MySQL 5.7 on Centos 7

MySQL is the go-to guy of databases. It is the bees knees, the one and the only — it is the mother, father, and son of the entire open source Relational Database Management System (RDBMS) universe. However, it has lost some of its tang when Oracle purchased it in 2010. I was one of those who strongly resented the acquisition but what the hey, business is business. Anyway, this post is all about MySQL5.7 installation in Centos 7. This shouldn’t be a problem if you are using Centos 6 or other Linux distributions but in Centos 7, it is a totally different ballgame because in the latest stable release of this distribution, MySQL is no more. It is replaced by MariaDB — a MySQL fork by the same guys who built MySQL in the first place. Now, you understand why I resent Oracle.

Here are the steps to install MySQL 5.7 in Centos 7:

Step 1: Download the rpm package

[root@lappy]$ wget

Step 2: Check whether or not the hash codes match

[root@lappy]$ md5sum mysql57-community-release-el7-9.noarch.rpm

This should be equal to the hashcode provided in the MySQL website (MD5: 1a29601dc380ef2c7bc25e2a0e25d31e).

Step 3: Install the package

[root@lappy]$ sudo rpm -ivh mysql57-community-release-el7-9.noarch.rpm

Step 4: Install MySQL

[root@lappy]$ sudo yum localinstall mysql-server

Step 5: Start MySQL 5.7

[root@lappy]$ service mysqld start

Step 6: Check out the MySQL 5.7 temporary root password

[root@lappy]$ sudo grep ‘temporary password’ /var/log/mysqld.log

Take note of the password at the end of the line.

Step 7: Configure MySQL 5.7

[root@lappy]$ sudo mysql_secure_installation

This will ask you to change the root password. Note: The strict implementation of MySQL requires 12 characters minimum with one uppercase character and a special character for passwords.

Step 8: Check the version

[root@lappy]$ mysql -u root -p –version

Step 9: Change the Root Password

mysql > ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘MyNewPass’;


mysql > SET PASSWORD FOR ‘root’@’localhost’ = PASSWORD(‘MyNewPass’);




Gammu requires MySQL not MariaDB to operate. Maybe in the future it will have connectors for the latter but for now, MySQL is the go to guy for Gammu implementations.
