Can you use .htaccess with Nginx?

The two biggest industry players in the field of web servers are the Apache HTTP Server and Nginx. Both systems have their pros and cons and are suitable for different web projects. Unfortunately, they are only partially compatible. This could be particularly problematic when switching servers. One of the big questions when moving from Apache to Nginx is: Can the .htaccess file be used on Nginx?

What is a .htaccess file?

The htaccess is a small text file where various directory-related configurations are stored on an Apache HTTP Server. For example, specific access rights for individual files or directories can be defined.

In addition, the htaccess can serve many other purposes:

• Creating password-protected areas: With htaccess, it is possible to protect individual directories or files with a password to prevent unauthorized access.
• Creating custom error pages: Standard error pages can be customised.
• Redirects: Redirects can be created to individual files on the server or to another domain.
• Increasing the PHP memory limit: The PHP memory limit can also be defined in the file.
• Blocking IP addresses: If access to the website needs to be denied to certain IP addresses, this can be done through a command in the htaccess file.
• Changing the web server's timezone: For international web projects, it may be useful to have a different timezone on the server than the server's location. This can also be set in the .htaccess file.

We have already compiled many more useful tips on how the .htaccess file works elsewhere.

Creating the .htaccess file

To create the configuration file, all you need is a text editor. Open it, enter the desired commands, and save the file with the name ".htaccess". Note: Do not forget the dot at the beginning of the filename.

Once the file is saved locally, it can be uploaded to the web server via FTP.

Compatibility with Nginx

Especially with extensive configurations made in the .htaccess file, the question arises whether the file can be transferred when moving from a hosting with Apache HTTP Webserver to Nginx web hosting.

The short answer is: No, not directly. The file itself is only compatible with the Apache HTTP Webserver.

This is mainly due to the different functioning of the two servers, as Nginx does not process requests on a directory basis. This provides the server with performance advantages. However, it does not support configurations for individual directories. More information on the differences between both systems can be found in the article Apache vs. Nginx.

Nevertheless, there is a way to transfer the settings made in the .htaccess file to Nginx. For this, the commands for configuring the Apache server need to be transferred to the nginx.conf file. However, since Nginx uses a different syntax, the commands need to be converted first. Various online converters, such as the tool from winginx.com, are available for this purpose. After transferring the configurations, it is important to manually verify that the server's functionality is ensured and the desired settings work.

Another way to restrict access rights to specific areas on the server with Nginx is to set up HTTP Basic Authentication. For this, an htpasswd file is created, configured, and placed on the web server. The directive auth_basic can then protect a specific file from unauthorized access.

Therefore, most configurations that can be set up on the Apache HTTP Webserver can also be functional on Nginx. They just need to be inserted in a different place and in a different form.
