How to Install Zabbix 7.0 on Ubuntu 24.04 / 22.04 [Step-by-Step]

Zabbix server is installable on any Linux distribution, but in this tutorial, I will show you step-by-step how to install and optimize the latest Zabbix 7 LTS release on Ubuntu 24.04 (Noble), 22.04 LTS (Jammy Jellyfish) / 20.04 (Focal).

Zabbix is 100% free open-source ultimate enterprise-level software designed for monitoring availability and performance of IT infrastructure components. You can read a case-study about Zabbix popularity and find out more about open-source movement in this article.

Enough of talk lets do some work! First, we will install and configure Zabbix server, then a database and lastly the frontend – check the picture bellow for a better understanding of Zabbix architecture.

This guide is for installing Zabbix monitoring system (Server) on Ubuntu, while guide for installing Zabbix-proxy on Ubuntu can be found on this link.

Step 1: Install Zabbix server, frontend, and agent

Note: You need to log in as a root user on your Linux server with “su -” or use “sudo” to successfully execute commands used in this tutorial.

Install Zabbix 6 .deb package on your Ubuntu OS (24.04, 22.04, 20.04, 18.04 and 16.04 are supported).

Zabbix 7.0 LTS version (supported until 	June 31, 2029)
wget$(lsb_release -rs)_all.deb
sudo dpkg -i zabbix-release_7.0-1+ubuntu$(lsb_release -rs)_all.deb
sudo apt update
sudo apt -y install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent

You can find more information about Zabbix’s life cycle and release policies on the official website.

Step 2: Configure database

In this installation, I will use password rootDBpass as root password and zabbixDBpass as Zabbix password for DB. Consider changing your password for security reasons.

a. Install MariaDB 10.11

In your terminal, use the following command to install MariaDB 10.11 (supported untill 2028).

sudo apt install software-properties-common -y
curl -LsS -O 
sudo bash mariadb_repo_setup --mariadb-server-version=10.11
sudo apt update 
sudo apt -y install mariadb-common mariadb-server-10.11 mariadb-client-10.11

NOTE: If you get error on Ubuntu 24.04: “The repository ‘ noble Release’ does not have a Release file. [error] Failed to add trusted package signing keys” then use these commands instead of those above:

sudo rm /etc/apt/sources.list.d/mariadb.list
curl -fsSL | sudo gpg --dearmor -o /usr/share/keyrings/mariadb-archive-keyring.gpg
echo "deb [signed-by=/usr/share/keyrings/mariadb-archive-keyring.gpg] mantic main" >> /etc/apt/sources.list
apt update
apt install mariadb-server

Once the installation is complete, start the MariaDB service and enable it to start on boot using the following commands:

sudo systemctl start mariadb
sudo systemctl enable mariadb

b. Reset root password for database

Secure MySQL/MariaDB by changing the default password for MySQL root, I will change it to “rootDBpass”:

sudo mysql_secure_installation
Enter current password for root (enter for none): Press Enter
Switch to unix_socket authentication [Y/n] y
Change the root password? [Y/n] y
New password: <Enter root DB password, I will set "rootDBpass">
Re-enter new password: <Repeat root DB password, I will set "rootDBpass">
Remove anonymous users? [Y/n]: Y
Disallow root login remotely? [Y/n]: Y
Remove test database and access to it? [Y/n]:  Y
Reload privilege tables now? [Y/n]:  Y

c. Create database

sudo mysql -uroot -p'rootDBpass' -e "create database zabbix character set utf8mb4 collate utf8mb4_bin;"
sudo mysql -uroot -p'rootDBpass' -e "create user 'zabbix'@'localhost' identified by 'zabbixDBpass';"
sudo mysql -uroot -p'rootDBpass' -e "grant all privileges on zabbix.* to zabbix@localhost identified by 'zabbixDBpass';"

d. Import initial schema and data.

Import database shema for Zabbix server (could last up to 5 minutes):

sudo zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p'zabbixDBpass' zabbix

e. Enter database password in Zabbix configuration file

Open zabbix_server.conf file with command:

sudo nano /etc/zabbix/zabbix_server.conf

and add database password in this format anywhere in file:


Save and exit file (ctrl+x, followed by y and enter).

Step 3: Configure firewall

If you have a UFW firewall installed on Ubuntu, use these commands to open TCP ports: 10050 (agent), 10051 (server), and 80 (frontend):

ufw allow 10050/tcp
ufw allow 10051/tcp
ufw allow 80/tcp
ufw reload

Step 4: Start Zabbix server and agent processes

sudo systemctl restart zabbix-server zabbix-agent 
sudo systemctl enable zabbix-server zabbix-agent

Step 5: Configure Zabbix frontend

Connect to your newly installed Zabbix frontend using URL “http://server_ip_or_dns_name/zabbix” to initiate the Zabbix installation wizard. 

In my case, that URL would be “” because I have installed Zabbix on the server with IP address (you can find the IP address of your server by typing “ip a” command in the terminal).

Basically, in this wizard you only need to enter a password for Zabbix DB user and just click “Next step” for everything else. In this guide, I have used a zabbixDBpass as a database password, but if you set something else, be sure to enter the correct password when prompted by the wizard.

1. Installation step: Welcome screen

If you get the error “zabbix Locale for language “en_US” is not found on the web server. Tried to set: en_US, en_US.utf8, en_US.UTF-8, en_US.iso885915, en_US.ISO8859-1” then use this command to fix it:

apt-get install -y locales && echo 'en_US.UTF-8 UTF-8' >> /etc/locale.gen && locale-gen && service apache2 restart
3. Installation step: Configure DB connection
4. Installation step: Configure Zabbix server
5. Installation step: Pre-installation summary
6. Installation step: Finish
6. Installation step: Finish

That’s it, you have installed Zabbix monitoring system!

Step 6: Login to frontend using Zabbix default login credentials

Use Zabbix default admin username “Admin” and password “zabbix” (without quotes) to login to Zabbix frontend at URL “http://server_ip_or_dns_name/zabbix” via your browser.


In my example, I have installed Zabbix on server so I will enter in my browsers URL field (you can find the IP address of your server by typing “ip a” command in the terminal)

You have successfully installed Zabbix 7 on Ubuntu and now you can monitor anything!
No need to change anything else as other steps are optional.

How to create MySQL partitions on History and Events tables
Managing Zabbix / MySQL / Apache service

Step 7: Optimizing Zabbix Server (optional)

Don’t bother with this optimization if you are monitoring a small number of devices, but if you are planning to monitor a large number of devices then continue with this step.

Open “zabbix_server.conf” file with command: “sudo nano /etc/zabbix/zabbix_server.conf” and add this configuration anywhere in file:


Save and exit file (ctrl+x, followed by y and enter).

This is not a perfect configuration, keep in mind that you can optimize it even more. Let’s say if you don’t use ICMP checks then set the “StartPingers” parameter to 1 or if you don’t use active agents then set “StartTrappers” to 1 and so on. You can find out more about the parameters supported in a Zabbix server configuration file in the official documentation.

If you try to start the Zabbix server you may receive an error “[Z3001] connection to database 'Zabbix' failed: [1040] Too many connections” in the log “/var/log/zabbix/zabbix_server.log” because we are using more Zabbix server processes than MySQL can handle. We need to increase the maximum permitted number of simultaneous client connections and optimize MySQL – so move to the next step.

Step 8: Optimizing MySQL / MariaDB database (optional)

a. Create custom MySQL configuration file

Create file “10_my_tweaks.cnf" with “sudo nano /etc/mysql/mariadb.conf.d/10_my_tweaks.cnf” and paste this configuration:

max_connections                = 404
innodb_buffer_pool_size        = 800M

innodb-log-file-size           = 128M
innodb-log-buffer-size         = 128M
innodb-file-per-table          = 1
innodb_buffer_pool_instances   = 8
innodb_old_blocks_time         = 1000
innodb_stats_on_metadata       = off
innodb-flush-method            = O_DIRECT
innodb-log-files-in-group      = 2
innodb-flush-log-at-trx-commit = 2

tmp-table-size                 = 96M
max-heap-table-size            = 96M
open_files_limit               = 65535
max_connect_errors             = 1000000
connect_timeout                = 60
wait_timeout                   = 28800

Save and exit the file (ctrl+x, followed by y and enter) and set the correct file permission:

sudo chown mysql:mysql /etc/mysql/mariadb.conf.d/10_my_tweaks.cnf
sudo chmod 644 /etc/mysql/mariadb.conf.d/10_my_tweaks.cnf

Two things to remember!

Configuration parameter max_connections must be larger than the total number of all Zabbix proxy processes plus 150. You can use the command below to automatically check the number of Zabbix processes and add 150 to that number:

root@ubuntu:~ $ egrep "^Start.+=[0-9]"  /etc/zabbix/zabbix_server.conf  |  awk -F "=" '{s+=$2} END {print s+150}'

The second most important parameter is innodb_buffer_pool_size, which determines how much memory can MySQL get for caching InnoDB tables and index data. You should set that parameter to 70% of system memory if only database is installed on server.

However, in this case, we are sharing a server with Zabbix and Apache processes so you should set innodb_buffer_pool_size to 40% of total system memory. That would be 800 MB because my Ubuntu server has 2 GB RAM.

I didn’t have any problems with memory, but if your Zabbix proxy crashes because of lack of memory, reduce “innodb_buffer_pool_size” and restart MySQL server.

Note that if you follow this configuration, you will receive “Too many processes on the Zabbix server” alarm in Zabbix frontend due to the new Zabbix configuration. It is safe to increase the trigger threshold or turn off that alarm (select “Problems” tab → left click on the alarm → select “Configuration” → remove the check from “Enabled” → hit the “Update” button)

Learn more about database optimization in the tutorial: How to optimize Zabbix database?

b. Restart Zabbix Server and MySQL service

Stop and start the services in the same order as below:

sudo systemctl stop zabbix-server
sudo systemctl stop mysql
sudo systemctl start mysql
sudo systemctl start zabbix-server

Step 9: Create MySQL partitions on History and Events tables

Zabbix’s housekeeping process is responsible for deleting old trend and history data. Removing old data from the database using SQL delete query can negatively impact database performance. Many of us have received that annoying alarm “Zabbix housekeeper processes more than 75% busy” because of that.

That problem can be easily solved with the database partitioning. Partitioning creates tables for each hour or day and drops them when they are not needed anymore. SQL DROP is way more efficient than the DELETE statement.

You can partition MySQL tables in 5 minutes using this simple guide.

Step 10: How to manage Zabbix / MySQL / Apache service

Sometimes you will need to check or restart Zabbix, MySQL or Apache service – use commands below to do that.

Zabbix Server
sudo systemctl <status/restart/start/stop> zabbix-server

MySQL Server
sudo systemctl <status/restart/start/stop> mysql

Apache Server
sudo systemctl <status/restart/start/stop> apache2

Zabbix Agent
sudo systemctl <status/restart/start/stop> zabbix-agent 

Step 11: Upgrade between minor versions

I wrote about these upgrade procedures in my post about Zabbix upgrade. Zabbix’s team releases new minor versions at least once a month. The main purpose of minor upgrades is to fix bugs (hotfix) and sometimes even bring new functionality. Therefore, try to do a minor upgrade of Zabbix at least once a month.

There is no need for backups when doing a minor upgrade, they are completely safe. With this command you can easily upgrade smaller versions of 7.0.x (for example, from 7.0.1 to 7.0.3):

sudo apt install --only-upgrade 'zabbix*'

And restart Zabbix server afterward:

sudo systemctl restart zabbix-server

  1. Hello,
    Thank you so much for this manual !
    Despite several installation attempts I always have the following message when I launch my web interface to finalize the installation : Access denied for user ‘admin’@’localhost’ (using password: YES)

    And, I don’t undestand why zabbix account is created under “user.mysql” database instead of “users.zabbix” database after its creation ?.

    Thank you in advance.

  2. Hello good morning how are you?
    So, I have a zabbix version 5.2.6, I installed a new version 6.2.3 on another server.. Is there a way to import the entire database from version 5.2.6 to 6.2.3???

    • Yes. Upgrade 5.2.6 to 6.2.3, dump DB to file, copy file to the new 6.2.3 server and import DB.

  3. Thanks for the post, I have the following query, I hope you can help me please.
    I want to monitor 600 hosts, of which there will be approximately 28,000 triggers. I would like to know, based on your recommendation, what would be the best way to implement Zabbix, taking into account that it supports everything I want to monitor and gives it continuity.

    An example could be to create 2 Ubuntu servers, the first for Zabbix server and Database (Main), the second for Zabbix proxy.

    I will appreciate if you can help me. Thank you

    • You need a dedicated DB server, a good start would be 16G RAM and SSD. Zabbix server and frontend can be on the same server, that server doesn’t need a fast disk, just add at least 16G RAM. I think that 2 servers (DB & Server/Frontend) are enough for your environment. Later, you can always scale Zabbix and DB server vertically or add a proxy server if necessary.

  4. Thank you, an excellent guide for a rookie. Can you help, i keep getting the following error during the import

    sudo zcat /usr/share/doc/zabbix-sql-scripts/mysql/server.sql.gz | mysql -uzabbix -p’zabbixDBpass’ zabbix
    /usr/share/doc/zabbix-sql-scripts/mysql/server.sql.gz: No such file or directory

    When i browse to IP/zabbix/setup.php
    Details Cannot connect to the database.
    Unable to determine current Zabbix database version: the table “dbversion” was not found.

  5. Thanks for the guide. I have tried to install Zabbix 6.2 on ubuntu 22.04, and when I get to the install part I get an error or two. I have tried this with the guide on the zabbix site and same deal. Is there something I am missing?

    • hi
      The problem can be fixed by modifying the right file:
      nano /etc/dpkg/dpkg.cfg.d/excludes
      and adding the following line about Zabbix
      #… except zabbix
      Re-install the zabbix packages, and you should now see the file needed to continue

  6. Thank you very much,

    With help of your Step by Step guidance, I successfully manage to install Zabbix

  7. Hello Aldin,
    I hopo you’re fine!

    Your tutorial is perfect!
    I managed to learn perfectly how to install Zabbix Server.

    Congratulations on the excellent work.


  8. I am trying to create the db tables with Ubuntu 20.04 and Zabbix 5.4. This version doesn’t install the create.sql.gz scripts in /usr/share/doc/zabbix-server-mysql.

    I had to install one additional packages: zabbix-sql-scripts which creates a directory /usr/share/doc/zabbix-sql-scripts, which has sub-directories under it and contains the needed sql scripts to setup the db.

    The process need to be updated to include installing the extra package and also pulling the create.sql.gz from a different directory.

  9. Hey everyone, hi.
    I’m getting a bug from:
    DateTime::__construct(): Invalid date.timezone value ‘Africa/Angola’, we selected the timezone ‘UTC’ for now.

    I’m from Angola (country) and Africa as a continent.

  10. Thank you for this guide, I managed to setup a zabbix container on proxmox, using this awesoem guide. Have a great day.

  11. Hello
    i’ve installed Zabbix server and proxy following this guides on Ubuntu desktop 20.04 but my proxy is not able to reach server.

    someone can help me?

    • You have misconfigured the proxy configuration on the Zabbix frontend. Select “active” instead of “passive” mode.

  12. Iv used this article as a reference a few times and I greatly appreciate it, one thing iv managed to speculate on a few times is the following line.

    “Don’t bother with this optimization if you are monitoring a small number of devices, but if you are planning to monitor a large number of devices then continue with this step.”

    Now, since what a person considerins “a small number of devices” is very subjective, i was wondering if you could give some sort of indication when you would start optimizing.

    I have a project in the works where 50-70 switches(mixed cisco/hp) and about 20+ varity of devices(controllers for 400+ access points) etc

    Would you consider that a small or would you recommend optimizing? Despite the size it is pretty low in usage, so not a lot of traffic is generated.

    Thanks for sharing a article 🙂

    • It’s hard for me to define a number of devices that would define a small environment because one device can have a thousand items or you can have a thousand devices with one item. However, if you only use the out-of-box templates from the Zabbix and you don’t have more than 30 devices I would call that a small environment, everything above that requires optimization of the Zabbix server and potentially the database.

  13. Sir Thanks for such wonderful guideline to install Zabbix.

    Installation done Perfectly but Zabbix Server is not running and getting error in
    Administration -Queue –
    Connection to Zabbix server “localhost” refused. Possible reasons:
    1. Incorrect server IP/DNS in the “zabbix.conf.php”;
    2. Security environment (for example, SELinux) is blocking the connection;
    3. Zabbix server daemon not running;
    4. Firewall is blocking TCP connection.
    Connection refused

    Please help.


  14. Not sure if it’s the right way to go about it but I fixed the “sudo mysql_secure_installation : command not found” problem by installing the mysql client & server with “sudo apt install mysql-server mysql-client”.

    This appears to have worked although when I run the command, “sudo mysql_secure_installation” the response I get is:

    $ sudo mysql_secure_installation

    Securing the MySQL server deployment.

    Connecting to MySQL using a blank password.

    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?

    Press y|Y for Yes, any other key for No: y

    There are three levels of password validation policy:

    LOW Length >= 8
    MEDIUM Length >= 8, numeric, mixed case, and special characters
    STRONG Length >= 8, numeric, mixed case, special characters and dictionary file

    Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG:

    I killed that and tried again and was not asked about the “VALIDATE PASSWORD COMPONENT” and the rest followed your instructions provided up to the command:
    sudo mysql -uroot -p’rootDBpass’ -e “grant all privileges on zabbix.* to zabbix@localhost identified by ‘zabbixDBpass’;”
    The error was:
    mysql: [Warning] Using a password on the command line interface can be insecure.
    ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘identified by ‘zabbixDBpass” at line 1

    I used the same passwords as the instructions since this is just a test to see if I can get things working.


    • Looks like that you have installed a newer version of MySQL instead of MariaDB. In that case, is not necessary to put “identified by” part just “sudo mysql -uroot -p’rootDBpass’ -e “grant all privileges on zabbix.* to zabbix@localhost”;”

      • Thanks for the reply and explanation. I was running a VM so I just reverted and installed MariaDB. Everything works great. Awesome job!

  15. When I execute the command: sudo mysql_secure_installation
    I get an error: sudo: mysql_secure_installation: command not found

    I checked the installation of the packages and to the best of my knowledge they installed:
    sudo apt -y install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-agent

    I previously set up Zabbix on a Raspberry Pi and everything worked really well, thanks for the great instructions and information.


    • For some reason, Zabbix installation packages do not install MariaDB on Ubuntu 20.04. If you receive the error “mysql_secure_installation: command not found”, then you need to install MariaDB. I updated the tutorial, check out the section “Configure database”.

      • Thanks so much for the follow-up. I just built another instance on a Raspberry Pi and found the same problem which you have updated in your documentation. This did not happen a couple of weeks ago so I assume something [obviously] changed. No problem now that I know how to fix it.

  16. Hi,
    I am getting this error while sending a test email(gmail) notification:

    Connection to Zabbix server “localhost” refused. Possible reasons:
    1. Incorrect server IP/DNS in the “zabbix.conf.php”;
    2. Security environment (for example, SELinux) is blocking the connection;
    3. Zabbix server daemon not running;
    4. Firewall is blocking TCP connection.
    Connection refused

    Following are the parameters of zabbix.conf.php
    $ZBX_SERVER = ‘localhost’;
    $ZBX_SERVER_PORT = ‘10051’;
    $ZBX_SERVER_NAME = ‘ubuntu’;

    what should i do? I tried changed from localhost to my internet/dns ip…still didn’t worked out. And also i didn’t found any process on 10051 port. the servername is my hostname.

    Please help me out someone.

    • Check again file zabbix.conf.php
      ZBX_SERVER = ‘**your zabbix ip address or DNS name**’;
      ZBX_SERVER_PORT = ‘10051’;
      ZBX_SERVER_NAME = ‘**your zabbix hostname**’;

      After that, restart the Zabbix server.

      If that doesn’t help, then disable the firewall and SELinux temporarily and restart the Zabbix server to see if that couses problem.

  17. Thanks for your walkthrough. Does this need any prerequisites, like apache or mariadb being installed first? I get stuck at step 4-a. /etc/zabbix/apache.conf does not exist, so I can’t edit the lines you mention.

    • Maybe you are viewing old tutorial from the cache that is missing “zabbix-apache-conf” parameter from step 1:
      Just run the command:
      sudo apt -y install zabbix-apache-conf
