After modifying the/usr/local/webserver/nginx/conf/nginx. conf configuration file, run the following command to check whether the configuration file is correct:
#/Usr/local/webserver/nginx/sbin/nginx-t
If you test OK successfully, run the following command to restart Nginx:
(1st types) # pkill nginx
#/Usr/local/webserver/nginx/conf/nginx. conf
