How to Install MySQL 8.0/5.7 on CentOS 7 / RHEL 7


MySQL is a free and open-source database management system, commonly used in web applications to store and retrieve records and information.

MySQL was initially developed by MYSQL AB, now owned by Oracle Corporation. It was the primary database application for Linux operating system until MariaDB, a fork of MySQL, came into the picture.

In this article, we will see how to install MySQL 8.0/5.7 on CentOS 7 / RHEL 7.

Add MySQL Repository

MySQL is no longer distributed through OS repositories. So, you would need to add an official repository of MySQL to install the MySQL community server.

rpm -ivh

Make sure the MySQL repository has been added and enabled by using the following command.

yum repolist all | grep mysql | grep enabled

Output: May Look like.

mysql-connectors-community/x86_64   MySQL Connectors Community   enabled:    221
mysql-tools-community/x86_64        MySQL Tools Community        enabled:    135
mysql80-community/x86_64            MySQL 8.0 Community Server   enabled:    301

Install MySQL Community Server

Oracle currently offers both stable versions (v8.0 and v5.7). You can choose the one you want to install on your machine.

Install MySQL 8.0

Use the yum command to install MySQL community server 8.0.

yum install -y mysql-community-server

Install MySQL 5.7

If you want to try the older version of MySQL, then install MySQL 5.7 on your machine with the below command.

yum install -y mysql-community-server --disablerepo=mysql80-community --enablerepo=mysql57-community

After the installation of MySQL, you can start the MySQL server using the following command.

systemctl start mysqld

Then, enable MySQL service to start automatically at system startup.

systemctl enable mysqld

Finally, verify if the MySQL server is started using the following command.

systemctl status mysqld

Initial MySQL Root Password

In CentOS/RHEL, you can find the initial MySQL root password in /var/log/mysqld.log. You can use the below command to take the password from the log file.

cat /var/log/mysqld.log | grep -i 'temporary password'


2021-11-27T08:27:27.063799Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: PJyCjhTjP1:n

Secure MySQL server

Now, you need to run mysql_secure_installation to secure your MySQL installation. This command takes care of setting the root password, removing anonymous users, disallowing root login remotely, etc.



Securing the MySQL server deployment.

Enter password for user root:  << Enter the initital MySQL root password

The existing password for the user account root has expired. Please set a new password.

New password:  << Enter new MySQL root password

Re-enter new password:  << Re-enter new MySQL root password
The 'validate_password' component is installed on the server.
The subsequent steps will run with the existing configuration
of the component.
Using existing password for root.

Estimated strength of the password: 100
Change the password for root ? ((Press y|Y for Yes, any other key for No) : N  << Type N as we have already set new password

 ... 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

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y  << Type Y to remove anonymous users

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  << Type Y to disallow root login remotely

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

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y  << Type Y to remove test database
 - Dropping test database...

 - Removing privileges on test database...

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  << Type Y to reload privilege tables

All done!

Work with MySQL Server

Login to MySQL server with the root user and its password.

mysql -u root -p
