Overview

This formula has been developed distributing declarations in different files to make it usable in most situations. It should be useful in scenarios ranging from a simple install of the packages (without any special configuration) to a more complex set-up with different nodes for agent, server, database and frontend.

Customization

First, see if providing pillar data is enough for your customization needs. That's the recommended way and should be enough for most cases. See that sometimes there's a key named extra_conf that's used to add arbitrary configuration lines in the templates provided.

When providing pillar data is not enough for your needs, you can apply the Template Override and Files Switch (TOFS) pattern as described in the documentation file TOFS_pattern.md.

The formula is designed to be independent from other formulas so you could use this in a non-100% salted environment (i.e. it's not required –although recommended– to use other formulas to provision other parts of a complete system).

Using RedHat EPEL repo Zabbix packages

If you want to use the EPEL repo packages, as the naming conventions are different, you need to tweak the default values of map.jinja to obtain the desired results. In short:

• Don't use the zabbix.agent.repo sls assuming that EPEL repos are already configured
• Override the map.jinja definitions using pillar values like this

zabbix:
  lookup:
    agent:
      pkg: zabbix22-agent
    server:
      pkg: zabbix22-server-mysql

Now you just have to use zabbix.agent.conf sls file and that's it.

Example of usage

Just as an example, this is a top.sls file to install a complete modular self-contained Zabbix system:

base:
  '*':
    - zabbix.agent.repo
    - zabbix.agent.conf

    - mysql.server.conf
    - mysql.client.conf
    - zabbix.mysql.conf
    - zabbix.mysql.schema

    - zabbix.server.repo
    - zabbix.server.conf

    - nginx.conf

    - php.fpm.repo
    - php.fpm.conf
    - php.fpm.mysql
    - php.fpm.bcmath
    - php.fpm.mbstring
    - php.fpm.gd
    - php.fpm.xml
    - php.fpm.opcache

    - zabbix.frontend.repo
    - zabbix.frontend.conf

You need the appropriate mysql, nginx and php formulas to complete the installation with this top.sls file.

If you are installing the zabbix agent for windows you will want to separate the pillar for windows from other linux and unix agents This is a pillar top.sls file example to separate windows and Ubuntu Zabbix agent pillar files

base:
  'os:Ubuntu':
    - match: grain
    - zabbix-agent-ubuntu

  'os:Windows':
    - match: grain
    - zabbix-agent-windows

Note

See the full Salt Formulas doc.

Available states

zabbix.agent

Installs the zabbix-agent package and starts the associated zabbix-agent service.

zabbix.agent.conf

Configures the zabbix-agent package.

zabbix.agent.repo

Configures official Zabbix repo specifically for the agent. Actually it just includes zabbix.repo and adds a requisite for the pkg state declaration

zabbix.frontend

Installs Zabbix frontend.

zabbix.frontend.conf

Configures the zabbix-frontend package. Actually you need to use other formulas for apache/nginx and php5-fpm to complete a working setup.

zabbix.frontend.repo

Configures official Zabbix repo specifically for the frontend. Actually it just includes zabbix.repo and adds a requisite for the pkg state declaration.

zabbix.mysql.conf

Creates database and mysql user for Zabbix.

zabbix.mysql.schema

Creates mysql schema for Zabbix.

zabbix.pgsql.conf

Creates database and PostgreSQL user for Zabbix.

zabbix.pgsql.schema

Creates PostgreSQL schema for Zabbix.

zabbix.proxy

Installs the zabbix-proxy package and starts the associated zabbix-proxy service.

zabbix.proxy.conf

Configures the zabbix-proxy package.

zabbix.proxy.repo

Configures official Zabbix repo specifically for the proxy. Actually it just includes zabbix.repo and adds a requisite for the pkg state declaration

zabbix.repo

Configures official Zabbix repo.

zabbix.server

Installs the zabbix-server package and starts the associated zabbix-server service.

zabbix.server.conf

Configures the zabbix-server package.

zabbix.server.repo

Configures official Zabbix repo specifically for the server. Actually it just includes zabbix.repo and adds a requisite for the pkg state declaration

zabbix.users

Declares users and groups that could be needed in other formulas (e.g. in the users formula to make an user pertain to the service group).

Testing

Linux testing is done with kitchen-salt.

Requirements

• Ruby
• Docker

$ gem install bundler
$ bundle install
$ bin/kitchen test [platform]

Where [platform] is the platform name defined in kitchen.yml, e.g. debian-9-2019-2-py3.

bin/kitchen converge

Creates the docker instance and runs the template main state, ready for testing.

bin/kitchen verify

Runs the inspec tests on the actual instance.

bin/kitchen destroy

Removes the docker instance.

bin/kitchen test

Runs all of the stages above in one go: i.e. destroy + converge + verify + destroy.

bin/kitchen login

Gives you SSH access to the instance for manual testing.
