To enable OpenWrt to automatically restore a previous backup during the first reboot after flashing, you can integrate the backup file and the restore script into the firmware during the build process. Here’s how to do it: 1. Create the files Directory In the root directory of your OpenWrt source tree, create a directory named files. Any files placed in this directory will be directly copied into the final firmware with the same directory structure. mkdir -p ~/openwrt/files 2. Add the Backup File and Script 2.1 Place the Backup File Copy the backup file you’ve prepared (e.g., backup.tar.gz) into the files/etc/backup/ directory: mkdir -p ~/openwrt/files/etc/backup cp /path/to/your/backup.tar.gz ~/openwrt/files/etc/backup/ Replace /path/to/your/backup.tar.gz with the actual path to your backup file. 2.2 Add the Auto-Restore Script Create an auto-restore script and place it in the files/etc/init.d/ directory, for example, named restore_backup: mkdir -p ~/openwrt/files/etc/init.d nano ~/openwrt/files/etc/init.d/restore_backup In the editor, add the following script content: #!/bin/sh # Define the backup file path BACKUP_FILE="/etc/backup/backup.tar.gz" # Check if the backup file exists if [ -f "$BACKUP_FILE" ]; then # Restore the…

the Nginx configuration and explanation for allowing external access only to the /report directory on an internal server, while blocking access to other directories: Configuration Example server { listen 80; server_name your-domain.com; # Allow access only to the /report directory location /report { proxy_pass http://192.168.1.1; # Replace with the actual internal server address proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; # Optional: Handle path rewriting if needed rewrite ^/report(/.*)?$ $1 break; } # Deny access to other paths location / { deny all; } # Handle other path requests if necessary # You can add additional location blocks for specific path requests } Explanation Allowing Access to /report: The location /report block forwards requests to the internal server http://192.168.1.1. The rewrite directive (optional) handles path rewriting to ensure that the /report prefix is not added to the internal server's request path. Denying Access to Other Paths: The location / block with the deny all; directive blocks access to all other paths. This means that external users will receive a 403…

both frontend and backend web development utilize a variety of open platforms and technologies. These platforms and tools provide a range of functionalities for building, testing, deploying, and maintaining web applications. Here are some commonly used open platforms and technology stacks in frontend and backend development: Frontend Development Frameworks and Libraries React: A JavaScript library developed by Facebook for building user interfaces, particularly suitable for single-page applications (SPA) and complex user interfaces. Angular: An open-source frontend framework maintained by Google for building dynamic web applications. Vue.js: A progressive JavaScript framework that is easy to learn and suitable for building single-page applications and complex user interfaces. Build Tools and Package Managers Webpack: A module bundler for packaging JavaScript and other assets, supporting code splitting and hot module replacement. Parcel: A zero-configuration web application bundler designed to provide a fast build and development experience. npm: A package manager for Node.js used to manage JavaScript libraries and tools. Yarn: Another popular package manager developed by Facebook, known for its fast installation speed and reliable dependency management. Styling Tools…

Today, something that made me quite happy happened—I finally finished building my own website. It might not seem like a big deal, but for me, it feels like a small adventure and achievement. The most interesting part was the learning and exploration throughout the process. Seeing the site evolve from nothing to what it is now has made me genuinely happy. Next, I plan to continue optimizing the site and learning more. Although this project is now complete, I know there are still many exciting things to explore in the future. I’d also like to extend my gratitude to serv00.com for providing such an excellent platform. So, I'm recording my feelings for today. It might not be a groundbreaking success, but this little joy is enough to keep me smiling all day.
