For example, in Ubuntu, run "sudo apt install apache2 mysql-server mysql-client libapache2-mod-php7.4 php7.4-gd php7.4-ldap php7.4-odbc php7.4-xmlrpc php7.4-mbstring php7.4-bcmath php7.4-mysql php7.4-gmp php7.4-snmp php7.4-ssh2 php7.4-phpdbg" and in CentOS, execute "sudo yum install httpd mysql-server php php-mysql php-gd php-ldap php-odbc php-xmlrpc php-mbstring php-bcmath php-snmp php-ssh2".
  5. Start and enable the Apache and MySQL services using the appropriate commands, such as "sudo systemctl start apache2" and "sudo systemctl enable apache2" for Ubuntu, or "sudo systemctl start httpd" and "sudo systemctl enable httpd" for CentOS.
  6. Configure the necessary PHP settings for Zabbix by editing the PHP configuration file. For example, in Ubuntu, you can edit the file located at "/etc/php/7.4/apache2/php.ini".
  7. Download the Zabbix repository configuration package using the appropriate command for your distribution. For example, in Ubuntu, run "wget" and in CentOS, execute "sudo rpm -Uvh".
  8. Install the Zabbix server and frontend packages using the appropriate command for your operating system. For example, in Ubuntu, run "sudo apt install zabbix-server-mysql zabbix-frontend-php" and in CentOS, execute "sudo yum install zabbix-server-mysql zabbix-web-mysql".
  9. Import the Zabbix database schema by executing the appropriate command. For example, in Ubuntu, run "sudo mysql -u root -p zabbix < /usr/share/doc/zabbix-server-mysql/create.sql.gz".
  10. Configure the Zabbix server by editing the Zabbix server configuration file. For example, in Ubuntu, you can edit the file located at "/etc/zabbix/zabbix_server.conf".
  11. Start and enable the Zabbix server service using the appropriate commands. For example, in Ubuntu, execute "sudo systemctl start zabbix-server" and "sudo systemctl enable zabbix-server".
  12. Configure the Zabbix frontend by editing the Zabbix frontend configuration file. For example, in Ubuntu, you can edit the file located at "/etc/zabbix/apache.conf".
  13. Restart the Apache service to apply the changes by executing the appropriate command. For example, in Ubuntu, run "sudo systemctl restart apache2" and in CentOS, execute "sudo systemctl restart httpd".
  14. Finally, access the Zabbix frontend by opening a web browser and entering the Linode's IP address or domain name. Follow the on-screen instructions to complete the Zabbix installation process.

Please note that these steps are provided as a general guideline, and it's recommended to refer to the official documentation of your specific distribution and Zabbix version for more detailed instructions.

How to choose the appropriate Linode plan for Zabbix server installation?

Choosing the appropriate Linode plan for Zabbix server installation depends on several factors such as the expected number of monitored devices, data retention period, expected network traffic, and server resources required. Here are some considerations to help you choose the right plan:

  1. Monitor the number of devices: Determine the number of devices you want to monitor with Zabbix. Linode plans have different limits on the maximum number of simultaneous connections, so make sure your plan can handle your monitoring needs.
  2. Estimate server resources: Estimate the CPU and RAM resources required for Zabbix to run smoothly. Evaluate the system requirements of Zabbix and ensure that the Linode plan you choose provides sufficient resources to meet those requirements.
  3. Analyze expected network traffic: Consider the expected network traffic for your Zabbix server. If you anticipate high network traffic or a large number of checks, you may need more bandwidth and higher network transfer limits. Choose a Linode plan that offers adequate network resources for your monitoring needs.
  4. Data retention period: Determine how long you need to retain monitoring data. Logs and historical data can consume significant storage space. Consider the disk space offered by Linode plans and ensure it matches your data retention requirements.
  5. Scalability: Plan for future growth and scalability. If you anticipate expanding your monitoring capabilities in the future, choose a Linode plan that allows easy scalability, such as upgrading CPU, RAM, or disk space.
  6. Budget: Consider your budget constraints when choosing a Linode plan. Evaluate the cost of each plan against the resources provided and select the plan that offers the best value for your requirements.

It is recommended to consult the Linode documentation, contact their customer support, or seek advice from Zabbix experts for specific recommendations based on your monitoring needs.

How to download and install Zabbix server software on Linode?

To download and install Zabbix server software on Linode, you can follow these steps:

  2. Update your system's package manager by running the command: sudo apt update
  3. Install the required packages for Zabbix server: sudo apt install mysql-server apache2 php libapache2-mod-php php-mysql php-gd php-xml php-bcmath php-ldap php-mbstring php-mcrypt php-xmlrpc
  4. During the installation process, you will be prompted to enter a password for the MySQL root user. Provide a strong password and remember it for later use.
  5. Download the latest Zabbix server software package using wget: wget
  6. Install the downloaded package using dpkg: sudo dpkg -i zabbix-release_4.5-1+ubuntu20.04_all.deb
  7. Update the package manager again: sudo apt update
  8. Install Zabbix server, frontend, and agent packages: sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-agent
  9. Configure the Zabbix server to use the MySQL database: sudo nano /etc/zabbix/zabbix_server.conf In the configuration file, find the line that starts with "DBHost" and replace the value with "localhost". Uncomment the lines starting with "DBPassword" and "DBName". Save and exit the file.
  10. Import the initial database schema and data into MySQL: sudo zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | sudo mysql -u root -p zabbix Provide the MySQL root password you set earlier when prompted.

What is the minimum server requirements for installing Zabbix on Linode?

The minimum server requirements for installing Zabbix on Linode are as follows:

  • Operating System: Linode supports various Linux distributions, such as CentOS, Ubuntu, Debian, etc. You can choose the one you are most comfortable with or follow Zabbix's official installation guide for your preferred distribution.
  • CPU: A single CPU core should work fine for most small to medium-sized deployments. However, if you are monitoring a large number of devices or expecting heavy traffic, it is recommended to have a multi-core CPU for better performance.
  • RAM: At least 2 GB of RAM is the minimum requirement. However, as the size of your monitoring environment increases, it's advisable to allocate more RAM to ensure smooth operation.
  • Storage: The size of the storage depends on the number of devices being monitored and the retention period for data. Zabbix requires around 50 GB of disk space for a medium-sized environment.
  • Network: Ensure that your Linode instance has a stable and reliable network connection with adequate bandwidth to handle incoming and outgoing network traffic.
  • Optional: It is advisable to have a static IP address for your Linode server to simplify the configuration and management of the monitoring environment.

Keep in mind that these requirements can vary based on the size of your deployment and the specific monitoring needs. It's always recommended to allocate sufficient resources to ensure optimal performance and scalability.
