Php engine optimization

6.1.php engine cache optimization

First of all, there are two main factors affecting the efficiency of php. First, libphp5.so needs to compile php source code into opcode tree (opcode); second, php needs to read and write with the database, and the concurrency ability of the database is very low.

So the php cache accelerator is to solve the above first reason, caching opcode content in order to prevent php from repeatedly compiling php code every time it requests, because on high-traffic websites, a large number of repeated compilations will reduce a lot of resources and time events, so the bottleneck here is that the repeated compilation of php not only affects the corresponding speed, but also increases the load on the server, in order to solve this problem. So the php accelerator was born.

To solve the problem between php and mysql, memcache is used, and the cache is set up between php and mysql, which effectively improves the concurrency of the database.

6.1.1 install 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 completion will display such a directory and record it.

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: just install one for xcache and eaccelerator

Php cache acceleration software category

Xcache,eaccelerator,Zend,apc

How to choose

Xcache,eaccelerator is advised to choose one of the two.

Xcache > eaccelerator

Reason:

A.xcache is faster and more efficient

B.xcache development is more active

Opcode cache acceleration software ↑

6.1.2 Database Cache memcache

Php bottleneck:

1. You need to parse the php code.

two。 Need to request the database, and the database concurrency is relatively low.

Solution: set up cache between php and database, memcached (client software)

Server 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 PHP to access the database, which provides a data access abstraction layer so that no matter what database is used, the query can be executed and the data can be obtained through a consistent function.

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/

6.1.4 install the image processing program and imagick extension module

Tar xf imagick-2.3.0.tgz

Eaccelerator.so imagick.so memcache.so pdo_mysql.so

6.1.5 configure the extension

Cp / application/php/lib/php.ini / application/php/lib/php.ini.bak

Vim / application/php/lib/php.ini

819 extension_dir = "/ application/php5.3.27/lib/php/extensions/no-debug-zts-20090626/"

Trailing append

1919;-

1920 extension = memcache.so

1921 extension = pdo_mysql.so

1922 extension = imagick.so

1923;-

Quick copy:

Extension = memcache.so

Extension = pdo_mysql.so

Extension = imagick.so

(1) configure the eaccelerator plug-in

1. Configure the eaccelerator cache directory

Mkdir-p / tmp/eaccelerator

Chown ett / tmp/eaccelerator-R

This directory can be stored in tmpfs memory file system, SSD solid state disk

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

Finally, through phpinfo (); check that all extensions have been installed

Wget http://blog.zyan.cc/soft/linux/webbench/webbench-1.5.tar.gz

Tar xf webbench-1.5.tar.gz

Cd webbench-1.5
