Setting the root password on MySQL

I just installed MySQL version 4.1.20 on my CentOS 4.4 server. The default install of MySQL server uses a blank password for root so I had to have it changed. I also set the MySQL service to start up every time my machine boots up.

This is how I did it;

Method 1

1. # yum -y install mysql-server (This will install the mysql binaries)
2. # chkconfig mysqld on (Adds mysqld to the startup services)
3. # service mysqld start (Starts the MySQL server)
4. # mysql -u root@localhost (Brings up the MySQL console)
5. #mysql> set password for root=password(‘password’); (Sets the root password to “password”)
6. #mysql> reload privileges; (Reloads the grant tables)

Method 2

1. # mysql -u root (Brings up the MySQL console)
2. #mysql> use mysql (Use the mysql database)
3. #mysql> update user
-> set password=password(“password”) (Sets the root password to “password”)
-> where user=”root”;
4. # reload privileges; (Reloads the grant tables)
That’s it, the next time you want to get the MySQL console up you’ll have to run #mysql -u root -p to get the password prompt.

Post-Installation Setup and Testing at MySQL


This will work too.

/usr/bin/mysqladmin -u root password ‘new-password’
/usr/bin/mysqladmin -u root -h pandora.crib password ‘new-password’
