有没有办法共享或重用 Apache 配置

我的 Apache 服务器上有以下目录结构

/var/www/domain.com/
    index.html
    site-1/
    site-2/
    .
    .
    .
    site-N/

每个站点使用以下配置文件，其中变量“port”、“site”和“hub”是唯一会改变的值

<IfModule mod_ssl.c>
    <VirtualHost *:443>
        # DOMAIN CONFIGURATION
        Define domain domain.dev

        ServerName ${domain}
        ServerAlias www.${domain}
        DocumentRoot /var/www/${domain}

        <Directory "/var/www/${domain}">
            AuthType Basic
            AuthName "${domain} Authentication"
            AuthUserFile /etc/apache2/.htpasswd
            Require valid-user
            <Files "manifest.json">
                Require all granted
            </Files>
        </Directory>

        SSLEngine on
        RewriteEngine on
        SSLProxyEngine on
        SSLProxyVerify none
        SSLProxyCheckPeerCN off
        SSLProxyCheckPeerName off
        SSLProxyCheckPeerExpire off

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        SSLCertificateFile /etc/letsencrypt/live/${domain}/cert.pem
        SSLCertificateKeyFile /etc/letsencrypt/live/${domain}/privkey.pem
        SSLCertificateChainFile /etc/letsencrypt/live/${domain}/fullchain.pem

        <FilesMatch "\.(cgi|shtml|phtml|php)$">
            SSLOptions +StdEnvVars
        </FilesMatch>

        <Directory /usr/lib/cgi-bin>
            SSLOptions +StdEnvVars
        </Directory>

        # SITE CONFIGURATION
        Define site site-1
        Define port 5001
        Define protocol https
        Define hub site-1-hub

        ProxyPassMatch "^/${site}/api/(.+)" "${protocol}://localhost:${port}/api/$1"
        ProxyPassReverse "/" "${protocol}://localhost:${port}/"

        ProxyPassMatch "^/${site}/${hub}/(.+)" "${protocol}://localhost:${port}/${hub}/$1"
        ProxyPassReverse "/" "${protocol}://localhost:${port}/${hub}"

        RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
        RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
        RewriteRule "^/${site}/(.+)" "wss://localhost:${port}/$1" [P]
    </VirtualHost>

有没有办法共享、重用或集中“域配置”和“站点配置”部分，这样我就不必在同一个域下的多个站点之间重复配置？如果是这样，我将能够对一个共享配置进行更改，该更改将应用​​于任何使用它的域或站点。

apache2ctl -S 输出

        VirtualHost configuration:
    *:80                   localhost (/etc/apache2/sites-enabled/000-default.conf:1)

以下是提供的解决方案的实际实现艾萨·约基宁（注：mod_macro模块需要通过sudo a2enmod macro命令行运行来启用）

/etc/apache2/sites-available/domain.dev.conf 内容：

<Macro Domain $domain>
    ServerName $domain
    ServerAlias www.$domain
    DocumentRoot /var/www/$domain

    # Basic authentication
    <Directory "/var/www/$domain">
        AuthType Basic
        AuthName "$domain Authentication"
        AuthUserFile /etc/apache2/.htpasswd
        Require valid-user
        <Files "manifest.json">
            Require all granted
        </Files>
    </Directory>

    RewriteEngine on
    
    SSLEngine on
    SSLProxyEngine on
    SSLProxyVerify none
    SSLProxyCheckPeerCN off
    SSLProxyCheckPeerName off
    SSLProxyCheckPeerExpire off

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    SSLCertificateFile /etc/letsencrypt/live/$domain/cert.pem
    SSLCertificateKeyFile /etc/letsencrypt/live/$domain/privkey.pem
    SSLCertificateChainFile /etc/letsencrypt/live/$domain/fullchain.pem

    <FilesMatch "\.(cgi|shtml|phtml|php)$">
        SSLOptions +StdEnvVars
    </FilesMatch>

    <Directory /usr/lib/cgi-bin>
        SSLOptions +StdEnvVars
    </Directory>
</Macro>

<Macro Site $site $port $protocol $hub>
    ProxyPassMatch "^/$site/api/(.+)" "$protocol://localhost:$port/api/$1"
    ProxyPassReverse "/" "$protocol://localhost:$port/"

    ProxyPassMatch "^/$site/$hub/(.+)" "$protocol://localhost:$port/$hub/$1"
    ProxyPassReverse "/" "$protocol://localhost:$port/$hub"

    RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
    RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
    RewriteRule "^/$site/(.+)" "wss://localhost:$port/$1" [P]
</Macro>

<IfModule mod_ssl.c>
    <VirtualHost *:443>
        Use Domain domain.dev

        Use Site site-1 5003 https site-1-hub
        Use Site site-2 5004 https site-2-hub
        .
        .
        .
        Use Site site-N 500N https site-N-hub
    </VirtualHost>
</IfModule>

Apache 模块 mod_macro可能正是您要找的。您可以定义一个宏：

<Macro MyProxySites $site $port $protocol $hub>
    ProxyPassMatch "^/$site/api/(.+)" "$protocol://localhost:$port/api/$1"
    ProxyPassReverse "/" "$protocol://localhost:$port/"

    ProxyPassMatch "^/$site/$hub/(.+)" "$protocol://localhost:$port/$hub/$1"
    ProxyPassReverse "/" "$protocol://localhost:$port/$hub"

    RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
    RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
    RewriteRule "^/$site/(.+)" "wss://localhost:$port/$1" [P]
</Macro>

然后在你的配置中多次使用它，例如

<IfModule mod_ssl.c>
    <VirtualHost *:443>
        ServerName example.com
        ServerAlias www.example.com
        DocumentRoot /var/www/example.com

        # . . .
        Use MyProxySites site-1 5001 https site-1-hub
        Use MyProxySites site-2 5002 https site-2-hub
    </VirtualHost>
    <VirtualHost *:443>
        ServerName example.net
        ServerAlias www.example.net
        DocumentRoot /var/www/example.net

        # . . .
        Use MyProxySites site-3 5003 https site-3-hub
        Use MyProxySites site-4 5004 https site-4-hub
    </VirtualHost>
</IfModule>

从您的问题来看很难说出您的确切目标，但如果每个站点的域名都会发生变化，并且一个域名只有一个代理，那么您也可以将其直接构建到宏中：

<Macro MyProxySites $domain $site $port $protocol $hub>
    <VirtualHost *:443>
        ServerName $domain
        ServerAlias www.$domain
        DocumentRoot /var/www/$domain

        ProxyPassMatch "^/$site/api/(.+)" "$protocol://localhost:$port/api/$1"
        ProxyPassReverse "/" "$protocol://localhost:$port/"

        ProxyPassMatch "^/$site/$hub/(.+)" "$protocol://localhost:$port/$hub/$1"
        ProxyPassReverse "/" "$protocol://localhost:$port/$hub"

        RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
        RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
        RewriteRule "^/$site/(.+)" "wss://localhost:$port/$1" [P]
    </VirtualHost>
</Macro>

Use MyProxySites example.com site-1 5001 https site-1-hub
Use MyProxySites example.net site-2 5002 https site-2-hub
Use MyProxySites example.org site-3 5003 https site-3-hub
