How does NGINX match location?
First, Nginx looks for an exact match. If a location block using the = modifier is found to exactly match the request URI, this location block is immediately selected to serve the request. If no exact location block matches are found (with the = switch), Nginx skips to evaluating non-exact prefixes.

How can I have the same rule for two locations in the NGINX configuration?
The ~ means to use a regular expression for the url. The ^ means check from the first character. This will search for a / followed by any of the locations and then another / . Another option is to repeat the rules at two prefix locations using an included file.
How do I configure NGINX to serve static files?
To serve static files with nginx, you need to set the root directory path of your application and reference the HTML entry point as the index file. In this example, the root directory for the Snake deployment is /home/futurestudio/apps/snake, which contains all the files.
How does the regex-Nginx rule match all routes except one?
This works because when Nginx finds an exact match with an =, it uses that location to service the request. One problem is that this won’t match if you’re using an index page because the request is rewritten internally and so it will match the second “best” location and use that.
How to have the same rule for two locations in Nginx config?
This will search for a / followed by any of the locations and then another /. Another option is to repeat the rules at two prefix locations using an included file. Since prefix locations are independent of position in the configuration, using them can avoid some confusion as you add other regular expression locations later.
What is the location regular expression for Nginx Plus?
NGINX regular expression locations have the format: regex location { #… } For example, a location block with the following regular expression handles all PHP requests with a URI ending in myapp/filename.php, such as /test /myapp/hello.php and /myapp/hello.php. The asterisk after the tilde (~*) makes the match case-insensitive.
Is it better to include files or locations in Nginx?
The main advantage of including files (as far as I can tell) is that you are a bit more flexible about what exactly you can include; for example, it doesn’t have to be an entire location block. But it’s also subjectively a bit clunkier than named locations.
What regular expressions does NGINX use?
NGINX uses Perl Compatible Regular Expressions (PCRE).
What is the NGINX named location?
NGINX: Named Locations NGINX supports named locations. You can define the named location using the @ symbol. The named location is not used for regular request processing, but is used for request redirection. Validate and reload the nginx configuration.
What is location in NGINX conf?
Each NGINX configuration file will be found in the /etc/nginx/ directory, with the main configuration file located in /etc/nginx/nginx. conference
Is Nginx case sensitive?
nginx doesn’t support # setting absolutely everything to be case insensitive.
Is NGINX safe to use?
Nginx is a very secure and reliable web server even with default settings. However, there are many ways to further secure Nginx. In this article, we will use open source software exclusively while trying to follow some popular approaches to hardening web servers and security standards.
What sites are NGINX?
By default on Debian systems, Nginx server block configuration files are stored in the /etc/nginx/sites-available directory, which are enabled via symbolic links to the /etc/nginx/sites-enabled/ directory. .
How to create a location regular expression in Nginx?
NGINX regular expression locations have the format: regex location { #… } For example, a location block with the following regular expression handles all PHP requests with a URI ending in myapp/filename.php, such as /test /myapp/hello.php and /myapp/hello.php. The asterisk after the tilde (~*) makes the match case-insensitive. location ~* /myapp/.+//.php$ { #… }
How to select prefix location in Nginx?
The first regular expression location that matches the URI is immediately selected to process the request. If no regular expression locations are found that match the request URI, the previously stored prefix location is selected to serve the request.
How does Nginx find the longest matching prefix?
If there are any regex locations within the longest matching prefix location, Nginx will move them to the top of its list of regex locations to check. Nginx then tries to sequentially match the locations of the regular expressions.
Is there regular expression support in Nginx?
Regular expression support is one of the powerful features of NGINX, but regular expressions can be complex and hard to fix, especially if you don’t work with them regularly. NGINX allows regular expressions in various parts of a configuration, for example locations, maps, rewrites, and hostnames.
What does location do in NGINX?
The location directive within the NGINX server block allows the request to be routed to the correct location within the file system. The directive is used to tell NGINX where to look for a resource by including files and folders while comparing a location block to a URL.
What is location in NGINX configuration?
By default, the configuration file is named nginx. conf and placed in the /usr/local/nginx/conf , /etc/nginx , or /usr/local/etc/nginx directory.
Is Nginx case sensitive?
How does nginx process a request?
In this setup, nginx first tests the request’s IP address and port against the server’s block listening directives. It then tests the “Host” header field of the request against the server_name entries from the server blocks that matched the IP address and port.
What does NGINX Rewrite do?
Nginx rewrite rules can be defined within your Nginx configuration file to change at least part or all of a URL. Usually this is done for one of two purposes. First, if a URL has changed, using a rewrite rule will let the client know that the requested resource is in a different location.
How do I redirect a URL in NGINX?
Here are the steps to redirect location to another domain in NGINX.
- Open the NGINX configuration file. If you are using the main NGINX configuration file nginx.conf, without virtual hosts, run the following command $ sudo vi /etc/nginx/nginx.conf.
- Redirect location to another domain.
- Restart NGINX.
What is better Apache or NGINX?
NGINX is approximately 2.5 times faster than Apache based on the results of a benchmark running up to 1,000 concurrent connections. Another benchmark running with 512 concurrent connections showed NGINX to be about twice as fast and consume slightly less memory (4%).
What is Nginx Rewrite?
What type of regular expression is used in Nginx?
NGINX uses Perl Compatible Regular Expressions (PCRE). Before we get into the details of the regular expression tester, let’s first discuss how regular expressions can be used in NGINX locations and maps. NGINX regular expression locations are of the form:
How to use REGEXP on stack location?
Here, you must not escape the curly braces of the limiting quantifier, but you must tell NGINX to pass the curly braces as part of the regular expression pattern string. Here is a regular expression demo. the reason is that Nginx uses square brackets to define configuration blocks, so it thinks it’s opening a location block.
How does the location directive work in Nginx?
Nginx will first check for matching locations that are defined using the prefix strings. If the URL has a multiple location prefix string match, then Nginx will use the longest matching location prefix.
What is the root of the Nginx server?
The following will serve all the files for your Nginx server from a directory that you will define in the root under “location /”. For example, the following will serve the geekstuff.com/index.html file from the /var/www/html directory instead of the default nginx root location.
