Build Status

This is a role for installing and maintaining the zabbix-server.

This is one of the 'dj-wasabi' roles which configures your whole zabbix environment. See below for the complete list:

Upgrades

1.0.0

With this 1.0.0 release, the following is changed:

  • This repository will only contain all the actions that are needed for correctly configuring a Zabbix Server. All tasks regarding the frontend/webui of Zabbix has been transferred to the dj-wasabi.zabbix-web role.
  • All properties start with zabbix_ now. Example, property named server_dbuser is now zabbix_server_dbuser.

Requirements

Operating systems

This role will work on the following operating systems:

  • Red Hat

Installation

Installing this role is very simple: ansible-galaxy install dj-wasabi.zabbix-server

Please be aware that this role only installs the Zabbix Server and not the Zabbix Web. If you do want to have a Zabbix Web, please execute the following command: ansible-galaxy install dj-wasabi.zabbix-web

Role Variables

Main variables

The following is an overview of all available configuration default for this role.

Overall Zabbix

  • zabbix_version: This is the version of zabbix. Default: 3.4. Can be overridden to 3.2, 3.0, 2.4, or 2.2.
  • zabbix_repo_yum: A list with Yum repository configuration.
  • zabbix_repo: Default: zabbix
    • epel install agent from EPEL repo
    • zabbix (default) install agent from Zabbix repo
    • other install agent from pre-existing or other repo
  • zabbix_server_package_state: Default: present. Can be overridden to "latest" to update packages when needed.

Zabbix Server

  • zabbix_server_name: The name of the Zabbix Server.
  • zabbix_server_database: The type of database used. Can be: mysql or pgsql
  • zabbix_server_database_long: The type of database used, but long name. Can be: mysql or postgresql
  • zabbix_server_hostname: The hostname on which the zabbix-server is running. Default set to: {{ inventory_hostname }}
  • zabbix_server_listenport: On which port the Zabbix Server is available. Default: 10051
  • zabbix_server_dbhost: The hostname on which the database is running.
  • zabbix_server_dbname: The database name which is used by the Zabbix Server.
  • zabbix_server_dbuser: The database username which is used by the Zabbix Server.
  • zabbix_server_dbpassword: The database user password which is used by the Zabbix Server.
  • zabbix_server_dbport: The database port which is used by the Zabbix Server.
  • zabbix_server_database_creation: True / False. When you don't want to create the database including user, you can set it to False.
  • zabbix_server_install_recommends: True / False. False does not install the recommended packages that come with the zabbix-server install. Default true
  • zabbix_server_install_database_client: True / False. False does not install database client. Default true
  • zabbix_server_database_sqlload:True / False. When you don't want to load the sql files into the database, you can set it to False.
  • zabbix_server_dbencoding: The encoding for the MySQL database. Default set to utf8
  • zabbix_server_dbcollation: The collation for the MySQL database. Default set to utf8_bin

TLS Specific configuration

These variables are specific for Zabbix 3.0 and higher:

  • zabbix_server_tlsconnect: How the agent should connect to server or proxy. Used for active checks. Possible values:
    • unencrypted
    • psk
    • cert
  • zabbix_server_tlsaccept: What incoming connections to accept. Possible values:
    • unencrypted
    • psk
    • cert
  • zabbix_server_tlscafile: Full pathname of a file containing the top-level CA(s) certificates for peer certificate verification.
  • zabbix_server_tlscrlfile: Full pathname of a file containing revoked certificates.
  • zabbix_server_tlsservercertissuer: Allowed server certificate issuer.
  • zabbix_server_tlsservercertsubject: Allowed server certificate subject.
  • zabbix_server_tlscertfile: Full pathname of a file containing the agent certificate or certificate chain.
  • zabbix_server_tlskeyfile: Full pathname of a file containing the agent private key.

Database

There are some zabbix-server specific variables which will be used for the zabbix-server configuration file. These can be found in the defaults/main.yml file. There are 3 which need some explanation:

  #database_type: mysql
  #database_type_long: mysql
  zabbix_server_database: pgsql
  zabbix_server_database_long: postgresql
  [...]
  zabbix_server_dbport: 5432

There are 2 database_types which will be supported: mysql and postgresql. You'll need to comment or uncomment the database you would like to use and adjust the port number (server_dbport) accordingly (5432 is the default postgresql port). In example from above, the postgresql database is used. If you want to use mysql, uncomment the 2 lines from mysql and comment the 2 lines for postgresql and change the database port to the mysql one (default mysql port is 3306).

If you use mysql, then you should define mysql username, password and host to prepare zabbix database, otherwise they will be considered as their default value (and therefore, connecting to database will be considered as connecting to localhost with no password). The keys are below:

   zabbix_server_mysql_login_host
   zabbix_server_mysql_login_user
   zabbix_server_mysql_login_password

If you use pgsql, then you should define pgsql username, password and host to prepare zabbix database, otherwise they will be considered as their default value (and therefore, connecting to database will be considered as connecting to localhost with no password). The keys are below:

   zabbix_server_pgsql_login_host
   zabbix_server_pgsql_login_user
   zabbix_server_pgsql_login_password

Dependencies

For the databases you should find a role that suits your needs, as I don't want to force you for using a specific role. Before applying this Zabbix Server role, the database service should already be installed and running, and should be able to handle the modules in Ansible that belong to that database.

This role will not install a MySQL or PostgreSQL service.

This role will create a Zabbix user and a Zabbix database in the configured database type.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

- hosts: zabbix-server
  become: yes
  roles:
     - { role: dj-wasabi.zabbix-server, database_type: mysql, database_type_long: mysql }

Molecule

This role is configured to be tested with Molecule. You can find on these pages some more information regarding Molecule:
