nginx -t

Nginx-v or nginx-v

At this point, openResty’s nginx has been installed, the system has been switched to openResty, and restarted (nginx -s reload)nginx will read the configuration files in the openResty directory.

1.3 restart nginx

1.3.1 Specifying the startup configuration file mode

# conf-path=*path*:  -c file
nginx -s reload -c /etc/nginx/nginx.conf
Copy the code

If executed nginx -s reload restart nginx, note/usr/local/openresty/nginx/conf/nginx. The pid in the conf configuration items consistent with the history to install nginx configuration file

/configure --conf-path=/etc/nginx/nginx.conf installCopy the code

nginx -t

  • restart

nginx -s reload

Switch between openResty and Nginx
