How to Access Error Log files in Ubuntu Server?

One of the best things that I love about Ubuntu or any Linux based cloud server operating system is the ability to store all the logs and records. Whether it’s an error log, access log, or authentication log, the cloud server stores every in and out records.

One of the types of the record is the Error Log that store the information about all the issue a user or any web application has encountered when retrieving the site. It may be 400, 500, or any failed status codes.

All the logs are generally located under the /var/log directory folder. These files can be read and understood just like normal text files.

For example, I blocked the directory browsing externally using the Nginx security snippets. Now whenever any malicious user tries accessing the blocked directory or folder, a 403 forbidden status code will be appearing.

Since this is an error message for the end-user, Nginx will record the details like IP address of the malicious user, access date, page, what was the reason for the error, etc. etc. into an /var/log/nginx/error.log file.

Similarly, if you have any other issue with database connection, or PHP server not responding. These all records are also logged into the respective log files.

These log files are extremely helpful for a system administrator to understand the exact issue behind the error message. This will be also used for rectifying the problem after getting the support.

I personally contacted the DigitalOcean support and they are very helpful. They typically respond to any ticket within a day. While they do not have the live chat option, but given the complexity of the issues, it’s not feasible to have a live chat.
