Implementation of PHP cache optimization with Memcached,xcache

We know that Eaccelerator is a free open source PHP accelerator, optimized and dynamic content cache, can improve the PHP script cache performance, and to optimize the script, so that your PHP program code execution efficiency can increase 1-10 times, today to teach you PHP optimization cache method.

2. Caching principle

When a user requests a PHP program, the PHP engine parses the program and compiles it into a specific opcode (opcode), which is a binary-formatted executable code. The opcode is then executed and discarded by the PHP engine. The opcode cache saves this compiled opcode and reuses it the next time the page is called, saving a lot of time to repeat the compilation, saving resources, and optimizing performance.
3. Installing Eaccelerator

Adjust Character Set

#echo ' lc_all=c ' >>/etc/profile#source/etc/profile[root@~] #tar jxf eaccelerator-0.9.6.tar.bz2[root@~] #cd Eaccelerator-0.9.6[root@~]#/usr/local/php/bin/phpizephpize is used to extend the PHP module, through the phpize can build PHP plug-in module [root@~]#./configure --enable-eaccelerator=shared \--with-php-config=/usr/local/php-5.3.27/bin/php-config[root@~] #make && make install[root@~]# ls/usr/local/php-5.3.27/lib/php/extensions/no-debug-zts-20090626/eaccelerator.so

4. Configure PHP Load Eaccelerator

Create a cache directory

Mkdir/tmp/eaccelerator #可目录可以用tmpfs内存文件系统来存储, SSD solid-state Drive

Chown-r Www.www/tmp/eaccelerator

In php.ini, add the following:

Eaccelerator Cache config by Zhang dejin 2017-12-1[eaccelerator]extension = eaccelerator.soeaccelerator.shm_size= "64" Eaccelerator.cache_dir= "/tmp/eaccelerator" eaccelerator.enable= "1" eaccelerator.optimizer= "1" eaccelerator.chech_ Mtime= "1" eaccelerator.debug= "0" eaccelerator.filter= "" eaccelerator.shm_max= "0" eaccelerator.shm_ttl= "3600" eaccelerator.shm_prune_perid= "3600" eaccelerator.shm_only= "0" eaccelerator.compress= "1" eaccelerator.compress_ Level= "9"--end config test: [root@lnmp nginx]#/usr/local/php-5.3.27/bin/php-vphp 5.3.27 (CLI) (Built:nov 30 2017 05:35:00) Copyright (c) 1997-2013 the PHP groupzend Engine v2.3.0, Copyright (c) 1998-2013 Zend technologieswith eaccelerator v0.9.6 , Copyright (c) 2004-2010 eaccelerator, by Eaccelerat

Configuration complete

Restart httpd or php-fpm in effect

5. Version Selection

PHP5.3.XX Available eaccelerator-0.9.6 version
PHP5.2.XX Available eaccelerator-0.9.5.2 version

2) Xcache

1 Introduction

XCache is a fast and stable PHP opcode cache. Good testing and stable operation on large-flow/high-load production machines. Tested and supported on (on Linux) the latest release versions of all current PHP branches, such as Php_4_3 php_4_4 php_5_0 php_5_1 php_5_2 HEAD (6.x), and support for thread safety/windows. Better than a similar opcode cache, such as the ability to quickly follow up on PHP versions. XCache Project by MOo leader, he is also one of the development members of LIGHTTPD. LIGHTTPD is one of the fastest Web server applications and goes beyond Apache and many other Web servers. XCache efforts to achieve a similar effect. 2. Installation

Tar jxf xcache-1.3.2.tar.bz2cd xcache-1.3.2/usr/local/php-5.3.27/bin/phpize./configure--enable-xcache-- With-php-config=/usr/local/php-5.3.27/bin/php-configmake && make installls/usr/local/php-5.3.27/lib/php/ extensions/no-debug-zts-20090626/

3. Configure PHP Load XCache

cd/usr/local/php/lib/

Add notes

echo >> php.iniecho "XCache config by Zhangdejin 2017-12-1"

Modify Xcache-1.3.2/xcache.ini, use sed command to modify
Note Third line

Zend_extension =/usr/local/lib/php/extensions/non-debug-non-zts-xxx/xcache.so

Note Line Sixth

Zend_extension_ts = C:/php/extensions/php_xcache.dll

Enable line Eighth

; extension = xcache.so

The remaining parameters are self-tuning based on the server configuration
Then join the php.ini

Cat/home/king/xcache-1.3.2/xcache.ini >> php.ini

3) Memcache client, Pdo_mysql,imagick Extension Library

1. Introduction

Memcache is a high-performance distributed memory object caching system that maintains a unified, huge hash table in memory that can be used to store data in various formats, including images, video files, and database retrieval results, simply by calling data into memory and then reading from memory. Thus greatly improving the reading speed

The PDO extension defines a lightweight, consistent interface for the PHP Access database, which provides a data access abstraction layer so that data can be obtained through a consistent function execution query, regardless of the database used

ImageMagick is a powerful, stable and free working set and development package, with images over 89 formats in the format of resizing, rotating, sharpening, subtractive processing, and now its main focus on performance, reducing bugs as well as providing stable APIs and Abi on
