Service Nginx Can Not Start

Why Nginx Won’t Start Up After Installing It?

When attempting to start up Nginx after installing it, some users may encounter an error message saying that the service won’t start. This can be caused by a few different issues, depending on the exact setup of an individual’s system. Before panicking and trying to troubleshoot, it’s important to understand why Nginx might not start up and how to find the root cause of the issue.

First, it’s important to understand that Nginx is an open-source web server software, largely used for powering high-traffic websites such as YouTube or Reddit. It’s built for speed and scalability, and is known for its light resource usage. As such, Nginx is an excellent choice for running a website, even with the occasional bump in the road like the one in question.

Common Reasons Why Nginx Won’t Start Up

Generally speaking, there are three main categories of reasons why Nginx won’t start up, each with its own set of possible contributing factors. It is important to note, however, that the actual cause will vary depending on the system and its environment.

The most common reason why Nginx fails to start up is an issue with its configuration. The configuration file is essentially a list of instructions telling Nginx how to operate, and any syntax errors or typos can cause it to fail. As such, it’s important to check the configuration file for any errors first.

Another possible cause is a lack of permission. Nginx needs the appropriate permission to run, and if it does not receive them then it will fail or be unable to start. This can be checked and modified in the system’s user interface, depending on the operating system in question.

Finally, there might also be an issue with the system itself. Nginx needs to be able to access certain files and ports in order to run, and any incompatibilities or blocked access can prevent it from properly starting up. Check with the system administrator or look up online to see if there are any known system-wide issues that might be affecting Nginx.

Steps To Correctly Troubleshoot Nginx’s Startup Problem

Now that the possible categories of causes are out of the way, let’s go over the steps needed to correctly troubleshoot and possibly fix the issue. It is important to do each of these steps properly, so make sure to read the exact instructions appropriate for your system’s version of Nginx.

The first step is to check for syntax errors in the configuration file. As mentioned before, this is essentially a list of instructions telling Nginx how to behave, and any typos can lead to a failure in functionality. Any errors in the configuration file will need to be corrected before Nginx can start up.

The next step is to check the permissions settings for Nginx. As mentioned before, Nginx needs permission to access certain files and ports in order to function properly. If these are not present or set up incorrectly, then Nginx will not be able to start. Check the permissions, and if necessary adjust them to the appropriate settings.

One final step, if all the above do not fix the issue, is to check the system itself, both software and hardware related. See if there are already any known system-wide issues, or if there are any outdated drivers or software that could be causing any conflicting problems. Nginx can also be blocked by certain firewalls or antivirus programs, so also check these to see if they might be the cause.

What to Do After Troubleshooting?

After completing the steps outlined in the previous section, Nginx should start up properly. However, if the problem persists then there could be a deeper issue at play, or something that is difficult to troubleshoot without expert help. In this case, it is best to contact a professional in order to properly diagnose and fix the issue.

Another thing to consider is the fact that Nginx is an open-source software, which means that there is no direct support from the developers themselves. Instead, the Nginx community is full of experts willing to help with any issue, so look around online and see if somebody has already figured out a solution.


In conclusion, knowing why Nginx might not start up and how to troubleshoot the issue is essential for any system administrator. Whether the cause is a syntax error in the configuration file, incorrect permissions settings, or a system-wide problem, it’s important to follow the proper steps and take into account the limitations of using open-source software.
