域名跳轉

需求，將123.com域名跳轉到www.123.com，配置以下： <VirtulHost :80> DocumentRoot "/data/wwwroot/www.123.com ServerName www.123.com ServerAlias 123.com <IfModule mod_rewrite.c> #須要mod_rewrite模塊支持 RewriteEngine on #打開rewrite功能 RewriteCond %{HTTP_HOST}!^111.com$ #定義rewrite的條件，主機名（域名）不是111.com知足條件，$表示結尾，否則只要包括111.com也是知足條件 RewriteRule ^(.)$http://www.123.com/$1 [R=301,L] #定義rewrite規則，當知足上面的條件時，這條規則纔會執行 </IfModule> </VirtulHost>html
/usr/local/apache2.4/bin/apachectl -M | grep -i rewrite #若無該模塊，須要編輯配置文件httpd.conf，刪除rewrite_module(shared)前面的#web
curl -x 127.0.0.1:80 -I 123.com #狀態碼爲301apache
權重瀏覽器
seo搜索引擎優化php7
301重定向ssh

主要是利用搜索引擎的方法將網站原有的權重做域名跳轉到另外一個網站中，使其權重不變curl

[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，如有指定則添加/$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，但搜索引擎則不會把原來的重定向下降tcp

[root@localhost ~]# /usr/local/apache2.4/bin/apachectl -t
Syntax OK
[root@localhost ~]# /usr/local/apache2.4/bin/apachectl graceful

檢查模塊ide

[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
    145 #LoadModule negotiation_module modules/mod_negotiation.so
    146 LoadModule dir_module modules/mod_dir.so
    147 #LoadModule actions_module modules/mod_actions.so
    148 #LoadModule speling_module modules/mod_speling.so
    149 #LoadModule userdir_module modules/mod_userdir.so
    150 LoadModule alias_module modules/mod_alias.so
    151 #LoadModule rewrite_module modules/mod_rewrite.so
    152 LoadModule php5_module        modules/libphp5.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.
    159 #

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