Iserver简介
Iserver是一个用python编写的网络服务框架（编译版本3.4.1），使用的是epool网络模型

开启8个nginx进程消耗120M内存（15M * 8 = 120M）

开启12个php-cgi进程消耗掉240M内存（20M * 12 = 240M）
测试流程
首先启动队列网络服务，php向队列服务里插入一条insert sql，例如
client.php
复制代码
1 /**
2 * socket client
3 * a NULL填充字符串
4 * n 表式无符号短整形
5 * 无符号短整型, 总是16点，大端字节序
6 */
7 function insert_queue($cmd, $sql) {
8 $s = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
9 try {
10 socket_connect($s, "127.0.0.1", 8888);
11 $list = json_encode(array(
12 "sql"=>$sql
13 ));
14 $len = strlen($list);
15 $param = pack("nna{$len}",$cmd, $len, $list);
16 socket_write($s, $param, strlen($param));
17 socket_recv($s, $head, 4, 0);
18 //var_dump($head);
19 if($head != '') {
20 $a = unpack("ncmd/nlen", $head);
21 $cmd = $a['cmd'];
22 $len = $a['len'];
23 if($cmd == 8001) {
24 socket_recv($s, $body, $len, 0);
25 //echo $body;exit;
26 $b = json_decode($body, true);
27 socket_close($s);
28 return $b;
29 }
30 }
31 socket_close($s);
32 } catch(Exception $e) {
33 echo $e->getMessage();
34 }
35 }
36 $temp = insert_queue(8001, "insert into (num) values (%d)");
