Ssh and vnc server [closed]

Question

I want to setup my pi 3 working with just a power bank and my phone via mobile Hotspot. I know that ssh and vnc server are two ways to do it but I don't know how.

Thanks for your time and I appreciate all the help i can get.

1. Network layer: decide whether to use your phone in tethering mode so it works as an access point, or configure the Pi to act as an access point. Unless you can connect both devices to an existing Wifi network, you'll need to put one device into access point (AP) mode.
   • phone as AP: connect your Pi to your phone AP using the usual Wifi procedure. You can do this from the Pixel desktop while your Pi is connected to an HDMI monitor, and ISB mouse and keyboard attached. Afterwards, it will remember this. Or you edit /etc/wpa_supplicant/wpa_supplicant.conf and add your phone's name (SSID) and key. See also https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md
   • Pi as AP: see https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md for details how to configure your Pi, then connect your phone to the Pi's AP, like you connect to any other Wifi network.
2. Services
   • on the Pi use sudo raspi-config to enable SSH and/or VNC. I recommend enabling both, unless you want to use SSH only.
   • on your phone, get an SSH client app and/or the official VNC client app. On Android, I recommend JuiceSSH from my own personal experience. For VNC, use the official VNC client to avoid all kind of protocol issues with different VNC clients and servers.

Enjoy. I'm using such a setup on a regular basis to maintain a set of Pi Zero Ws, and even sometimes 3Bs. For me, SSH mostly sufficies, but from time to time I may need a GUI session, which is when VNC comes in handy.
