10、Nginx+Php-Fpm如何抗并发

标签：

PHP

1、环境准备

沿用之前”nginx与php-fpm结合详解”的配置信息，并启动

2、查看php-fpm的信息

配置信息

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3

进程数

3、编写测试文件

web文件-test.php

<?php
set_time_limit(0);
sleep(10);
echo “test.php->”.time();

测试文件-pcntl.php

<?php
function postXmlCurl($url,$xml=””,$second = 30)
{
$ch = curl_init();
//设置超时
curl_setopt($ch, CURLOPT_TIMEOUT, $second);
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,FALSE);//TRUE
curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,FALSE);//严格校验 2
//设置header
curl_setopt($ch, CURLOPT_HEADER, FALSE);
//要求结果为字符串且输出到屏幕上
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
//post提交方式
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
//运行curl
$data = curl_exec($ch);
//返回结果
if($data){
curl_close($ch);
return $data;
} else {
$error = curl_errno($ch);
curl_close($ch);
return “error->”.$error;
}
}
$count = 10;
$url = “http://127.0.0.1:81/test.php”;
$pidArr = array();
for ($i=0;$i<$count;$i++) {
$pid = pcntl_fork();
if ($pid<0) {
exit(“fork is error.”);
} elseif ($pid==0) {
echo posix_getpid().’–>’.postXmlCurl($url),PHP_EOL;
exit;
} else {
$pidArr[$pid] = $pid;
}
}
while (1) {
if (!count($pidArr)) {
echo “over”,PHP_EOL;
break;
}
$pid = pcntl_wait($status,WUNTRACED);
if ($pid>0) {
echo “{$pid} is over–>”,$status,PHP_EOL;
unset($pidArr[$pid]);
}
}
