This document describes how to develop, build, package and install Apache CloudStack. For more information please refer to the official documentation or the developer wiki.
Apache CloudStack developers use various platforms for development, this guide was tested against a CentOS 7 x86_64 setup.
- Setting up development environment for Apache CloudStack.
- Building Apache CloudStack.
- Appliance based development
Install tools and dependencies used for development:
# yum -y install git java-17-openjdk java-17-openjdk-devel \
mysql mysql-server mkisofs git gcc python MySQL-python openssh-clients wget
Set up Maven (3.6.0):
# wget http://www.us.apache.org/dist/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz
# tar -zxvf apache-maven-3.6.3-bin.tar.gz -C /usr/local
# cd /usr/local
# ln -s apache-maven-3.6.3 maven
# echo export M2_HOME=/usr/local/maven >> ~/.bashrc # or .zshrc or .profile
# echo export PATH=/usr/local/maven/bin:${PATH} >> ~/.bashrc # or .zshrc or .profile
# source ~/.bashrc
Setup up NodeJS (LTS):
# curl -sL https://rpm.nodesource.com/setup_12.x | sudo bash -
# sudo yum install nodejs
# sudo npm install -g @vue/cli npm-check-updates
Start the MySQL service:
$ service mysqld start
CloudStack is built using Java and Python. To make selection of these tools versions more consistent and ease installation for developers, optional support for jenv and pyenv with [virtualenv]|(https://github.com/yyuu/pyenv-virtualenv) is provided. jenv installation instructions are available here and pyenv installation instructions are available here. For users of oh-my-zsh there is a pyenv plugin available to trigger configuration of pyenv in a shell session.
Following installation, execute the following commands to configure jenv and pyenv for use with CloudStack development:
# pyenv install 2.7.16 ## Install Python 2.7.16
# pyenv virtualenv 2.7.16 cloudstack ## Create a cloudstack virtualenv using Python 2.7.16
# pip install -r <root CloudStack source tree>/requirements.txt ## Install cloudstack Python dependencies
# jenv add <path to JDK 1.8 installation> ## Add Java7 to jenv
N.B. If you are running Linux, you may need to install additional packages to allow pyenv to build Python.
Following these steps, jenv and pyenv will use .java-version and .python-version files in the root of the CloudStack source tree to switch to the correct Java version and the cloudstack Python virtualenv for CloudStack development.
You may get the source code from the repository hosted on Apache:
$ git clone https://gitbox.apache.org/repos/asf/cloudstack.git
Or, you may fork the repository from the official Apache CloudStack mirror on GitHub
To checkout a specific branch, for example 4.11, do:
$ git fetch origin
$ git checkout -b 4.11 origin/4.11
Clean and build:
$ mvn clean install -P systemvm,developer
Clear old database (if any) and deploy the database schema:
$ mvn -P developer -pl developer -Ddeploydb
Export the following variable if you need to run and debug the management server:
$ export MAVEN_OPTS="-Xmx1024m -XX:MaxMetaspaceSize=500m -Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n"
Start the management server:
$ mvn -pl :cloud-client-ui jetty:run
If this works, you've successfully setup a single server Apache CloudStack installation.
Open the following URL on your browser to access the Management Server UI:
http://localhost:8080/client/
The default credentials are; user: admin, password: password and the domain field should be left blank which is defaulted to the ROOT domain.
CloudStack supports several plugins that depend on libraries with distribution restrictions. Because of this they are not included in the default build. Enable these additional plugins activate their respective profiles. For convenience adding -Dnoredist will enable all plugins that depend on libraries with distribution restrictions. The build procedure expects that the required libraries are present in the maven repository.
The following procedure can be used to add the libraries to the local maven repository. Details on obtaining the required libraries can be found in this file. Note that this will vary between releases of CloudStack
$ cd deps
$ ./install-non-oss.sh
To build all non redistributable components, add the noredist flag to the build command:
$ mvn clean install -P systemvm,developer -Dnoredist
Before packaging, please make sure you go through the "Building" section above. This section describes packaging and installation.
To create debs install the following extra packages:
# apt-get -y install python-mysqldb
# apt-get -y install debhelper
Then:
$ mvn -P deps # -D noredist, for noredist as described in the "Building" section above
$ dpkg-buildpackage -uc -us
All the deb packages will be located one level down.
To create rpms, install the following extra packages:
# yum -y install rpm-build
# yum -y install ws-commons-util
# yum -y install gcc
# yum -y install glibc-devel
# yum -y install MySQL-python
Then:
$ cd packaging
$ package.sh
To create packages for noredist add the -p noredist
option to the package script.
All the rpm packages will be created in dist/rpmbuild/RPMS/x86_64
directory.
If you will be using Xen as your hypervisor, please download vhd-util
If management server is installed on RHEL/CentOS, then copy vhd-util into:
/usr/lib64/cloud/common/scripts/vm/hypervisor/xenserver/
If management server is installed on Ubuntu, then put vhd-util into:
/usr/lib/cloud/common/scripts/vm/hypervisor/xenserver/vhd-util
