# groupadd icingacmd
# useradd -c "icinga" -s /sbin/nologin -G icingacmd -g icinga icinga
+On Alpine (which uses ash busybox) you can run:
+
+ # addgroup -S icinga
+ # addgroup -S icingacmd
+ # adduser -S -D -H -h /var/spool/icinga2 -s /sbin/nologin -G icinga -g icinga icinga

Add the web server user to the icingacmd group in order to grant it write
permissions to the external command pipe and livestatus socket:
directory. Alternatively the `-DICINGA2_GIT_VERSION_INFO=OFF` option for CMake
can be used to disable the usage of `git describe`.

+## Build Icinga 2 RPMs
+
+### Build Environment on RHEL, CentOS, Fedora, Amazon Linux
+
+Setup your build environment:
+
+ yum -y install rpmdevtools
+
+### Build Environment on SuSE/SLES
+
+SLES:
+
+ zypper addrepo http://download.opensuse.org/repositories/devel:tools/SLE_12_SP2/devel:tools.repo
+ zypper refresh
+ zypper install rpmdevtools spectool
+
+OpenSuSE:

+ zypper refresh
+ zypper install rpmdevtools spectool
+
+### Package Builds
+
+Prepare the rpmbuild directory tree:
+
+ cd $HOME
+ rpmdev-setuptree
+
+Copy the icinga2.spec file to `rpmbuild/SPEC` or fetch the latest version:
+
+ curl https://raw.githubusercontent.com/Icinga/icinga2/master/icinga2.spec -o $HOME/rpmbuild/SPECS/icinga2.spec
+
+Copy the tarball to `rpmbuild/SOURCES` e.g. by using the `spectool` binary
+provided with `rpmdevtools`:
+
+ cd $HOME/rpmbuild/SOURCES
+ spectool -g ../SPECS/icinga2.spec
+
+ cd $HOME/rpmbuild
+
+Install the build dependencies. Example for CentOS 7:
-Setup your build environment on RHEL/SUSE and copy the generated tarball from your git
-repository to `rpmbuild/SOURCES`.
+ yum -y install libedit-devel ncurses-devel gcc-c++ libstdc++-devel openssl-devel \
+ cmake flex bison boost-devel systemd mysql-devel postgresql-devel httpd \
+ selinux-policy-devel checkpolicy selinux-policy selinux-policy-doc
-Copy the icinga2.spec file to `rpmbuild/SPEC` and then run this command:
+Note: If you are using Amazon Linux, systemd is not required.
- $ rpmbuild -ba SPEC/icinga2.spec
+A shorter way is available using the `yum-builddep` command on RHEL based systems:
+
+ yum-builddep SPECS/icinga2.spec
+
+Build the RPM:
+
+ rpmbuild -ba SPECS/icinga2.spec
+

- yum install -y devtoolset-2-gcc devtoolset-2-gcc-c++ devtoolset-2-binutils
+Dependencies to devtools-2 are used in the RPM SPEC, so the correct tools
+should be used for building.
+
+As an alternative, you can use newer Boost packages provided on
+[packages.icinga.com](https://packages.icinga.com/epel).

+If you prefer to build packages offline, a suitable Vagrant box is located

#### SLES 11
The Icinga repository provides the required boost package version and must be
added before building.
-### Building Icinga 2 Debs
+## Build Icinga 2 Debian/Ubuntu packages
Setup your build environment on Debian/Ubuntu, copy the 'debian' directory from
the Debian packaging Git repository (https://github.com/Icinga/pkg-icinga2-debian)
$ dpkg-buildpackage -uc -us
-### Building Post Install Tasks
+
+## Build Alpine Linux packages
+
+A simple way to setup a build environment is installing Alpine in a chroot.
+In this way, you can set up an Alpine build environment in a chroot under a
+different Linux distro.
+There is a script that simplifies these steps with just two commands, and
+can be found [here](https://github.com/alpinelinux/alpine-chroot-install).
+
+Once the build environment is installed, you can setup the system to build
+the packages by following [this document](https://wiki.alpinelinux.org/wiki/Creating_an_Alpine_package).
+
+## Build Post Install Tasks
After building Icinga 2 yourself, your package build system should at least run the following post
install requirements:
* enable the `checker`, `notification` and `mainlog` feature by default
* run 'icinga2 api setup' in order to enable the `api` feature and generate SSL certificates for the node

...
+### Init Script
+
Icinga 2 can be started as a daemon using the provided init script:
# /etc/init.d/icinga2
Usage: /etc/init.d/icinga2 {start|stop|restart|reload|checkconfig|status}
-Or if your distribution uses systemd:
+### Systemd
+
+If your distribution uses Systemd:
# systemctl {start|stop|reload|status|enable|disable} icinga2
+In case the distribution is running Systemd >227, you'll also
+need to package and install the `etc/initsystem/icinga2.service.limits.conf`
+file into `/etc/systemd/system/icinga2.service.d`.
+
+### openrc
+
+Or if your distribution uses openrc (like Alpine):
+
+ # rc-service icinga2
+ Usage: /etc/init.d/icinga2 {start|stop|restart|reload|checkconfig|status}
+
+Note: the openrc's init.d is not shipped by default.
+A working init.d with openrc can be found here: (https://git.alpinelinux.org/cgit/aports/plain/community/icinga2/icinga2.initd). If you have customized some path, edit the file and adjust it according with your setup.
+Those few steps can be followed:
+
+ # wget https://git.alpinelinux.org/cgit/aports/plain/community/icinga2/icinga2.initd
+ # mv icinga2.initd /etc/init.d/icinga2
+ # chmod +x /etc/init.d/icinga2
+
Icinga 2 reads a single configuration file which is used to specify all
configuration settings (global settings, hosts, services, etc.). The
configuration format is explained in detail in the [doc/](doc/) directory.
