wordpress是直接套用的niginx的blog文件，所以apache的伪静态没做！

坑之一：

[root@web02 extra]# /application/apache/bin/apachectl -t

[Tue Jun 13 21:49:01 2017] [warn] _default_ VirtualHost overlap on port 80, the first has precedence

[Tue Jun 13 21:49:01 2017] [warn] _default_ VirtualHost overlap on port 80, the first has precedence

Syntax OK

apache配置检查的时候出现的不明原因的错误！

[root@web02 extra]# vim /etc/hosts

[root@web02 extra]# curl www.etiantian.org

apache www

[root@web02 extra]# curl etiantian.org

apache www

[root@web02 extra]# curl bbs.etiantian.org

apache www

[root@web02 extra]# curl blog.etiantian.org

apache www                 #网页读取不到blog和bbs的网页  都是显示的apache ww

解答：NameVirtualHost *:80   后续对比上课的web02发现httpd-vhosts.conf第一行少了此句！！！
