Install a webserver on Linux in 15 minutes

Let's install a containerized web server stack on Linux! That will also deploy an intrusion prevention system with fail2ban, obtain trusted https certificates and a database server to install a WordPress blog.

We will use the free and open-source software Nginx.

Prerequisites

  • Linux Server running Ubuntu 20.04 LTS or newer
  • Domain that points to the public IP of your Linux Server

For installing Docker on other Linux distriubtions or different versions than Ubuntu 20.04 LTS, follow the official installation instructions.

Install Docker, and Docker-Compose

You can still install Docker on a Linux Server that is not running Ubuntu, however, this may require different commands!

Install Docker

sudo apt update

sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

sudo apt update

sudo apt-get install docker-ce docker-ce-cli containerd.io

Check if Docker is installed correctly

sudo docker run hello-world

Install Docker-Compose

Download the latest version (in this case it is 1.25.5, this may change whenever you read this tutorial!)

sudo curl -L "https://github.com/docker/compose/releases/download/1.25.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

Check if Docker-Compose is installed correctly

sudo docker-compose --version

(Optional) Add your linux user to the docker group

sudo usermod -aG docker $USER

Set up an Nginx Webserver

Create a new file docker-compose.ymlfile, please refer to the linuxserver/swag documentation: https://hub.docker.com/r/linuxserver/swag.

Example Docker-Compose File:

version: "2"
services:

  swag:
    image: linuxserver/swag
    container_name: swag
    cap_add:
      - NET_ADMIN
    environment:
      - PUID=1001
      - PGID=1001
      - TZ=Europe/Berlin
      - URL=do-test-1.the-digital-life.com
      - SUBDOMAINS=www
      - VALIDATION=http
    volumes:
      - /opt/webserver_swag/config:/config
    ports:
      - 443:443
      - 80:80 #optional
    restart: unless-stopped

To start your webserver just execute the following command, while you're in the /opt/webserver_swag folder.

docker-compose up -d

Add a database to the webserver

Update the Docker-Compose file

You can update your existing Docker-Compose template, if you want to add a database to your webserver. Because you often need a MySQL database, for example to deploy a WordPress Blog.

Example Docker-Compose File:

version: "2"
services:

  mariadb:
    image: linuxserver/mariadb
    container_name: mariadb
    environment:
      - PUID=1001
      - PGID=1001
      - MYSQL_ROOT_PASSWORD=mariadbpassword
      - TZ=Europe/Berlin
      - MYSQL_DATABASE=WP_database
      - MYSQL_USER=WP_dbuser
      - MYSQL_PASSWORD=WP_dbpassword
    volumes:
      - /opt/webserver_swag/config/mariadb:/config
    restart: unless-stopped

  swag:
    image: linuxserver/swag
    container_name: swag
    cap_add:
      - NET_ADMIN
    environment:
      - PUID=1001
      - PGID=1001
      - TZ=Europe/Berlin
      - URL=do-test-1.the-digital-life.com
      - SUBDOMAINS=
      - VALIDATION=http
    volumes:
      - /opt/webserver_swag/config:/config
    ports:
      - 443:443
      - 80:80 #optional
    depends_on:
      - mariadb
    restart: unless-stopped
