Monitoring FileMaker Server by Installing Zabbix from Scratch

By September 11, 2019 September 16th, 2019 One Comment

This post is one in a series of guides that walk you through installing, configuring, and using Zabbix to monitor your FileMaker servers:

This guide will walk you through installing Zabbix Server. These steps assume you are somewhat proficient with Linux and the use of the command line or that you are willing to expand your skill set in this area. If this does not describe you, see the guide (2a – Zabbix as an Appliance) about using the Zabbix Server Appliance.

Choose Your Linux

Zabbix Server only runs on Linux, so we will have to pick a flavor of Linux we are comfortable with that is supported by Zabbix.

The Zabbix download page guides you neatly through the available choices of operating systems, versions of the chosen operating system, and backend-databases you want Zabbix Server to use to store its data:

Figure 1. Zabbix download

We chose CentOS, because it is also the operating system used for FileMaker Cloud, so whatever skills we pick up working with CentOS will serve us well both in working with the underpinnings of Zabbix Server and FileMaker Cloud. CentOS is also the operating system used in FileMaker Inc’s installation guide.

Note that the white paper that FileMaker Inc. published with the release of FileMaker 18 back in May of 2019 uses Zabbix Server version 3.x. The current version of as July 2019 is Zabbix 4.2 and its installation instructions are just slightly different. But the FMI guide is still a good reference.

For complete reference, the official installation guide is here:

and the one that FileMaker Inc has put together:

Between those two and this guide you are reading now, you should have all the information you need to get to a successful Zabbix Server installation.

Selecting the OS, version, and database on the Zabbix download page, update the command line information further down on the page that you need for the installation of Zabbix Server and its components:

Screenshot of the updated command line information

Figure 2. Updated command line information

Those steps assume that you already have a running Linux server of your chosen version so that you can copy and paste these commands into the command line terminal. Let’s take a step back and get one up and running.

There are a couple of different ways to get a running CentOS depending on whether you want it on-premise on physical hardware, on-premise as a virtual machine, or in the cloud.

Choose Your Location

For an on-premise install on physical hardware, you can grab the ISO installer directly from

Figure 3. Download CentOS

You can also use that ISO image to install it on-premise as a virtual machine. Or, if you want to cut out a few steps, you can download a pre-built virtual machine image from

Figure 4. Pre-built virtual image from CentOS

Setting Up CentOS On AWS

If you prefer a cloud server, pre-built images are available as well in the cloud provider’s market place. For AWS, provides an official instance for CentOS 7:

Screenshot of downloading the pre-built image for AWS

Figure 5. Pre-built image for AWS

The default instance type is a t2.micro (one virtual CPU and 1GB of RAM with 8GB of disk space), which is very cheap and more than capable of handling a Zabbix server monitoring multiple FileMaker Server hosts.

For this guide, we will use AWS, since it is easy to spin up a new instance (and abandon it) without having to make changes to our in-house infrastructure.

Once you go through the few steps required in AWS to have the machine launched, you will see it in your EC2 console. The “Name” column will be empty initially. I named it centOS7:

Screenshot of the EC2 console

Figure 6. EC2 console

The first thing we will do is click on the security group at the bottom of that screenshot to view and update the AWS ‘firewall’ so that we can use SSH to remote into the instance.

Specifically, we want to work with the “inbound rules.” By default, there will be none, so we will add the ones that we need:

  • Port 22 for SSH
  • Port 10051 for incoming data from the Zabbix agents that we will deploy later
  • Ports 80 and 443 for access to the browser-based Zabbix admin console

Figure 7. Set up the inbound rules

SSH To Server

At this point, we have a working Linux server. To connect to it, open your favorite SSH client (on macOS I am just using Terminal) and issue the proper SSH command:

ssh -i /Users/wimdecorte/Documents/projects/ETS18/zabbix_resources/wim_ets_15.pem

The path to the .pem file is required by AWS to allow SSH connections. “centos” is the default username for CentOS, and what comes after the @ is the public IP address or DNS name of your Linux server.

The first time you log in you will be asked for confirmation to connect and then will see the command prompt of an SSH session on your Linux server.

Screenshot of the command prompt of an SSH session

Figure 8. Command prompt of an SSH session

Install nano

The very first thing we will do is install “nano,” our favorite Linux text editor.

Type in:

sudo yum install nano

(yum stands for YellowDog Updater, Modified and is the CentOS default software manager. It is used to install new software and system updates).

As with all installations and updates, you will see a bit of an overview of what will happen, and you will be asked to confirm with “Y” that you want to proceed:

Screenshot of command line - type Y to proceed

Figure 9. Type “Y” to proceed

A few seconds later, we will be finished:

Screenshot showing Nano install is complete

Figure 10. Nano install is complete

SELinux Configuration Change

Second on our to-do list is to change a security setting in CentOS’s default configuration. By default, CentOS has SELinux enabled, which will get in the way of Zabbix Server functioning properly, so we need to adjust it:

Type in:

sudo nano /etc/selinux/config

Change the line that starts with “SELINUX” to read “SELINUX=permissive”

Screenshot of command line with line changed to "SELINUX=permissive"

Figure 11. Line changed to “SELINUX=permissive”

Press control-o and then enter to save the changes and control-x to quit the text editor.

Install Zabbix

Now we can go back to the instructions on the Zabbix download page that tell us how to install Zabbix Server:

Install Zabbix server

Figure 12. Install Zabbix Server

The first set of commands is basically telling ‘yum’ where the installers are located and to clean its internal database of available software locations.

Remember to run all of these commands as ‘super user’ by prefixing them with ‘sudo’. The first command will look like this:

Screenshot of command line showing command prefixed with "sudo"

Figure 13. Prefix all commands with “sudo”

The result of running the first two commands will look like this:

Screenshot of command line after running commands under "a. Install Zabbix repository"

Figure 14. After running commands under “a. Install Zabbix repository”

The third command on the Zabbix downloads page (under b) is where the actual installation happens:

sudo yum -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent

That one will run for a little while, install everything needed, and report back what it has done:

Screenshot of command line showing what has been done

Figure 15. Showing what has been done

Install MySQL

The next step is to configure the underlying MySQL (c and d on the Zabbix downloads page). But this is where the instructions may fail; MySQL is likely not installed at this point yet. You can try the command, but if an error comes back, follow the steps below to install MySQL:

Add the MySQL 8.0 repository to your server:

sudo yum install

Then install MySQL itself:

sudo yum -y install mysql-community-server

This one is a fairly hefty download and will take a while. After it is installed, start the MySQL service:

sudo systemctl start mysqld

Enable it to auto-start when the machine starts:

sudo systemctl enable mysqld

At any time, you can check if MySQL is running by using this command:

sudo systemctl status mysqld

When all is well, you will see an output from that ‘status’ command, confirming MySQL is up and running

Screenshot of MySQL up and running

Figure 16. MySQL up and running

MySQL installs with a temporary password that we need to grab before we do anything else. To do this, type in:

sudo nano /var/log/mysqld.log

and make note that the master user is ‘root’ with the password listed there.

Figure 17. Make note of the temporary password generated for master user

Hit control-x to quit the text editor.

Create the Zabbix Database

Now we are ready to resume our Zabbix installation following the step c instructions on the Zabbix downloads page to create the required database:

The first command is to enter ‘mysql mode’:

sudo mysql -uroot -p

At the password prompt, use the password that you retrieved earlier. After doing so, you will find yourself at a MySQL prompt.

Screenshot of MySQL prompt

Figure 18. Use the temporary password

Before we execute the commands listed on the Zabbix page, we need to change the password for the root user, since that temporary password cannot be used beyond this point. (The commands listed in step c will fail if you try.)

Type in:

alter user root@localhost identified by 'someNewPassword';

The new password is in-between the single quotes. Don’t forget to add the “;” at the end. This is how MySQL knows you are done with the command.

Screenshot of the new password

Figure 19. Temporary password is replaced

Now type in (or copy/paste) the first of the three separate MySQL commands of step c to create the database named “zabbix..”

Screenshot of "c. Create initial database" to create the database named "zabbix"

Figure 20. Create a database named “zabbix”

Before we do the next command, we actually have to create the Zabbix user in MySQL. Older versions of MySQL allow you to use the GRANT command to both create the user and assign rights to that user, but that is no longer supported in the newer version of MySQL (versions 8+).

Type in the following to create a MySQL “zabbix” user with a password you specify:

CREATE USER zabbix@localhost IDENTIFIED WITH mysql_native_password BY ‘MyOtherN3wP@ssword’;

Then instead of the command shown in the Zabbix instructions, use this slightly modified one to grant rights to the “zabbix” database for the “zabbix” user:

Screenshot of granting rights to the "zabbix" database for the "zabbix" user

Figure 21. Grant rights to the “zabbix” database for the “zabbix” user

The last command is easy and just drops out of the MySQL mode and back into Linux:

Screenshot of quitting MySQL and returning back into Linux

Figure 22. Quit MySQL and return back into Linux

The last item in step c is to import the schema for the “zabbix” database:

sudo zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p Zabbix
Screenshot of command line to import schema for the "zabbix" database

Figure 23. Import schema for the “zabbix” database

Note that the password requested here is for the newly created “zabbix” user.

Configure Zabbix Server

The next step in the Zabbix instructions calls for an edit to the Zabbix config file to make sure that Zabbix knows the MySQL password for the “zabbix” user:

Screenshot of d. Configure the database for Zabbix server to edit the Zabbix config file

Figure 24. Edit the Zabbix config file

Type in:

sudo nano /etc/zabbix/zabbix_server.conf

to open the Zabbix configuration file and scroll down to the entry for the database password:

Screenshot pointing to the "DBPassword=" line

Figure 25. Scroll to entry for the database password

Remove the “#” at the start of the line and add the password for the Zabbix MySQL user.

Screenshot showing the "#" symbol removed from start of the line

Figure 26. # symbol removed from the start of the line

Hit control-o and then enter to save the change and then control-x to quit nano.

At this point, much of the heavy lifting is done; the next step listed on the Zabbix download page is to update the time zone that will be used by Zabbix:

Screenshot of updating the time zone

Figure 27. Update the time zone

Type in

sudo nano /etc/httpd/conf.d/zabbix.conf

and scroll down to the time zone setting:

Screenshot of time zone setting

Figure 28. Time zone setting

And change it to your time zone. All supported time zones are listed here: Since we are on the East Coast, we changed it to America/New_York and removed the “#” at the start of the line:

Screenshot of "#" symbol removed from the start of the time zone line

Figure 29. # symbol removed from the start of the time zone line

Hit control-o and then enter to save the change and control-x to exit the text editor.

At this point, we can start the Zabbix server so that all the changes we have made take effect.

Screenshot of starting the Zabbix server

Figure 30. Start the Zabbix server

sudo systemctl restart zabbix-server zabbix-agent httpd

This command is actually restarting three services:

  1. The Zabbix server
  2. The Zabbix agent (each Zabbix server also monitors itself)
  3. The web server (https)

The 2nd command under step F ensures that all three of these services will auto-start when the machine restarts:

sudo systemctl enable zabbix-server zabbix-agent httpd

At this stage you will want to confirm that all three of these services are properly working by running these three checks:

sudo systemctl status zabbix-server
sudo systemctl status zabbix-agent
sudo systemctl status httpd

After each command you should see the service “in the green” next to ‘Active’:

Screenshot of the command with the service in green

Figure 31. Service is shown in green

Configure Zabbix Frontend

Going back to following the instructions shown on the Zabbix download page, we can now turn our attention to the Zabbix frontend by opening it in the browser:

Screenshot of opening Zabbix frontend in the browser

Figure 32. Open Zabbix frontend

Use the URL as indicated in your favorite browser, and you should see this:

Figure 33. Zabbix frontend in browser

“Next Step” brings us to an overview of the PHP pre-requisites, and if we did the installation correctly, everything here should be in the green:

Screenshot of the PHP prerequisites

Figure 34. PHP prerequisites

The following step is a confirmation of the Zabbix MySQL database. Enter the password here for the “zabbix” user that was added earlier on.

Screenshot of the "Configure DB Connection"

Figure 35. Enter the password for the “zabbix” user

Provide a name for your Zabbix installation:

Figure 36. Enter a name for the Zabbix installation

And you get one last chance to confirm all the settings:

Screenshot of the pre-installation summary

Figure 37. Pre-installation summary

And we are done:

Figure 38. Zabbix frontend installation completed

Now you can log in to the Zabbix admin console. The default credentials are username Admin (with a capital!) and password zabbix.

Congratulations, you have a fully functional Zabbix Server:

Next Steps

The next guides in this series explain how to install Zabbix agents on your FileMaker Servers (Part 4 – Zabbix Agents) and how to add those FileMaker Servers as hosts to monitor here in the Zabbix Server (Part 5 – Zabbix Configuration).

Disable MySQL Binary Logging

But there is one more important change that we want to make to MySQL before Zabbix Server starts to collect data.

We are running on an AWS t2.micro with 8GB of disk space, and at the end of the installation, we have just more than half of that disk space still available:

To check, type the following command and look at the Use % of the root directory (/):

Screenshot that shows disk space used

Figure 41. Disk space used

MySQL will collect binary logs (in folder /var/lib/mysql/) that will very quickly fill up that disk space. Those binary logs are only required if you intend to replicate this particular MySQL instance with others, and for our purpose, we do not. If you do want that default MySQL behavior, you will need to increase the disk size for this server.

In our deployment, we want to disable those binary logs.

Type in:

sudo nano /etc/my.cnf

and scroll down to the section indicated in Figure 42:

Screenshot that highlights the "# disable_log_bin" line

Figure 42. Scroll down to “# disable_log_bin”

Remove the “#” at the start of the line so that “disable_log_bin” becomes active:

Screenshot that shows the "#" symbol removed from the "disable_log_bin" line

Figure 43. Remove the “#” from the line

Hit control-o and then enter to save the changes and then control-x to quit the text editor.

Restart MySQL for the change to take effect:

sudo systemctl restart mysqld

On to the next guide and installing Zabbix Agents (3 – Zabbix Agents).


Between these two and this guide you are reading now, you should have all the information you need to get to a successful Zabbix Server installation.
