The steps to install Apache on Ubuntu or Debian include: 1. Update the system software package to ensure the latest software source; 2. Run sudoaptininstallapache2 to install the Apache service and check its running status; 3. Configure the firewall to allow HTTP/HTTPS traffic; 4. Adjust the website file path, modify the configuration or enable the module as needed; 5. Restart the Apache service after modifying the configuration and taking effect. The whole process is simple and direct, but you need to pay attention to key points such as permission settings, firewall rules and configuration adjustments to ensure that Apache works normally and can access the default page through the browser.

Enable HSTS to force browsers to access websites through HTTPS, improving security. 1. To enable HTTPS in Apache, you must first configure HTTPS, and then add Strict-Transport-Security response header in the site configuration file or .htaccess; 2. To configure max-age (such as 31536000 seconds), includeSubDomains and preload parameters; 3. Make sure that the mod_headers module is enabled, otherwise run sudoa2enmodheaders and restart Apache; 4. You can optionally submit to the HSTSPreload list, but it must satisfy that both the main site and the subdomain support HTTPS.

VSCode has built-in Git function, which can complete most daily version control tasks directly in the editor. Its core answers and detailed descriptions are as follows: 1. Provide sidebar integration, view and modify files, temporarily store changes and resolve conflicts through Git icons; 2. Support line-level change tracking, showing who modified the code when; 3. Simple operation of submission and synchronization, input shortcut keys after submitting information, and can be pushed or pulled from the menu; 4. Easy branch switching, click the status bar branch indicator to select local or remote branches; 5. Support remote management, add remote warehouses through the command panel and automatically set up upstream branches. These features cover 90% of daily use scenarios without additional tools.

To have Apache serve a simple HTML file, first prepare the HTML file and put it in the correct directory. 1. Create a simple HTML file such as index.html or example.html; 2. Copy the file to Apache default root directory /var/www/html/ or custom path; 3. Make sure the Apache service is started and accessed through the browser to test; 4. If you need to change the website directory, modify the DocumentRoot and Directory paths in the Apache configuration file, and restart the service to make the configuration take effect. The entire process requires attention to the file extension, path permissions and service status, and ensure that all settings are accurate and the page can be displayed successfully.

Apache's default web root directory is /var/www/html in most Linux distributions. This is because the Apache server provides files from a specific document root directory. If the configuration is not customized, systems such as Ubuntu, CentOS, and Fedora use /var/www/html, while macOS (using Homebrew) is usually /usr/local/var/www, and Windows (XAMPP) is C:\xampp\htdocs; to confirm the current path, you can check the Apache configuration file such as httpd.conf or apache2.conf, or create a P with phpinfo()

To force delete an unmerged Git branch, use the gitbranch-D command. This command ignores the merge status of the branch and deletes it directly. It is suitable for useless branches after testing, abandoned feature branches, or local old branches that need to be recreated from remotely. However, it should be noted that the submission record will still exist locally after deletion and will eventually be cleaned up by the garbage collection mechanism; after mistaken deletion, it can be restored through gitreflog, but the window period is short. Therefore, before execution, be sure to confirm that the branch is useless, uncooperated and the name is correct to avoid data loss.
