Apache's performance and flexibility make it stand out in a web server. 1) Performance advantages are reflected in efficient processing and scalability, which are implemented through multi-process and multi-threaded models. 2) Flexibility stems from the flexibility of modular design and configuration, allowing modules to be loaded and server behavior adjusted according to requirements.

When the Apache 80 port is occupied, the solution is as follows: find out the process that occupies the port and close it. Check the firewall settings to make sure Apache is not blocked. If the above method does not work, please reconfigure Apache to use a different port. Restart the Apache service.

Apache cannot start because the following reasons may be: Configuration file syntax error. Conflict with other application ports. Permissions issue. Out of memory. Process deadlock. Daemon failure. SELinux permissions issues. Firewall problem. Software conflict.

To set up a CGI directory in Apache, you need to perform the following steps: Create a CGI directory such as "cgi-bin", and grant Apache write permissions. Add the "ScriptAlias" directive block in the Apache configuration file to map the CGI directory to the "/cgi-bin" URL. Restart Apache.

There are 3 ways to view the version on the Apache server: via the command line (apachectl -v or apache2ctl -v), check the server status page (http://<server IP or domain name>/server-status), or view the Apache configuration file (ServerVersion: Apache/<version number>).

To restart the Apache server, follow these steps: Linux/macOS: Run sudo systemctl restart apache2. Windows: Run net stop Apache2.4 and then net start Apache2.4. Run netstat -a | findstr 80 to check the server status.
