APAX-5017PG 项目开发全程记录 - 筹备篇

主域名：www.test.com ，如何让辅助域名：www.daixuan.com 自动跳转到主域名？
Rewrite：301永久重定向，302临时重定向

前提是LAMP和Discuz论坛www.test.com可以通过本地访问，widnows的hosts文件添加：192.168.101.230 www.test.com www.daixuan.com www.daixuanlinux.com

1、修改虚拟主机配置文件
[root@daixuan ~]# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf 添加红色的rewrite模块
<VirtualHost *:80>
# ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "/data/www"
ServerName www.test.com
ServerAlias www.daixuan.com
# ErrorLog "logs/dummy-host.example.com-error_log"
# CustomLog "logs/dummy-host.example.com-access_log" common
<IfModule mod_rewrite.c>
RewriteEngine on Rewrite打开
RewriteCond %{HTTP_HOST} ^www.daixuan.com$ 条件：满足www.daixuan.com
RewriteRule ^/(.*)$ http://www.test.com/$1 [R=301,L] 规则：跳转到www.test.com
</IfModule> /(.*)$表示/任何内容
<Directory /data/www/abc/>
AllowOverride AuthConfig
AuthName "Please input your name and password"
AuthType Basic
AuthUserFile /data/.htpasswd
require valid-user
</Directory>
</VirtualHost>

2、重启Apache
[root@daixuan ~]# apachectl restart

3、测试
浏览器打开：www.daixuan.com 自动跳转到www.test.com，说明跳转成功。
[root@daixuan ~]# curl -x 192.168.101.230:80 www.daixuan.com/123456789 -I
HTTP/1.1 301 Moved Permanently
Date: Tue, 01 Dec 2015 02:22:09 GMT
Server: Apache/2.2.31 (Unix) PHP/5.4.45
Location: http://www.test.com//123456789 Content-Type: text/html; charset=iso-8859-1

4、拓展如果希望www.123.com和www.daixuan.com都跳转到www.test.com,怎么修改配置文件？

如果需要PC机测试虚拟机的Discuz论坛，需要配置windows的hosts文件
192.168.101.230 www.test.com www.daixuan.com www.daixuanlinux.com www.123.com

修改虚拟主机配置文件[root@daixuan ~]# vim /usr/local/apache2/conf/extra/httpd-vhosts.conf 添加红色的rewrite模块
<VirtualHost *:80>
# ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "/data/www"
ServerName www.test.com
ServerAlias www.daixuan.com
ServerAlias www.123.com 设置/data/www目录的别名：www.123.com
# ErrorLog "logs/dummy-host.example.com-error_log"
# CustomLog "logs/dummy-host.example.com-access_log" common
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.daixuan.com$ [OR] OR代表访问daixuan.com或者123.com
RewriteCond %{HTTP_HOST} ^www.123.com$
RewriteRule ^/(.*)$ http://www.test.com/$1 [R=301,L]
</IfModule>
<Directory /data/www/abc/>
AllowOverride AuthConfig
AuthName "Please input your name and password"
AuthType Basic
AuthUserFile /data/.htpasswd
require valid-user
</Directory>
</VirtualHost>

注：Apache301跳转使用的是rewrite模块
[root@daixuan ~]# apachectl -M
rewrite_module (shared) php
