Evergreen is an open-source integrated library system software that helps manage library resources such as books, audio, and video media. In this tutorial, we will discuss the steps to install Evergreen on OpenBSD.
Before we begin, you need to have the following prerequisites installed on your OpenBSD system:
First, we need to install some dependencies required to run Evergreen on OpenBSD. Open a terminal window and run the following command:
# pkg_add -v postgresql postgresql-server apache-httpd ap2-mod_wsgi3 py3-virtualenv
This command will download and install PostgreSQL, Apache2, Wsgi, and Python Virtualenv on your OpenBSD system.
After successfully installing the PostgreSQL server, you need to initialize and start it. Run the following command to initialize the database cluster:
# su - _postgresql
$ initdb -D /var/postgresql/data
Next, edit the pg_hba.conf
file to allow the Evergreen user to connect to the PostgreSQL server. Open the file in your preferred text editor and add the following line:
host evergreen evergreen 127.0.0.1/32 md5
Now, start the PostgreSQL server by running the following command:
$ rcctl start postgresql
Create a virtual environment for Evergreen using the Python Virtualenv tool. Run the following command to create a virtual environment named evergreen
:
# virtualenv -p python3 /usr/local/lib/evergreen
Next, activate the virtual environment by running:
# source /usr/local/lib/evergreen/bin/activate
You should now see evergreen
in the command prompt which indicates that the virtual environment is active.
Next, we need to install Evergreen in the virtual environment. You can install the latest version of Evergreen by running the following command:
# pip install -U evergreen
After installing, you need to configure Evergreen. Create a file called evergreen.conf
in the /etc/evergreen
directory using the following command:
# mkdir /etc/evergreen; touch /etc/evergreen/evergreen.conf
Add the following configuration to the evergreen.conf
file:
[global]
server.environment = production
server.secret_key = generate-a-random-secret-key
[postgres]
dbname = evergreen
user = evergreen
password = evergreen
host = 127.0.0.1
port = 5432
[web]
listen.addr = 127.0.0.1
listen.port = 8080
Replace generate-a-random-secret-key
with a randomly generated secret key or a strong password.
Evergreen uses Apache as its web server. We need to configure Apache to work with Evergreen. Open the file /etc/httpd.conf
in your preferred text editor and add the following lines:
LoadModule wsgi_module /usr/local/libexec/apache24/mod_wsgi3.so
<VirtualHost *:80>
ServerName localhost
ServerAdmin webmaster@localhost
WSGIDaemonProcess evergreen display-name=%{GROUP} process-group=evergreen
WSGIProcessGroup evergreen
WSGIScriptAlias / /usr/local/lib/evergreen/evergreen.wsgi
<Directory /usr/local/lib/evergreen>
AllowOverride None
Require all granted
</Directory>
ErrorLog /var/log/httpd-error.log
CustomLog /var/log/httpd-access.log combined
</VirtualHost>
Next, restart the Apache server by running the following command:
# rcctl restart httpd
It is time to run Evergreen. Activate the virtual environment using the following command:
# source /usr/local/lib/evergreen/bin/activate
Next, run the following command to start the Evergreen server:
# evergreen-server
You should see a message similar to the following:
* Serving Flask app "evergreen:app" (lazy loading)
* Environment: production
WARNING: Do not use the development server in a production environment.
Use a production WSGI server instead.
* Debug mode: off
* Running on http://127.0.0.1:8080/ (Press CTRL+C to quit)
Now, open your web browser and go to http://localhost. You should see the Evergreen login page. Use the default username admin
and password admin
to log in and begin using Evergreen.
Congratulations! You have successfully installed Evergreen on OpenBSD.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
