Setup Zabbix Server

1. Download zabbix-asset.

ā–¶ļø Clone Mata-Elang-Stable/zabbix-asset from GitHub to your server.

git clone https://github.com/mata-elang-stable/zabbix-asset.git ~/zabbix

2. Configure Zabbix server.

ā–¶ļø Edit .MYSQL_ROOT_PASSWORD to change the MySQL root password before initial setup.

nano ~/zabbix/env_vars/.MYSQL_ROOT_PASSWORD

ā–¶ļø Edit .MYSQL_PASSWORD to change the MySQL zabbix password before initial setup.

nano ~/zabbix/env_vars/.MYSQL_PASSWORD

3. Start Zabbix server.

ā–¶ļø Start the Zabbix Server.

sudo docker-compose -f ~/zabbix/docker-compose.yaml up -d

āœ… Confirm the containers are running.

sudo docker-compose -f ~/zabbix/docker-compose.yaml ps -a
Result

Setup Zabbix Agent

1. Install Zabbix agent.

ā–¶ļø Download the package.

wget -P ~/zabbix https://repo.zabbix.com/zabbix/6.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.2-4%2Bubuntu20.04_all.deb

ā–¶ļø Install the agent service.

sudo dpkg -i ~/zabbix/zabbix-release_6.2-4+ubuntu20.04_all.deb
sudo apt update && sudo apt -y install zabbix-agent

2. Configure Zabbix agent.

ā–¶ļø Edit zabbix_agentd.conf to configure the agent.

sudo nano /etc/zabbix/zabbix_agentd.conf
Configuration

šŸ”‘ Set the IP address of the Zabbix servers to ZABBIX_SERVER_IP_OR_NAME.

ā— The additional value 172.16.238.0/24, which was set on docker-compose.yaml, is required when the Zabbix server and agent run on the same host.

šŸ”‘ Set a hostname you like for the Zabbix agent to HOSTNAME_OF_AGENT. It's recommended to name differently for each agent to identify easily.

### Line 117: Set the IP or DNS names of the Zabbix server
#Server=127.0.0.1
Server=<ZABBIX_SERVER_IP_OR_NAME (e.g. 172.16.2.110)>,172.16.238.0/24

### Line 182: Set the hostname of the Zabbix agent.
#Hostname=Zabbix server
Hostname=<HOSTNAME_OF_AGENT (e.g. zabbix)>

3. Start Zabbix agent.

ā–¶ļø Enable service auto-start.

sudo systemctl enable zabbix-agent

ā–¶ļø Restart the agent service.

sudo systemctl restart zabbix-agent

āœ… Confirm the agent service is active.

systemctl status zabbix-agent

Dashboard Web UI

ā–¶ļø Open the following URL to see the Zabbix Dashboard.

  • URL: http://<ZABBIX_SERVER_IP_OR_NAME (e.g. 172.16.2.110)>/

šŸ”‘ The followings are what you should do for monitoring servers.

  1. Change Admin password.
  2. Change the time zone of the Admin user.
  3. Change the interface (IP address) of the host named "Zabbix server" from 127.0.0.1 to the actual address.
  4. Create hosts in configuration menu, as many as you need to monitor. (name, template, group, interface type, and IP address)
  5. Configure notifications. (media types, users, and actions)
How to change Admin password and time zone.

ā–¶ļø Go to [Administartion] -> [Users] -> Select "Admin" -> Change "Password" and "Time zone" -> [Update].
