[ome-users] Update Installation problems - Ubuntu

[Matthias Pigerl]

Hi guys!

After some time I would like to give you a quick update of all my 
installation problems with Ubuntu and OME.
(Kernel 2.6.12 - perl 5.8.7, mod_perl v 2.0.2 postgreSQL v.8.0.3 Apache2 
- OME 2.4.0)

But still I'm not very happy - I'm going to try the OME development 
versions from cvs or an other Linux distribution. Because with the 
combination above there are too many problems.

OK Step by Step:
If s.o. wants to start with the instructions at 
http://www.openmicroscopy.org/install/debian.html you had to activate 
the unsecured and experimental repositories at the package manager 
(e.g., apt or synaptic). Otherwise the libraries aren't available. There 
was also an package (libapache2-mod-perl2-doc) my system couldn't 
locate. But I think this package is not so important for OME. :-) So 
forget about it.

Then I started install.pl and I run into problems problems problems. :-)

First of all there where some compiler problems and I played a little 
bit. I cann't remember what I did .. checked some makefiles. - whatever 
- at least the compiler part of install.pl worked .

Then - next problem the apache configuration failled. Ok - I could do it 
manually. The main configuration file at Ubuntu is 
/etc/apache2/apache2.conf ant NOT httpd.conf - Very strange I know. So I 
put an Include pathToOME/conf/httpd.conf.ome at the bottom of 
apache2.conf. Then I changed at all OME/conf/*.conf files the line 
PerlInitHandler Apache::Reload to PerlInitHandler Apache2::Reload and I 
checked the rest of the pathes like PerlSetEnv Path and Alias - Now 
Apache configuration was fine.

Next problem postgresql.  At Ubuntu the apache user is www-data and "-" 
dosn't like postgresql (I read some discussions about this topic in the 
mail archive. Maybe it's fixed in the development version.) But to fix 
it is not so difficult. I changed the line
my $sql = "CREATE USER $username"; at file 
installationPATH/src/perl2/OME/Database/PostgresDelegate.pm to
my $sql = "CREATE USER \"$username\"";    --- and the install.pl 
finished the installation perfectly.

But this doesn't mean that I could login now. There was still a 
configuration problem with postgresSQL. Install.pl runs under root - the 
apache server not. So I had to change the "Connections and 
authentification" settings of postgressql.conf.
After this finally I could login using the webinterface. But I'm still 
not very happy. Image import dosn't work. An import process is started, 
I get a PID. But then this process freezes. I waited more than 2 hours 
of an import of one TIFF (same with jpeg and lsm)
At the end I had to kill the processes.
The Java Client also doesn't work. Error at apache.log "...can't locate 
Apache2.pm in @INC(..."
What is @INC? Apache2.pm is available put not in the path searched by 
@INC parameter.

That's all! Have a nice day wherever you are. Today I'll go to the 
Oktoberfest in Munich - so the world is not so bad :-))
