Internal server error

gokahd · 02-24-2009, 02:54 AM

Hello, i have successfully installed mysql, openssl, apache, qmail,
vpopmail and qmailadmin without any errors. when i type
http://localhost/cgi-bin/qmailadmin at the browser, i get this error:

internal server error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, postmaster@gokahgh.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

I am using FC5. I have googled for sometime now but cannot fix this problem

Any help is deeply appreciated. Thanks

check the path of of your URL if it is valid on the apache configuration.

Make sure that the files you've added in the cgi-bin directory are executable.
Also looking at error_log could give you a hint about the problem

Please i am a newbie setting up a mail server.
i have googled to search for the log file of the server i am creating but to no avail. Please can you tell me where the log file of the mail server is residing? This will help me to detect where the error is and google for the solution

secondly i don't know how to check if my cgi-bin is executable.
Thanks for any reply.

Before anything else you should check if this isn't a selinux problem.
Run

Code:

setenforce 0

to disable it and check if it works.
No regarding your question:

You didn't say how you've installed apache. If you've installed it from rpm, then the apache config file should be in /etc/httpd/conf/httpd.conf. So run

Code:

grep ErrorLog  /etc/httpd/conf/httpd.conf

to find the location of the error_log.

It depends from where you installed qmailadmin. You can post here how you've installed it, or you can use:

Code:

updatedb
locate cgi-bin/qmailadmin

to find the full path to qmailadmin. After that, run:

Code:

chmod +x /full/path/to/cgi-bin/qmailadmin

to make it executable.

gokahd · 02-25-2009, 02:56 AM

Sorry i could'nt reply early enough. we closed from work and i went home.
I am very grateful for all your responses.

I disabled SElinux while installing the FC5 operating system.

I also installed the .tar.gz file of apache version 1.3.37

I have located the path to cgi-bin/qmailadmin it is at /usr/local/apache/cgi-bin/qmailadmin

I have also chmod + x /usr/local/apache/cgi-bin/qmailadmin and went to the browser and typed http://localhost/cgi-bin/qmailadmin but still had the internal server error.

Is there anything else i could do to solve this. Thanks

So you have installed apache from source using the default prefix: /usr/local/apache. That means that the log files are in //usr/local/apache/logs. You can

Code:

tail /usr/local/apache/logs/error_log

to see the last lines of error_log

gokahd · 02-25-2009, 04:15 AM

Hello when i do tail /usr/local/apache/logs/error_log, i get the following errors:

How did you install mysql? Because qmailadmin cannot find a needed mysql library
Can you locate the missing file libmysqlclient.so.15?

gokahd · 02-25-2009, 04:47 AM

Yes i can locate libmysqlclient.so.15. it is at

/usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient.so.15

it is also at:

/usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient.so.15.0.0

bathory · 02-25-2009, 04:50 AM

You have to add /usr/local/mysql-5.0.45-linux-i686-glibc23/lib in /etc/ld.so.conf so mysql libraries can be found and then run

Code:

ldconfig

After that check again if the cgi works

gokahd · 02-25-2009, 05:05 AM

I did
vi /etc/ld.so.conf
and added
/usr/local/mysql-5.0.45-linux-i686-glibc23/lib to /etc/ld.so.conf
and did
ldconfig and had
ldconfig: /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient_r.so.15 is not a symbolic link

ldconfig: /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient.so.15 is not a symbolic link

ldconfig: /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libndbclient.so.2 is not a symbolic link

and typed http://localhost/cgi-bin/qmailadmin at the browser but still had the internal server error

bathory · 02-25-2009, 05:37 AM

The ldconfig warnings are harmless. If you want, I can tell you how to get rid of them.
What's in error_log now?

gokahd · 02-25-2009, 05:43 AM

this is what is in the error_log now:

qmailadmin: error while loading shared libraries: libmysqlclient.so.15: cannot open shared object file: No such file or directory

Thank you!

bathory · 02-25-2009, 06:02 AM

Run:

Code:

rm /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient.so.15
rm /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient_r.so.15
ln -s /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient.so.15.0.0 /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient.so.15
ln -s /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient_r.so.15.0.0 /usr/local/mysql-5.0.45-linux-i686-glibc23/lib/libmysqlclient_r.so

I don't have the libndbclient.so.2 library but the procedure is the same. Delete the file with the .2 extension and create a symlink to .2.0.0 (or whatever its complete name is).
After that run ldconfig again, restart apache and look at the error_log
