Testing Apache Server to Ensure Successful Installation

Once you have completed installing and configuring Apache on your Ubuntu server, it's critical to test the server to ensure everything is functioning correctly. This ensures that your setup is robust and ready for deployment or further configuration. In this guide, let's explore the steps involved in verifying the successful installation of Apache.

Verify Apache Service Status

First and foremost, check if the Apache service is running. Use the following command in your terminal:

sudo systemctl status apache2

• Look for a "running" status. If it's active, your service is up and running.

Access Default Apache Web Page

Next, confirm that Apache is serving web pages correctly. Open a web browser and enter your server's IP address:

http://your-server-ip-address/

• A successful setup will display the default Apache "It Works!" page, indicating that the web service is operating.

Test Localhost Access

From the server itself, you can also test Apache by accessing the local host:

• Execute: curl http://localhost or curl http://127.0.0.1
• You should see the HTML code of the Apache default page, verifying local access.

Confirm Port Listening

Ensure that Apache is listening on the correct port, typically port 80 for HTTP traffic. Use the following command:

sudo netstat -tuln | grep :80

• If port 80 is listed, Apache is properly configured to listen for incoming connections.

Use Apache Bench for Load Testing

For IT professionals aiming for a more thorough test, Apache Bench (ab) can help simulate requests to your server:

ab -n 100 -c 10 http://your-server-ip-address/

• This command sends 100 requests with a concurrency of 10, helping evaluate your server's performance under load.

Log Analysis

Finally, check Apache's access and error logs for any anomalies or errors:

• Access log: /var/log/apache2/access.log
• Error log: /var/log/apache2/error.log

Regularly reviewing these logs can provide insights into the server's performance and any potential issues that need addressing.

By following these steps, IT professionals can effectively confirm the successful installation of Apache, ensuring that their Installing and Configuring Apache on Ubuntu Server: Step by Step Guide was executed flawlessly.
