I have solved my previous problem but now have another one. I get an Error 500 - Internal Server Error.

Apache_1.3.26 - With DSO Support, mod_perl.so

Please let me know if I need to provide any more info.

And while you’re at it, rebuild mod_perl to be statically linked to apache.

From the RT README:

I wish people would stop promoting this myth.

Please explain. Is this no longer true? Are people successfully using
mod_perl v1.99 as a DSO with Apache 1.3.23 and RT?

I’ll confirm that I’ve seen in recent tarballs of mod_perl the fixing of
breakage under mod_perl – somewhere in the toplevel documentation, most
likely in README.apaci.

the pre-release mod_perl 1.99 does not work with apache 1.x; it is
only for apache2, and has not been officially released.

current released mod_perl under apache 1.2 works just fine with DSO.
the only hitch may be a big memory leak on server restart (so just
stop/start it instead). if not, then report it as a bug to the
mod_perl developers.

Sorry, my mistake. I have mod_perl 1.99 here for testing something
else, but you’re right, I’m really using mod_per 1.26 with apache
1.3.23. I’ll try it as a DSO some time. I suppose someone ought to
update the RT FAQ and docs; shared libs are a big win normally.

Myth?

I’ve seen mod_perl as a DSO misbehave in very subtle ways on Tru64
Unix–problems which went away completely when mod_perl was linked
into apache. From experience, I believe it is true that mod_perl as a
DSO may have serious stability problems, depending a great deal on
the platform (and possibility the perl build options as well).

Just because you haven’t seen it doesn’t make it a myth…

Well it’s definitely an inability to connect to your mysql server.

  1. First thing to check is if the user/password actually works:

    mysql -u -p

if you can’t get in, you need to add the user to the DB.

  1. Check if and where the socket is actually activated in your mysql
    config.

Those generally will help figure out the problem, but they are just from
the top of my head.

DBI connect(‘dbname=rt3;host=localhost’,‘rt_user’,…)
failed: Can’t connect to local MySQL server through
socket ‘/tmp/mysql.sock’ (2) at

well, is /tmp/mysql.sock where your mysql leaves it’s socket? I bet
not.

mysql tries to use the socket to talk to the server when the hostname
is localhost. However, DBD::mysql doesn’t read my.cnf, which means
that if your socket is in a funny location, you can lose trying to
connect to database running on localhost.

There are 2 easy ways to fix this. Not using “localhost” as the db
server name should work, or you can set the environmental variable
MYSQL_UNIX_PORT appropriately. for example, one of my RT_SiteConfig
files has: $ENV{‘MYSQL_UNIX_PORT’}=“/opt/mysql/var/mysql.sock”;

May be your mysql is stopped? Did you run make initdb while RT install?

As variant you can add
[mysqld]
…
socket=/tmp/mysql.sock

to /etc/my.cnf

FreeBSD 5.3 uses more of the rc.conf control, the startup script
for the mysqld is in /usr/local/etc/rc.d. Add the line

mysql_enable=“YES”

to /etc/rc.conf and then as root type

‘/usr/local/etc/rc.d/mysql-server.sh’ start

all this is only helpful, if your server isn’t running, so do a

‘ps -auxww | grep mysqld’

…see if it is running.
