-- With-ttf enables freetype1. *.

-- With-xsl: supports opening XSLT files, extends the libXML2 library, and requires libxslt software.

-- With-gettext: Open the gnu gettext support, which is used by the encoding library.

-- With-pear support for opening the pear command, which is used for PHP Extension

-- Enable-calendar to enable the calendar Extension function

-- Enable-mbstring multi-byte, string supported

-- Enable-bcmath: enable image size adjustment. This module is used for zabbix monitoring.

-- With-mime-magic =/usr/share/file/magic. mime magic header file location

Parameters used for CGI Installation

-- Enable-fpm

This parameter is available only after the PHP-fpm patch is installed. The startup program installed in CGI Mode

-- Enable-fastCGI

Supports fastcgi to start PHP

-- Enable-force-CGI-redirect

Redirect to start PHP

-- With-ncurses

Dynamic library supporting ncurses screen rendering and graphic interaction based on text Terminals

-- Enable-pcntl freeTDS is required. It may be used only when mssql is linked.

Extensions of mhash and mcrypt Algorithms

-- With-mcrypt Algorithm

-- With-mhash Algorithm

The above function library needs to be installed

-- With-gmp should support a Specification

-- Enable-inline-optimization thread

-- With-openssl support, used for encrypted transmission

-- Enable-mbregex

-- Enable-wddx

-- Enable-shmop

-- Enable-soap

After -- with-apxs2 =/usr/local/apache/bin/apxs is specified, do not activate -- enable-fpm and -- enable-fastCGI, apxs loads php in the PHP module mode.

After Mysql compiles the Mysql development library, you do not need to specify the mysql path.

PHP compilation has a basic dependency relationship. To compile PHP, you must first install XML extensions, because the php5 core enables XML support by default. For other basic libraries, you must:

GD-> zlib, Png, and Jpg. If you need to support others, you still need to compile the extension library based on the actual situation. The ttf Library requires freetype library support.

-- Enable-magic-quotes is an extremely unrecommended parameter. Of course, if you need PHP to do the underlying work for you, it does not solve the problem thoroughly.

-- With-openssl: The openssl library is required.

Mysqli is a MySQL driver provided by the MySQL team. It has many practical functions and typical features. However, he is not the best choice for MySQL on the PHP platform. PDO has been proven to be a simple, highly concurrent standard interface that is easy to create and recycle. However, PDO also experienced memory overflow problems before 5.3. After 5.3, when reading Oracle LOB resources, if the memory is not limited, the memory will still overflow.

It is not recommended for product models such as pear, shmop, and ftp. What they want to do is use C/C ++, Java, or other scripting languages, there are good and fast options, and there is no need to limit to using PHP for implementation. Unfamiliar class libraries and infrequently used libraries are not recommended. Magic-quote, session. auto_start, PHP server information, and PHP error information should be closed immediately after compilation to avoid exposing server information.

For the Web Server mode corresponding to PHP, Module, fastcgi, and fpm only need one type. The Server is not your test field. Fastcgi can select Nginx and lighttpd. In fact, Nginx uses lighttpd's spwan-fcgi for fcgi process management. Fpm uses PHP to manage multiple processes, which is similar to a backend proxy. Regardless of the mode, process and thread optimization should be performed on the production server, and sufficient stress tests should be performed to find the best combination of process numbers.

It is also important to choose a PHP OPCode cache extension. At the core of linux 2.6 and fcgi, xcache has good practical experience. When the number of concurrent threads increases, severe performance attenuation.

If you really want to try it out, you 'd rather compile several more PHP versions than compile various extensions for one version of PHP to adapt to various environments, which will put yourself in a dilemma.

Compile the extension Library:

/Usr/local/php/bin/phpize

./Configure -- with-php-config =/usr/local/php/bin/php-config

Make

Make install

Ln-s ../ext/sockets/modules/sockets. so sockets. so establishes a soft connection to the so dynamic link library.

Compile php:

. /Configure -- prefix =/usr/local/php -- with-curl =/usr/local/curl -- enable-mbstring -- enable-shmop -- enable-sysvsem -- enable-sysvshm -- enable -sysvmsg -- with-mysql =/usr/local/mysql -- with-mysqli =/usr/bin/mysql_config -- enable-sockets

Make

Make install

Which php ensures that php is the latest and soft links can be established.
