[ome-users] Getting an error "Apache/mod_perl is not properly configured" while installing OME Server.

Hi Curtis,
The mod_perl problem was resolved. In the httpd conf file, I have included this line LoadModule perl_module /usr/lib/httpd/modules/mod_perl.so.
But now I am getting problem in OMEIS module.
Please find the errors below,

Testing Apache configuration
  \__ mod_perl [SUCCESS].
  \__ omeis [FAILURE].


Errors executing task: OMEIS could not be reached.
Incorrect response from OMEIS at http://localhost/cgi-bin/omeis:
Error calling Initialization: Could not change working directory to /OME/OMEIS: Permission denied
System Error: Permission denied

See /var/tmp/OME/install/ApacheConfigTask.log for more details. at (eval 192) line 1

 at install.pl line 82
        main::run_tasks() called at install.pl line 266

Could you please help me to resolve this problem?

Thanks & Regards,
Sriram.

Hi Sriram,

Most likely, you just need to use the "Include" directive in your main Apache config file.

The installer probably inserted the proper lines into your /usr/local/apache2/conf/httpd.conf file, but for some reason they aren't being honored there. I think that file is a legacy file for Apache1 stuff -- usually for Apache2 there is nothing much in there.

As for where your actual main Apache config file is, look for a sites-available directory somewhere under /usr/local/apache2, I think.

I am not an expert on Apache so you might want to CC the list with any follow-up questions.

Hi Curtis,
Thanks for the email.
I have installed apache in /usr/local/apache2 manually.
I don't know where to include this reference for OME.
Could you please assist me in this?

Thanks in advance.


Thanks & Regards,
Sriram.

Hi Sriram,

According to the log, it's not that you don't have mod_perl installed, but rather that the /perl2 alias is not functioning -- hence the 404 Not Found. For whatever reason, it looks like the OME installer could not modify your Apache configuration successfully. It also looks like you installed your own version of Apache, so the config files are not where they would be in a default installation.

It looks like the OME installer has been updated since last time I used it, so I'm not 100% sure, but I believe you need to configure your Apache installation to include references to the appropriate /OME/conf/httpd2.*.conf files. Once you do that, and restart the web server, it should be able to find /perl2 successfully (you can test in your web browser). Then you can rerun the installer and it should pass the mod_perl test, assuming you actually have mod_perl installed.
