Re: install mod_fastcgi to apache

Janus Troelsen — 2013-04-18T08:05:52

Why are you compiling yourself? Are you not using a distro with
prepackaged binaries?

Anyway, mod_fastcgi has been pretty much deprecated in favor of mod_fcgid.

If you use Apache 2.4+ you don't even need any mods, because
mod_proxy_fcgi was added. It doesn't work for UNIX sockets, though. I
think the mod_proxy_fcgi approach is the nicest, because process
spawning doesn't belong in Apache anyway. For example, I am using
Apache 2.4 with PHP-FPM (which does the spawning).

On Ubuntu, you can just apt-get install libapache2-mod-fcgid, and then
"a2enmod fcgid".

install mod_fastcgi to apache

Jia, Yicheng — 2013-04-17T22:40:38

Hi Folks,

I am new to fastcgi and today just downloaded and compiled the fastcgi module 2.4.0, by doing

1.       configure

2.       make & make install

I notice both "libcgi++.a" and "libcgi.a" are copied to "/usr/local/lib" directory after installation.


Now I want to add the module statically to my apache 2.2.6 package, so I can build a new apache server with mod_fastcgi statically linked in, however I couldn't find a proper way to do it. By looking at the installation manual, I go to <apache_dir> and do "./configure --activate-module=src/modules/fcgi-2.4.0/libfastcgi.a" but it complains no such command option.



Can anyone help me? Thanks!


Best Regards!
Tony

Re: Supress error 500 by baiduspider

Thomas H Bowden Jr — 2013-04-07T18:20:20

In the past , when I have had similar problems there are two ways that i fixed it:

1) Increased the timeout on response (premise being that it was Apache and not fastcgi that terminated message before completion).

2) set the socket to unbuffered output (premise being that application was outputting line without a final \r\n… or somehow hadn't actually flushed the buffer in time.

Well, my logs are analyzed by OSSEC, so I have to patch either OSSEC
or mod_fastcgi anyway.

OSSEC parses all of my access.log's and reports things like status
500. So I need to get rid of it (after all it's not really the server
problem it's just the client killing the socket). And I want to keep a
record for this in error.log just in case (it isn't monitored by
OSSEC).

Here is what I have so far:

--- mod_fastcgi.c.orig  2013-04-06 12:33:07.747545365 +0300
+++ mod_fastcgi.c       2013-04-06 12:37:20.973544222 +0300
< at >< at > -2679,8 +2679,13 < at >< at >
     }

     /* Process the fastcgi-script request */
-    if ((ret = do_work(r, fr)) != OK)
+    if ((ret = do_work(r, fr)) != OK) {
+        if (ret == 53) {
+            ap_log_rerror(FCGI_LOG_ERR_NOERRNO, r, "FastCGI:
Suppressed error 53");
+            return OK;
+        }
         return ret;
+    }

     /* Special case redirects */
     ret = post_process_for_redirects(r, fr);

It doesn't work. Can you help me with this patch please?

Supress error 500 by baiduspider

Ross — 2013-04-07T05:26:23

Hello.

Since recent upgrade of mod_fastcgi I keep getting this:

FastCGI: client stopped connection before send body completed
FastCGI: client stopped connection before send body completed
Handler for fastcgi-script returned invalid result code 53

This is caused by baiduspider and ancient IEs. It seems that they
close the socket before server could send the data. This result in
error 500.

Could you please help me suppress this error (I don't want to see it
in access.log as I get an email for every such an error) while still
logging the event in error.log?

Re: Getting request headers (sent by the browser)

Paul Brown — 2013-03-18T09:39:23

Hi,
In the Java implementation, they get put into the System properties and 
appear in uppercase with underscores. For example:

REQUEST_METHOD
CONTENT_TYPE

Re: Getting request headers (sent by the browser)

Rob Lemley — 2013-03-16T23:11:30

I don't know how it's exposed in the java interface, but in the c++ interface, the headers are available as CGI environment variables in the char** FCGX_Request.envp variable.  As I recall, all of the HTTP header names in the table will have "HTTP_" prepended, and all dashes (-) will appear as underscores  (_) in the FCGX_Request.envp table.

Getting request headers (sent by the browser)

Udo Schroeter — 2013-03-16T16:21:36

Hey all,

I'm using the Java reference implementation from fastcgi.com. What I can't
figure out (neither from the white paper nor from looking at the code
itself) is:

How can I get at the actual header variables sent by the browser to the
webserver? From what I can tell they're not in the input stream...

I'm sorry if I missed something obvious, but I'm stuck and a little hint
would be greatly appreciated.

Thanks,

Udo

Fastcgi issues

2013-03-05T11:14:54

Hi all,

Appologies if tis is not the right mailing list – most of the communications I’ve seen have been to do with C programming...

... but can anyone help with memory / execution errors when using PHP on a server running as FASTCGI. (or recommend another source of help).

Session Management

Abc Def — 2013-03-05T06:39:12

Hi,

I am new in FastCGI programming using C. I am using nginx Web
 Server. I have been trying to store session for a user as he logs in, 
but apart from using cookies I am not able to find any other way. I 
tried googling regarding this issue where I found some links talking 
about session affinity. Can anyone tell me how will session affinity be 
implemented? The basic problem which I was facing is that if I use 
socket file descriptor returned by OS_Accept or try to store information
 in some environment variable then that information gets lost in next 
call to FCGX_Accept.


Any kind of help is most welcome.

Hi All,

I am new to FastCGI and working on very basic POC application using it.

I downloaded source *fcgi-2.4.1-SNAP-0311112127* and tried to compile it. I
could compile *libfcgi* but not able to load

cgifcgi.dsp in VS 10.

I am getting error as :

*fcgi-2.4.1-SNAP-0311112127\Win32\cgifcgi.dsp : error  : Project upgrade

Can anybody please let me know where I can get updated project file or some
pointers in this regard.

Thanks in advance.

Re: can a httpd fcgi module start sending generatedresponse while the request message body is still beingtransmitted to the app?

David Birmbaum — 2013-01-21T18:23:21

The mod_fastcgi library has an internal buffer that it uses to improve efficiency back to the HTTP process.  You can tune it if you like; I would often crank it way up so the application could dump the whole output without having to wait for the client to receive.

David.

I agree with Jay.

My web-server (by force) has always been apache.  I use perl scripts for anything that is not c++.  In there I have to unbuffer stdin/stdout  ( $|=1).

Jay Sprenkle — 2013-01-20T21:42:48

Wouldn't the web server module control that behavior?
Seems like fastcgi doesn't have any control over what happens to the data
after it's written to the pipe.

2013-01-20T19:33:58

Hi all!

I was trying to send a (chunked-encoding) answer that was being
generated after each chunk of the POST-ed message body was being
received. I tried with both mod_fcgid and mod_proxy_fcgi and
both seem to buffer output until all POSTed message body was
delivered to the application
(they just passed back what was generated after the headers were
accepted, but not after the body started coming. In fact, mod_fcgid
kept crashing if much of the response was building up)

So is this the typical way httpd's fcgi modules handle communication
with a fcgi content generator? won't alternate write/read over
the STDOUT_FILENO that connect the server with the app? (i.e. treat
it as a bidirectinal pipe or open another unidirectional pair?)
If so, have you heard of any better httpd module that can solve this?

any answer/idea or pointer will be greatly appreciated!

best regards

Tand Read

Re: FASTCGI - How to Debug C++ fastfcgi

Jay Sprenkle — 2013-01-08T18:05:38

You can approach this in several ways:

1. Write an application that calls your fastcgi process and tests it.
2. Use load testing and automation software to do this.

If you want to try out a free testing package this one looks like it might
work for you:
http://www.pushtotest.com/web-testing-with-selenium-pushtotest
You could install the proxy and record an interaction with your web page.
You can then use the recorded script to load test and test the functions of
your fastcgi app.

I am not affiliated with them and can't speak from experience about how
good selenium is.
I've been told second hand that it works well.
