mysqld won't start because disk space is full:

101221 14:06:50 [ERROR] /usr/libexec/mysqld: Error writing file '/var/run/mysqld/mysqld.pid' (Errcode: 28)
101221 14:06:50 [ERROR] Can't start server: can't create PID file: No space left on device

running df -h:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              16G  3.2G   12G  23% /
/dev/sda5             4.8G  4.6G     0 100% /var
/dev/sda3             430G  855M  407G   1% /home
/dev/sda1              76M   24M   49M  33% /boot
tmpfs                 956M     0  956M   0% /dev/shm

du -sh * in /var:

12K     account
56M     cache
24K     db
32K     empty
8.0K    games
1.5G    lib
8.0K    local
32K     lock
221M    log
16K     lost+found

8.0K    racoon
292K    run
70M     spool
8.0K    tmp
76K     webmin
2.6G    www
20K     yp

in /dev/sda5, there is website files in /var/www.

because this is first time, I have no idea which files to remove other than moving /var/www to other partition

And one more, what is the right way to remove log files, history, etc in /dev/sda5?
