MySQL 5.4 beta already hit freebsd ports and I eager to try it after read a lot of review.
Everyhing seem OK until I want to start the server.

# /usr/local/etc/rc.d/mysql-server restart
mysql not running? (check /var/db/mysql/proxy2.host.com.pid)

hmmm, perhaps I can try mysqld_safe

# /usr/local/bin/mysqld_safe &
[1] 87164
proxy2# WARNING: Found /var/db/mysql/my.cnf
Datadir is deprecated place for my.cnf, please move it to /usr/local/etc

Starting mysqld daemon with databases from /var/db/mysql
STOPPING server from pid file /var/db/mysql/proxy2.host.com.pid
090725 10:46:54 mysqld ended

What, after a moment I try to follow it.

# mv /var/db/mysql/my.cnf /usr/local/etc/

restart again and still not work, after remove it completely I see it work.

# rm /usr/local/etc/my.cnf

Hmm, I think I have to downgrade back to 5.0.84 and wait till 5.4 final 🙂
