PHP Performance optimization Tool –XHPROF installation

PHP Performance Optimization Tool –XHPROF installation, here I first post the approximate steps:

1. Get Xhprof

2. Pre-compilation Pre-processing

3. Compiling the installation

4. Configure PHP.ini

5. View running Results

So let's start by installing the Xhprof tool:

1. Get Xhprof

You can enter the URL to download directly, or wget

1234	#wget http://pecl.php.net/get/xhprof-0.9.4.tgz #tar zxf xhprof-0.9.4.tgz

2. Pre-compilation Pre-processing

Before compiling the xhprof, do preprocessing, generate configure file;

12345

#cd xhprof-0.9.4 #cd Extension #phpize

Phpize doesn't have this command.

Used to extend the PHP extension module

Phpize is a content that belongs to Php-devel, so just run

Yum install Php-devel on the line.

Command: Yum install php-devel-y

Location:/usr/bin/phpize

3. Compiling the installation

#./configure–with-php-config=/usr/bin/php-config

#make && make Install

Installation Successful

4. Configure PHP.ini

Appended to the PHP configuration file, Xhprof extension, php.ini

12345

& nbsp [xhprof] extension=xhprof.so xhprof. Output_dir=/usr/< Span class= "crayon-v" >share/nginx/html/tmp/ xhprof

Note: If the 64-bit system needs to copy the xhprof.so file to the/lib64 directory

123	#cp/usr/lib64/php/modules/xhprof.so/lib64/

5. View running Results

Copy the instance to your Web directory for an example demo:

123	#cp-R examples xhprof_html xhprof_lib/usr/share/nginx/html/xhprof

A. Run the instance to see the effect, in the browser input

http://localhost/xhprof/examples/sample.php

B. Copy the above to run to the result (HTTP path), put in the browser again, fill in the previous corresponding domain name:

Http://localhost/xhprof/xhprof_html/index.php?run=5307089e3e0fe&source=xhprof_foos

To view the results, correct:

If the input browser has no data

This situation: Run #530707980ee18: Invalid run Id = 530707980ee18

Error Result:

May be your configuration permissions are insufficient, please give a permission, you can directly 777, and then rerun the walk after this step to see the effect.

Here Xhprof installation is over, start your performance optimization trip, with this tool will be more effective ~ ~
