Scary Moment

When I was restarting Apache after installed a new PHP module, I found that httpd.conf was missing, that was scary! I have absolutely no idea how this happened, the only possible reason is that I deleted it by accident. Read More

Another FreeBSD Blog

March 13, 2009 Posted in FreeBSD General

Here is another FreeBSD blog: Real FreeBSD Tips, it looks quite professional. Still too few FreeBSd blogs out there, FreeBSD deserves much more attention. I have no idea how many servers are running FreeBSD, but it should be a very small number compared to Linux.

Finally, AOL unblocked my new IP, their Feedback Loop Request Form doesn’t seem to work, I joined two times and was approved too, but nothing happened. The unblock was done after I got a personal reply to my direct email request.

Monitor MySQL Log File

March 2, 2009 Posted in MySQL

I rarely check MySQL log file, but recently I got some table corruption errors, and it’s hard to notice these errors, especially when these tables are not critical. I realized that it’s necessary to monitor MySQL log file. According to MySQL manual, before version 5.1.20, it’s not possible to log MySQL errors to syslog. I’m still using 5.0, so I added the following line to cron job of my root account:

30 2 * * * tail -n 50 /var/db/mysql/hostname.err

Now I get notification email daily (no email if it’s empty), not a bad solution.
