Installing MySQL 5.0 First we install MySQL 5.0 like this:

sudo apt-get install mysql-server mysql-client

Create a password for the MySQL user root (replace yourrootsqlpassword with the password you want to use):

sudo mysqladmin -u root password yourrootsqlpassword

Then check with

netstat -tap | grep mysql

on which addresses MySQL is listening. If the output looks like this:

tcp 0 0 localhost.localdo:mysql *:* LISTEN 2713/mysqld

which means MySQL is listening on localhost.localdomain only, then you’re safe with the password you set before. But if the output looks like this:

tcp 0 0 *:mysql *:* LISTEN 2713/mysqld

you should set a MySQL password for your hostname, too, because otherwise anybody can access your database and modify data:

sudo mysqladmin -h serverip -u root password yourrootsqlpassword
