You need to call <code>FCGI_Accept</code> in the <code>while</code> loop:

<pre><code>while(FCGI_Accept() &gt;= 0)
</code></pre>

You have <code>FCGI_Accept &gt;= 0</code> in your code. I think that results in the address of the <code>FCGI_Accept</code> function being compared to <code>0</code>. Since the function exists, the comparison is never false, but the function is not being invoked.

blocks|key|316443|text|在您的应用程序正确处理fastcgi-request之后，您需要注意启动应用程序。nginx永远不会自己产生fcgi进程，所以你需要一个守护进程来处理它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|316444|我推荐使用uwsgi来管理fcgi进程。它能够产生准备好输入的工作进程，并在它们死亡时重新启动它们。它具有高度的可配置性，易于安装和使用。|316445|http://uwsgi-docs.readthedocs.org/en/latest/|offset|length|316446|下面是我的配置：|316447|[uwsgi]

After your application handles fastcgi-requests correctly, you need to take care of starting the application. nginx will never spawn fcgi processes itself, so you need a daemon taking care of that.

I recommend using uwsgi for managing fcgi processes. It is capable of spawning worker-processes that are ready for input, and restarting them when they die. It is highly configurable and easy to install and use.

<a href="http://uwsgi-docs.readthedocs.org/en/latest/" rel="nofollow noreferrer">http://uwsgi-docs.readthedocs.org/en/latest/</a>

Here is my config:

<pre><code>[uwsgi]
fastcgi-socket = /var/run/apc.sock
protocol = fastcgi
worker-exec = /home/app/src/apc.bin
spooler = /home/app/spooler/
processes = 15
enable-threads = true
master = true
chdir = /home/app/
chmod-socket = 777
</code></pre>

This integrates nicely as systemd service, but can also run without.

I am attempting to run a fastcgi app written in C language behind the Nginx web server. The web browser never finishes loading and the response never completes. I am not sure how to approach it and debug. Any insight would be appreciated.

The hello world application was taken from fastcgi.com and simplified to look like this: 

<pre><code>#include "fcgi_stdio.h"
#include &lt;stdlib.h&gt;

int main(void)
{

 while(FCGI_Accept &gt;= 0)
 {
 printf("Content-type: text/html\r\nStatus: 200 OK\r\n\r\n");

 }

 return 0;
}
</code></pre>

Output executable is executed with either one of:

<blockquote>
 cgi-fcgi -connect 127.0.0.1:9000 a.out
</blockquote>

or

<blockquote>
 spawn-fcgi -a120.0.0.1 -p9000 -n ./a.out
</blockquote>

Nginx configuration is:

<pre><code>server {
 listen 80;
 server_name _;

 location / {
 # host and port to fastcgi server
 root /home/user/www;
 index index.html;

 fastcgi_pass 127.0.0.1:9000;
 }
}
</code></pre>
