今天在centos上编译php-5.5.15，
- cd php-5.5.15
- ./configure --prefix=/usr/local/php/ --with-config-file-path=/usr/local/php/etc/ --enable-fpm
返回错误：
- checking libxml2 install dir... no
- checking for xml2-config path...
- configure: error: xml2-config not found. Please check your libxml2 installation.
说是libxml2没装，但是用yum安装时发现已经安装了
- [root@localhost process]# yum install libxml2
- Loaded plugins: fastestmirror
- Loading mirror speeds from cached hostfile
- Setting up Install Process
- Package libxml2-2.7.6-14.el6_5.2.i686 already installed and latest version
- Nothing to do
查资料后发现原来还需要安装libxml2-devel，再次执行安装命令
再重新编译php，可以编译成功
编译php-5.5.15出错，xml2-config not found
