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 work on the task of how to Install MySQL 8.0 on CentOS 7/6, RHEL 7/6 & Fedora 28/27/26.
Add MySQL Repository
MySQL is no longer distributed through base operating system image or available in OS repositories. So, you would need to add an official repository of MySQL to install MySQL community server.
### CentOS 7 / RHEL 7 ### rpm -ivh https://dev.mysql.com/get/mysql80-community-release-el7-1.noarch.rpm ### CentOS 6 / RHEL 6 ### rpm -ivh https://dev.mysql.com/get/mysql80-community-release-el6-1.noarch.rpm ### Fedora 28 ### rpm -ivh https://dev.mysql.com/get/mysql80-community-release-fc28-1.noarch.rpm ### Fedora 27 ### rpm -ivh https://dev.mysql.com/get/mysql80-community-release-fc27-1.noarch.rpm ### Fedora 26 ### rpm -ivh https://dev.mysql.com/get/mysql80-community-release-fc26-1.noarch.rpm
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: 51 mysql-tools-community/x86_64 MySQL Tools Community enabled: 63 mysql80-community/x86_64 MySQL 8.0 Community Server enabled: 17
Install MySQL Community Server
Oracle currently offers both stable versions (v8.0 and v5.7). You can choose the one you want to install it on your machine.
Install MySQL 8.0
Use yum command in CentOS/RHEL and dnf command in Fedora to install the latest stable version of MySQL.
### CentOS 7/6 & RHEL 7/6 ### yum -y install mysql-community-server ### Fedora 28/27/26 ### dnf -y install 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.
### CentOS 7/6 & RHEL 7/6 ### yum -y install mysql-community-server --disablerepo=mysql80-community --enablerepo=mysql57-community ### Fedora 28/27/26 ### dnf -y install mysql-community-server --disablerepo=mysql80-community --enablerepo=mysql57-community
Start MySQL server
After the installation of MySQL, you can start MySQL server using the following command.
### CentOS 7 / RHEL 7 / Fedora 28/27/26 ### systemctl start mysqld ### CentOS 6 / RHEL 6 ### service mysqld start
Enable MySQL server at system startup.
### CentOS 7 / RHEL 7 / Fedora 28/27/26 ### systemctl enable mysqld ### CentOS 6 / RHEL 6 ### chkconfig mysqld on
Verify that MySQL server is started using the following command.
### CentOS 7 / RHEL 7 / Fedora 28/27/26 ### systemctl status mysqld ### CentOS 6 / RHEL 6 ### service mysqld status
Output:
CentOS 7 / RHEL 7 / Fedora:
● mysqld.service - MySQL Server Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2018-06-15 00:09:36 EDT; 21s ago Docs: man:mysqld(8) http://dev.mysql.com/doc/refman/en/using-systemd.html Main PID: 8452 (mysqld) Status: "SERVER_OPERATING" CGroup: /system.slice/mysqld.service └─8452 /usr/sbin/mysqld Jun 15 00:09:23 server.holhol24.local systemd[1]: Starting MySQL Server... Jun 15 00:09:36 server.holhol24.local systemd[1]: Started MySQL Server.
CentOS 6 / RHEL 6 :
mysqld (pid 2258) is running...
Secure MySQL server
In CentOS/RHEL/Fedora, initial MySQL root password can be found in /var/log/mysqld.log. You can use below command to take the password from the log file.
cat /var/log/mysqld.log | grep -i 'temporary password'
Output:
2017-11-25T07:02:29.549979Z 1 [Note] A temporary password is generated for root@localhost: Ed*Sn(6R9q0h
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, disallow root login remotely, etc.
mysql_secure_installation
Output:
Securing the MySQL server deployment. Enter password for user root: <== Enter Root password taken from previous step The existing password for the user account root has expired. Please set a new password. New password: <== Enter New Root Password Re-enter new password: <== Re-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: No <== Already high secure enough Using existing password for root. Change the password for root ? ((Press y|Y for Yes, any other key for No) : no <== Since the password is already changed in previous step, type no. ... 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? (Press y|Y for Yes, any other key for No) : yes <== Remove Anonymous user 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) : yes <== Disable remote root login 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) : yes <== Remove test database - 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) : yes <== Reload Privilege Success. All done!
Work with MySQL Server
Login to MySQL server with the root user and its password.
mysql -u root -p
Output:
