## Vagrant

	
> **Note** that the deployment of the virtual machine is tested against Vagrant starting with version 1.1.
> Unfortunately older versions will not work.

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](http://localhost:8080/icinga2-web).

### Environment

        <td>22</td>
    </tr>

        <td>HTTP</td>
        <td>8080</td>
        <td>80</td>
    </tr>
</table>

**Installed files**:

* `/usr/share/icinga/htpasswd.users` account information for logging into the Icinga classic web interface for both icinga instances
* `/usr/lib64/nagios/plugins` Nagios Plugins for both icinga instances

#### 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](http://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](http://localhost:8080/icinga-pgsql).
For **logging into** the Icinga classic web interface use user *icingaadmin* with password *icinga*.

#### Monitoring Test Config

Test config is added to both the MySQL and PostgreSQL Icinga instance utilizing the Perl module
**Monitoring::Generator::TestConfig** to generate test config to **/usr/local/share/misc/monitoring_test_config**
which is then copied to **<instance>/etc/conf.d/test_config/**.
Configuration can be adjusted and recreated with **/usr/local/share/misc/monitoring_test_config/recreate.pl**.
**Note** that you have to run

    vagrant provision

in the host after any modification to the script just mentioned. 

#### 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: cn=Jon Doe,ou=people,dc=icinga,dc=org
> uniqueMember: cn=Jane Smith,ou=people,dc=icinga,dc=org
> uniqueMember: cn=John Q. Public,ou=people,dc=icinga,dc=org
> uniqueMember: cn=Richard Roe,ou=people,dc=icinga,dc=org
> 
> 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: rroe

All users share the password `password`.

#### Testing the code

All software required to run tests is installed in the virtual machine. 
In order to run all tests you have to execute the following commands:
 
    vagrant ssh -c /vagrant/test/php/runtests
    vagrant ssh -c /vagrant/test/php/checkswag
    vagrant ssh -c /vagrant/test/js/runtests
    vagrant ssh -c /vagrant/test/js/checkswag
    vagrant ssh -c /vagrant/test/frontend/runtests

`runtests` will execute unit and regression tests and `checkswag` will report
code style issues.

#### Icinga 2

**Installation path**: `/usr/local/icinga2`

**Example usage**:

    cd /usr/local/icinga2
    ./sbin/icinga2 -c etc/icinga2/icinga2.conf.dist
