Log onto a server in school in Senso - log into ESXi

First create a new VM on the ESXi - Dont foget to turn on autostart

Call it Zabbix Proxy

It needs:

• 1 processor – 1 core

• 4GB Ram

• 50GB Hard drive

You will need the latest Ubuntu desktop ISO for 24.04.2 LTS – Make sure its the LTS.

Get from https://ubuntu.com/download/desktop - upload this to the datastore.

Select the ISO as a boot device and click connect – boot the new server

When booting from Ubuntu – select Try or install Ubuntu

Apart from selecting English UK keyboard layout – just next all the way through the install wizard – Select Install Ubuntu – interactive install – default – etc – until you get to Create Your Account

Create your name as intermadmin

Your computers name as three-digit name and Senso number – eg STC121   

(Case is important – whenever you type this later always remember it is UPPER case)

Set password to Migra....xxx

Keep tick for Require my password - Select UK time zone – Install

Wait 5 mins.... Restart now when it appears – it should automatically eject the ISO – but just check in ESXi and press enter to reboot Ubuntu

(If you are unsure of ESXi – there is an additional PDF on creating a VM in ESXi)

Log into Ubuntu

Skip through the welcome screens – we don’t want Pro...

First thing is to give the server a static address – preferably xxx.xxx.xxx.249 but check if this is free first – if it isn't - use another IP high up in the range

You may need to make changes to the filtering depending on which ISP. See Appendix B

Start – Settings – Network - The gear icon under the heading Wired – IPv4 – Manual

Set the IP address – netmask – Gateway and DNS – make sure you use a second DNS – so if the server goes down it can still communicate

Also, in settings – go to Power – Change screen blank to Never

Now open Firefox and make sure you can see the internet – if not –see appendix B about opening the firewalls and filtering. Once you can see the internet – Click Start – Terminal

If you cannot see bbc.co.uk - do not continue – it will not work.

Type

sudo –s

- then put in the Migrat.. password you specified earlier 

wget https://repo.zabbix.com/zabbix/7.2/release/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest_7.2+ubuntu24.04_all.deb

dpkg -i zabbix-release_latest_7.2+ubuntu24.04_all.deb

apt update

apt-get install mysql-server

- it will ask to install – click y

apt-get install zabbix-proxy-mysql zabbix-sql-scripts

- it will ask to install – click y

mysql -uroot -p

Password is 1nt….

create database zabbix_proxy character set utf8mb4 collate utf8mb4_bin;

create user intermit@localhost identified by "<TYPE 1n PASSWORD>";

- YOU NEED TO REPLACE <TYPE 1n PASSWORD> TO THE 1n...! PASSWORD

grant all privileges on zabbix_proxy.* to intermit@localhost;

set global log_bin_trust_function_creators = 1;

quit

cat /usr/share/zabbix/sql-scripts/mysql/proxy.sql | mysql --default-character-set=utf8mb4 -u intermit -p zabbix_proxy

Password is 1n…!

Be patient, this may take a while

mysql -uroot -p

Password is 1n…..

set global log_bin_trust_function_creators = 0;

quit

Now minimize the command window and open file explorer – in the top bar type /etc

Now open folder Zabbix – and right click on zabbix_proxy.conf - open with – Text Editor – and click the switch for Always use for this file type – Open

Now click open as administrator – Migra...

Now there is a few changes to make – first find # ProxyMode=0

On the line underneath copy this but without the # - so it should read

# ProxyMode=0

ProxyMode=0 

Next find Server=127.0.0.1

Change this to 

Server=zabbix.intermit.cloud

Now find Hostname=zabbix proxy  - Change this to 

Hostname=  -----  The name you called the computer when you installed it 

e.g. Hostname=STC121

Now find # DBHost=localhost

On the line underneath copy this but without the # - so it should read

# DBHost=localhost

DBHost=localhost

Now find DBUser=zabbix

Change it to DBUser=intermit

Now find # DBPassword=

On the line underneath copy this but without the # - so it should read

# DBPassword=

DBPassword=1n……    - YOU NEED TO CHANGE THIS TO THE PASSWORD

All done – Click the X in the top right – Save – enter the Migrat.. Password

go back to Terminal

ufw allow 10050/tcp

ufw allow 10051/tcp

systemctl restart zabbix-proxy

systemctl enable zabbix-proxy

Note – if you make any changes – you need to re run these two commands

TESTING

In terminal type

systemctl status zabbix-proxy

And it SHOULD look like this

⚫ zabbix-proxy.service - Zabbix Proxy

Loaded: loaded (/usr/lib/systemd/system/zabbix-proxy.service; enabled; preset: enabled)

Active: active (running) since Thu 2025-04-10 11:02:17 BST; 5min ago

Main PID: 9352 (zabbix_proxy)

Tasks: 1 (limit: 9440)

Memory: 3.6M (peak: 5.3M)

CPU: 37ms

CGroup: /system.slice/zabbix-proxy.service

L9352 /usr/sbin/zabbix_proxy -c /etc/zabbix/zabbix_proxy.conf 

If not –something is wrong somewhere

Some troubleshooting is in the appendix

Now we need to test this is working !

Minimize the command window and open file explorer – in the top bar type /var

Now navigate to log – zabbix and open zabbix_proxy.log 

Migrat.. Password

Client Setup

For each server to monitor

Download the latest client from Download Zabbix agents

Install this on the server 

Next, Accept, Next, Next 

Host name has to be unique – so for a K9SERVER put the three letters and senso number then hyphen – then server name e.g.

STC121-K9SERVER

CHT172-K9SERVER-APP

The Zabbix server IP/DNS is the proxy you have setup with the LOCAL IP 

Leave the port

Change the server or proxy for active checks also to the local proxy IP address

Tick the last box – add agent location to the PATH

Next, Install, Finish

Synology

To add a Synology to Zabbix – Log into the Synology

Go to Control Panel – Terminal and SNMP – Click on SNMP tab – Click Enable SNMP Service – then SNMP v3 Service

In username and password – enter

Intermit – Migra...

Tick Enable SNMP privacy

Set the SNMP privacy password also to Migra..

Click Apply – this is done on the Synology.

At this point – email Steve with the proxyname of the Ubuntu box and also the name of the clients that you have setup. 

For example

Proxy server = STC121

K9 Server = STC121-K9SERVER

K9 RDS = STC121-K9SERVER-RDS

Synology = STC121-Synology – 172.19.120.250 - I need the IP too

I will then add these and if you haven't already got one – I will email you your logins so you can access the dashboard and see your schools
