Set up mysql server

Installing:

yum install mysql mysql-server php-mysql

Chkconfig

chkconfig --level 345 mysqld on

Manual start

/etc/init.d/mysqld start
 ...
 PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
 To do so, start the server, then issue the following commands:
  /usr/bin/mysqladmin -u root password 'new-password'
 /usr/bin/mysqladmin -u root -h tortoise password 'new-password'

 Alternatively you can run:
  /usr/bin/mysql_secure_installation
 ...

Run /usr/bin/mysql_secure_installation and accept all defaults.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!


By default, a MySQL installation has an anonymous user, allowing anyone
to log into MySQL without having to have a user account created for
them.  This is intended only for testing, and to make the installation
go a bit smoother.  You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n]
... Success!

Normally, root should only be allowed to connect from 'localhost'.  This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n]
... Success!

By default, MySQL comes with a database named 'test' that anyone can
access.  This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n]
- Dropping test database...
ERROR 1010 (HY000) at line 1: Error dropping database (can't rmdir './test', errno: 13)
... Failed!  Not critical, keep moving...
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n]
... Success!

Cleaning up...



All done!  If you've completed all of the above steps, your MySQL
installation should now be secure.

Thanks for using MySQL!
