fcgi-function

fcgi-function is a C/CPP service interface, It is a Service Interface build on top of FastCGI and Nginx which provided function handler support, it also provided useful collection tools to enhance the facilities.

Prerequisition Installed

Nginx -- https://www.nginx.com/

fcgi library -- https://github.com/FastCGI-Archives/FastCGI.com

cmake and make

Supported OS: LINUX, MAC OSX

Step of installation

1. Go to root directory

2. type

mkdir build (if not existed)

cd build

cmake ..

make

sudo make install

3. the result will be

Install the project...

-- Install configuration: ""

-- Installing: /usr/local/lib/libcsif.dylib

4. build a simple program by execute

gcc ../services_sample/profile_service.c -lcsif -lfcgi -rdynamic -o simple_service

For C++

g++ -std=c++11 ../services_sample/cpp_profile_service.cpp -lcsif -lfcgi -rdynamic -o simple_service

5. when you type

./simple_service

it will result:- Available options:

-a	the ip address which binding to

-p	port number to specified, not for -s

-s	unix domain socket path to generate, not for -p

-q	number of socket backlog

-w	number of worker process

-l	log file path

-e	signal handling

-f	Fork Daemon process

-d	Run on debug Mode

-o	Dynamic Link shared object file

-h	display usage

-v	display version

6. simple start a service by execute

./simple_service -p2005 -q200 -w200 -d

7. Edit the nginx.conf in your nginx config folder by append in your server block:-

location /getProfile {
  add_header Allow "GET, POST, HEAD" always;
  if ( $request_method !~ ^(GET|HEAD)$ ) {
    return 405;
  }
  include /etc/nginx/fastcgi_params;
  fastcgi_param FN_HANDLER getProfile;
  fastcgi_pass 127.0.0.1:2005;
}

location /postProfile {
  add_header Allow "GET, POST, HEAD" always;
  if ( $request_method !~ ^(POST)$ ) {
    return 405;
  }
   include /etc/nginx/fastcgi_params;
  fastcgi_param FN_HANDLER postProfile;
  fastcgi_pass 127.0.0.1:2005;
}

You will see the FN_HANDLER is function name mapping with the function inside simple_service code, the fastcgi port 2005 is the service you start with(please look at step 10 for more details.

8. start the nginx server

9. Using apache benchmark for get request load test

ab -c 100 -n 10000 http://127.0.0.1:80/getProfile

For post request load test

ab -p "payload.txt" -T application/json -c 100 -n 10000 http://127.0.0.1:80/postProfile

the payload.txt is inside the root directory

To uninstall.

1. Go to root_directory/build folder -- make sure build content is still existed.

2. type "sudo make uninstall"

Then result

-- Uninstalling /usr/local/lib/libcsif.dylib

-- Uninstalling /usr/local/lib/libcsif.a

-- Uninstalling /usr/local/include/csif/csif.h

-- Uninstalling /usr/local/include/csif/csif_json.h
