MySQL is a popular database management system used for web and server applications. This guide will introduce how to install, configure and manage MySQL on a Linode running CentOS 6.

Before You Begin

  1. Ensure that you have followed the Getting Started and Securing Your Server guides, and the Linode’s hostname is set.

    To check your hostname run:

    The first command should show your short hostname, and the second should show your fully qualified domain name (FQDN).

  2. Update your system:

Install and Start MySQL

How To Install Hping3 In Linux

  1. Install MySQL and tell it which runlevels to start on:

  2. Then to start the MySQL server:

    MySQL will bind to localhost (127.0.0.1) by default. Please reference our MySQL remote access guide for information on connecting to your databases using SSH.

Note
Allowing unrestricted access to MySQL on a public IP not advised, but you may change the address it listens on by modifying the bind-address parameter in /etc/my.cnf. If you decide to bind MySQL to your public IP, you should implement firewall rules that only allow connections from specific IP addresses.

Harden MySQL Server

  1. Run the mysql_secure_installation script to address several security concerns in a default MySQL installation.

You will be given the choice to change the MySQL root password, remove anonymous user accounts, disable root logins outside of localhost, and remove test databases. It is recommended that you answer yes to these options. You can read more about the script in MySQL Reference Manual.

If you want to use PHP in conjunction with MySQL, you should install libapache2-mod-php and php-mysql sudo apt update && sudo apt install libapache2-mod-php php-mysql 2. The first command will update the package lists to ensure you get the latest version and dependencies for PHP. The second command will then download and install PHP. Installing apache and php. Sudo apt update && sudo apt install php Press y and ENTER when prompted to install the PHP package. Press y and ENTER when asked to continue.

Using MySQL

The standard tool for interacting with MySQL is the mysql client which installs with the mysql-server package. The MySQL client is used through a terminal.

Root Login

  1. To log in to MySQL as the Root User:

  2. When prompted, enter the root password you assigned when the mysql_secure_installation script was run.

    You’ll then be presented with the MySQL monitor display:

  3. To generate a list of commands for the MySQL prompt, enter h. You’ll then see:

Create a New MySQL User and Database

  1. In the example below, testdb is the name of the database, testuser is the user, and password is the user’s password.

    You can shorten this process by creating the user while assigning database permissions:

  2. Then exit MySQL.

Create a Sample Table

  1. Log back in as testuser.

  2. Create a sample table called customers. This creates a table with a customer ID field of the type INT for integer (auto-incremented for new records, used as the primary key), as well as two fields for storing the customer’s name.

  3. Then exit MySQL.

Reset the MySQL Root Password

If you forget your root MySQL password, it can be flushed and then reset.

  1. Stop the current MySQL server instance, then restart it with an option to not ask for a password.

  2. Reconnect to the MySQL server with the MySQL root account.

  3. Use the following commands to reset root’s password. Replace password with a strong password.

  4. Then restart MySQL.

You’ll now be able to log in again using mysql -u root -p.

Tune MySQL

MySQL Tuner is a Perl script that connects to a running instance of MySQL and provides configuration recommendations based on workload. Ideally, the MySQL instance should have been operating for at least 24 hours before running the tuner. The longer the instance has been running, the better advice MySQL Tuner will give.

  1. Download MySQL Tuner to your home directory.

  2. To run it:

    The output will show two areas of interest: General recommendations and Variables to adjust.

MySQL Tuner is an excellent starting point to optimize a MySQL server but it would be prudent to perform additional research for configurations tailored to the application(s) utilizing MySQL on your Linode.
