Output:

Loaded plugins: changelog, fastestmirror, presto, refresh-packagekit
...

4. Update or Install MySQL 5.5.32

Fedora 18, 17, 16, 15, 14, 13, 12

yum --enablerepo=remi install mysql mysql-server

CentOS 6.4/6.3/6.2/6.1/6/5.9 and Red Hat (RHEL) 6.4/6.3/6.2/6.1/6/5.9

yum --enablerepo=remi,remi-test install mysql mysql-server

5. Start MySQL server and autostart MySQL on boot

Fedora 18/17/16

systemctl start mysqld.service ## use restart after update

systemctl enable mysqld.service

Fedora 15/14/13/12/11, CentOS 6.4/6.3/6.2/6.1/6/5.9 and Red Hat (RHEL) 6.4/6.3/6.2/6.1/6/5.9

/etc/init.d/mysqld start ## use restart after update
## OR ##
service mysqld start ## use restart after update

chkconfig --levels 235 mysqld on

6. MySQL Secure Installation

  • Set (Change) root
  • Remove anonymous users
  • Disallow root login remotely
  • Remove test database and access to it
  • Reload privilege tables

Start MySQL Secure Installation with following command

/usr/bin/mysql_secure_installation

Output:

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.

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] 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!

Note: If you don’t want some reason, do a “MySQL Secure Installation” then at least it’s very important to change the root user’s password

mysqladmin -u root password [your_password_here]

## Example ##
mysqladmin -u root password myownsecrectpass

7. Connect to MySQL database (localhost) with password

mysql -u root -p

## OR ##
mysql -h localhost -u root -p

8. Create Database, Create MySQL User and Enable Remote Connections to MySQL Database

This example uses following parameters:

  • DB_NAME = webdb
  • USER_NAME = webdb_user
  • REMOTE_IP = 10.0.15.25
  • PASSWORD = password123
  • PERMISSIONS = ALL
## CREATE DATABASE ##
mysql> CREATE DATABASE webdb;

## CREATE USER ##
mysql> CREATE USER 'webdb_user'@'10.0.15.25' IDENTIFIED BY 'password123';

## GRANT PERMISSIONS ##
mysql> GRANT ALL ON webdb.* TO 'webdb_user'@'10.0.15.25';

##  FLUSH PRIVILEGES, Tell the server TO reload the GRANT TABLES  ##
mysql> FLUSH PRIVILEGES;

Enable Remote Connection to MySQL Server –> Open MySQL Port (3306) on Firewall (as root user again)

1. Edit /etc/sysconfig/iptables file:

nano -w /etc/sysconfig/iptables

2. Add following INPUT rule:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT

3. Restart Iptables Firewall:

service iptables restart
## OR ##
/etc/init.d/iptables restart

4. Test remote connection:

mysql -h dbserver_name_or_ip_address -u webdb_user -p webdb
