Merge pull request #1647 from apache/4.9-systemdubuntupkging
[lts] CLOUDSTACK-9462: Systemd support for Ubuntu 16.04Created this based on @wido 's origin PR #1541 . Requesting for review and testing -- @jburwell @karuturi @wido @vincentbernat @wido I think this change only brings systemd support to agent and usage packages, or does cloudstack-management pkg has systemd support too? @blueorangutan package - systemd: Add a /etc/sysconfig/cloudstack-* file This allows users to easily override variables passed to Java when starting up. It also creates a foundation for sharing the systemd service profile between CentOS and Ubuntu since it only requires the environment file to be changed. - deb: Add Ubuntu 16.04 support Ubuntu 16.04 differs from Ubuntu 14.04 in a few ways: - systemd instead of sysvinit / upstart - Java 8 support The packaging now detects on which distribution it is being build and based on that it installs different files in the packages, but it also changes the Dependencies. * pr/1647: CLOUDSTACK-9462: Refactor systemd scripts CLOUDSTACK-9462: Systemd support for Ubuntu 16.04 Signed-off-by: Rohit Yadav <rohit.yadav@shapeblue.com>

# CloudStack RPM and DEB packaging
2+
This directory contains all the required scripts and tools needed to build RPM and DEB packages for Apache CloudStack.
3+
4+
These scripts are also used by the CloudStack team to build packages for the official release of CloudStack.
5+
6+
# Requirements
7+
The RPM and DEB packages have dependencies on versions of specific libraries. Due to these dependencies the following distributions and their versions are supported by the packages.
8+
9+
* CentOS / RHEL: 6 and 7
10+
* Debian 7 (Wheezy) and 8 (Jessy) (untested!)
11+
* Ubuntu: 14.04 (Trusty) and 16.04 (Xenial)
12+
13+
# Building
14+
Using the scripts in the *packaging* directory the RPM and DEB packages can be build.
15+
16+
## DEB
17+
If you simply want to build packages go to the root directory of your CloudStack source code and run:
18+
19+
``dpkg-buildpackage``
20+
21+
This will build packages for the current distribution version you are running. If you run this on a Ubuntu 16.04 system the packages will be tailored for Ubuntu 16.04 and will not install on Ubuntu 14.04.
22+
23+
### Building cross-distribution
24+
If you want to build packages for a different distribution run the *build-deb.sh* script. This will build packages with the current distribution as a suffix to the package names. E.g. *cloudstack-agent_4.9.0~xenial_all.deb*
25+
26+
Using a Docker image you can build packages for a distribution you are not running.
27+
28+
The following commands assume that the CloudStack source is present in **/tmp/cloudstack** on the system you are running these commands on.
29+
30+
``docker run -ti -v /tmp:/src ubuntu:16.04 /bin/bash -c "apt-get update && apt-get install -y dpkg-dev python debhelper openjdk-8-jdk genisoimage python-mysql.connector maven lsb-release devscripts && /src/cloudstack/packaging/build-deb.sh"``
31+
32+
``docker run -ti -v /tmp:/src ubuntu:14.04 /bin/bash -c "apt-get update && apt-get install -y dpkg-dev python debhelper openjdk-7-jdk genisoimage python-mysql.connector maven lsb-release devscripts && /src/cloudstack/packaging/build-deb.sh"``
33+
34+
The commands above will generate Ubuntu 14.04 and 16.04 packages which you will find in */tmp* on your system after the build succeeds.
35+
36+
## RPM
37+
The *package.sh* script can be used to build RPM packages for CloudStack. In the *packaging* script you can run the following command:
38+
39+
``./package.sh --pack oss --distribution centos7``
