Build on Ubuntu Server 16.04
We strongly recommend using a newer supported version of Ubuntu LTS such as 18.04 or 20.04, as 16.04 has reached the Extended Security Maintenance phase of the support lifecycle.
Download Ubuntu Server LTS and install it on a system with at least 4GB of memory allocated. The instructions below are appropriate for Ubuntu 16.04 LTS. If you’re not using 16.04, please refer to the appropriate build instructions for your Ubuntu version.
If you just want to run a Haplo server with a minimum of fuss, go straight to the Production server documentation.
Important: Do not include a dot in the hostname. A good hostname to choose would be
If you’re using a VM, you’ll probably want to install openssh to allow you to log in from the VM host.
sudo apt-get install openssh-server
Install required packages
After logging in, install packages with:
sudo apt-get install software-properties-common sudo apt-get update sudo apt-get install g++ make openjdk-8-jdk-headless maven avahi-daemon uuid-dev curl patch git libxapian22v5 libxapian-dev
Check the version of java with
java -version. You must use Java 8, as older and newer versions aren’t compatible. If it’s not using Java 8, run
sudo update-alternatives --config java to set the correct version.
Install PostgreSQL 9.5 with:
sudo apt-get install postgresql-9.5 postgresql-server-dev-9.5 postgresql-contrib-9.5
This will initialise and run the PostgreSQL server. However, when testing and developing Haplo, you need to run PostgreSQL as the same user as the Haplo process. (In deployment, PostgreSQL runs under a different user.)
Disable the PostgreSQL daemon and allow the current user to run the server with:
sudo /etc/init.d/postgresql stop sudo update-rc.d postgresql disable
Setting up PostgreSQL
Create a database as the current user:
mkdir -p ~/haplo-dev-support/pg /usr/lib/postgresql/9.5/bin/initdb -E UTF8 -D ~/haplo-dev-support/pg
Running PostgreSQL for development and testing
Whenever you want to run the database, firstly, recreate the
/var/run/postgresql directory, as
/var/run gets wiped on every boot.
sudo mkdir -p /var/run/postgresql sudo chmod a+rwx /var/run/postgresql
Then, leave the following command running in a terminal window:
/usr/lib/postgresql/9.5/bin/postmaster -D ~/haplo-dev-support/pg
Open another terminal window now, before moving on to building Haplo.
Check out the repository from GitHub, for example, with:
cd ~ git clone https://github.com/haplo-org/haplo.git
Within the repository checkout, run the
fetch-and-compile.sh script. This will download about 110MB of archives, and create a
haplo-dev-support directory in your home directory.
cd ~/haplo ./fetch-and-compile.sh
Running the test suite
After ensuring PostgreSQL is running under the current user (see instructions above), run the test suite with:
If you see something like
'ERROR: could not access file ".../xapian_pg/oxp": Permission denied' then you are not running postgres as the same user as the test process.
If more than one or two tests fail, your system doesn’t have enough memory.
Running the application in development mode
After ensuring PostgreSQL is running under the current user (see instructions above), initialise the database with:
You only need to do this once.
To run the Haplo server:
Haplo runs as a multi-tenant application server, so before we can log into the server, we need to create an application.
In another terminal window:
cd ~/haplo db/init_app.sh haplo test.`hostname`.local "Test application" sme 4000 db/create_app_user.sh test.`hostname`.local "Ben Summers" email@example.com password echo Visit http://test.`hostname`.local:8080 in your browser.
The Haplo server will use multicast DNS to broadcast the hostname for the application, so a web browser on the machine on which the VM is running should be able to connect to the server on the address printed by the
You need to make sure your host OS can resolve multicast DNS:
Mac OS X: Supports multicast DNS out of the box.
Linux: Ensure the
avahi-daemon package is installed on the host OS.
Windows: There isn’t a good multicast DNS implementation for Windows. Find the IP address of the VM by running
ipconfig -a in the VM, then add the application hostnames to the
C:\Windows\System32\Drivers\etc\hosts file on the Windows host.
The development configuration uses a self-signed SSL certificate, so you’ll get a warning in your browser about the certificate.
Log into the application using the email address and password given on the third line above.
Click your user name in the top right, and choose “System management” to configure your application.
You may wish to try developing plugins with your development server.
