How to clear nginx cache manually ?

Normally I like to do manually job.

assume that the default path of your nginx cache is /var/cache/nginx

find /var/cache/nginx -type f -delete

This will clear all your cache in one line.

Delete a single file from nginx cache

If you just want to delete a single file from nginx cache, you can try this.

grep -lr '//juzhax.com/wp-content/plugins/jetpack/modules/wpgroho.js' /var/cache/nginx*

Then it will show something like this
/var/cache/nginx/8/45/6025f6b505cd8cbc1172d4e541ac3458

You can safely remove by using rm

rm /var/cache/nginx/8/45/6025f6b505cd8cbc1172d4e541ac3458

Solution to solve

Add this into your functions.php in your theme.
You can access from Apperance –> Editor
Then you try to to put this code to update the file.

function _remove_script_version( $src ){
$parts = explode( '?', $src );
return $parts[0];
}
add_filter( 'script_loader_src', '_remove_script_version', 15, 1 );
add_filter( 'style_loader_src', '_remove_script_version', 15, 1 );
