Install MySQL, Nginx and Zabbix on Debian 11

At first, let’s update the packages:

# apt update

Next, download MySQL from the offical page or use wget command: Get the repo package

dpkg -i mysql-apt-config_0.8.20-1_all.deb
apt install  gnupg
dpkg -i mysql-apt-config_0.8.20-1_all.deb

When you attempt to install the package, it will ask you what product and version you want to install. Here you can select The MySQL version, Tools, Connectors (like MySQL Workbench), and preview packages. To select the version, hit the first option:

Select the version you will use. Once selected, it will bring you to the previous menu — press Ok button:

apt-get update

Install the MySQL Server using the command:

sudo apt-get install mysql-community-server

When apt finishes downloading, the installer will ask for a root password:

You have two options:

  1. Leave the password blank: the server will use unix sockets authentication. It means you can only access the server as a root user or as a user with sudo
  2. Set a password: the authentication method will be the same for other users.

If you set a password, the installer will ask which authentication plugin to use, strongly encrypted password (MySQL 8.x), or legacy method (MySQL 7.x and earlier).

Now, check the service status with systemctl:

systemctl status mysql.service
# systemctl status mysql.service

Next, run the command as a root user to safely configure the SQL service:

Enter password for user root:

VALIDATE PASSWORD COMPONENT 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 component?

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

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

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

Reloading the privilege tables will ensure that all changes

Login and Check the version

Check Nginx by IP address –

When using the Nginx web server, server blocks (similar to virtual hosts in Apache) can be used to encapsulate configuration details and host more than one domain on a single server. We will set up a domain called your_domain.

Install and configure Zabbix server for your platform
Install Zabbix repository

# wget
# dpkg -i zabbix-release_5.4-1+debian11_all.deb
# apt update

Install Zabbix server, frontend, agent

# apt install zabbix-server-mysql zabbix-frontend-php zabbix-nginx-conf zabbix-sql-scripts zabbix-agent2

c. Create initial database
Run the following on your database host.

# mysql -uroot -p
mysql> create database zabbix character set utf8 collate utf8_bin;
mysql> create user zabbix@localhost identified by 'Stx12WsaB';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> quit; 

On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password.

# zcat /usr/share/doc/zabbix-sql-scripts/mysql/create.sql.gz | mysql -uzabbix -p zabbix

Configure the database for Zabbix server. Edit file /etc/zabbix/zabbix_server.conf


Configure PHP for Zabbix frontend
Edit file /etc/zabbix/nginx.conf, uncomment and set ‘listen’ and ‘server_name’ directives.

nano /etc/zabbix/nginx.conf
# listen 80;
# server_name;

Start Zabbix server and agent processes and make it start at system boot.

# systemctl restart zabbix-server zabbix-agent2 nginx php7.4-fpm
# systemctl enable zabbix-server zabbix-agent2 nginx php7.4-fpm

Configure Zabbix frontend
Connect to your newly installed Zabbix frontend: http://server_ip_or_name
