Open Port 80 Oracle Cloud Compute Instance (CentOS)
FYI This was harder than it needed to be:
Looking at your instance info, find VNIC section, click "Public Subnet".
Click on your security list.
Add a new entry with the following options:
"Stateless" = No, "Source" = 0.0.0.0/0, "IP Protocol" = TCP, "Source Port Range" = All, "Destination Port Range" = 80
SSH to your instance.
While SSH'ed in your instance, run command firewall-cmd --permanent --add-service=http.
While SSH'ed in your instance, run command firewall-cmd --reload.
Now start Apache, NGINX, or whatever server you need to on port 80. You can now access from the internet.

setup xong ra link và chạy 2 file dưới để ra config

sửa file env:
vi mailu.env
sửa TLS_FLAVOR=notls
sửa file docker chỉnh 2 port 443 và 80 sang port khác sau đó trỏ nginx vào http là được.

docker compose -p mailu up -d

tạo password 
docker compose -p mailu exec admin flask mailu admin admin uptool.org {PASSWORD}

config nginx 

Sau đó vào url check với tài khoản [e-mail]

Looking for a later version of NodeJS? Follow my tutorial on how to install NodeJS 16 on Ubuntu 20.04.

Step 1 - Add NodeSource PPA

Let's begin by installing the NodeSource PPA. This will allow us to install later versions of NodeJS using the Apt package manager. Let's ensure we're in the home directory and download the setup script:

cd ~
curl -sL https://deb.nodesource.com/setup_14.x -o setup_14.sh

Next, let's run the setup which will add the NodeSource PPA:

sudo sh ./setup_14.sh

Step 2 - Install NodeJS

We will now have the NodeSource PPA added, allowing us to install NodeJS 14. First let's update the APT package library:

sudo apt update

And finally, install NodeJS 14:

sudo apt install nodejs

Step 3 - Verify NodeJS version

We should now have NodeJS 14 installed. We will need to check the version installed, we can do this by running the following command:

node -v

You should see an output that shows NodeJS being at least 14.16:

// Some code
 sudo dnf module list --all nodejs
  454  sudo dnf module enable nodejs:14
  455  sudo dnf module reset nodejs:10
  456  sudo dnf module enable nodejs:14
  457  sudo dnf module install nodejs
