httpd實戰

1、使用ansible的playbook實現自動化安裝httpd

ansible管理主控與被管理機器已實現ssh免密登錄

主機清單中新增如下信息
[root@ansible ansible-playbook]# cat /etc/ansible/hosts 
[httpd]
192.168.0.222
#查看httpd組內機器連接狀態
[root@ansible ~]# ansible httpd -m ping 
192.168.0.222 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": false, 
    "ping": "pong"
}
配置ansible-playbook  yml文件
[root@ansible ansible-playbook]# cat install-httpd.yml 
- hosts: httpd
  remote_user: root
  tasks:
  - name: install the latest version of Apache
    yum:
        name: httpd
        state: latest
安裝httpd
[root@ansible ansible-playbook]# ansible-playbook install-httpd.yml 

執行結果：

2、建立httpd服務器，要求提供兩個基於名稱的虛擬主機:
(1)www.X.com，頁面文件目錄爲/web/vhosts/x;錯誤日誌爲/var/log/httpd/x.err，訪問日誌爲/var/log/httpd/x.access
(2)www.Y.com，頁面文件目錄爲/web/vhosts/y;錯誤日誌爲 /var/log/httpd/www2.err，訪問日誌爲/var/log/httpd/y.access
(3)爲兩個虛擬主機建立各自的主頁文件index.html，內容分別爲其對應的主機名

[root@ansible-client ~]# cat /etc/httpd/conf.d/x.conf 
<VirtualHost 192.168.0.112:80>
 DirectoryIndex index.html
 ServerName www.X.com
 DocumentRoot "/web/vhosts/x"
 ErrorLog "/var/log/httpd/x.err"
 CustomLog  /var/log/httpd/x.access  combined
 <Directory "/web/vhosts/x">
  Options -Indexes +FollowSymlinks
  AllowOverride All
  Require all granted
 </Directory>
</VirtualHost>

[root@ansible-client ~]# cat /etc/httpd/conf.d/y.conf 
<VirtualHost 192.168.0.112:80>
 DirectoryIndex index.html
 ServerName www.Y.com
 DocumentRoot "/web/vhosts/y"
 ErrorLog "/var/log/httpd/y.err"
 CustomLog  /var/log/httpd/y.access  combined
 <Directory "/web/vhosts/y">
  Options -Indexes +FollowSymlinks
  AllowOverride All
  Require all granted
 </Directory>
</VirtualHost>

[root@ansible-client ~]# mkdir -p /web/vhosts/{x,y}
[root@ansible-client ~]# echo 'www.X.com' > /web/vhosts/x/index.html
[root@ansible-client ~]# echo 'www.Y.com' > /web/vhosts/y/index.html

[root@ansible-client]# httpd -t
Syntax OK

[root@ansible-client ~]# systemctl  restart httpd

[root@ansible-client ~]#  curl www.X.com
www.X.com

[root@ansible-client ~]#  curl www.Y.com
www.Y.com
