xhprof 简单学习试用

使用centos 7 ，使用内置的php 以及结合php-fpm

安装

yum install -y nginx php-fpm xhprof

修改配置添加xhprof支持

• php.ini
  安装的位置在/etc/php.ini

 

[xhprof]

extension=xhprof.so

• nginx 配置

user nginx;

worker_processes auto;

error_log /var/log/nginx/error.log;

pid /run/nginx.pid;

​

include /usr/share/nginx/modules/*.conf;

​

events {

    worker_connections 1024;

}

​

http {

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '

                      '$status $body_bytes_sent "$http_referer" '

                      '"$http_user_agent" "$http_x_forwarded_for"';

​

    access_log  /var/log/nginx/access.log  main;

​

    sendfile            on;

    tcp_nopush          on;

    tcp_nodelay         on;

    keepalive_timeout   65;

    types_hash_max_size 2048;

​

    include             /etc/nginx/mime.types;

    default_type        application/octet-stream;

​

    # Load modular configuration files from the /etc/nginx/conf.d directory.

    # See http://nginx.org/en/docs/ngx_core_module.html#include

    # for more information.

    include /etc/nginx/conf.d/*.conf;

    server {

        listen       8090 default_server;

        server_name  _;

        root         /usr/share/xhprof/xhprof_html;

​

        # Load configuration files for the default server block.

        include /etc/nginx/default.d/*.conf;

​

        location / {

            index index.php index.html index.htm;

​

        }

        location ~ \.php$ {

            fastcgi_pass   127.0.0.1:9000;

            fastcgi_index  index.php;

            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

            include        fastcgi_params;

        }

​

        error_page 404 /404.html;

            location = /40x.html {

        }

​

        error_page 500 502 503 504 /50x.html;

            location = /50x.html {

        }

    }

​

    server {

        listen       8080 default_server;

        server_name  _;

        root         /var/www/;

        include /etc/nginx/default.d/*.conf;

        location / {

            index index.php index.html index.htm;

​

        }

        location ~ \.php$ {

            fastcgi_pass   127.0.0.1:9000;

            fastcgi_index  index.php;

            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

            include        fastcgi_params;

        }

​

        error_page 404 /404.html;

            location = /40x.html {

        }

​

        error_page 500 502 503 504 /50x.html;

            location = /50x.html {

        }

    }

​

}

• 测试代码

<?php

xhprof_enable();

// 以下为要分析的代码.

function showSleep($num = 5)

{

    $i = 0;

    while ($i++ < $num) {

        sleep(1);

    }

}

​

function genData($num = 100)

{

    $data = [];

    $i = 0;

    while ($i++ < $num) {

        $data[] = $i * $i;

    }

    sleep(4);

    return $data;

}

showSleep(6);

genData(100);

// 以上为要分析的代码.

// 获取分析结果.

$xhprofData = xhprof_disable();

// 引入xhprof_lib.

$xhprofRoot = '/usr/share/xhprof/';

include_once $xhprofRoot . "/xhprof_lib/utils/xhprof_lib.php";

include_once $xhprofRoot . "/xhprof_lib/utils/xhprof_runs.php";

​

// 保存结果.

$xhprofRuns = new XHProfRuns_Default();

$runId = $xhprofRuns->save_run($xhprofData, "xhprof_show");

// 输出报告地址.

echo 'http://host:port/index.php?run=' . $runId . '&source=xhprof_show';

效果

 

 

说明

自己对于php的内部机制不是很了解，以上只是一个简单的记录
