一、使用ansible的playbook實(shí)現(xiàn)自動(dòng)化安裝httpd
二栓辜、建立httpd服務(wù)器，要求提供兩個(gè)基于名稱的虛擬主機(jī):
1、www.X.com嚣镜，頁面文件目錄為/web/vhosts/x;錯(cuò)誤日志為/var/log/httpd/x.err，訪問日志為/var/log/httpd/x.access
#創(chuàng)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橘蜜、www.Y.com菊匿，頁面文件目錄為/web/vhosts/y;錯(cuò)誤日志為 /var/log/httpd/www2.err，訪問日志為/var/log/httpd/y.access
# 創(chuàng)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计福、為兩個(gè)虛擬主機(jī)建立各自的主頁文件index.html跌捆，內(nèi)容分別為其對(duì)應(yīng)的主機(jī)名
# 分別創(chuàng)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頁文件
# 編輯playbooks文件
vim http_conf.yml

（2）編輯ansible主機(jī)的hosts文件
vim /etc/hosts
10.50.6.10 www.x.com
10.50.6.8 www.y.com
（3）測(cè)試訪問是否正確
# 雖然兩個(gè)主機(jī)都配置了x與y的頁面，為了區(qū)分測(cè)試了2個(gè)主機(jī)不同的頁面象颖，也可以將hosts文件內(nèi)的域名與主機(jī)調(diào)換一下做測(cè)試
[root@node3 opt]# curl http://www.x.com
www.x.com
[root@node3 opt]# curl http://www.y.com
www.y.com
