1、使用ansible的playbook实现自动化安装httpd

1、ansible和各主机之间做免密登录 略

2、配置ansible的host主机

[root@centos7a playbook]#cat /etc/ansible/hosts 
[wang]
192.168.43.106
192.168.43.147
192.168.43.137

3、准备配置文件模板：

centos6 和centos7 各一个配置文件模板

4、准备playbook脚本

[root@centos7a playbook]#cat httpd.yml 
- hosts: wang
	remote_user: root

	tasks:
		- name: install
			yum: name=httpd
		- name: config
			template: src=httpd6.conf.j2 dest=/etc/httpd/conf/httpd.conf
			when: ansible_distribution_major_version == "6"
			notify: httpd restart
		- name: config
			template: src=httpd7.conf.j2 dest=/etc/httpd/conf/httpd.conf
			when: ansible_distribution_major_version == "7"
			notify: httpd restart
		- name: service
			service: name=httpd state=started enabled=yes

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

5、执行脚本安装：

[root@centos7a playbook]#ansible-playbook httpd.yml

** 6、结果验证**

2、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 (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.access (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

1、确保配置文件中有此配置： [root@ka1 conf.d]#cat /etc/httpd/conf/httpd.conf IncludeOptional conf.d/*.conf

2、创建独立的配置文件：

[root@ka1 conf.d]#vim /etc/httpd/conf.d/test.conf

<directory "/var/www/html/"> Require all granted ALLowOverride All </directory>

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

<VirtualHost *:80> DocumentRoot "/web/vhosts/y" ServerName www.Y.com ErrorLog "/var/log/httpd/www2.err" CustomLog "/var/log/httpd/y.access" combined <Directory "/web/vhosts/y">
require all granted </Directory> </VirtualHost>

2、创建虚拟主机目录： [root@ka1 conf.d]#tree /web/vhosts/ /web/vhosts/ ├── x │   └── index.html └── y └── index.html [root@ka1 conf.d]#cat /web/vhosts/{x,y}/index.html www.X.com www.Y.com

4、重启httpd [root@ka1 conf.d]#systemctl restart httpd

5、PC机修改hosts文件：C:\Windows\System32\drivers\etc\hosts

6、浏览器访问：

www.X.com

www.Y.com

7、查看日志文件： [root@ka1 conf.d]#ll /var/log/httpd/ [root@ka1 httpd]#ll total 32 -rw-r--r-- 1 root root 8412 Apr 9 15:02 access_log -rw-r--r-- 1 root root 11300 Apr 9 15:13 error_log -rw-r--r-- 1 root root 0 Apr 9 15:03 www2.err -rw-r--r-- 1 root root 192 Apr 9 15:13 x.access -rw-r--r-- 1 root root 0 Apr 9 15:03 x.err -rw-r--r-- 1 root root 3788 Apr 9 15:13 y.access
