How to Install OpenProject on Arch Linux

OpenProject is a flexible and open-source project management tool that can handle complex projects with multiple tasks and timelines. In this tutorial, we will walk you through the installation of OpenProject on Arch Linux.

Prerequisites

Before you begin, ensure that your Arch Linux system is up to date by running the following command:

sudo pacman -Syu

Step 1: Install the Required Dependencies

OpenProject requires a few dependencies to run correctly. Use the following command to install the required dependencies:

sudo pacman -S ruby postgresql yarn

Step 2: Install OpenProject

Next, you need to install OpenProject on your Arch Linux system. Follow these steps to do it:

Download and install the GPG key:

sudo pacman-key --recv-keys EA5BBD71E7AF9435
sudo pacman-key --lsign EA5BBD71E7AF9435

Add the OpenProject package repository to your Arch Linux system by creating a new file called openproject.repo in the /etc/pacman.conf.d/ directory:
```
sudo nano /etc/pacman.conf.d/openproject.repo
```
Add the following lines to the file:
```
[openproject]
SigLevel = Optional TrustAll
Server = https://dl.packager.io/srv/opf/openproject/stable/archlinux/$arch
```
Update the package list:
```
sudo pacman -Sy
```
Install OpenProject:
```
sudo pacman -S openproject
```

Step 3: Configure the Database

OpenProject requires a PostgreSQL database to store data. Follow these steps to configure the database:

Start the PostgreSQL service and enable it to start at boot:

sudo systemctl start postgresql
sudo systemctl enable postgresql

Create a new user and a new database for OpenProject:

sudo su - postgres
createuser -P openproject
createdb -O openproject openproject_production
exit

Import the database schema to the new database:

sudo -u openproject psql -d openproject_production -f /opt/openproject/config/database/postgresql.sql

Step 4: Configure OpenProject

Lastly, you need to configure OpenProject to use the newly created database. Follow these steps to do it:

Edit the database.yml file:

sudo nano /opt/openproject/config/database.yml

Replace the production section in the file with the following content:

production:
  adapter: postgresql
  database: openproject_production
  username: openproject
  password: [password]
  host: localhost
  port: 5432

Replace [password] with the password that you created for the openproject user in the previous step.

Save and close the file.
Run the following command to initialize OpenProject:
```
sudo openproject run bundle exec rake db:migrate
```

Start the OpenProject service and enable it to start at boot:

sudo systemctl start openproject
sudo systemctl enable openproject

Conclusion

You have successfully installed OpenProject on your Arch Linux system. You can now access the OpenProject web interface by browsing to http://localhost:8080 in your web browser.
