Server configuration

Steps below are the recommended server configuration.

Prepare environment

Create user to run diun (ex. diun)

groupadd diun
useradd -s /bin/false -d /bin/null -g diun diun

Create required directory structure

mkdir -p /var/lib/diun
chown diun:diun /var/lib/diun/
chmod -R 750 /var/lib/diun/
mkdir /etc/diun
chown diun:diun /etc/diun
chmod 770 /etc/diun

Configuration

You must create your first configuration file in /etc/diun/diun.yml and type:

chown diun:diun /etc/diun/diun.yml
chmod 644 /etc/diun/diun.yml

Copy binary to global location

cp diun /usr/local/bin/diun

Running Diun

After the above steps, two options to run Diun:

1. Creating a service file (recommended)

See how to create Linux service to start Diun automatically.

2. Running from command-line/terminal

DIUN_DB=/var/lib/diun/diun.db /usr/local/bin/diun --config /etc/diun/diun.yml

Updating to a new version

You can update to a new version of Diun by stopping it, replacing the binary at /usr/local/bin/diun and restarting the instance.

If you have carried out the installation steps as described above, the binary should have the generic name diun. Do not change this, i.e. to include the version number.
