### <a id="package-repositories"></a> Setting up Package Repositories
|
||
|
||
You need to add the Icinga repository to your package management configuration for installing Icinga Web 2.
|
||
Below is a list with examples for various distributions.
|
||
|
||
Debian (debmon):
|
||
````
|
||
wget -O - http://debmon.org/debmon/repo.key 2>/dev/null | apt-key add -
|
||
echo 'deb http://debmon.org/debmon debmon-wheezy main' >/etc/apt/sources.list.d/debmon.list
|
||
apt-get update
|
||
````
|
||
|
||
Ubuntu Trusty:
|
||
````
|
||
wget -O - http://packages.icinga.org/icinga.key | apt-key add -
|
||
add-apt-repository 'deb http://packages.icinga.org/ubuntu icinga-trusty main'
|
||
apt-get update
|
||
````
|
||
|
||
For other Ubuntu versions just replace trusty with your distribution's code name.
|
||
|
||
RHEL and CentOS:
|
||
````
|
||
rpm --import http://packages.icinga.org/icinga.key
|
||
curl -o /etc/yum.repos.d/ICINGA-release.repo http://packages.icinga.org/epel/ICINGA-release.repo
|
||
yum makecache
|
||
````
|
||
|
||
Fedora:
|
||
````
|
||
rpm --import http://packages.icinga.org/icinga.key
|
||
curl -o /etc/yum.repos.d/ICINGA-release.repo http://packages.icinga.org/fedora/ICINGA-release.repo
|
||
yum makecache
|
||
````
|
||
|
||
SLES 11:
|
||

The packages for RHEL/CentOS depend on other packages which are distributed as part of the
|
||
[EPEL repository](http://fedoraproject.org/wiki/EPEL). Please make sure to enable this repository by following
|
||
[these instructions](http://fedoraproject.org/wiki/EPEL#How_can_I_use_these_extra_packages.3F).

||
|
||
### <a id="installing-from-package-example"></a> Installing Icinga Web 2
|
||
|
||
You can install Icinga Web 2 by using your distribution's package manager to install the `icingaweb2` package.
|
||
Below is a list with examples for various distributions.
|
||
|
||
Debian and Ubuntu:
|
||
````
|
||
apt-get install icingaweb2
|
||
````
|
||
|
||
RHEL, CentOS and Fedora:
|
||
````
|
||
yum install icingaweb2
|
||
````
|
||
|
||
SLES and openSUSE:
|
||
````
|
||
zypper install icingaweb2
|
||
````
|
||
|
||
### <a id="preparing-web-setup-from-package"></a> Preparing Web Setup
|
||
|
||
You can set up Icinga Web 2 quickly and easily with the Icinga Web 2 setup wizard which is available the first time
|
||
you visit Icinga Web 2 in your browser. When using the web setup you are required to authenticate using a token.
|
||
In order to generate a token use the `icingacli`:
|
||
````
|
||
icingacli setup token create
|
||
````
|
||
|
||
In case you do not remember the token you can show it using the `icingacli`:
|
||
````
|
||
icingacli setup token show
|
||
````
|
||
|
||
Finally visit Icinga Web 2 in your browser to access the setup wizard and complete the installation:
|
||
`/icingaweb2/setup`.
|
||
|
||
## <a id="installing-from-source"></a> Installing Icinga Web 2 from Source
|
||
|
||
Although the preferred way of installing Icinga Web 2 is to use packages, it is also possible to install Icinga Web 2
|
||
directly from source.
|
||
|
||
### <a id="getting-the-source"></a> Getting the Source
|
||
|
||
First of all, you need to download the sources. Icinga Web 2 is available through a Git repository. You can clone this
|
||
repository either via git or http protocol using the following URLs:
|
||
|
||
* git://git.icinga.org/icingaweb2.git
|
||
* http://git.icinga.org/icingaweb2.git
|
||
|
||
There is also a browsable version available at
|
||
[git.icinga.org](https://git.icinga.org/?p=icingaweb2.git;a=summary "Icinga Web 2 Git Repository").
|
||
This version also offers snapshots for easy download which you can use if you do not have git present on your system.
|
||
|
||
````
|
||
git clone git://git.icinga.org/icingaweb2.git
|
||
````
|
||
|
||
### <a id="installing-from-source-example"></a> Installing Icinga Web 2
|
||
|
||
Choose a target directory and move Icinga Web 2 there.
|
||
|
||
````
|
||
mv icingaweb2 /usr/share/icingaweb2
|
||
````
|
||
|
||
### <a id="configuring-web-server"></a> Configuring the Web Server
|
||
|
||
Use `icingacli` to generate web server configuration for either Apache or nginx.
|
||
|
||
Apache:
|
||
````
|
||
./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb2/public
|
||
````
|
||
|
||
nginx:
|
||
````
|
||
./bin/icingacli setup config webserver nginx --document-root /usr/share/icingaweb2/public
|
||
````
|
||
|
||
Save the output as new file in your webserver's configuration directory.
|
||
|
||
Example for Apache on RHEL or CentOS:
|
||
````
|
||
./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb2/public > /etc/httpd/conf.d/icingaweb2.conf
|
||
````
|
||
|
||
### <a id="preparing-web-setup-from-source"></a> Preparing Web Setup
|
||
|
||
You can set up Icinga Web 2 quickly and easily with the Icinga Web 2 setup wizard which is available the first time
|
||
you visit Icinga Web 2 in your browser. Please follow the steps listed below for preparing the web setup.
|
||
|
||
Because both web and CLI must have access to configuration and logs, permissions will be managed using a special
|
||
system group. The web server user and CLI user have to be added to this system group.
|
||
|
||
Add the system group `icingaweb2` in the first place.
|
||
|
||
Fedora, RHEL, CentOS, SLES and OpenSUSE:
|
||
````
|
||
groupadd -r icingaweb2
|
||
````
|
||
|
||
Debian and Ubuntu:
|
||
````
|
||
addgroup --system icingaweb2
|
||
````
|
||
|
||
Add your web server's user to the system group `icingaweb2`:
|
||
|
||
Fedora, RHEL and CentOS:
|
||
````
|
||
usermod -a -G icingaweb2 apache
|
||
````
|
||
|
||
SLES and OpenSUSE:
|
||
````
|
||
usermod -A icingaweb2 wwwrun
|
||
````
|
||
|
||
Debian and Ubuntu:
|
||
````
|
||
usermod -a -G icingaweb2 www-data
|
||
````
|
||
|
||
Use `icingacli` to create the configuration directory which defaults to **/etc/icingaweb2**:
|
||
````
|
||
./bin/icingacli setup config directory
|
||
````
|
||
|
||
|
||
When using the web setup you are required to authenticate using a token. In order to generate a token use the
|
||
`icingacli`:
|
||
````
|
||
./bin/icingacli setup token create
|
||
````
|
||
|
||
In case you do not remember the token you can show it using the `icingacli`:
|
||
````
|
||
./bin/icingacli setup token show
|
||
````
|
||
|
||
Finally visit Icinga Web 2 in your browser to access the setup wizard and complete the installation:
|
||
`/icingaweb2/setup`.
|
||
|
||
## <a id="upgrading-to-beta2"></a> Upgrading to Icinga Web 2 Beta 2
|
||
|
||
Icinga Web 2 Beta 2 introduces access control based on roles for secured actions. If you've already set up Icinga Web 2,
|
||
you are required to create the file **roles.ini** beneath Icinga Web 2's configuration directory with the following
|
||
content:
|
||
````
|
||
[administrators]
|
||
users = "your_user_name, another_user_name"
|
||
permissions = "*"
|
||
````
|
||
|
||
After please log out from Icinga Web 2 and log in again for having all permissions granted.
|
||
|
||
If you delegated authentication to your web server using the `autologin` backend, you have to switch to the `external`
|
||
authentication backend to be able to log in again. The new name better reflects what’s going on. A similar change
|
||
affects environments that opted for not storing preferences, your new backend is `none`.
|
||
|
||
## <a id="upgrading-to-beta3"></a> Upgrading to Icinga Web 2 Beta 3
|
||
|
||
Because Icinga Web 2 Beta 3 does not introduce any backward incompatible change you don't have to change your
|
||
configuration files after upgrading to Icinga Web 2 Beta 3.
