You know when grown-ups tell you everything's going to be fine, and you think they're probably lying to make you feel better?
Yes.

I Think It May Just Be Time For A Reboot

18:25:45 up 518 days, 12:28

I've had servers run that long before, or nearly so, but that's not bad.  But it is starting to show some odd errors - lost database connections, errors starting threads, that sort of thing - that just haven't happened before.

If it gets any worse I'll reboot the server, but first I'll see about getting everything set up on Akane.

Bleh, Foo

Connection to database lost?

It's not supposed to do that - ever.

Don't know why it's decided to fall apart right now.  Maybe it knows I'm setting up the new server today.

You Know What's Cool?

We're virtualised now.  I'll never have to do another messy server move.  When we get the next server (which could be quite a while, since Akane has a much better upgrade path than our previous servers), all I need to do is set up OpenVZ (or Virtuozzo) on the new system, copy the container across, and then on the day of the move, stop the old container, do an rsync update, and start it up on the new server.

A few things broke because of CPanel overwriting configuration files, or version changes of underlying software, or moving from 32-bit to 64-bit.  Next time, none of that will happen.

Really!

Just An Observation

The CPanel installer is as crazy as a bedbug.

It actually works four times out of five.  But reading the log files it creates will give you the impression that not only has it failed, it's crashed your server and the two adjacent servers and set the rack on fire.

Update: It installs 2.6GB of stuff.  Or in one case, 3.1GB.  I'm reinstalling that one.

My favourite part of the whole install process is this:
!! If you  want to create a support ticket with cPanel regarding this please reference 'BuildAP Report Id': '2035297' !!
Stopping portmap: [FAILED]
inetd: no process killed
Shutting down kernel logger: [PASSED]
sendmail: no process killed
open3: exec of /etc/rc.d/init.d/exim stop failed at ./install line 1049
open3: exec of /etc/rc.d/init.d/exim start failed at ./install line 1049
open3: exec of /etc/rc.d/init.d/proftpd start failed at ./install line 1049
If you are getting an "undefined catalog error", please run:
Found hostname to be azusa.mu.nu, which resolves to 174.37.121.36
initfpsuexec: using apache 2.x support
error reading information on service proftpd: No such file or directory
error reading information on service exim: No such file or directory
error reading information on service cpanel: No such file or directory
error reading information on service bandmin: No such file or directory
Starting sshd: [  OK  ]
Cannot open /etc/chkserv.d at /scripts/restartsrv_exim line 99.
What this means is that the main install has completed succsessfully and it's now configuring Apache and PHP.

But you knew that already, right?  After all, if you wanted to indicate success, a string of neon-green boldface messages that use the word "failed" four times and "error" five times would be your first choice.

Speed For Need

Akane, the new mu.nu/mee.nu hyperserver, is as fast as 100,000 PDP-11/70's.

A Big mu.nu Welcome

To Akari, Azusa, and Kodachi!

Akari is a quad-core system with 6GB of RAM; Azusa and Kodachi are dual-core systems with 4GB of RAM.  All running CentOS 5.3 64-bit and CPanel.  They'll be taking over duties from Midori and Sakura.

Next up are Nabiki and Kasumi.  Nabiki is a quad-core system with 4GB of RAM and a dedicated SSD; it's our new database server.  Kasumi is our replication server, to couple our data extra-double-safe.  It's a one-and-a-half core system with 1GB of RAM.

Yeah.

As that last might have alerted you, these are not real, physical, stuff-you-can-kick servers, they're virtual servers under OpenVZ.  It takes about seven seconds to create a new server, but it took about five hours to get all the configuration settings correct* and install CPanel.**

Took a little reading to get up to speed on all the commands and options, but I'm saving about $2500 a year by not paying for the pretty user interface of Virtuozzo, and for $2500 I'm willing to do a little reading.

* At one point I had Akari, Azusa, and Kodachi running with 30% and 20% of a CPU - rather than 30% and 20% of the total number of CPUs.  That was a leetle slow.

** CPanel's installation takes a while at the best of times.  It takes about five whiles if you've accidentally restricted your server to only use one-fifth of one processor.

Joy In The Early Evening

We blew up a high-end Intel SSD at my day job today.  That isn't supposed to happen.
