Intro
Redirect is an excellent plugin that also comes with the functionality to export your redirects as Nginx rewrite rules (which is fancy talk for server-level redirects). You can use the plugin interface to build your redirects, export them, and add them at the server level as an include for better performance.
It’s great for catching URL changes on busy websites, as you can set up Redirection to automatically recreate redirects for posts/pages/custom post types as needed, and then add them in Nginx in batches as time goes by.
Step 1. Export Your Redirects
To export your redirects and add them to your GridPane server directly, log into your website and head to the Redirection page and click on “Import/Export” at the top.
Select “WordPress redirects” and “Nginx rewrite rules” from the dropdowns and click view:
Here you can either download them or simply leave the page open and copy and paste them in step 3.
Step 2. SSH into your server
Please see the following articles to get started:
Generate your SSH Key:
Generate SSH Key on Windows with Putty
Generate SSH Key on Windows with Windows Subsystem for Linux
Generate SSH Key on Windows with Windows CMD/PowerShell
Add your SSH Key to GridPane:
Add/Remove an SSH Key to/from an Active GridPane Server
Connect to your server:
Step 3. Create redirect-main-context.conf
We now need to create a file called redirect-main-context.conf inside /var/www/site.url/nginx and add your exported redirection code. Create the file with the following command (switching out site.url for your domain name):
nano /var/www/site.url/nginx/redirect-main-context.conf
Next copy and paste your rewrites only (and also the Redirection info as well if you wish – the date may come in handy).
Important: If the rewrites are added inside server { } it result in an Nginx syntax error.
# Created by Redirection
# Tue, 08 Dec 2020 18:33:41 +0000
# Redirection 4.9.2 - https://redirection.me
rewrite ^/test-example$ /sample-page permanent;
rewrite ^/another-example$ https://domain.com permanent;
# End of Redirection
Now Ctrl+O and then press enter to save the file. Then Ctrl+X to exit nano.
Step 4: Check and reload Nginx
Finally, we need to check if the conf files are correct then reload Nginx.
Test your nginx syntax with:
nginx -t
If there are no errors present, reload nginx with the following command:
gp ngx reload
