# startup with default settings on 7843 port
p3x-redis 

# if you want to disable changing of connections
p3x-redis --readonly-connections
# or
p3x-redis -r
# or
p3x-redis --config /home/p3x-redis-ui/p3xrs.json
# mix
p3x-redis --config /home/p3x-redis-ui/p3xrs.json --readonly-connections

Create a Linux SystemD service

adduser --disabled-password p3x-redis-ui
touch /etc/systemd/system/p3x-redis-ui.service
nano /etc/systemd/system/p3x-redis-ui.service

Place this file with this content:

[Unit]
Description=p3x-redis
After=network.target

[Service]
Type=simple
User=p3x-redis-ui
WorkingDirectory=/home/p3x-redis-ui
# or if you want readonly connections as it is public
#ExecStart=/usr/bin/p3x-redis --readonly-connections
#ExecStart=/usr/bin/p3x-redis --readonly-connections --config /home/p3x-redis-ui/p3xrs.json
ExecStart=/usr/bin/p3x-redis
Restart=on-abort

[Install]
WantedBy=multi-user.target

Finally:

systemctl daemon-reload
systemctl enable p3x-redis-ui
service p3x-redis-ui start

The server is loading at:
http://localhost:7843

The best is, if you have an NGINX with a valid, secure HTTPS certificate for example Let's Encrypt and then use it as a proxy, for example my own:

/etc/nginx/sites-enabled/p3x.redis.patrikx3.com

For free SSL certificate, I use acme.sh:
https://github.com/Neilpang/acme.sh
