FastCGI的编译跟移植 _CGI

FastCGI的编译和移植

1、编译和安装：

1)、下载：从http://www.fastcgi.com/drupal/下载fcgi.tar.gz；

2)、解压：tar xzvf fcgi.tar.gz

3)、配置：

./configure --prefix=/home/pub/johnny/network/install-fcgi --host=mips-linux-gnu --disable-FEATURE --without-PACKAGE "CC=mips-linux-gnu-gcc -EL" "CFLAGS=-EL" "LDFLAGS=-EL" "CXX=mips-linux-gnu-g++ -EL" "CXXFLAGS=-EL"

4)、make；在make时出现以下错误：

fcgio.cpp: In destructor 'virtual fcgi_streambuf::~fcgi_streambuf()':
fcgio.cpp:50: error: 'EOF' was not declared in this scope
fcgio.cpp: In member function 'virtual int fcgi_streambuf::overflow(int)':
fcgio.cpp:70: error: 'EOF' was not declared in this scope
fcgio.cpp:75: error: 'EOF' was not declared in this scope
fcgio.cpp: In member function 'virtual int fcgi_streambuf::sync()':
fcgio.cpp:86: error: 'EOF' was not declared in this scope
fcgio.cpp:87: error: 'EOF' was not declared in this scope
fcgio.cpp: In member function 'virtual int fcgi_streambuf::underflow()':
fcgio.cpp:113: error: 'EOF' was not declared in this scope

解决办法：
在/include/fcgio.h文件中加上 #include <cstdio>，然后再编译安装就通过了。
是由于GCC版本问题导致。

5)、make install；

在/home/pub/johnny/network/install-fcgi有 bin/、include/、lib/三个文件夹；

copy到开发板上；

2、测试：

1)、代码：

http://redmine.lighttpd.net/projects/lighttpd/wiki/Docs_ModFastCGI

#include <stdlib.h>
#include <string.h>
#include <syslog.h>
#include <alloca.h>
#include <fcgiapp.h>
#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);
		syslog(LOG_INFO, "Receive Request!");
                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, "<html><head><title>testcgi</title></head><body><ul>\r\n");

                for (envp = cgi.envp; *envp; ++envp) {
                        strcat(result, "<li>"); 
                        strcat(result, *envp); 
                        strcat(result, "</li>\r\n");
                }

                strcat(result, "</ul></body></html>\r\n");
                FCGX_PutStr(result, strlen(result), cgi.out);
        }

        return 0;
}

编译：

mips-linux-gnu-gcc -EL -I/home/pub/johnny/network/install-fcgi/include -L/home/pub/johnny/network/install-fcgi/lib -lfcgi testfastcgi.c -o test.fastcgi

2)、copy到开发板tmp/bin/下；

3)、修改conf.d/fastcgi.conf：

fastcgi.server = (
        "/test.php" =>
        ((
                "socket" => "/tmp/lighttpd.player.server.socket",
                "bin-path" => "/tmp/bin/test.fastcgi",
                "max-procs" => 1,
#               "host" => "127.0.0.1",
#               "port" => 8081,
                "check-local" => "disable",
        ))
)

4)、在PC上运行http://192.168.9.*/test.php，在网页上显示fastcgi的运行环境，而且每刷新一次网页，打印一次“Receive Request!”；
