Apache2 配置 - AWS Linux 2 上的虛擬主機 IP

/etc/httpd/conf.d/vhosts.conf:

<VirtualHost *:80>
   ServerAdmin admin@example.io
   DocumentRoot "/var/www/html/vhosts/main-repo-dir"
   ServerName example.io
   ErrorLog "logs/example.io-error_log"
   CustomLog "logs/example.io-access_log" common
</VirtualHost>

<VirtualHost *:80>
   ServerAdmin dev@example.io
   DocumentRoot "/var/www/html/vhosts/dev-repo-dir"
   ServerName dev.example.io
   ErrorLog "logs/dev.example.io-error_log"
   CustomLog "logs/dev.example.io-access_log" common
</VirtualHost>

這可行，但是當我用 url 替換星號時，DocumentRoot預設為/var/www/html：

<VirtualHost example.io:80>
   ServerAdmin admin@example.io
   DocumentRoot "/var/www/html/vhosts/main-repo-dir"
   ServerName example.io
   ErrorLog "logs/example.io-error_log"
   CustomLog "logs/example.io-access_log" common
</VirtualHost>

<VirtualHost dev.example.io:80>
   ServerAdmin dev@example.io
   DocumentRoot "/var/www/html/vhosts/dev-repo-dir"
   ServerName dev.example.io
   ErrorLog "logs/dev.example.io-error_log"
   CustomLog "logs/dev.example.io-access_log" common
</VirtualHost>

/etc/hosts:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost6 localhost6.localdomain6

127.0.0.1   example.io
127.0.0.1   dev.example.io

我可以使用星號，我只是想了解為什麼在這種情況下必須這樣做。

該部分僅定義可以到達該虛擬主機的 ip。在這種情況下，這<VirtualHost *:80>意味著 apache 將讓所有網路介面訪問該虛擬主機。我認為您遇到的行為是您正在進入預設文件根目錄，因為您設置的虛擬主機都沒有打開
