域名跳轉
-
需求，將123.com域名跳轉到www.123.com，配置如下： <VirtulHost :80> DocumentRoot "/data/wwwroot/www.123.com ServerName www.123.com ServerAlias 123.com <IfModule mod_rewrite.c> #需要mod_rewrite模組支援 RewriteEngine on #開啟rewrite功能 RewriteCond %{HTTP_HOST}!^111.com$ #定義rewrite的條件，主機名（域名）不是111.com滿足條件，$表示結尾，不然只要包括111.com也是滿足條件 RewriteRule ^(.
)$http://www.123.com/$1 [R=301,L] #定義rewrite規則，當滿足上面的條件時，這條規則才會執行 </IfModule> </VirtulHost> -
/usr/local/apache2.4/bin/apachectl -M | grep -i rewrite #若無該模組，需要編輯配置檔案httpd.conf，刪除rewrite_module(shared)前面的#
-
curl -x 127.0.0.1:80 -I 123.com #狀態碼為301
-
權重
-
seo搜尋引擎優化
-
301重定向
主要是利用搜索引擎的方法將網站原有的權重作域名跳轉到另一個網站中，使其權重不變
[root@localhost ~]# vi /usr/local/apache2.4/conf/extra/httpd-vhosts.conf 31 <VirtualHost *:80> 32 DocumentRoot "/data/wwwroot/111.com" 33 ServerName 111.com 34 ServerAlias www.example.com 35 # <Directory /data/wwwroot/111.com> 36 # <FilesMatch user.php> 37 # AllowOverride AuthConfig 38 # AuthName "111.com user auth" 39 # AuthType Basic 40 # AuthUserFile /data/.htpasswd 41 # require valid-user 42 # </FilesMatch> 43 # </Directory> 44 <IfModule mod_rewrite.c> 45 RewriteEngine on 46 RewriteCond %{HTTP_HOST} !^www.123.com$ 47 RewriteRule ^/(.*)$ http://www.123.com/$1 [R=301,L] 48 </IfModule> 49 ErrorLog "logs/111.com-error_log" 50 CustomLog "logs/111.com-access_log" common 51 </VirtualHost>
，^/(.*)$指域名後面的部分，$1指前面第一個括號，若有指定則新增/$2/$3 永久重定則要定義301狀態碼，L表示指跳一次 302表示臨時重定向，但搜尋引擎則不會把原來的重定向降低
[root@localhost ~]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@localhost ~]# /usr/local/apache2.4/bin/apachectl graceful
檢查模組
[root@localhost ~]# /usr/local/apache2.4/bin/apachectl -M | grep rewrite
[root@localhost ~]# vi /usr/local/apache2.4/conf/httpd.conf
144 #LoadModule vhost_alias_module modules/mod_vhost_alias.so

146 LoadModule dir_module modules/mod_dir.so
147 #LoadModule actions_module modules/mod_actions.so

153 #LoadModule php7_module modules/libphp7.so
154
155 <IfModule unixd_module>
156 #
157 # If you wish httpd to run as a different user or group, you must run
158 # httpd as root initially and it will switch.

將151行LoadModule rewrite_module modules/mod_rewrite.so的註釋去掉
