ansible 安装 httpd

1. 注意:提前进行完公钥复制
2. 安装 ansible 并进行配置
   1. 安装 yum install -q -y ansible

   2. 配置 vim /etc/ansible/hosts

      [sg1]
      192.168.10.7
      192.168.10.17
      [sg2]
      192.168.10.27

3. 在/root 下建立一个 httpd 文件夹
   mkdir /root/httpd

4. 进入文件夹并在文件中创建一个主 yaml 文件
   vim httpd_role.yml

   ---
   - hosts: all
     roles:
       - role: httpd

5. 创建 role 文件夹及子文件夹
   • roles
     • httpd
       • templates
         用于放模板文件

         • httpd.conf.j2
           将 http 的配置文件/etc/httpd/conf/httpd.conf 拷贝为 httpd.conf.j2

           Listen {{port}}

       • handlers
         用于放触发性的操作

         • main.yml

           - name: restart service
             service: name=httpd state=restarted

       • tasks
         主要的操作

         • main.yml
           引入各小操作

           ---
           - include: install.yml
           - include: config.yml
           - include: service.yml

         • install.yml
           通过 yum 进行安装

           - name: install
             yum:
               name: httpd
               state: present

         • config.yml
           将模板文件变为配置文件并拷贝到主机

           - name: config
             template:
               src: httpd.conf.j2
               dest: /etc/httpd/conf/httpd.conf
             notify: restart service

         • service.yml
           开启 httpd 服务

           - name: service
             service:
               name: httpd
               state: started
               enabled: yes

       • var
         存放变量号及其它可能变更的配置

         • main.yml

           port: 8888

6. 使用命令
   ansible-playbook /root/httpd_role.yml

建立 httpd 服务器，要求提供两个基于名称的虚拟主机:

1. www.X.com,页面文件目录为/web/vhosts/x;错误日志为
   /var/log/httpd/x.err，访问日志为/var/log/httpd/x.access

   <VirtualHost *:80>
       ServerName www.X.com
       DocumentRoot /web/vhosts/x
       <Directory "/web/vhosts/x">
           Require all granted
       </Directory>
       CustomLog "/var/log/httpd/x.access"
       ErrorLog "/var/log/httpd/x.err"
   </VirtualHost>

2. www.Y.com,页面文件目录为/web/vhosts/y;错误日志为 /var/log/httpd/www2.err
   ,访问日志为/var/log/httpd/y.access4. 重启 httpd
   systemctl restart httpd

   <VirtualHost *:80>
       ServerName www.Y.com
       DocumentRoot /web/vhosts/y
       <Directory "/web/vhosts/y">
           Require all granted
       </Directory>
       CustomLog "/var/log/httpd/y.access"
       ErrorLog "/var/log/httpd/y.err"
   </VirtualHost>

3. 为两个虚拟主机建立各自的主页文件 index.html，内容分别为其对应的主机名

   mkdir -p /web/vhosts/{x,y}
   echo '<h1>www.x.com</h1>' > /web/vhosts/x/index.html
   echo '<h1>www.y.com</h1>' > /web/vhosts/y/index.html

4. 重启 httpd
   systemctl restart httpd
