CentOS 5.5上编译安装 PHP 5.3.6

CentOS 5.6一直没发布，CentOS 5.5的PHP5.1.6不支持json/hash，因为正研究Postfix+Dovecot邮件系统，webmail采用的 RoundCube 新版本（v0.5）要求PHP版本不小于5.2.1，于是决定编译安装最新版PHP。PHP前几天被入侵据说v5.3.6代码被污染，不过用来做研究测试应该没问题。

先卸载本机已经安装的PHP包，这些软件包将会通过接下来的编译方式安装，安装必须软件

# yum remove php php-common php-devel php-cli php-mbstring php-mhash

php-mysql php-pgsql php-ldap php-imap php-pear php-pdo php-gd

如果不需要pgsql数据库则可以去掉postgresql相关包

# yum install httpd-devel libtool-ltdl libtool-ltdl-devel openssl-devel

libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel

libc-client libc-client-devel gd gd-devel libmcrypt libmcrypt-devel

sqlite sqlite-devel mysql-devel libicu libicu-devel pcre-devel

postgresql84 postgresql84-libs postgresql84-server postgresql84-devel

如果不安装 libtool-ltdl-devel编译时会出错，所以要么安装这个包要么执行以下命令：

# cd /usr/lib

# ln -s libltdl.so.3.1.4 libltdl.so

libicu是 --enable-intl Enable internationalization support 需要的包下载源代码到 src 目录并解压：
# cd /usr/local/src
# wget http://cn.php.net/get/php-5.3.6.tar.bz2/from/this/mirror
# tar -xjf php-5.3.6.tar.bz2

配置安装参数
./configure --build=i686-RedHat-linux-gnu --host=i686-redhat-linux-gnu
--target=i686-RedHat-linux-gnu --with-apxs2=/usr/sbin/apxs
--prefix=/usr/local --exec-prefix=/usr/local --with-exec-dir=/usr/local/bin
--sysconfdir=/etc --libdir=/usr/local/lib/php --with-libdir=lib

--mandir=/usr/local/share/man --infodir=/usr/local/share/info

--with-pcre-regex=/usr

--with-pdo-mysql --with-mysql --with-mysql-sock=/var/lib/mysql/mysql.sock
--with-pgsql --with-pdo-pgsql --with-sqlite=shared --with-pdo-sqlite=shared

--with-pear --with-gd --enable-gd-native-ttf --enable-calendar=shared
--enable-exif --enable-ftp --enable-sockets --enable-bcmath
--enable-sysvsem --enable-sysvshm --enable-sysvmsg --enable-intl
--enable-mbstring --enable-zend-multibyte --enable-zip
--without-unixODBC --disable-tokenizer

非RHEL/CentOS系统可以省略 --build，--host，--target 参数，程序会自动判断（LINUX一般为i686-pc-linux-gnu）。如果没安装pgsql或者不需要pgsql的支持可以删除相关参数（共2个）。 bz2, calendar, curl, mcrypt, pdo_sqlite, sqlite 这些模块采用动态编译，可采用下面将会提到的方法加载。编译并安装
# make && make install
安装结果摘要，里面有几个主要的安装路径变量

libtool: install: warning: remember to run `libtool --finish /usr/local/src/php-5.3.6/libs
[activating module `php5 in /etc/httpd/conf/httpd.conf]

Installing PHP CLI binary: /usr/local/bin/
Installing PHP CLI man page: /usr/local/share/man/man1/
Installing shared extensions: /usr/local/lib/php/20090626/

貌似要运行一次libtool --finish ....，不过我运行后也没什么奇特效果~

更新httpd配置文件以便apache能解析php文件

# vim /etc/httpd/conf/httpd.conf

添加以下内容

AddType application/x-httpd-php .php

AddType application/x-httpd-php-source .phps

如果在卸载原有PHP之前没备份php.ini文件，那么可以从PHP编译目录中把 php.ini-production 拷贝到 /etc目录下并改名为 php.ini

# mv /usr/local/src/php-5.3.6/php.ini-production /etc/php.ini

添加或者更新相关设置，比如：
extension_dir = "/usr/local/lib/php/20090626"
# 以下六个模块可根据需要添加
extension = bz2.so
extension = calendar.so
extension = curl.so
extension = mcrypt.so
extension = pdo_sqlite.so
extension = sqlite.so

max_execution_time = 30
max_input_time = 60
memory_limit = 128M
variables_order = "EGPCS"
register_globals = Off
register_long_arrays = Off
post_max_size = 30M
upload_max_filesize = 30M
mbstring.internal_encoding = UTF-8
date.timezone = Asia/Chongqing

测试结果。在 /var/www/html 下面新建一个文件 phpinfo.php ，里面包含内容

Php代码
<?php
phpinfo();
?>

重启apache服务
# service httpd restart
然后在浏览器打开 http://192.168.0.1/phpinfo.php 文件查看php配置状况，这里ip地址为服务器地址
