How to setup YunoHost at Oracle free tier VM

yunohost-oracle-free-tier.md

0. Register for Oracle Cloud Free Tier
1. Create compute instance
   • change image to Canonical Ubuntu
   • confirm that a public IPv4 address is assigned
   • upload your public ssh key
   • leave everything blank in Boot volume
2. Enable Internet Access
   • Instances → Instance details → Subnet → Default Security List → Add Ingress Rules
   • HTTP: Stateless: Checked Source Type: CIDR Source CIDR: 0.0.0.0/0 IP Protocol: TCP Source port range: (leave-blank) Destination Port Range: 80 Description: Allow HTTP connections
   • HTTPs: Stateless: Checked Source Type: CIDR Source CIDR: 0.0.0.0/0 IP Protocol: TCP Source port range: (leave-blank) Destination Port Range: 443 Description: Allow HTTPs connections
3. Connect to your ubuntu machine via ssh: ssh ubuntu@<your public IPv4 address> and install firewall software
   • update apt list: sudo apt update
   • install firewalld: sudo apt install firewalld -y
   • enable HTTP connection through port 80: sudo firewall-cmd --add-service=http --permanent
   • enable HTTPS connections on port 443: sudo firewall-cmd --add-service=https --permanent
   • reload the firewall: sudo firewall-cmd --reload
   • you can check that port is opened via sudo python3 -m http.server 80 and opening your public IPv4 address in a browser
4. Install debian using this script:
   • curl -fLO https://raw.githubusercontent.com/bohanyang/debi/master/debi.sh
   • chmod a+rx debi.sh
   • sudo ./debi.sh --version 11 --authorized-keys-url https://github.com/<github username>.keys – make sure that your public key is uploaded to github
   • sudo shutdown -r now
5. You need to wait around 5-7 minutes now.
6. Update known host authorization: ssh-keygen -R <your public IPv4 address>
7. Connect to newly created debian via ssh: ssh debian@<your public IPv4 address>
   • install some packages: sudo apt update && sudo apt install htop curl unzip tmux -y
   • start tmux session: tmux new -s yuno
   • become root: sudo -i
8. Install YunoHost:
   • run install script: curl https://install.yunohost.org | bash
   • open your public IPv4 address in a browser and proceed with the initial configuration
9. Note: next time you should connect to this machine via ssh admin@<your public IPv4 address> and use password from previus step. You can copy your public key later.
10. Optional For complete setup of YunoHost you need to open a couple more ports (5222, 5269, 25, 587, 993) the same way from second step. More info

P.S. I am not sure that third step is necessary.
