How do i check the syntax after changing the nginx configuration file?

This checks the /etc/nginx/conf.d/* files too.

     -t             Do not run, just test the configuration file.  nginx checks the configuration file
                    syntax and then tries to open files referenced in the configuration file.

    -T             Same as -t, but additionally dump configuration files to standard output.

$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

If your configuration file is not the default one:

     -c file        Use an alternative configuration file.

$ sudo nginx -t -c /etc/nginx/mynginx.conf
nginx: the configuration file /etc/nginx/mynginx.conf syntax is ok
nginx: configuration file /etc/nginx/mynginx.conf test is successful
