[gentoo-server] mysql not restarting

[gentoo-server] mysql not restarting

[Darko Luketic]

Hello,

i upgraded mysql a few months ago.
i remember that this upgrade was that one that added the file server-running to /etc/init.d/mysql
i've been running mysql 4 since 08/2005, 1st install.
current installed version is 4.1.21. in this version the check for the server-running file was removed.
the problem appeared 2 upgrades ago. (4.0.x) last version was 4.0.27 , previous 4.0.26 .
when i upgraded to 4.1.21 from 4.0.27 i created a db dump, but not from 4.0.26->4.0.27.
i'm using a nptl-enabled compilation.

problem is i can't start the mysql server through the init script.
i set debug to max possible, but the output is just a counter to 40 and starting mysql failed.
when i'm starting the mysql server by hand with the parameters in the init script,
it runs fine, however as soon as i want to restart daemons depending upon mysql, the mysql server stops,
and i have to start it manually, which is annoying as e.g. i would like to restart apache or other daemons daily through cron.

i know a reboot would very likely solve the problem, but thats not an option. (366 days uptime ruined, nooo :) ).
it's not because of ibdata or similar files, it has to be something in the init script or in the content of some file that
drives the start-stop-daemon crazy.

any help appreciated

i hope my english wasn't too bad.

p.s.: does anyone know of a namebased virtualhosting module or similar for apache2 that doesn't require a graceful apache2 restart?

You could redirect all requests of a certain domain by using
<VirtualHost IP:80>
  ServerName *.domain.tld

 (other options needed for your vhost)
</VirtualHost>

Then you could easily determine which of your "virtual" vhosts is
requested by using PHP. The current domainname is stored in the special
variable $_SERVER['HTTP_HOST'] (something like "subdomain.domain.tld").

Now you can decide what page to display. But please note that this
solution requires a PHP call for every file you serve (including CSS and
images). This may cause a significant performance impact because Apache
won't able to cache anything.

If you do not need to configure things per vhost you could just use 
mod_rewrite to create some rules of how to create a path from the host 
asked for.

Hello Darko,

Are you saying that turning up the debug puts nothing in the logs? I
don't use mysql, but something ought to be logged. If not, what I
often do is start the daemon manually, and if that isn't enough,
strace it.

As to the vhosts thing, please read the documentation here:
http://httpd.apache.org/docs/2.0/vhosts/mass.html

Good luck,
Peter

yes, i learned about that like 2 months ago and i'm using it for another project.
but the current project is creating subdirs and linking the source dirs and files (by ln -s)
to that created dirs, the conf file in apache2's vhosts.d dir is created and a reloadme file, which
is checked by a compiled c binary for existence through cron, and does a graceful apache2 restart.
hmm, i've got an idea, thanks for reminding me :)

but apart from that , i've really searched alot and not found anything similar to
http://www.crazygreek.co.uk/content/mod_shapvh
for apache2 which could be used for different things , as described on the website in the above link.

I've used variations on this a long time ago. It worked fairly well.

http://httpd.apache.org/docs/1.3/mod/mod_vhost_alias.html

For simple name-based virtual hosts you might use the following 
directives in your server configuration file:

     UseCanonicalName    Off
     VirtualDocumentRoot /usr/local/apache/vhosts/%0

or if you'd like it all in Mysql

*  net-www/mod_vdbh
       Latest version available: 1.0.3-r1
       Latest version installed: [ Not Installed ]
       Size of files: 7 kB
