php向队列服务里插入一条insert sql例如

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

测试机配置

处理器 2x Genuine Intel(R) CPU T2050 @ 1.60GHz

内存 2060MB (673MB used)

nginx开启进程数

root 2413 2409 0 09:17 pts/0 00:00:00 grep -i nginx

www 2414 2411 2 09:17 ? 00:00:00 nginx: worker process

www 2415 2411 0 09:17 ? 00:00:00 nginx: master process

www 2416 2411 0 09:17 ? 00:00:00 nginx: master process

www 2417 2411 0 09:17 ? 00:00:00 nginx: master process

www 2418 2411 0 09:17 ? 00:00:00 nginx: master process

www 2419 2411 0 09:17 ? 00:00:00 nginx: master process

www 2420 2411 0 09:17 ? 00:00:00 nginx: master process

www 2421 2411 0 09:17 ? 00:00:00 nginx: master process

开启8个nginx进程消耗120M内存（15M * 8 = 120M）

<pphp-cgi 开启进程数

root 2424 1 0 09:17 ? 00:00:00 php-fpm: master process

www 2425 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2426 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2427 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2428 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2429 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2430 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2431 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2432 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2433 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2434 2424 0 09:17 ? 00:00:00 php-fpm: pool www

www 2435 2424 0 09:17 ? 00:00:00 php-fpm: pool www

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)");
