RE: [cobalt-users] MYSQL server gone down overnight - newbie requires help

Hi,

I had the same problem some months ago. It has something to do with the
web.cache files that are to BIG. They are generated  every night with
cron.daily.

Will de Haan from Cobalt gave me the following UN-suported solution.


The cache file is generated by analog when invoked from
/usr/local/sbin/split_logs which is invoked from
/etc/logrotate.d/apache.

You do want split_logs to sort through /var/log/httpd/access and create
all the per-site logs as it does now, but you don't want it to invoke
analog.

There are a few ways of resolving this problem.

*** The following suggestions are unsupported and are issued as free,
friendly, useful help ***

You could disable analog, the application and create a dummy in its
place:

  mv /usr/local/sbin/analog /usr/local/sbin/analog.disabled
  echo "#!/bin/sh" > /usr/local/sbin/analog
  echo "exit 0" >> /usr/local/sbin/analog
  chmod +x /usr/local/sbin/analog

Now be aware that ALL built-in site and server Cobalt statistics will no
longer generate.  The changes listed above appear to work on one of my
development RaQs.

To undo this change, should it cause a problem a few months down the
road:

  mv /usr/local/sbin/analog.disabled /usr/local/sbin/analog

...Remember that any OS Update package files that update analog will
overwrite /usr/local/sbin/analog so you'd have to reapply this hack.

Onderwerp: [cobalt-users] MYSQL server gone down overnight - newbie
requires help


Hi all,

We have a cobalt raq4 that we are having problems with!!!!!!

I arrived at work this morning to find some of our web pages not working,
after checking that there was not a problem with the php scripts I soon
determined that there was a problem with the mysql database.

This is compounded by the fact that PHPMyAdmin will not connect and throws
out this error message:

Warning: MySQL Connection Failed: Can't connect to local MySQL server
through socket '/tmp/mysql.sock' (111) in
/home/sites/site2/users/ring1/web/phpMyAdmin/lib.inc.php on line 170
Error

We have been receiving error messages for the last few days stating that the
cobalt box is low on memory at about 5.30 in the morning when some backup
scripts are run, I have checked the messages this morning and they appear to
be somewhat worse.
Snippets as follows:

The SMTP (mail) server appears to be down.  The mail server may shut itself
down temporarily under extreme load, so you should also check the CPU load
on the server. - MAIL IS OK NOW!

subject of other messages:
RE: THE COBALT SERVER IS LOW ON MEMORY
RE: THE COBALT SERVER IS VERY LOW ON MEMORY
RE: THE CPU IS HEAVILY LOADED

Apologies for the long message, but I am fairly new to all of this and my
boss is not in this morning so i am slightly panicking!

Any help would be appreciated

Marcus Miller

Contact me off list and I would be happy to share some calendaring software
I have been working on. Its just some basic perl code.
It produces a simple calendar with daily hyper links for each day. Its very

Hello all,

My question is about getting the secondary name server updated to match the
primary NS.  My primary NS is a RAQ-3i.  My secondary NS is a RAQ-4r.
I setup the 2 A records and the MX record for a domain (on the primary NS)
and it works, but I thought the secondary NS would update itself from the
primary NS.  This does not happen.  Is there a setting that I am missing or
do I need to setup the domain on both NS's

On the slave (secondary)
Secondary Name Service for Domain
enter the name of the domain and it's ip addres
save and all that stuff.

On the master (primary) edit the SOA record for the domain (top edit icon)
add the Secondary Name Server (NS) Host Name (optional)

The primary /etc/named directory should get some files sec.domain.tld

Subject: [cobalt-users] PMFirewall and IPChains: Traceroute Stops Working
Reply-To: cobalt-users@xxxxxxxxxxxxxxx

Hi all. Thanks to Gerald I got my firewall rules working great on all
subnets except for one problem. Before starting the firewall traceroute runs
fine and resolves the host. When I start the firewall, everything functions
properly (http, ftp, email, etc) except when I run a traceroute it can no
longer find the route to the ip. Trace route stops right before or at my
router. When I went through the install script for pmfirewall I made sure
DNS was open to all on port 53. Is this the issue? Not sure what setting
would cause this problem. Any ideas where to look? Should I post my rules? I
have PortSentry running already and am so close to finishing my ruleset with
IPChains. Any help would be greatly appreciated! Thanks in advance.

Best regards,

MySQL doesn't come on the Raqs so it was installed by whoever owned it. If
you don't know any of the passwords, there is a way to reset them. Found it
in the archives.

You say that you had PHP 4.1.1 installed for you. Did they configure it with
MySQL? You probably need to take a look at the configurations they did and
see if it has MySQL support compiled in. Make a file called phpinfo.php and
put this in it:

<?php
   phpinfo();
?>

Pull the phpinfo.php file up in a browser and look at the output to see if
it has MySQL support.

HTH,

I used to do a tar/gzip backup solution before moving to the raqbackup.sh
script.  I never had to restore from tar files, but I knew it would be a
little tricky.  Especially getting the ownerships, permissions and making
sure that the site##'s are correct.

I really like the fact that it is using the CMU.  It makes life very easy.
You just use it to do your restore and it takes care of all the rest.  The
latest CMU 2.27 seems to be much more solid than previous versions.  The
only issues I found were with user aliases...but getting the sites and users
up was most important to me.  Cleaning up some aliases seemed like a small
price to pay.

Not an expert here, but both my current 4i and old 3 had similar messages at
boot. I don't think it's a problem you need to worry about and likely is
common on the 3's and 4's for some unknown reason.

I'm a newbie (not at unix admin but at cobalt, I wil get my first RaQ in an
hour). I thought there was supposed to be a cron-like backup util in the
administratorinterface. Is this something different? And why not use that
one?
