Back at SLES10

Here I am, sitting at my desk on a Thuesday evening thinking about what happened the last few days.

  1. I finally got to play around with our PacketPro 450 Cluster (nifty LoadBalancing appliance)
  2. We reworked the network the way *we* want it (and not that tool of a wannabe sysadmin)
  3. We mostly figured out how to do the LoadBalancing right, we just need to find some bugs in the LoadBalancer software (like the thing is failing over to its slave from time to time, but keeping the IP address for himself) or let the guys at teamix do their work and hopefully get a working release within the next week or so
  4. I figured out how to setup interface bonding with SLES10 (it was quite straight forward, thanks to the excellent in-kernel documentation), and we’re using an active-backup mode for now
  5. I still need to figure out how to do the MySQL Master<->Master replication right .. I’m currently building fresh RPM’s on one of those Dell blades (yes, they ROCK!) which will hopefully be finished till I’m at the office tomorrow.
  6. Pt. 5 also includes figuring out how to pass MySQL a custom location for the binary-log, at least that’s what the handbook says in Chapter “5.11.3. The Binary Log” …

When started with the –log-bin[=base_name] option, mysqld writes a log file containing all SQL commands that update data. If no base_name value is given, the default name is the name of the host machine followed by -bin. If the basename is given, but not as an absolute pathname, the server writes the file in the data directory. It is recommended that you specify a basename; see Section B.1.8.1, “Open Issues in MySQL”, for the reason.

That behavior works for –log-bin-index (like log-bin-index=/mysql/binlogs/$HOSTNAME.idx), but doesn’t for –log-bin. *shrug* I’ll see if that is fixed with something >5.0.18 (that’s what SLES10 currently ships).

I’m also looking for a network topology drawing program (possibly free), as Microsoft Visio (either 2003 or 2007, Standard or Professional) is nice, but still can’t draw shit correctly. So I stumbled upon yEd, which seems to look nice (I haven’t yet looked at it, but will tomorrow) that hopefully gives me the opportunity to draw/visualize my setup at work 😯
