安装php-5.2.5

--> 　　本文是一篇Red Hat Enterprise Linux AS release 3 环境下php安装笔记，目的在于为以后再次安装php作一个参考。
　　首先假设系统中已经安装好可以动态加载模块的apache服务器和mysql服务器，若尚未完成这两个服务的搭建，请先搭建这两个服务。

　　接下我们将安装php及将其于apache与mysql集成在一起。
　　准备软件包：
下载php源码包，首选国内的镜像：http://cn2.php.net/get/php-5.2.5.tar.bz2/from/this/mirror
解压软件包：
[root@centerws root]# tar jxvf php-5.2.5.tar.bz2
进入软件包目录阅读README和INSTALL文件：
[root@centerws root]# cd php-5.2.5
[root@centerws php-5.2.5]# less INSTALL

然后按照INSTALL文件中的方法进行安装：

运行configure脚本，黙认的安装目录为/usr/local，指定apxs的路径，并支持mysql：

 ./configure --with-apxs2=/home/httpd/bin/apxs --with-mysql

　　提示需安装2.6.11或以上版本的libxml2

configure: error: libxml2 version 2.6.11 or greater required.

libxml2的下载地址为：ftp://xmlsoft.org/libxml2/
下载版本2.6.30，速度稍稍有点慢
ftp://xmlsoft.org/libxml2/libxml2-2.6.30.tar.gz

解压后直接使用默认选项进行配置，没什么特别的操作:./configure;make;make install

然后继续安装php

./configure --with-apxs2=/home/httpd/bin/apxs --with-mysql
make
运行完了以后会提示运行make test
Build complete.
Don't forget to run 'make test'.

在测试时出了点错：
PASS CLI long options [sapi/cli/tests/015.phpt]

You may have found a problem in PHP.
We would like to send this report automatically to the
PHP QA team, to give us a better understanding of how
the test cases are doing. If you don't want to send it
immediately, you can choose "s" to save the report to
a file that you can send us later.
Do you want to send this report now? [Yns]: n

估计这两个错不会影响php的使用我就直安装了:

make install

拷贝配置文件：

[root@centerws php-5.2.5]# cp php.ini-dist  /usr/local/etc/php.ini

编缉httpd.conf文件（如果make install已将其添进去的话就不用改了）：

LoadModule php5_module modules/libphp5.so

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

启动httpd:

[root@centerws httpd]# ./bin/apachectl start

查看启动信息:

[root@centerws httpd]# cat logs/error_log
