Locate your configuration file. It's usually called my.cnf and in /etc/mysql.
Locate a log-bin entry in my.cnf or add it, if it's not there. log-bin = <location of logfile> Restart the mysql server process.

# Disabling symbolic-links is recommended to prevent assorted security risks;
# to do so, uncomment this line:
