Run Nginx on Kernel or Light Stack

1. Set the size of webpage file

sudo ./set_webpage_size.sh <file_size_in_byte>

2. Run nginx on either Kernel stack or Light stack

(1) Run nginx on Kernel stack:

sudo ./nginx_nworker_kernel.sh <worker_num>

(2) Run nginx on Light stack:

sudo su
export LIGHT_SOURCE_PATH=<path_to_Light>
./nginx_nworker_Light.sh <nginx_worker_num>

The Light frontend module (FM) dynamic library light_h6.so is created from the source file light_h.c, which contains the network APIs of Light with POSIX semantics. By leveraging LD_PRELOAD mechanism, the Light FM dynamic library has a higher priority than the default GNU C Library. Thus when an application invokes network-related APIs, such as socket(), listen(), bind(), Light could take over and process them.

Note: if you get the following error, you need to restart Light and nginx.
