this repo is a more completed version to fourgames docs and apis : https://github.com/h0cean/fourgames
( this guide is mainly for ubuntu v18+ )
is to remove all typos and add missed steps of https://github.com/h0cean/fourgames to run this project
A. a domain with SSL/TLS
B. linux-based-host with sudo access
C. nginx
D.node.js
A. buy a domain and point it to your host's ip by using Cloudflare DNS service (you can use your preferred ones). ssh into host and make your host's traffic secure by configuring ufw, firewalld, IPTABLES...etc. here i use iptables: the result would be only port 22, 80 and 443 are accepting traffic
be carefull if your host's ssh-port is not 22, change the commands below for this specific port to the one you already use:
execute:
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -p icmp -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT
iptables -A INPUT -p tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j ACCEPT
iptables -P INPUT DROP
ip6tables -A INPUT -i lo -j ACCEPT
ip6tables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
ip6tables -A INPUT -p ipv6-icmp -j ACCEPT
ip6tables -P INPUT DROP
make them persistant:
apt install iptables-persistent
execute
$ sudo apt update
$ sudo apt install nginx
//copied from nginx official website for Ubuntu:
The available NGINX Ubuntu release support is listed at this distribution page. For a mapping of Ubuntu versions to release names, please visit the Official Ubuntu Releases page.
Append the appropriate stanza to /etc/apt/sources.list. If there is concern about persistence of repository additions (i.e. DigitalOcean Droplets), the appropriate stanza may instead be added to a different list file under /etc/apt/sources.list.d/, such as /etc/apt/sources.list.d/nginx.list:
deb https://nginx.org/packages/ubuntu/ $release nginx
deb-src https://nginx.org/packages/ubuntu/ $release nginx
e.g. Ubuntu 20.04 (Focal Fossa):
deb https://nginx.org/packages/ubuntu/ focal nginx
deb-src https://nginx.org/packages/ubuntu/ focal nginx
$ sudo apt update
$ sudo apt install nginx
//If a W: GPG error: https://nginx.org/packages/ubuntu focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY $key is encountered during the NGINX repository update, execute the following:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys $key
$ sudo apt update
$ sudo apt install nginx
You have now nginx installed on your server but not ready to serve web pages. you have to start the nginx. You can do this by using this command:
$ sudo systemctl start nginx
$ cd /tmp/
$ git clone https://github.com/Neilpang/acme.sh.git
Login as Root User ( sudo-i ) and execute:
$ touch /root/.bashrc
$ cd /tmp/acme.sh/
$ acme.sh --install --accountemail your-email-id@domain-here
$ acme.sh --set-default-ca --server letsencrypt
excute:
export CF_Token="Your_Cloudflare_DNS_API_Key"
execute
acme.sh --issue --dns dns_cf --ocsp-must-staple --keylength ec-384 -d domain-name.abc -d '*.domain-name.abc'
Your Cloudflare DNS API key is sotred in /root/.acme.sh/
make directory for certs:
mkdir command -pv /etc/nginx/ssl/domain-name.abc/
Next, change the dir and install diffie-hellman key-exchange-file
cd /etc/nginx/ssl/domain-name.abc/
openssl dhparam -out /etc/nginx/ssl/damain-name/dhparams.pem -dsaparam 4096
replace DOMAIN and execute:
acme.sh -d "$DOMAIN" --ecc --install-cert --fullchain-file "/etc/nginx/ssl/$DOMAIN/$DOMAIN.fullchain.cer.ecc" --key-file "/etc/nginx/ssl/$DOMAIN/$DOMAIN.key.ecc" --cert-file "/etc/nginx/ssl/$DOMAIN/$DOMAIN.cer.ecc"

There are quite a few ways to get up and running with Node.js on your Ubuntu 22.04 server. Your circumstances will dictate which of the above methods is best for your needs. While using the packaged version in Ubuntu’s repository is the easiest method, using nvm or a NodeSource PPA offers additional flexibility.
The version of Node.js included with Ubuntu 22.04, version 12.22.9, is an LTS, or “long-term support” release. It is technically outdated, but should be supported until the release of Ubuntu 24.04. ... so... its better to NOT use the easy way(packaged version in Ubuntu’s repository)
that is particularly flexible is to use nvm, the Node Version Manager. This piece of software allows you to install and maintain many different independent versions of Node.js, and their associated Node packages, at the same time
To install NVM on your Ubuntu 22.04 machine, visit the project’s GitHub page. Copy the curl command from the README file that displays on the main page. This will get you the most recent version of the installation script.
Before piping the command through to bash, it is always a good idea to audit the script to make sure it isn’t doing anything you don’t agree with. You can do that by removing the | bash segment at the end of the curl command:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh
Take a look and make sure you are comfortable with the changes it is making. When you are satisfied, run the command again with | bash appended at the end. The URL you use will change depending on the latest version of nvm, but as of right now, the script can be downloaded and executed by typing:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash
This will install the nvm script to your user account. To use it, you must first source your .bashrc file:
source ~/.bashrc
Now, you can ask NVM which versions of Node are available:
nvm list-remote
You can install a version of Node by typing any of the release versions you see. For instance, to get version v16.14.0 (another LTS release), you can type:
nvm install v16.14.0
You can see the different versions you have installed by typing:
nvm list
This shows the currently active version on the first line (-> v16.14.0), followed by some named aliases and the versions that those aliases point to.
you can also node -v to see node version installed
if you also have a version of Node.js installed through apt, you may see a system entry here. You can always activate the system-installed version of Node using nvm use system.
From a terminal, install gnupg and curl if they are not already available:
sudo apt-get install gnupg curl
To import the MongoDB public GPG key from
https://pgp.mongodb.com/server-7.0.asc
, run the following command:
curl -fsSL https://pgp.mongodb.com/server-7.0.asc | \ sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg \ --dearmor
for ubuntu 22.04 ,Create the list file /etc/apt/sources.list.d/mongodb-org-7.0.list for your version of Ubuntu.
echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list
