今天安装centos6.2，重装mysql+apache+php,
configure php的时候得到错误信息
./configure --prefix=/usr/local/php
--with-apxs=/usr/local/apache
--with-mysql=/usr/local/mysql configure: error: xml2-config not found. Please check your libxml2 installation.
没找到xml2-config这个文件，光盘里面有这两个文件 libxml2-2.6.23-1.2.i386.rpm libxml2-devel-2.6.23-1.2.i386.rpm
不过连网就方便多了，直接yum -y install libxml2 libxml2-devel
重新 ./configure -prefix=/usr/local/php
-with-apxs2=/usr/local/apache/bin/apxs
-with-mysql=/usr/local/mysql
Ok了。 make && make install 安装完成！
