Insert data to local mysql server from python connector on beaglebone with angstrom

I have tested my python connector on PC in this article:

Insert data to a mysql server from python ON PC with windows

But the funny thing is that when I move every thing on a beaglebone with Angstrom, I got conection refused error on localhost:3306, I have checked my my.cnf file under etc/

[client]

#password = password

port         = 3306

socket = /tmp/mysql.sock

[mysqld_safe]

err-log = /var/log/mysql.err

[mysqld]

user = mysql

port = 3306

socket = /tmp/mysql.sock

pid-file = /var/lib/mysql/mysqld.pid

log-error = /var/log/mysqld.err

basedir = /usr

datadir = /var/mysql

skip-locking

loose-skip-innodb

skip-networking

bind-address = localhost

Google it, there are several possibilities:

port or socket not correct, but from above, I believe both are correct.

about the bind-address, there are 2 different talk

using mysqladmin variables | grep port 

I got below:

so the port is for sure at 3306, but when doing telenet localhost:3306

connection refused. This could be an issue.

But after comment out skip-networking in my.cnf and retart ....

connection seems working, no more connection refused.
