This article will walk through you the process of installing and updating latest MySQL 5.7.9 version onRHEL/CentOS 7/6/5 and Fedora 23/22/21 using MySQL Yum repository via YUM utility.

Step 1: Adding the MySQL Yum Repository

1. We will use official MySQL Yum software repository, which will provides RPM packages for installing the latest version of MySQL server, client, MySQL Utilities, MySQL Workbench, Connector/ODBC, and Connector/Python for the RHEL/CentOS 7/6/5 and Fedora 23-21.

Important: These instructions only works on fresh installation of MySQL on the server, if there is already a MySQL installed using a third-party-distributed RPM package, then I recommend you to upgrade or replace the installed MySQL package using the MySQL Yum Repository”.

Before Upgrading or Replacing old MySQL package, don’t forget to take all important databases backup and configuration files.

2. Now download and add the following MySQL Yum repository to your respective Linux distribution system’s repository list to install the latest version of MySQL (i.e. 5.7.9 released on 21 October 2015).

--------------- On RHEL/CentOS 7 ---------------

# wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm

--------------- On RHEL/CentOS 6 ---------------

# wget http://dev.mysql.com/get/mysql57-community-release-el6-7.noarch.rpm

--------------- On RHEL/CentOS 5 ---------------

# wget http://dev.mysql.com/get/mysql57-community-release-el5-7.noarch.rpm

--------------- On Fedora 23 ---------------

# wget http://dev.mysql.com/get/mysql57-community-release-fc23-7.noarch.rpm

--------------- On Fedora 22 ---------------

# wget http://dev.mysql.com/get/mysql57-community-release-fc22-7.noarch.rpm

--------------- On Fedora 21 ---------------

# wget http://dev.mysql.com/get/mysql57-community-release-fc21-7.noarch.rpm

3. After downloading the package for your Linux platform, now install the downloaded package with the following command.

--------------- On RHEL/CentOS 7 ---------------

# yum localinstall mysql57-community-release-el7-7.noarch.rpm

--------------- On RHEL/CentOS 6 ---------------

# yum localinstall mysql57-community-release-el6-7.noarch.rpm

--------------- On RHEL/CentOS 5 ---------------

# yum localinstall mysql57-community-release-el5-7.noarch.rpm

--------------- On Fedora 23 ---------------

# dnf localinstall mysql57-community-release-fc23-7.noarch.rpm

--------------- On Fedora 22 ---------------

# dnf localinstall mysql57-community-release-fc22-7.noarch.rpm

--------------- On Fedora 21 ---------------

# yum localinstall mysql57-community-release-fc21-7.noarch.rpm

The above installation command adds the MySQL Yum repository to system’s repository list and downloads the GnuPG key to verify the integrity of the packages.

4. You can verify that the MySQL Yum repository has been added successfully by using following command.

# yum repolist enabled | grep "mysql.*-community.*"

# dnf repolist enabled | grep "mysql.*-community.*"      [On Fedora 22+ versions]

Verify MySQL Yum Repository

Step 2: Installing Latest MySQL Version

5. Install latest version of MySQL (currently 5.7) using the following command.

# yum install mysql-community-server

# dnf install mysql-community-server      [On Fedora 22+ versions]

The above command installs all the needed packages for MySQL server mysql-community-server, mysql-community-client, mysql-community-common and mysql-community-libs.

Step 3: Installing MySQL Release Series

6. You can also install different MySQL version using different sub-repositories of MySQL Community Server. The sub-repository for the recent MySQL series (currently MySQL 5.7) is activated by default, and the sub-repositories for all other versions (for example, the MySQL 5.6 or 5.5 series) are deactivated by default.

To install specific version from specific sub-repository, you can use --enable or --disable options usingyum-config-manager or dnf config-manager as shown:

# yum-config-manager --disable mysql57-community

# yum-config-manager --enable mysql56-community

------------------ Fedora 22+ Versions ------------------

# dnf config-manager --disable mysql57-community

# dnf config-manager --enable mysql56-community

Step 4: Starting the MySQL Server

7. After successful installation of MySQL, it’s time to start the MySQL server with the following command:

# service mysqld start

You can verify the status of the MySQL server with the help of following command.

# service mysqld status

This is the sample output of running MySQL under my CentOS 7 box.

Redirecting to /bin/systemctl status  mysqld.service

mysqld.service - MySQL Server

   Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled)

   Active: active (running) since Thu 2015-10-29 05:15:19 EDT; 4min 5s ago

  Process: 5314 ExecStart=/usr/sbin/mysqld --daemonize $MYSQLD_OPTS (code=exited, status=0/SUCCESS)

  Process: 5298 ExecStartPre=/usr/bin/mysqld_pre_systemd (code=exited, status=0/SUCCESS)

 Main PID: 5317 (mysqld)

   CGroup: /system.slice/mysqld.service

           └─5317 /usr/sbin/mysqld --daemonize

Oct 29 05:15:19 localhost.localdomain systemd[1]: Started MySQL Server.

Check Mysql Status

8. Now finally verify the installed MySQL version using following command.

# mysql --version

mysql  Ver 14.14 Distrib 5.7.9, for Linux (x86_64) using  EditLine wrapper

Check MySQL Installed Version

Step 5: Securing the MySQL Installation

9. The command mysql_secure_installation allows you to secure your MySQL installation by performing important settings like setting the root password, removing anonymous users, removing root login, and so on.

# mysql_secure_installation

Now follow the onscreen instructions carefully, for reference see the output of the above command below.

Sample Output
Securing the MySQL server deployment.

Enter password for user root: Enter New Root Password

VALIDATE PASSWORD PLUGIN can be used to test passwords

and improve security. It checks the strength of password

and allows the users to set only those passwords which are

secure enough. Would you like to setup VALIDATE PASSWORD plugin?

Press y|Y for Yes, any other key for No: y

There are three levels of password validation policy:

LOW    Length >= 8

MEDIUM Length >= 8, numeric, mixed case, and special characters

STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2

Using existing password for root.

Estimated strength of the password: 50

Change the password for root ? ((Press y|Y for Yes, any other key for No) : y

New password: Set New MySQL Password

Re-enter new password: Re-enter New MySQL Password

Estimated strength of the password: 100

Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y

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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : y

Success.

All done!

Step 6: Connecting to MySQL Server

10. Connecting to newly installed MySQL server by providing username and password.

# mysql -u root -p

Sample Output:

Welcome to the MySQL monitor.  Commands end with ; or \g.

Your MySQL connection id is 19

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Connect to MySQL Server

Step 7: Updating MySQL with Yum

11. Besides fresh installation, you can also do updates for MySQL products and components with the help of following command.

# yum update mysql-server

# dnf update mysql-server       [On Fedora 22+ versions]

Update MySQL Version

When new updates are available for MySQL, it will auto install them, if not you will get a message saying NO packages marked for updates.

That’s it, you’ve successfully installed MySQL 5.7.9 on your system. If you’re having any trouble installing feel free to use our comment section for solutions.
