Zabbix

Zabbix Server

Pod

podman pod create --name zabbix -p 127.0.0.1:8080:8080 -p 10051:10051

Database

podman run --name zabbix-mysql -t \
    -e MYSQL_DATABASE="zabbix" \
    -e MYSQL_USER="zabbix" \
    -e MYSQL_PASSWORD="zabbix" \
    -e MYSQL_ROOT_PASSWORD="rootpass" \
    -v /mnt/mysql/:/var/lib/mysql/:Z \
    --restart=always \
    --pod=zabbix \
    -d docker.io/mysql:latest \
    --character-set-server=utf8 --collation-server=utf8_bin \
    --default-authentication-plugin=mysql_native_password

Application

Zabbix consists of multiple containers that need to be running.
First is the server itself.

podman run --name zabbix-server -t \
    -e DB_SERVER_HOST="127.0.0.1" \
    -e MYSQL_DATABASE="zabbix" \
    -e MYSQL_USER="zabbix" \
    -e MYSQL_PASSWORD="zabbix" \
    -e MYSQL_ROOT_PASSWORD="rootpass" \
    -e ZBX_STARTPOLLERS=50 \
    --pod=zabbix \
    -d docker.io/zabbix/zabbix-server-mysql:latest

Next, we need the webserver

podman run --name zabbix-web -t \
    -e ZBX_SERVER_HOST="127.0.0.1" \
    -e DB_SERVER_HOST="127.0.0.1" \
    -e MYSQL_DATABASE="zabbix" \
    -e MYSQL_USER="zabbix" \
    -e MYSQL_PASSWORD="zabbix" \
    -e MYSQL_ROOT_PASSWORD="rootpass" \
    --restart=always \
    --pod=zabbix \
    -d docker.io/zabbix/zabbix-web-nginx-mysql:latest

Finally, we will also install the agent as a container

podman run --name zabbix-agent \
    -e ZBX_SERVER_HOST="127.0.0.1,localhost" \
    --restart=always \
    --pod=zabbix \
    -d docker.io/zabbix/zabbix-agent:latest

The default user is Admin with password zabbix

Updating Server

Updating the server might fail for various reasons. Those I already encountered will be documented below.
NOTE: The server and proxy need to run the same version of zabbix to talk with one another

MARIADB: Missing permissions (log_bin_trust_function_creators)

From what I could find this error is thrown, when the specified user lacks super user privileges.
A workaround is enabling log_bin_trust_function_creators temporarily.
# podman exec -it zabbix-mysql bash
# mysql -u root -p and enter the root password
mysql> set global log_bin_trust_function_creators=1;

The setting will be reset to default after a restart of the database container.

Zabbix Proxy

ZBX_HOSTNAME has to be the same as the value configured on the zabbix server as the proxy name.

podman run --name zabbix-proxy \
    -p 10051:10051 \
    -e ZBX_SERVER_HOST="178.18.243.82" \
    -e ZBX_HOSTNAME="he1prx1" \
    -e ZBX_TLSCONNECT=psk \
    -e ZBX_TLSPSKIDENTITY="PSK Zabbix he1prx1" \
    -e ZBX_TLSPSKFILE="/mnt/zabbix/zabbix_agentd.psk" \
    -v /mnt/zabbix:/var/lib/zabbix/db_data \
    -v /mnt/zabbix:/mnt/zabbix \
    -d docker.io/zabbix/zabbix-proxy-sqlite3:latest

Updating Proxy

Updating the proxy will always fail when using the SQLite database, as upgrading is not supported for SQLite.
NOTE: The server and proxy need to run the same version of zabbix to talk with one another

Simply deleting/moving the old SQLite database and restarting the proxy is enough.
NOTE: History stored on the proxy will obviously be lost

Zabbix Agent

podman run --name zabbix-agent \
    -p 10050:10050 \
    -e ZBX_HOSTNAME="(hostname)" \
    -e ZBX_SERVER_HOST="(zabbix server/proxy)" \
    -d docker.io/zabbix/zabbix-agent:latest

XCP-ng

Use zabbix package from EPEL.
Zabbix server can handle the older agent fine See the Documentation on Compatibility
# yum install zabbix50-agent --enablerepo=epel

Edit /etc/zabbix_agentd.conf
haven't managed to make encryption work yet

Server=(Zabbix server ip)
ServerActive=(Zabbix server ip)
Hostname=he1xcp1
#TLSConnect=psk
#TLSAccept=psk
#TLSPSKIdentity=he1xcp1
#TLSPSKFile=/mnt/zabbix/zabbix_agentd.psk

Create the .psk file. Set the user and group to zabbix

Allow 10050/TCP on the firewall

nope
# yum install openssl11 --enablerepo=epel

Configuration

SMART monitoring

Smart monitoring is available using an official template

Requirements:

smartmontools > 7.1

Additionally, the zabbix user needs to have permission for running smartctl.
With sudo this can be accomplished without the user entering a password.

zabbix ALL=(ALL) NOPASSWD:/usr/sbin/smartctl

After that, add the SMART by Zabbix agent 2 template to the host
