Ensuring the Server is Up to date

Before proceeding, let us ensure that our OpenSUSE server is up to date. Use this command to update the server packages:

sudo zypper ref
sudo zypper up -y

Next, let us install common packages that we will need in our tutorial

sudo zypper in curl

Installing Mysql 8 server

Now that our packages are updated, we can proceed to install mysql server. The mysql server packages are not found in the default repositories of OpenSUSE, so we need to set up Mysql Community repositories before proceeding. Use this command to download the reposirory installation package:

> curl -LO https://dev.mysql.com/get/mysql80-community-release-sl15-3.noarch.rpm
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0
100 29772  100 29772    0     0  29891      0 --:--:-- --:--:-- --:--:-- 57034

Next, install the rpm package:

sudo zypper install -y ./mysql80-community-release-sl15-3.noarch.rpm

Now refresh the repositories to update the newly added mysql community repos:

sudo zypper ref

Use this command to check the info of the listed package to confirm that it provides the mysql version that we want:

> sudo zypper info mysql-community-server

Starting and enabling mysql service

Up to this point we managed to install the mysql service in our system. The service will not be started by default, so we will have to start by issuing the following command:

sudo systemctl start mysql

To enable the service to start on reboots, use this command:

sudo systemctl enable mysql

Now check the status of the service to confirm that it is actually running:

> sudo systemctl status mysql
● mysql.service - MySQL Server
     Loaded: loaded (/usr/lib/systemd/system/mysql.service; enabled; vendor preset: disabled)
     Active: active (running) since Tue 2021-11-02 03:00:27 UTC; 31s ago

The Active: active (running) since ... indicates that the service is up and running.

To view the MySQL 8 service log as follows using the journalctl command:

$ sudo journalctl -u mysql -xe
$ sudo tail -f /var/log/mysql/mysqld.log

Securing mysql installation

When the server is started for the first time, the server is initialized, and the following happens (if the data directory of the server is empty when the initialization process begins):

The SSL certificate and key files are generated in the data directory.
The validate_password plugin is installed and enabled.
A superuser account 'root'@'localhost' is created. A password for the superuser is set and stored in the error log file. To reveal it, use the following command:

> sudo grep 'temporary password' /var/log/mysql/mysqld.log
2021-11-02T03:00:23.175267Z 6 [Note] [MY-010454] [Server] A temporary password is generated for root@localhost: nGbo0jV#-OZZ

Change the root password as soon as possible by logging in with the generated, temporary password and set a custom password for the superuser account:

> mysql -u root -p
Enter password:

Testing MySQL Installation

Let us check mysql version with this command:

> mysql -V
mysql  Ver 8.0.27 for Linux on x86_64 (MySQL Community Server - GPL)

Now you can Login as the root user and the password specified above.

> mysql -u root -p
