The method of building PHP7 performance test environment

Objective

I used to analyze the xhprof+xhgui performance of the online environment, but PHP after the upgrade to the version is PHP 7 xhprof not available, so instead tideways+xhgui , this is actually the PHP7 only option for the next open source solution, interested in the resources can be seen, detailed description.

This article is mainly based on the reference [1] configuration, so there will be a lot of duplication of places, I mainly based on the requirements of the actual production environment to add the following additional configuration:

• mongodbBind only to Local

• xhguiTurn on HTTP Basic authentication

• xhguimongodbKeep only 14 the last days of data in

System environment

CentOS 7.3 + nginx + mysql + php71

This article assumes that your lnmp environment is already working, and that it is installed through the source code PHP , and now you just need to add the functionality of the performance test. If you are unfamiliar with the configuration of the lnmp environment, we recommend using the one-click installation package provided by https://lnmp.org/, which is based on the default configuration of the package.

Installation and Configuration

Into the following sections:

1. Mongodb

2. Tideways

3. Xhgui

4. Application Configuration

1.mongodb

Installation

#yum Install mongodb-server mongodb-y#pecl Install MongoDB

Start the mongodb service

#mongod--bind_ip 127.0.0.1

2.tideways

Installation

git clone https://github.com/tideways/php-profiler-extension.gitcd php-profiler-extensionphpize./configure-- with-php-config= ' which php-config ' Makesudo make install

Configuration

php.inito edit a file, add:

Extension=tideways.sotideways.auto_prepend_library=0

Restart php-fpm , execute the following command to see tideways the output indicated to be effective:

#php-M | grep tidetideways

3.xhgui

xhguiAlso a website that ultimately needs to be web accessed through. The official version of the English version, has not been updated, there are many BUG , it is recommended to use the Chinese version: https://github.com/maxincai/xhgui .

Install (assuming that the /home/wwwroot/ following commands are executed in the directory)

$ git clone https://github.com/maxincai/xhgui.git$ cd xhgui$ php install.php

Configuration

1. Adding an index to a database is not required, but strongly recommended:

$ MONGO > Use xhprof > Db.results.ensureIndex ({' Meta. SERVER. Request_time ':-1}) > Db.results.ensureIndex ({' Profile.main (). WT ':-1}) > Db.results.ensureIndex ({' Profile . Main (). Mu ':-1}) > Db.results.ensureIndex ({' Profile.main (). CPU ':-1}) > Db.results.ensureIndex ({' Meta.url ': 1})

2. nginx configuration ( xhgui There is no security mechanism in itself, it captures sensitive data in the data, so you must turn on HTTP Basic authentication after opening to the outside network)

Create /usr/local/nginx/conf/vhost/xhgui.conf the file with the following content:

server{    listen 8888; # change to its own port server_name 127.0.0.1 according to the actual situation    ; #根据实际情况改成自己的域名    index index.html index.htm index.php;    Root  /home/wwwroot/xhgui/webroot/;    Location ~ \.php    {        auth_basic "Xhgui needs Authentication"; # Open HTTP Basic authentication        auth_basic_user_file htpasswd;  # password file        try_files $uri =404;        Fastcgi_pass  Unix:/tmp/php-cgi.sock;        Fastcgi_index index.php;        Fastcgi_param script_filename $document _root$fastcgi_script_name;        Include Fastcgi_params;    }    Location/{        try_files $uri $uri//index.php? $uri & $args;    }    Location ~. *\. (gif|jpg|jpeg|png|bmp|swf) $ {        expires      30d;    }    Location ~. *\. (JS|CSS)? $ {        expires      30d;    }    Access_log  /home/wwwlogs/xhgui.access.log;    Error_log  /home/wwwlogs/xhgui.error.log;}

Open the HTTP Basic认证 need to generate a password file htpasswd . Assuming that you generate a tester user with a password of 123456 , execute the following command:

printf "tester:$ (OpenSSL passwd-crypt 123456) \ n" >>/usr/local/nginx/conf/htpasswd

After the build, remember to check the contents of the file, the format should resemble the following:

$cat/usr/local/nginx/conf/htpasswd Tester:1qe8kan82ioyo

Complete the configuration reboot, enter in the browser http://127.0.0.1:8888 , should be able to see the interface, but there is no data at this time.

3. Further optimization of the configuration

xhguiThe default is to collect by 1% , but if it is to troubleshoot the problem still want to be able to 100% acquisition will be more convenient. Enter the xhgui source directory, modify the config/config.default.php file, usually still according to 1% sampling rate sampling, to prevent data growth too fast, when you want to debug, the parameters added in the URL debug=1 .

In the config/config.default.php , find profiler.enable here, modify as follows:

' Profiler.enable ' = function () {    //URL contains debug=1 if    (!empty ($_get[' Debug ')}) {        return true;    } else {        //1% sample        return rand (1, +) = = =;    }},

If you do not delete the collected data, you will soon find that the mongo database becomes very large. Therefore, it is recommended to configure the mongo database to keep only the last 14 days of data.

#mongo > Use xhprof> db.results.ensureIndex ({"Meta.request_ts": 1}, {expireafterseconds:3600*24*14})

If you want to delete all manually, execute the following command:

$ mongo$ Use xhprof;$ db.dropdatabase ();

4. Application Configuration

To allow the application to implement the acquisition, you need to modify the corresponding nginx configuration file, add:

Fastcgi_param tideways_samplerate "100"; #是否采样取决于xhgui的随机数配置和这里的采样率配置, both must be satisfied at the same time, here simple set to 100, by Xhgui to control Fastcgi_param php_value "auto_prepend_file=/home/ Wwwroot/xhgui/external/header.php ";

The complete nginx sample configuration file is as follows:

server{    Listen, #根据实际情况修改    server_name test.dev; #根据实际情况修改    index index.html index.htm index.php;    Root  /home/wwwroot/test/web/;    Location ~ \.php    {        fastcgi_pass  unix:/tmp/php-cgi.sock;        fastcgi_index/index.php;        Fastcgi_param script_filename $document _root$fastcgi_script_name;        Fastcgi_param tideways_samplerate "100"; # Here is the focus        fastcgi_param php_value "auto_prepend_file=/home/wwwroot/xhgui/external/header.php"; # Here's the point        Include Fastcgi_params;    }    Try_files $uri $uri/@rewrite;    Location @rewrite {        rewrite ^/(. *) $/index.php?_url=/$1;    }    Location ~. *\. (gif|jpg|jpeg|png|bmp|swf) $ {        expires      30d;    }    Location ~. *\. (JS|CSS)? $ {        expires      30d;    }    Access_log  /home/wwwlogs/test.access.log;    Error_log  /home/wwwlogs/test.error.log;}

Finally, the interface to successfully configure and capture data
