LAMP构架-域名跳转

Posted 2020-10-26

域名跳转

将之前使用的域名转向新域名，例如起点小说网最早使用的是www.cmfu.com，现在改成www.qidian.com；
由于老用户的存在只记住了www.cmfu.com，现在想输入老域名cmfu直接跳转到qidian.com上；

修改httpd-vhosts.conf配置文件

vim /usr/local/apache2.4/conf/extra/httpd-vhosts.conf

<VirtualHost *:80>
    DocumentRoot "/data/wwwroot/szl.com"
    ServerName szl.com
    ServerAlias www.example.com www.szl.com
    <IfModule mod_rewrite.c>                                        //需要mod_rewrite模块支持
      RewriteEngine on                                                    //打开rewrite功能
      RewriteCond %{HTTP_HOST} !^szl.com$                  //定义rewrite的条件，如果主机名（域名）不是szl.com，那就满足条件
      RewriteRule ^/(.*)$ http://szl.com/$1 [R=301,L]        //定义rewrite规则，满足上面的条件，那么这条就生效
    </IfModule>
    ErrorLog "logs/szl.com-error_log"
    CustomLog "logs/szl.com-access_log" common
</VirtualHost>

生效配置

/usr/local/apache2.4/bin/apachectl -t
/usr/local/apache2.4/bin/apachectl graceful

查询rewrite是否加载

/usr/local/apache2.4/bin/apachectl -M |grep rewrite

加载rewrite模块

vim /usr/local/apache2.4/conf/httpd.conf

取消注释LoadModule rewrite_module modules/mod_rewrite.so

再次生效配置

/usr/local/apache2.4/bin/apachectl -t
/usr/local/apache2.4/bin/apachectl graceful

测试

使用IE浏览器测试，否则其他浏览器有可能在szl.com前面自动添加www

www.example.com/admin.php 成功跳转为http://szl.com/admin.php

服务器测试：

[[email protected] ~]# curl -x192.168.188.2:80 www.example.com/admin.php -I
HTTP/1.1 301 Moved Permanently
Date: Fri, 02 Mar 2018 10:10:25 GMT
Server: Apache/2.4.29 (Unix) PHP/5.6.30
Location: http://szl.com/admin.php
Content-Type: text/html; charset=iso-8859-1
[[email protected] ~]#

访问www.example.com 无论后缀的文件目录有多少一样跳转到szl.com下

[[email protected] ~]# curl -x192.168.188.2:80 www.example.com/1dfkdsjldfj/ldsjfaos/sdlfs.php -I
HTTP/1.1 301 Moved Permanently

Location: http://szl.com/1dfkdsjldfj/ldsjfaos/sdlfs.php
Content-Type: text/html; charset=iso-8859-1
[[email protected] ~]#

访问szl.com，不存在的文件目录错误将显示404

[[email protected] ~]# curl -x192.168.188.2:80 szl.com/1dfkdsjldfj/lds -I
HTTP/1.1 404 Not Found

访问szl.com，存在的文件目录错误将显示200

[[email protected] ~]# curl -x192.168.188.2:80 szl.com/admin.php -I
HTTP/1.1 200 OK
