[root@vps ~]# 

This command will list the available Node.js streams. Choose the appropriate stream, for example, nodejs:20, and install it:

yum module install nodejs:20

Verify the installation by checking the Node.js version:

node -v

Output:

[root@vps ~]# node -v
v20.11.0
[root@vps ~]#

Clone Puter Repository

Install Git if not already installed,

dnf install git -y

Now that Node.js is installed, let's proceed to clone the Puter repository from GitHub and navigate into the cloned directory,

git clone https://github.com/HeyPuter/puter

After installing dependencies, you can start the Puter application,

npm start

Output:

[root@vps puter]# npm start

> puter.com@1.0.0 start
> nodemon --exec "node dev-server.js"

[root@vps puter]#

Configure Firewall

---

Ensure that the required port (default: 4000) is open in your firewall to allow external access to the Puter application. Check the firewall status,

firewall-cmd --list-all

Output:

[root@vps puter]# firewall-cmd --list-all
public (active)
  target: default
  icmp-block-inversion: no
  interfaces: ens3
  sources: 
  services: cockpit dhcpv6-client ssh
  ports: 
  protocols: 
  forward: no
  masquerade: no
  forward-ports: 
  source-ports: 
  icmp-blocks: 
  rich rules: 
[root@vps puter]# 

If the port is not open, add it to the firewall rules,

firewall-cmd --zone=public --add-port=4000/tcp --permanent

Reload the firewall to apply changes,

firewall-cmd --reload

Output:

[root@vps puter]# firewall-cmd --reload
success
[root@vps puter]#
