.0.1,192.168.190.104  # nginx 地址
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

4.2 准备 templates 相关文件

bash 复制代码 
[root@ansible files]# cd ../templates/
[root@ansible templates]# vim www.conf.j2
[www]
user = nginx
group = nginx
listen = {{php_server_ip}}:9000
listen.allowed_clients = 127.0.0.1,{{nginx_server_ip}}
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

4.3 编写 php 模块 task 任务文件

此目录应当包含一个 main.yml 文件，用于定义此角色的任务列表，此文件可以使用 include 包含其它的位于此目录的 task 文件

bash 复制代码 
[root@ansible templates]# cd ../tasks/
[root@ansible tasks]# vim main.yml 
- name: copy package
  copy: src=/etc/ansible/roles/php/files/php-7.1.10.tar.bz2 dest=/opt/
- name: create mysql nfs path
  file: path=/usr/local/mysql/ state=directory
- name: create nginx nfs path
  file: path=/usr/local/nginx/html/ state=directory
- name: mount nfs mysql share
  ansible.builtin.mount: src=192.168.190.105:/usr/local/mysql path=/usr/local/mysql fstype=nfs opts=defaults state=mounted
- name: mount nfs nginx share 
  ansible.builtin.mount: src=192.168.190.104:/usr/local/nginx/html path=/usr/local/nginx/html fstype=nfs opts=defaults state=mounted
- name: install php shell
  script: /etc/ansible/roles/php/files/lnmp.sh php
- name: copy php-fpm.conf
  copy: src=/etc/ansible/roles/php/files/php-fpm.conf dest=/usr/local/php/etc/php-fpm.conf
- name: copy php.ini
  copy: src=/etc/ansible/roles/php/files/php.ini dest=/usr/local/php/lib/php.ini
- name: copy www.conf
  template: src=/etc/ansible/roles/php/templates/www.conf.j2 dest=/usr/local/php/etc/php-fpm.d/www.conf
- name: start php-fpm server
  service: name=php-fpm state=started

5. 编写 roles 示例

bash 复制代码 
[root@ansible vars]# cd /etc/ansible/
[root@ansible ansible]# vim lnmp.yml
---
- hosts: nginx
  remote_user: root
  roles:
     - nginx
- hosts: mysql
  remote_user: root
  roles:
     - mysql
- hosts: php
  remote_user: root
  roles:
     - php
...

三、执行角色剧本并验证

1. 查看目录

bash 复制代码 
[root@ansible ansible]# ls
ansible.cfg  hosts  lnmp.yml  roles
[root@ansible ansible]# tree
.
├── ansible.cfg

    └── php
        ├── defaults
        │   └── main.yml
        ├── files

        ├── templates
        │   └── www.conf.j2
        └── vars
            └── main.yml

2. 执行剧本

3. 验证 Wordpress

3.1 创建一个新的配置文件 wp-config.php

bash 复制代码 
[root@nginx ~]# cd /usr/local/nginx/html/wordpress
[root@nginx wordpress]# cp wp-config-sample.php wp-config.php
[root@nginx wordpress]# vim wp-config.php
// ** MySQL 设置 - 具体信息来自您正在使用的主机 ** //
/** WordPress数据库的名称 */
define('DB_NAME', 'wordpress');

/** MySQL数据库用户名 */
define('DB_USER', 'wordpress');

/** MySQL数据库密码 */
define('DB_PASSWORD', '123456');

/** MySQL主机 */
define('DB_HOST', '192.168.190.105:3306');

3.2 浏览器访问 wordpress

访问192.168.190.104/wordpress/index.php

4. 验证 Discuz

4.1 创建一个新的配置文件 config_global.php

bash 复制代码 
[root@nginx ~]# cd /usr/local/nginx/html/bbs/config
[root@nginx config]# cp config_global_default.php config_global.php
[root@nginx config]# chmod 777 config_global.php
[root@nginx config]# vim config_global.php
// ----------------------------  CONFIG DB  ----------------------------- //
$_config['db']['1']['dbhost'] = '192.168.190.105:3306';  # 数据库地址端口
$_config['db']['1']['dbuser'] = 'bbsuser';               # 用户名
$_config['db']['1']['dbpw'] = '123456';                  # 密码
