配置Lighttpd,使其能执行C语言写的FastCGI程序

vi lighttpd.conf

1.添加允许执行的FastCGI扩展名

static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" , ".cgi", "fastcgi")

 

2.增加Lighttpd能够解析FastCGI服务的语句

fastcgi.server            = (
        "/test" => (
          "test.fastcgi.handler" => (
     "socket" => "/tmp/test.fastcgi.socket",
     "check-local" => "disable",
     "bin-path" => "/data/www/webroot/cgi-bin/test.fastcgi",
     "min-procs" => 1,
     "max-procs" => 30,
     "idle-timeout" => 30
          )
        )
                            )

3.编写C的FastCGI

// gcc -I/usr/include/fastcgi -lfcgi testfastcgi.c -o test.fastcgi
#include 
#include 
#include 
#include 
#include 
#define LISTENSOCK_FILENO 0
#define LISTENSOCK_FLAGS 0
int main(int argc, char** argv) {
  openlog ("testfastcgi", LOG_CONS|LOG_NDELAY, LOG_USER);
  int err = FCGX_Init (); /* call before Accept in multithreaded apps */
  if (err) { syslog (LOG_INFO, "FCGX_Init failed: %d", err); return 1; }
  FCGX_Request cgi;
  err = FCGX_InitRequest(&cgi, LISTENSOCK_FILENO, LISTENSOCK_FLAGS);
  if (err) { syslog (LOG_INFO, "FCGX_InitRequest failed: %d", err); return 2; }
  while (1) {
    err = FCGX_Accept_r(&cgi);
    if (err) { syslog (LOG_INFO, "FCGX_Accept_r stopped: %d", err); break; }
    char** envp;
    int size = 200;
    for (envp = cgi.envp; *envp; ++envp) size += strlen(*envp) + 11;
    char*  result = (char*) alloca(size);
    strcpy (result, "Status: 200 OK\r\nContent-Type: text/html\r\n\r\n");
    strcat (result, "
\r\n");
    for (envp = cgi.envp; *envp; ++envp) {
      strcat(result, "
"); 
      strcat(result, *envp); 
      strcat(result, "
\r\n");
    }
    strcat(result, "
\r\n");
    FCGX_PutStr(result, strlen(result), cgi.out);
    FCGX_Finish_r(&cgi);
  }
  FCGX_ShutdownPending();
  return 0;
}

4.编译并运行

gcc -I/usr/include/fastcgi -lfcgi testfastcgi.c -o test.fastcgi

在IE中输入:

如果成功,即可看到如下信息:
