Installation into Conda environment#
This installation route installs all necessary software – including the prerequisite services PostgreSQL and RabbitMQ – into a Conda environment. This is the recommended method for users on shared systems and systems where the user has no administrative privileges. If you want to install AiiDA onto you own personal workstation/laptop, it is recommanded to use the system-wide installation.
This installation method installs all software into a conda environment, including PostgreSQL and RabbitMQ. See the system-wide installation to use Conda only to install the AiiDA (core) Python package.
Install all required services and the aiida-core package in a Conda environment.
Make sure that conda is installed, e.g., by following the instructions on installing Miniconda.
Open a terminal and execute:
$ conda create -n aiida -c conda-forge aiida-core aiida-core.services $ conda activate aiida
Before working with AiiDA, you must first initialize a database storage area on disk.
(aiida) $ initdb -D mylocal_db
This database cluster (located inside a folder named
mylocal_db) may contain a collection of databases (one per profile) that is managed by a single running server process.
We start this process with:
(aiida) $ pg_ctl -D mylocal_db -l logfile start
Then, start the RabbitMQ server:
(aiida) $ rabbitmq-server -detached
The services started this way will use the default ports on the machine. Conflicts may happen if there are more than one user running AiiDA this way on the same machine, or you already have the server running in a system-wide installation. To get around this issue, you can explicitly define the ports to be used.
Next, set up an AiiDA configuration profile and related data storage, with the
verdi quicksetup command.
(aiida) $ verdi quicksetup Info: enter "?" for help Info: enter "!" to ignore the default and set no value Profile name: me Email Address (for sharing data): firstname.lastname@example.org First name: my Last name: name Institution: where-i-work
In case of non-default ports are used for the database cluster and the RabbitMQ server, you can pass them using
--broker-port options respectively.
Once the profile is up and running, you can start the AiiDA daemon(s):
(aiida) $ verdi daemon start 2
The verdi daemon(s) must be restarted after a system reboot.
Do not start more daemons then there are physical processors on your system.
To check that everything is set up correctly, execute:
(aiida) $ verdi status ✓ version: AiiDA v2.0.0 ✓ config: /path/to/.aiida ✓ profile: default ✓ storage: Storage for 'default' @ postgresql://username:***@localhost:5432/db_name / file:///path/to/repository ✓ rabbitmq: Connected as amqp://127.0.0.1?heartbeat=600 ✓ daemon: Daemon is running as PID 2809 since 2019-03-15 16:27:52
After finishing with your aiida session, particularly if switching between profiles, you may wish to power down the daemon and the services:
(aiida) $ verdi daemon stop (aiida) $ pg_ctl -D mylocal_db stop (aiida) $ rabbitmqctl stop
If you want to restart the services and the daemon:
(aiida) $ pg_ctl -D mylocal_db start (aiida) $ rabbitmq-server -detached (aiida) $ verdi daemon start
If different ports are used, you have to pass them here as well.
