前段时间，php 发布了5.3.4版本，修复了在 PHP-FPM SAPI 方面的一些bug,于是便打算跟进了.

先完全卸载掉之前的php 版本，下载最新的5.3.4源码包(http://www.php.net/distributions/php-5.3.4.tar.bz2)，解压，进入目录

我的configure:
[root@PowerPC php-5.3.4]# ./configure \
> --prefix=/usr/local/php \
> --exec-prefix=/usr/local \
> --sysconfdir=/etc/sysconfig/php \
> --localstatedir=/var/run \

检查依赖。报错了，

checking for MySQL support... yes
checking for specified location of the MySQL UNIX socket... /tmp/mysql.sock
configure: error: Cannot find libmysqlclient under /usr/local/mysql.
Note that the MySQL client library is not bundled anymore!

是mysql 安装目录不完整的问题，解决方案：
1.进入mysql 安装根目录
2.ln -s /usr/local/lib lib

make distclean ,再次检查依赖,通过了。

接下来，make 编译，时间会比较长。耐心等待……
编译完成后，make install 安装即可.

测试下php,

[root@PowerPC php-5.3.4]# php-fpm -v
PHP 5.3.4 (fpm-fcgi) (built: Dec 17 2010 09:23:44)
Copyright (c) 1997-2009 The PHP Group
Zend Engine v2.3.0, Copyright (c) 1998-2010 Zend Technologies

一切正常。再把之前备份的配置文件放到 /etc/sysconfig/php 下，启动php-fpm 就OK了.

至此，php 升级安装完成.
