Notes regarding SELinux on this platform:
=========================================

The default policy might cause server startup to fail because it is
not allowed to access critical files. In this case, please update
your installation.

The default policy might also cause inavailability of SSL related
features because the server is not allowed to access /dev/random
and /dev/urandom. If this is a problem, please do the following:

1) install selinux-policy-targeted-sources from your OS vendor
2) add the following two lines to /etc/selinux/targeted/src/policy/domains/program/mysqld.te:
allow mysqld_t random_device_t:chr_file read;
allow mysqld_t urandom_device_t:chr_file read;
3) cd to /etc/selinux/targeted/src/policy and issue the following command:
make load

# To create my.cnf by copying from my-large.cnf
# cp -f /usr/share/mysql/my-large.cnf /etc/my.cnf

# To start MySQL Server
# service mysql start
Starting MySQL... [ OK ]

# To assign password for mysql admin user root
# mysqladmin -u root password
New password:
Confirm new password:

# To secure MySQL Installation
# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MySQL to secure it, we'll need the current
password for the root user. If you've just installed MySQL, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

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.

You already have a root password set, so you can safely answer 'n'.

Change the root password? [Y/n] n
... skipping.

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] Y
... 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] Y
... 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] Y
- Dropping test database...
... Success!
- 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] Y
... 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!
