Batch deployment of Zabbix-agent to Linux

What we use here is ansible to deploy zabbix-agent in batches. Of course, scripts can also be used to deploy on Linux.

Environment ansible:10.127.0.133agent1:172.168.0.4agent2:172.168.0.5 carries out key authorization authentication to realize secret-free login.

In order to facilitate the management of agent hosts by ansible, it is necessary to authenticate ansible and agent with public key to achieve secret-free login.

Create a template file that contains variable variables in agent, such as hostname and server address

Ansible-playbook-I / etc/ansible/hosts / etc/ansible/linux-agent.yml

You can see that playbook has been executed successfully. Next, you can take a look at the configuration file of agent.

As you can see, the variables in the agent configuration file have also been modified

Create auto-discovery rules to automatically discover deployed hosts and add monitoring items to create automatic discovery rules

Add an autodiscover action

Configure actions after discovery

You can see that the auto-discovery rule is in effect and the Linux-OS template is linked

Batch deployment of Zabbix-agent to Windows

Batch deployment under Windows can be carried out through configuration management tools or domain controllers. Here I use ansible to batch deploy Windows hosts.

Environment ansible:10.127.0.133Windows server2012:172.168.0.6 depends on environment ansible depends on pywinrm > = 0.3.0

Pywinrm can be installed using pip by executing the following command

Pip install pywinrm > = 0.3.0Windows depends on PowerShell 3.0NET Framework 4.0 +

I use 2012 here. The above environment does not need to be configured. If you are using a server2008 or lower version that needs to be upgraded before you can use it, for more information about the upgrade, please visit the official ansible documentation to view it.

Install the winrm memory patch

Since ansible controls Windows not using ssh protocol, but using Windows's winrm service, winrm has an error that limits the amount of memory available, which needs to be fixed by installation script

Execute the following command on powershell

$url = "https://raw.githubusercontent.com/jborean93/ansible-windows/master/scripts/Install-WMF3Hotfix.ps1"$file =" $env:temp\ Install-WMF3Hotfix.ps1 "(New-Object-TypeName System.Net.WebClient). DownloadFile ($url, $file) powershell.exe-ExecutionPolicy ByPass-File $file-Verbose opens winrm service port and agent service port on the firewall

You can view the current listening port of winrm by executing the following command on powershell

Winrm enumerate winrm/config/Listener

Winrm service defaults to port 5985, while zabbix-agent uses port 10050, so you need to open ports 5985 and 10050 on the firewall or turn off the firewall directly

Download Windows-agent 's package

First of all, you need to download the Windows-agent package and decompress it to the ansible host.

Download address: https://www.zabbix.com/download_agents

Add host information in ansible/hosts

You need to specify the configuration information for connecting to Windows in hosts. Ntlm authentication is used by default. If you want to get more information about winrm authentication, you can visit https://docs.ansible.com/ansible/latest/user_guide/windows_winrm.html.

You can see that playbook has been successfully executed. Check the service of Windows. Zabbix-agent has also been started.
