Check if the hostname is set:

Run the following command in SSH to display the current hostname:

hostname

It should match your website’s domain name.

If it’s not set correctly, add or update it like this:

1. Edit the /etc/hostname file:

sudo vim /etc/hostname

Add your desired hostname (e.g. your.domain.com) on a single line.

1. Edit the /etc/hosts file:

sudo vim /etc/hosts

Make sure it includes:

127.0.0.1   localhost
127.0.1.1   your.domain.com

1. Apply the changes:

sudo hostname your.domain.com

And either restart the systemd-hostnamed service or reboot the server:

sudo systemctl restart systemd-hostnamed

or

sudo reboot

Setup una permissions:

#!/bin/bash
# Move into the 'una' directory
cd una

# Change the owner of all files and folders to 'www-data' (the default web server user)
sudo chown -R www-data:www-data .

# Set permissions for all directories to 755:
# 7 = read (4) + write (2) + execute (1) for the owner
# 5 = read (4) + execute (1) for the group
# 5 = read (4) + execute (1) for others
sudo find ./ -type d -exec chmod 755 {} \;

# Set permissions for all files to 644:
# 6 = read (4) + write (2) for the owner
# 4 = read (4) for the group
# 4 = read (4) for others
sudo find ./ -type f -exec chmod 644 {} \;

# Give execute permission to ffmpeg.exe (because it’s an executable file)
sudo chmod +x ./plugins/ffmpeg/ffmpeg.exe

# Show confirmation message
echo "Permissions successfully set."

Check the latest 50 log entries in your app logs:

cd una
tail -n 50 ./logs/*.log

And for NGINX logs:

tail -n 50 /var/log/nginx/access.log
tail -n 50 /var/log/nginx/error.log

List cronjobs:

sudo crontab -u www-data -l 

To edit cron jobs for the www-data user, run:

sudo crontab -u www-data -e
