Step 1: Update the system
As you know, we start all software installation guides from the system update:
sudo apt update sudo apt -y full-upgrade
I always recommend you to perform a system restart after the upgrade is complete
Step 2: Install package dependencies
The following dependencies need to be installed on the system.All this can be used Easy Package management tools:
sudo apt install wget apt-transport-https gnupg2 libimlib2 libimlib2-dev
For Zammad to work properly, your system must use the correct language environment.
sudo apt install locales sudo locale-gen en_US.UTF-8 echo "LANG=en_US.UTF-8" | sudo tee /etc/default/locale
Install MariaDB database server:
sudo apt install mariadb-server
Use the following command to protect the security of the database installation server:
$ sudo mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and you haven't set the root password yet, the password will be blank, so you should just press enter here. Enter current password for root (enter for none): OK, successfully used password, moving on... Setting the root password ensures that nobody can log into the MariaDB root user without the proper authorisation. Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB 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? [Y/n] 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? [Y/n] y ... Success! By default, MariaDB 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? [Y/n] 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? [Y/n] y ... Success! Cleaning up... All done! If you've completed all of the above steps, your MariaDB installation should now be secure. Thanks for using MariaDB!
$ sudo vim /etc/mysql/mariadb.conf.d/50-server.cnf character-set-server = utf8mb4 collation-server = utf8mb4_general_ci
Restart the database server service:
