Simulate Nginx service startup and shutdown

Known Nginx management commands are:

Start: / application/nginx/sbin/nginx

Stop: / application/nginx/sbin/nginx-s stop

Reload: / application/nginx/sbin/nginx-s reload

Use the case script to simulate Nginx service startup and shutdown:

/ etc/init.d/nginx {start | stop | reload | restart}, which can be managed through chkconfig.
