Icinga 2 Web

Table of Contents

  1. Vagrant - Virtual development environment

Vagrant

The Icinga 2 Web project ships with a Vagrant virtual machine that integrates the source code with various services and example data in a controlled environment. This enables developers and users to test Livestatus, status.dat, MySQL and PostgreSQL backends as well as the LDAP authentication. All you have to do is install Vagrant and run:

vagrant up

Note that the first boot of the vm takes a fairly long time because you'll download a plain CentOS base box and Vagrant will automatically provision the environment on the first go.

After you should be able to browse localhost:8080/icinga2-web.

Icinga with IDOUtils using a MySQL database

Installation path: /usr/local/icinga-mysql

Services:

  • icinga-mysql
  • ido2db-mysql

Connect to the icinga mysql database using the following command:

mysql -u icinga -p icinga icinga

Access the Classic UI (CGIs) via localhost:8080/icinga-mysql. For logging into the Icinga classic web interface use user icingaadmin with password icinga.

Icinga with IDOUtils using a PostgreSQL database

Installation path: /usr/local/icinga-pgsql

Services:

  • icinga-pgsql
  • ido2db-pgsql

Connect to the icinga mysql database using the following command:

sudo -u postgres psql -U icinga -d icinga

Access the Classic UI (CGIs) via localhost:8080/icinga-pgsql. For logging into the Icinga classic web interface use user icingaadmin with password icinga.

MK Livestatus

MK Livestatus is added to the Icinga installation using a MySQL database.

Installation path:

  • /usr/local/icinga-mysql/bin/unixcat
  • /usr/local/icinga-mysql/lib/mk-livestatus/livecheck
  • /usr/local/icinga-mysql/lib/mk-livestatus/livestatus.o
  • /usr/local/icinga-mysql/etc/modules/mk-livestatus.cfg
  • /usr/local/icinga-mysql/var/rw/live

Example usage:

echo "GET hosts" | /usr/local/icinga-mysql/bin/unixcat /usr/local/icinga-mysql/var/rw/live

LDAP example data

The environment includes a openldap server with example data. Domain suffix is dc=icinga,dc=org. Administrator (rootDN) of the slapd configuration database is cn=admin,cn=config and the administrator (rootDN) of our database instance is cn=admin,dc=icinga,dc=org. Both share the password admin.

Examples to query the slapd configuration database:

ldapsearch -x -W -LLL -D cn=admin,cn=config -b cn=config dn
ldapsearch -Y EXTERNAL -H ldapi:/// -LLL -b cn=config dn

Examples to query our database instance:

ldapsearch -x -W -LLL -D cn=admin,dc=icinga,dc=org -b dc=icinga,dc=org dn
ldapsearch -Y EXTERNAL -H ldapi:/// -LLL -b dc=icinga,dc=org dn

This is what the dc=icinga,dc=org DIT looks like:

dn: dc=icinga,dc=org

dn: ou=people,dc=icinga,dc=org

dn: ou=groups,dc=icinga,dc=org

dn: cn=Users,ou=groups,dc=icinga,dc=org cn: Users uniqueMember: uid=jdoe,ou=people,dc=icinga,dc=rg uniqueMember: uid=jsmith,ou=people,dc=icinga,dc=rg uniqueMember: uid=jqpublic,ou=people,dc=icinga,dc=rg uniqueMember: uid=jroe,ou=people,dc=icinga,dc=rg

dn: cn=John Doe,ou=people,dc=icinga,dc=org cn: John Doe uid: jdoe

dn: cn=Jane Smith,ou=people,dc=icinga,dc=org cn: Jane Smith uid: jsmith

dn: cn=John Q. Public,ou=people,dc=icinga,dc=org cn: John Q. Public uid: jqpublic

dn: cn=Richard Roe,ou=people,dc=icinga,dc=org cn: Richard Roe uid: jroe

All users share the password password.
