Ubuntu搭建SFTP文件服务服务器

Sure, I can help you with that! Here's a step-by-step guide to setting up an Nginx file server on Ubuntu 20.04: Step 1: Update System Packages Start by updating your system's package list by running the following command: ``` sudo apt update ``` Step 2: Install Nginx Next, install Nginx by running the following command: ``` sudo apt install nginx ``` Step 3: Configure Firewall If you have a firewall enabled (e.g., UFW), you'll need to allow HTTP traffic. Run the following command to allow it: ``` sudo ufw allow 'Nginx HTTP' ``` Step 4: Configure Nginx By default, Nginx is configured to serve files from the `/var/www/html` directory. You can edit the default configuration file using a text editor: ``` sudo nano /etc/nginx/sites-available/default ``` Inside this file, you can modify the `root` directive to specify the directory where you want to store your files. For example, if you want to use `/home/username/files` as your file directory, update the `root` directive as follows: ``` root /home/username/files; ``` Save the changes and exit the text editor. Step 5: Create File Directory Create the directory you specified in the Nginx configuration: ``` mkdir -p /home/username/files ``` Step 6: Adjust File Permissions To ensure that Nginx can access and serve the files, give the appropriate permissions to the directory: ``` sudo chown -R www-data:www-data /home/username/files ``` Step 7: Restart Nginx After making these changes, restart the Nginx service for the new configuration to take effect: ``` sudo systemctl restart nginx ``` Step 8: Upload Files Now, you can upload your files to the specified directory (`/home/username/files` in this example) using various methods like SCP, SFTP, or any other method you prefer. Step 9: Access Your Files You can access your files by navigating to your server's IP address or domain name in a web browser. For example, `http://your_server_ip` or `http://your_domain`. That's it! You have successfully set up an Nginx file server on Ubuntu 20.04.
