使用ProxyPass页面而不是图像

标签: apache proxy mod-jk ajp proxypass

由于horrible, horrible errors,我们改变了将Apache连接到Tomcat的方式。我们使用mod_jk

JkMount /path ajp13

现在我们正在使用mod_proxy_ajp

ProxyPass /path ajp://localhost:8009/path
ProxyPassReverse /path ajp://localhost:8009/path

但是,有JkMount提供的功能,但ProxyPass没有:能够选择文件类型。这使得代理html文件成为可能,但不能代理图像 - 换句话说,让漂亮的快速Apache服务于静态的东西,并仅仅为动态的东西使用缓慢的Tomcat。

JkMount /*.html ajp13

有没有办法用ProxyPass实现这一目标?可能使用周围的<Location>指令或类似的东西?

使用ProxyPassMatch

ProxyPassMatch ^/(path/.*\.html)$ ajp://localhost:8009/$1

不是您的问题,但需要注意使用此配置。使用apache mod_proxy连接到tomcat时,我的错误日志显示在适度负载下丢弃的连接。 将此添加到httpd.conf解决了我的问题。

SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1

kmkaplan的帖子是正确的答案,但它给了我错误:

Syntax error on line 32 of .../httpd-vhosts.conf:
ProxyPass Unable to parse URL

当我将指令更改为:

时,它有效
ProxyPathMatch ^/(path/.*\.html)$ ajp://localhost:8009/$1

我只能假设将$1放在端口号8009旁边,这让人感到困惑。

我们使用以下内容让Apache提供图像并设置合理的过期标题:

<Virtualhost *:80>
    ServerName domain.com
    ServerAlias *.domain.com

    Alias /img/ /var/www/domain/img/
    <Directory /var/www/domain/img/>
        ExpiresActive On
        ExpiresByType image/gif "access plus 1 months"
        ExpiresByType image/jpg "access plus 1 months"
        ExpiresByType image/jpeg "access plus 1 months"
        ExpiresByType image/png "access plus 1 months"
        ExpiresByType image/x-icon "access plus 1 months"
        ExpiresByType image/ico "access plus 1 months"
        # This will prevent apache from having to check for a .htaccess file on each request.
        AllowOverride None
        # Allow symlinks. Otherwise, apache will make a separate call on each filename to ensure it is not a symlink.
        Options +FollowSymLinks -SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ProxyRequests Off
    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    # Prevent domain.com/img from being served by Tomcat
    ProxyPass /img !

    # Pass all other requests to Tomcat
    ProxyPass / ajp://localhost:8009/

    # 1. Note that usually no ProxyPassReverse directive is necessary. The AJP request includes
    #    the original host header given to the proxy, and the application server can be expected to
    #    generate self-referential headers relative to this host, so no rewriting is necessary. 
    # 2. If you still want to use it, read this first:
    #    http://www.humboldt.co.uk/2009/02/the-mystery-of-proxypassreverse.html
    # ProxyPassReverse / http://domain.com/
</Virtualhost>

但是,正如您所看到的,我们将图像存储在Tomcat应用程序之外。我不知道它是否适用于应用程序内的图像。
