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);// = FCGX_FPrintF(cgi.out,"%s",result);
}
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!”；
3、post和ajax测试：
1)、在2中的测试代码中加上：
void getData(FCGX_Request cgi){
const char * request_method;
request_method = FCGX_GetParam("REQUEST_METHOD", cgi.envp);
printf("request_method = %s \n",request_method);
if(0 == strcasecmp(request_method, "POST")){
printf("REQUEST_METHOD = POST\n");
const char *p_content_len =FCGX_GetParam("CONTENT_LENGTH", cgi.envp);
if (p_content_len != NULL) {
int len = atoi(p_content_len);
printf("%d \n",len);
if(len > 0){
char buf[len];
FCGX_GetStr(buf,len,cgi.in);
printf("%s\n",buf);
}
}
}
}
在main()中加上：
……
strcat(result, "</ul></body></html>\r\n");
getData(cgi);
FCGX_PutStr(result, strlen(result), cgi.out);
……
重新编译后复制到开发板对应目录；
2)、把index.html 复制到开发板的/home/pub/johnny/network/install/webpages/目录：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>lighttpd</title>
<script type="text/javascript" src="./Global/jquery.min.js"></script>
<script type="text/javascript" src="./Global/jquery.json.min.js"></script>
<script>
//test post
$.post("test.php", $.toJSON({method: "test"}), function(data) {
//var result = $.parseJSON(data);
console.log("test post sucess!");
console.log(data);
});
//test ajax
var post_data = $.toJSON({method : "test",data : "test"});
$.ajax({
type: 'POST',
url: 'test.php',
data: post_data,
success: function(data){
console.log("test ajax sucess!");
console.log(data);
},
timeout:1000,
error: function(){
console.log("ajax error!!!!");
}
});
</script>
</head>
<body>
<p>lighttpd fastcgi test(for mips-linux)</p>
<hr>
<p>this is a test</p>
</body>
</html>
3)、在PC上打开http://192.168.9.*/index.html，每次刷新网页，开发板打印：
testfastcgi: Receive Request!
request_method = POST
REQUEST_METHOD = POST
17
{"method":"test"}
testfastcgi: Receive Request!
request_method = POST
REQUEST_METHOD = POST
31
{"method":"test","data":"test"}
4、服务器压力测试：
在某台linux主机上输入：
ab -c 1000 -n 1000 http://192.168.8.*/test.php
会打印出测试的结果；
