Apache で VirtualHost一覧を表示

久しぶりに触るたびに、忘れてる気がするのでメモ。

簡単なコマンド：

apachectl -S

VirtualHostのみを表示する場合：

apachectl -t -D DUMP_VHOSTS

すごく便利ですよね？Apache使いなら、当たり前なのだろうと思いつつも。

出力例： Redhat + SCL という環境なのでコマンドパスが特殊）

$ /opt/rh/httpd24/root/usr/sbin/apachectl -S
VirtualHost configuration:
 *:80                   is a NameVirtualHost
         default server aaa.bbb.ccc.ddd (/opt/rh/httpd24/root/etc/httpd/conf.d/000_serverip.conf:5)
         port 80 namevhost serviceone.domain.local (/opt/rh/httpd24/root/etc/httpd/conf.d/001_serviceone.conf:8)
         port 80 namevhost servicetwo.domain.local (/opt/rh/httpd24/root/etc/httpd/conf.d/002_servicetwo.conf:1)
ServerRoot: "/opt/rh/httpd24/root/etc/httpd"
Main DocumentRoot: "/opt/rh/httpd24/root/var/www/html"
Main ErrorLog: "/opt/rh/httpd24/root/etc/httpd/logs/error_log"
...
