阿帕奇到PSGI代理通过Unix域套接字 [英] Apache-to-PSGI proxy over a Unix domain socket
问题描述
我们有相同的机器上运行，因此需要其PSGI服务器到唯一的端口运行PSGI应用的许多（隔离）的安装。这是不到一个资源/管理的角度看理想，但在同一台机器上运行时，它也需要（尚未不可测量的，可能微不足道）TCP / IP的开销当一个Unix域套接字似乎是更明智的选择
We have many (isolated) installations of a PSGI app that run on the same machine and thus require their PSGI servers to run on unique ports. This is less than ideal from a resource/management perspective, but it also requires the (yet-unmeasured and possibly insignificant) "overhead" of TCP/IP when a Unix domain socket would seem to be more obvious choice when running on the same machine.
幸运的是，应用程序下普拉克的HTTP接口（通过mod_proxy的的的ProxyPass来自Apache代理）的作品，但不幸的是，它的FastCGI接口下打破（见：的可PSGI应用程式下普拉克::处理器:: FCGI fork（）的？）。
Fortunately, the app works under Plack's HTTP interface (proxied from Apache via mod_proxy's "ProxyPass"), but unfortunately, it breaks under the FastCGI interface (see: Can PSGI apps fork() under Plack::Handler::FCGI?).
除此之外的mod_fastcgi的FastCgiExternalServer（或修补的mod_proxy这个未经测试，用户贡献的补丁程序：<一href=\"http://mail-archives.apache.org/mod_mbox/httpd-dev/201207.mbox/%3C20120731200351.GB11038@gmail.com%3E\" rel=\"nofollow\">http://mail-archives.apache.org/mod_mbox/httpd-dev/201207.mbox/%3C20120731200351.GB11038@gmail.com%3E),有没有什么办法来代理阿帕奇连接的通过Unix域套接字的一个PSGI应用程序？
Other than mod_fastcgi's FastCgiExternalServer (or patching mod_proxy with this untested, user-contributed patch: http://mail-archives.apache.org/mod_mbox/httpd-dev/201207.mbox/%3C20120731200351.GB11038@gmail.com%3E), is there any way to proxy Apache connections over a Unix domain socket to a PSGI app?
推荐答案
有
There is mod_proxy_fdpass which allows Apache to proxy to domain sockets, although I haven't tried it.
我个人推荐使用的标准各-APP-上一个端口的安排，除非你可以测量的开销是值得做标新立异的。
I was personally recommend using the standard each-app-on-a-port arrangement, unless you can measure the overhead to be worth doing something unconventional for.
您还可以使用每个应用程序一个私有到该服务器的IP地址，并让他们在自己的私人IP地址端口80上运行的所有的选项。
You also have the option of using one private-to-the-server IP address per app, and having them all run on port 80 on their private IPs.
