最近買了 domain，比如 xxxx.com
但我們可能想設個人網站為 personal.xxxx.com，部落格網站為 blog.xxxx.com
然而這兩個網站都對應到同一台主機，這時候我們就需要 virtual host的 功能了。

複製/etc/apache2/sites-available/000-default.conf
<VirtualHost *:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. #ServerName www.example.com ServerAdmin webmaster@localhost DocumentRoot /var/www/html # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/error.log CustomLog ${APACHE_LOG_DIR}/access.log combined # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf </VirtualHost> -
創建 blog.conf，並貼上剛剛複製的內容，但更改以下內容 ServerName blog.xxxx.com ServerAlias www.blog.xxxx.com DocumentRoot /var/www/html/blog # 對應到 blog 的根目錄資料夾
-
啟用虛擬網站 sudo a2ensite blog.conf
-
重新載入 apache 設定 sudo service apache2 reload
-
記得要設定DNS，把 blog.xxxx.com 指向你的機器IP
ps. 如果要停用設定的 virtual host sudo a2dissite blog.conf sudo service apache2 reload
