How to Redirect to A Custom Url With Nginx?

To redirect to a custom URL with nginx, you can utilize the return directive in your server block configuration. Simply specify the desired HTTP status code (e.g., 301 for permanent redirection) followed by the URL you want to redirect to. For example, to redirect all traffic from example.com to newexample.com, you can add a return 301 https://newexample.com$request_uri; line in the server block for example.com. Make sure to reload nginx configuration after making changes.

How to redirect to a custom URL with nginx and preserve query strings?

To redirect to a custom URL with nginx and preserve query strings, you can use the following configuration:

1. Create a new server block in your nginx configuration file:

1
2
3
4
5
6
7
8

server {
    listen 80;
    server_name example.com;

    location / {
        return 301 $scheme://newwebsite.com$request_uri;
    }
}

1. In this configuration, replace example.com with the domain you want to redirect from and newwebsite.com with the custom URL you want to redirect to.
2. The $request_uri variable preserves the query strings in the URL during the redirection process.
3. Save the configuration file and then restart nginx to apply the changes.

1

sudo systemctl restart nginx

Now, when a user visits example.com/test?a=1&b=2, they will be redirected to newwebsite.com/test?a=1&b=2 while preserving the query strings.

How to create a dynamic redirect in nginx?

To create a dynamic redirect in Nginx, you can use the rewrite directive along with regular expressions to match the URLs that need to be redirected. Here's an example of how you can create a dynamic redirect in Nginx:

1. Open your Nginx configuration file (usually located in /etc/nginx/nginx.conf or /etc/nginx/sites-available/default).
2. Inside the server {} block, add a rewrite directive with a regular expression pattern that matches the URLs you want to redirect. For example, if you want to redirect all URLs that start with /old-page to a new URL, you can use the following directive:

1

rewrite ^/old-page/(.*)$ /new-page/$1 permanent;

In this example, ^/old-page/(.*)$ is the regular expression pattern that matches any URL that starts with /old-page/, and /$1 is the new URL where the request should be redirected. The permanent flag indicates that this is a permanent redirect (HTTP status code 301).

1. Save the configuration file and reload Nginx to apply the changes:

1
2

sudo nginx -t
sudo systemctl reload nginx

Now, when a user requests a URL that matches the pattern /old-page/, Nginx will dynamically redirect them to the corresponding URL in /new-page/. You can customize the regular expression pattern and the new URL to suit your specific redirect requirements.

How to redirect based on browser type in nginx?

To redirect based on browser type in Nginx, you can use the Nginx ngx_http_browser_module. Here's an example of how you can redirect users based on their browser type:

1. First, you need to install the Nginx ngx_http_browser_module. If you are using a package manager like apt or yum, you can install it using the following commands:

For apt:

1

sudo apt-get install nginx-extras

For yum:

1

sudo yum install nginx-module-njs

1. Now, you need to add the following code to your Nginx configuration file:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
19
20
21
22

http {
    // Add this condition to your server block
    map $http_user_agent $is_mobile {
        ~* (mobile|android) 1;
        default 0;
    }

    server {
        // Add your server configurations here

        location / {
            if ($is_mobile) {
                return 301 /mobile;
            }
            // Add your regular configurations here
        }

        location /mobile {
            // Add configurations for mobile users here
        }
    }
}

In this code, we are using the $is_mobile variable to check if the user's user agent contains the words "mobile" or "android". If the condition is met, the user will be redirected to the /mobile location. You can modify this code to check for other types of browsers as well.

1. Finally, you need to reload your Nginx configuration for the changes to take effect:

1

sudo systemctl reload nginx

With these steps, you can redirect users based on their browser type in Nginx.

How to redirect a domain to another domain with nginx?

To redirect a domain to another domain using NGINX, you can create a server block for the original domain and use the return directive to issue a 301 redirect status code. Here is an example configuration:

1. Open your NGINX configuration file, typically located in /etc/nginx/nginx.conf or /etc/nginx/sites-available/.
2. Add a new server block for the original domain:

1
2
3
4
5
6

server {
    listen 80;
    server_name example.com;
    
    return 301 http://www.newdomain.com$request_uri;
}

1. In this configuration, replace example.com with the original domain you want to redirect and www.newdomain.com with the new domain you want to redirect to.
2. Save the configuration file and exit the text editor.
3. Test the configuration to ensure there are no syntax errors:

1

sudo nginx -t

1. If the test is successful, reload NGINX to apply the changes:

1

sudo systemctl reload nginx

Now, when users visit example.com, they will be automatically redirected to www.newdomain.com.

How to set up a custom URL redirect in nginx?

To set up a custom URL redirect in nginx, you can create a new server block in your nginx configuration file and use the rewrite directive to specify the custom URL redirect.

Here is an example of how to set up a custom URL redirect in nginx:

1. Open your nginx configuration file (usually located at /etc/nginx/nginx.conf or /etc/nginx/sites-enabled/default).
2. Add a new server block for the domain you want to set up the custom redirect for. For example:

1
2
3
4
5
6
7

server {
    listen 80;
    server_name example.com;
    location / {
        rewrite ^/old-url$ /new-url permanent;
    }
}

1. In the location / block, use the rewrite directive to specify the old URL and the new URL you want to redirect to. In the example above, ^/old-url$ is the old URL and /new-url is the new URL. The permanent flag at the end of the rewrite directive specifies that the redirect is a permanent (301) redirect.
2. Save the configuration file and reload nginx to apply the changes:

1

sudo systemctl reload nginx

After setting up the custom URL redirect in nginx, any requests to example.com/old-url will be redirected to example.com/new-url. You can test the redirect by entering the old URL in a browser and verifying that it redirects to the new URL.
