编译php包：php-5.4.26.tar.bz2
解压php-5.4.26.tar.bz2后，进入php解压目录：
./configure --prefix=/usr/local/php --enable-fpm --enable-debug --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --enable-mbstring --with-curl --with-mysql=/usr/local/mysql/ --with-mysqli=/usr/local/mysql/bin/mysql_config --with-config-file-path=/usr/local/php/etc
运行后遇到的问题：
error 1
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.
（看提示就明白 是一个lib库没装 先用 yum search 名字 看是否能搜到名字 ，找到名字后 把软件包 开发包装上）
解决办法
yum install libxml2-devel.x86_64 -y
error 2
