一、使用ansible的playbook实现自动化安装httpd
二、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
#创建配置文件
vim /opt/http_conf/y_com.conf
<VirtualHost *:80>
ServerName www.X.com
DocumentRoot "/web/vhosts/x"
<Directory "/web/vhosts/x">
Options None
AllowOverride None
Require all granted
</Directory>
ErrorLog "logs/x.err"
CustomLog "logs/x.access" combined
</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.access
# 创建配置文件
vim /opt/http_conf/y_com.conf
<VirtualHost *:80>
ServerName www.Y.com
DocumentRoot "/web/vhosts/y"
<Directory "/web/vhosts/y">
Options None
AllowOverride None
Require all granted
</Directory>
ErrorLog "logs/www2.err"
CustomLog "logs/y.access" combined
</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
# 分别创建index文件
echo "www.x.com" >/opt/http_index/x_index.html
echo "www.y.com" >/opt/http_index/y_index.html
（1）使用ansible推送配置文件以及主页文件
# 编辑playbooks文件
vim http_conf.yml

add 'warn: false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message.

# 出现警告提示用file创建文件夹更好
（2）编辑ansible主机的hosts文件
vim /etc/hosts
10.50.6.10 www.x.com
10.50.6.8 www.y.com
（3）测试访问是否正确
# 虽然两个主机都配置了x与y的页面，为了区分测试了2个主机不同的页面，也可以将hosts文件内的域名与主机调换一下做测试
[root@node3 opt]# curl http://www.x.com
www.x.com
[root@node3 opt]# curl http://www.y.com
www.y.com
