No logging from Apache/2.2.15 CentOS 6

[squareborg]

Hi, Just been trying to use this module. Having an issue not getting any output from it.

apachectl -V | grep version
Server version: Apache/2.2.15 (Unix)

apachectl -D DUMP_MODULES | grep dump
Syntax OK
dumpost_module (shared)

I then have this in /etc/httpd/conf/httpd.conf

DumpPostLogFile /var/log/httpd/post.log

I then make a post request which is logged by apache

[root@localhost mod_dumpost]# tail /var/www/vhosts/website1.com/logs/access_log | grep POST
10.211.55.2 - - [17/Dec/2015:08:16:17 +0000] "POST /wp-login.php?action=lostpassword HTTP/1.0" 200 3415 "http://website1.com/wp-login.php?action=lostpassword" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36"

But nothing is ever logged in var/log/httpd/post.log

Any help?

Cheers.

Can you make sure the user running web service have permission to the file ?

Hi, I have the same issue. No logfile is ever created. Log location is /tmp, which should be writeable to everyone. I'm on Ubuntu 14.04 here.

[danghvu]

Did you make sure LogLevel of at least Info ?
Try not to use DumpPostLogFile and see if it's appearing in the normal log first.

[squareborg]

Hey @danghvu I have set log level to info and tried without DumpPostLogFile and nothing gets logged in error_log or DumpPostLogFile.

This is a server installed with Plesk so maybe something going on there. I will try a straight CentOS 6 vm.

[squareborg]

Okay after running in a stock CentOS 6.7 vm I can get it too log to error_Log but still cannot get it to log to a file.

It did not work to error_log on Plesk as LogLevel info was getting overidden in per site apache config, apologies for that did not think at the time!

However I am trying my hand a GDB to see why its not logging to file. I have checked permissions and my testing means i'm running httpd as root anyway.

[danghvu]

Can you grep error_log for mod_dumpost, if there is a problem with log file it will give some error messages:

mod_dumpost: unable to open the log file: or mod_dumpost: error while writing to log

[squareborg]

Sorry been a while, logs to error log but nothing in the DumpPostLogFile file.

[danghvu]

Seems like the option does not get populated, where did you specify the logfile option ?

[squareborg]

/etc/httpd/conf/httpd.conf

[danghvu]

Can you paste the content of that file ? Are you sure that was the file being used by your server ?

[dr01]

Hi, I have the same issue. Server is httpd v2.2.15 on CentOS 6.6.

These are the relevant directives in my /etc/httpd/conf/httpd.conf:

DumpPostMaxSize 5000000 
DumpPostHeaderAdd Cookie Content-Type
DumpPostLogFile /var/log/httpd/dumpost.log

The file /var/log/httpd/dumpost.log is never created. Instead, mod_dumpost entries are logged into /var/log/httpd/error_log, but they all look like this:

[Thu May 26 15:42:49 2016] [warn] [client 66.77.88.99] mod_dumpost: body limit reach

I've tried to change the LogLevel from warn to info (even if this would not be necessary as DumpPostLogFile is specified), but after this change no more mod_dumpost entries get logged in error_log.

[danghvu]

Are you sure your http server having the permission to write to that file ? I would try to make that file first,
chmod 777 /var/log/httpd/dumpost.log and see if it works

As note for debugging, always set your loglevel to (debug) so you will have complete full log of whats going on. Also as @danghvu pointed out you have to chmod the file, but also, the folder containing it
chmod 0777 /var/log/apache2/dumpit/
if your logfile is for example /var/log/apache2/dumpit/post.log
