PHP Engine Optimization

PHP Engine Optimization

6.1.php Engine Cache optimization

First, there are 2 main factors that affect PHP efficiency. One: libphp5.so need to compile PHP source code to become opcode tree (opcode); second: PHP needs to read and write to the database, the database concurrency is very low.

So the PHP cache accelerator is to solve the first reason above, the opcode content cache, the purpose is to prevent PHP every request to compile PHP code repeatedly, because on the high-traffic site, a large number of repeated compilation will be a lot of resources and time events, So the bottleneck here is that PHP's repeated compilation affects both the corresponding speed and the server load, in order to solve this problem, the PHP accelerator was born

Solve the problem between PHP and MySQL, using the memcache, between PHP and MySQL to set up a cache, effectively improve the number of database concurrency.

6.1.1 Installing the PHP engine cache accelerator

echo ' Export lc_all=c ' >>/etc/profile

Source/etc/profile

Echo $LC _all

Yum Install Perl-cpan

(1) Eaccelerator

Tar XF eaccelerator-0.9.6.tar.bz2

CD eaccelerator-0.9.6

/application/php/bin/phpize

./configure \

--enable-eaccelerator=shared \

--with-php-config=/application/php/bin/php-config

Make

Make install

Make install completes to display such a directory, recorded

ls/application/php5.3.27/lib/php/extensions/no-debug-zts-20090626/

(2) XCache

Http://xcache.lighttpd.net

/application/php/bin/phpize

./configure \

--enable-xcache \

--with-php-config=/application/php/bin/php-config

Make

Make install

Note: XCache and eaccelerator just put one on.

PHP Cache Accelerator Software types

Xcache,eaccelerator,zend,apc

How to choose

Recommended Xcache,eaccelerator Two Select a

Xcache>eaccelerator

Reason:

A.xcache faster and more efficient

B.xcache Development More Active

6.1.2 Database Cache Memcache

PHP Bottlenecks:

1. The PHP code itself needs to be parsed

2. Need to request database, database concurrency is relatively low

Solution: Set up cache between PHP and database, memcached (client software)

Service-Side memcached-1.4.3.tar.gz

Client memcache-2.2.5.tgz

Tar XF memcache-2.2.5.tgz

CD memcache-2.2.5

/application/php/bin/phpize

./configure--with-php-config=/application/php/bin/php-config

ls/application/php5.3.27/lib/php/extensions/no-debug-zts-20090626/

6.1.3pdo_mysql Expansion Module

The PDO extension defines a lightweight, consistent interface for the PHP Access database, which provides a data access abstraction layer so that queries and data can be executed through consistent functions, regardless of the database used

Tar XF pdo_mysql-1.0.2.tgz

CD pdo_mysql-1.0.2

/application/php/bin/phpize

./configure \

--with-php-config=/application/php/bin/php-config \

--with-pdo-mysql=/application/mysql

Make

Make install

ls/application/php5.3.27/lib/php/extensions/no-debug-zts-20090626/

(1) Configuring the Eaccelerator plugin

1. Configuring the Eaccelerator Cache directory

Mkdir-p/tmp/eaccelerator

Chown Ett/tmp/eaccelerator-r

This directory can be stored using the TMPFS memory file system, SSD

Cat >>/application/php/lib/php.ini <<eof

Eaccelerator.shm_size= "64"

Eaccelerator.cache_dir= "/tmp/eaccelerator"
