Webmux.pl make Apache2 crash

Hello World.

I am getting crazy with this problem…

I had installed in a Fedora Core 3, Apache2 + MySQL + mod_perl-1.99_16-3

The installation notes:
./configure --prefix=/usr/local/rt3
–with-db-type=mysql --with-web-group=nobody --with-web-user=nobody
–with-db-rt-pass=xxx

perl sbin/rt-test-dependencies --with-mysql --with-modperl2 --install
perl sbin/rt-test-dependencies --with-mysql --with-modperl --install

NOTE: I had desesperatily tried both lines with the same result.

make install
make initialize-database

Everything at this point seems good, the install said that everything goes
fine, and before of adding the rt3 config file to the apache, it works
fine (apache + modperl) but after adding this file to apache conf.d
directory it is not working:

/etc/httpd/conf.d/rt3.conf

ServerName xxx.xxxx.es DocumentRoot /usr/local/rt3/share/html AddDefaultCharset UTF-8

these four lines apply to Apache2+mod_perl2 only: {{{ <<< I had

tried commenting this lines too.
PerlSetVar MasonArgsMethod CGI
PerlModule Apache2 Apache::compat
RewriteEngine On
RewriteRule ^(.*)/$ $1/index.html

}}}

PerlModule Apache::DBI
PerlRequire /usr/local/rt3/bin/webmux.pl

<Location />
    SetHandler perl-script
    PerlHandler RT::Mason
</Location>

The Httpd start resutls:

I had checked that there is not dependencies installing all required
modules via CPAN.

Sorry for my English but I had read nearly 100 post looking for that
problem, with no success…

Thanks in advance.

What are the permissions on /usr/lib/perl5/5.8.5/i386-linux-thread-multi/auto/MIME/Base64/Base64.so ?
Is it simply that the web server user cannot read the .so file?

Hello.

Finally I had found following the goggling send by Ruslan the solution, it
was described at:

I don’t know how to solve perfectly.
But this is just a SELinux problem.
You can see some message in /var/log/messages after /sbin/service httpd restart
After all, easy wat to run httpd is edit /etc/SELinux/config and change
enforcing to permissive.
I think it’s a transitional consistency problem.
May be someone correct at some time.

[for reference] /etc/selinux/targeted/contexts/files/file_contexts describe
files that can be accesible by httpd

Sanya Moriyama
I forget writing enough.
after changing /etc/selinux/config , we need to reboot a machine.

more details will be below.

Hello.

Already I had installed RT in a Fedora Core 3 Apache 2 + Mod_perl 1.99 +
MySQL.

Apache starts and I can load the RT login page in my browser, but what is
the user/pass that I had to put in the box??

I had read in
Hardware | Oracle that this
user must be the user setup at configuration time but it seems not to work.
I put in the login box : User: rt or rt_user or root and his corresponding
passwrods but nothing happens.

Compilation notes:
./configure --prefix=/usr/local/rt3
–with-db-type=mysql --with-rt-group=rt --with-db-dba=root
–with-db-rt-user=rt_user --with-web-group=nobody --with-web-user=nobody
–with-db-rt-pass=xxxxx

perl sbin/rt-test-dependencies --with-mysql --with-modperl2
make install
make initialize-database

Significant parts of my RT_Siteconfig.pm

#The name of the database user (inside the database)
Set($DatabaseUser , ‘rt_user’);

Password the DatabaseUser should use to access the database

Set($DatabasePassword , ‘xxxx’);

The name of the RT’s database on your database server

Set($DatabaseName , ‘rt3’);

My apache’s error_log said:

[Thu Dec 2 13:10:08 2004] [error]: FAILED LOGIN for root from

[Thu Dec 2 13:10:19 2004] [error]: FAILED LOGIN for rt from 62.204.xxx.xx

grep password rt-3.2.2/README

NOTE: root’s password for the web interface is “password”
