After installing MySQL, it's important that you secure the installation by
a) removing anonymous accounts and
b) setting a password on the admin account.
This can be done with mysqladmin or with direct SQL queries. I prefer the SQL queries so that's what I'll show here.
- Start mysql command line utility and select the mysql database.
- Remove anonymous accounts.
- Set a password on the mysql root account.
- Flush privileges.
[root@localhost]# mysql Welcome to the MySQL monitor. Commands end with ; or \g.
