NGINX [Http Server]

用nginx 來架設HTTP server

• OS: ubuntu 20.04

Ubuntu 安裝 NGINX

1. NGINX 基本設定

Step 1. 安裝 Nginx

sudo apt install nginx -y

Step 2. 檢查狀態

sudo systemctl status nginx

Step 3. 防火牆設定

sudo ufw allow 'Nginx HTTP'
sudo ufw reload

Step 4.測試看看，開啟瀏覽器

http://172.21.201.250
or 
http://127.0.0.1

Http 網頁改成檔案總管

• 權限設定

  sudo chmod 644 /var/www/html/
  

• ngnix 設定 加 autoindex on

  sudo nano /etc/nginx/sites-available/default

    location / {
        try_files $uri $uri/ =404;
        autoindex on; # <--- Add this line
    }

• 測試config 有沒有問題 sudo nginx -t
• reload and apply

  sudo systemctl reload nginx
  

• 把.html網頁檔改掉其他檔名

sudo mv /var/www/html/index.nginx-debian.html /var/www/html/index.nginx-debian.html.bak

• 開啟瀏覽器
  

Docker 架 NGINX

安裝 Docker

• 安裝和設定 docker

  sudo apt update
  sudo apt install docker.io -y
  sudo systemctl start docker
  sudo systemctl enable docker
  sudo usermod -aG docker chenchih # Add your user to the docker group
  # Remember to log out and log back in (or reboot) for the group change to take effect
  

• 測試docker 沒問題

  docker run hello-world
  

• 拉下ngnix image

  #Pull or Run Nginx in Docker
  docker pull nginx:latest
  

• 跑 ngnix container

  docker run --name my-nginx -p 8080:80 -d nginx:latest
  

  Option設定:

  • --name my-nginx: Gives your container a memorable name.
  • -p 8080:80: Port mapping. Your Pi’s 8080 will point to the container’s 80.
  • -d: Detached mode (runs in the background).
  • nginx:latest: The image to use.

檢查Docker progress

• docker有沒有跑

  docker ps -a # Lists all containers, including  stopped items
  

  

• 檢查Docker images 在本地

  docker images
  

• 開啟瀏覽器
  開啟 http://<your_pi_ip_address>:8080 就可以看到如下:
  

移除 Container

• 停止和移除

  docker stop my-nginx # Stops the running container
  docker rm my-nginx # Removes the container instance
  

  可以再用docker ps -a 檢查
  

• 移除image 在本地

  docker rmi nginx:latest
