configure: error: xml2-config not found. Please check your libxml2 installation

安装PHP时的报错
checking libxml2 install dir… no
checking for xml2-config path…
configure: error: xml2-config not found. Please check your libxml2 installation.

检查是否安装了libxm包
[root@XKWB3403 php-5.3.8]# rpm -qa |grep libxml2
libxml2-2.6.26-2.1.12
libxml2-Python-2.6.26-2.1.12

重新安装libxml2和libxml2-devel包
yum install libxml2
yum install libxml2-devel -y

安装完之后查找xml2-config文件是否存在
[root@XKWB3403 php-5.3.8]# find / -name “xml2-config”
/usr/bin/xml2-config

如果存在的话重新安装php
[root@XKWB3403 php-5.3.8]# ./configure

之后再进行编译
make && make install
