Apache2 Web服务器常用配置

虚拟主机基本配置

<VirtualHost *:80>
    ServerName subdomain.example.com
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/subdomain.example.com
    ErrorLog ${APACHE_LOG_DIR}/error-subdomain.example.com.log
    CustomLog ${APACHE_LOG_DIR}/access-subdomain.example.com.log combined
    <Directory />
        Options FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

HTTP访问跳转到HTTPS访问

<VirtualHost *:80>
  ServerAlias  example.com
  RewriteEngine On
  RewriteRule ^(.*) https://www.example.com [R=301,L]
</VirtualHost>

301跳转，访问域名AAAA.com重定向到BBBB.com

<VirtualHost *:80>
ServerName subdomain.AAAA.com
RewriteEngine On
RewriteRule ^(.*)$ https://subdomain.BBBB.com$1 [R=301,L]
</VirtualHost>
<VirtualHost *:443>
SSLEngine On
SSLCertificateFile      /etc/letsencrypt/live/AAAA.com/fullchain.pem 
SSLCertificateKeyFile   /etc/letsencrypt/live/AAAA.com/privkey.pem 
SSLCertificateChainFile /etc/letsencrypt/live/AAAA.com/chain.pem 
ServerName subdomain.AAAA.com
RewriteEngine On
RewriteRule ^(.*)$ https://subdomain.BBBB.com$1 [R=301,L]
</VirtualHost>

反向代理

<VirtualHost *:443>
  ServerName example.com
  DocumentRoot /opt/example/
  RewriteEngine On
  RewriteCond %{HTTP:Connection} Upgrade [NC]
  RewriteCond %{HTTP:Upgrade} websocket [NC]
  RewriteRule /(.*) ws://127.0.0.1:8080/$1 [P,L]
  <Directory />
    Require all granted
  </Directory>
  ProxyRequests On
  <proxy *>
    Order deny,allow
    Allow from all
  </proxy>
  ProxyPass / http://127.0.0.1:8080/
  ProxyPassReverse / http://127.0.0.1:8080/
</VirtualHost>
