When I type: ./mysqld

I get:

# Can't start server: Bind on TCP/IP port: Address already in use
# Do you already have another mysqld server running on port: 3306 ?
# Aborting

Then I typed: ps aux|grep mysqld

I get:

mysql 507 0.0 3.6 10772 1120 ? SN 16:15 0:00 /usr/sbin/mysqld
mysql 509 0.0 3.6 10772 1120 ? SN 16:15 0:00 /usr/sbin/mysqld
mysql 510 0.0 3.6 10772 1120 ? SN 16:15 0:00 /usr/sbin/mysqld
root 1239 0.0 1.4 1160 432 pts/0 S 16:52 0:00 grep mysqld

Any help is appreciated...

The server can't start because it's already running. If you want to restart it, you'll have to kill those processes (any mysqld or safe_mysql processes) first and try again.
