Why is my server shutting down?

[Jason Cheung]

I start the MySQL server with the "ruby script/server" command.
It loads fine.
When I go to localhost:3000, the server immediately shuts down and
throws out an error. It says:
C:\ruby\lib\ruby\gems\1.8\gems\activerecord-2.3.2\lib\active_record\connection_adapters\abstract_adapter.rb:39:
[BUG] Segmentation fault ruby 1.8.6 (2008-08-11) [i386-mswin32].
I've been looking around online and many have the same error occuring.
I'm running mysql 5.0.83, rails 2.3.2, ruby 1.8.6 and rubygems 1.3.4.

Can anybody help!?
Thanks,
Jay

Can you run ruby -v so we can see the patchlevel?

Certain patchlevels of 1.8.6 have serious issues. Newer ones seem to work fine.

-greg

patchlevel is 287

 

[Gregory Brown]

patchlevel is 287

Hmm... probably not Ruby then. p287 works-for-me.
The next place I'd look would be the mysql adapter. Unfortunately,
it'll take someone else who's using MySQL on Windows to help you w.
that.

Actaully, that's how you are starting you Rails server, most likely.
Usually a MySQL server is started with a command like mysqld_safe.

When I go to localhost:3000, the server immediately shuts down and
throws out an error. It says:
C:\ruby\lib\ruby\gems\1.8\gems\activerecord-2.3.2\lib\active_record

There's some nasty bug in whatever code Rails needs to load to display
the homepage of your site. It really shouldn't be segfaulting, but
that's the issue.

The error looks like it is probably related to connecting to your
database, just because of where it comes from in the code. Here are
some reality check type questions:

* Do you have a database installed?
* Is that database running?
* Is your config/database.yml file correctly pointed at that database?

Beyond that, you may find better help on the Rails mailing list:

For some reason, however, it appears that Rails is unable to find a =20
required MySQL dll. The best fix I=92ve been able to find (ok, I admit =20=

this is clunky, but anyhow it works) is to copy libmySQL.dll from your =20=

MySQL binary directory (for example, C:\Program Files\MySQL\MySQL =20
Server 5.0\bin) into the Ruby binary directory (for example, C:\ruby=20
\bin). Restart your application (shut down and restart the server), =20
then try running it again. For me, that fixes the problem.

In the winows\system32 directory you may find a file called regserver32 or =
something like that. Drag the dll onto that and drop and see if that fixes =

It's working now. I wish I could shed a bit of light on how it was fixed
but it literally just started working by itself.
