In this issue, the editor will bring you about the methods to achieve 301 redirection in Nginx. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

First: use the rewrite instruction to regularly match all URI and then remove the first / (backslash).

Rewrite ^ / (. *) $https://www.hi-linux.com/$1;

The second: also use the rewrite instruction, except that all URI are matched through the $request_uri variable.

Rewrite ^ https://www.hi-linux.com$request_uri? Permanent

The advantage of this writing is that it saves the process of removing the first backslash at the beginning, and the performance of regular matching is better.

The third: use the return instruction to tell Nginx directly that this is a 301 redirect and grab the specified URI through the 301 status code and the $request_uri parameter.

Return 301 https://www.hi-linux.com$request_uri;

This method is the best in performance because rewrite instructions have a lot of writing and rules, and only after performing all regular matches will Nginx know that this is a 301 permanent redirection.
