You can recover MySQL database server password with following five easy steps.

Step # 1: Stop the MySQL server process.

Step # 5: Exit and restart the MySQL server.
Here are commands you need to type for each step (login as the root user):

Step # 1 : Stop mysql service
# /etc/init.d/mysql stop


Step # 2: Start to MySQL server w/o password:
# mysqld_safe --skip-grant-tables &
Step # 3: Connect to mysql server using mysql client:
# mysql -u root
Step # 4: Setup new MySQL root user password
mysql> use mysql;
mysql> update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
mysql> flush privileges;
mysql> quit

Step # 5: Stop MySQL Server:
