1、centos6.9安装xampp（xampp-linux-x64-7.0.21-0-installer.run）后启动的时候，报错：

2、有人说少了glibc包，32/64的都安装了，然并卵

3、千辛万苦还是找到了答案：
vi /opt/lampp/lampp
找到export LD_ASSUME_KERNEL=2.2.5这一行，
并修改内容为export LD_ASSUME_KERNEL=2.8.0，保存退出就可以解决了。
当然修改为不低于2.6.32的其他值也可以，比如2.6.32
Linux 内核版本
4、找了下这个设置的资料解释,原来这个配置是为了旧操作系统的一些兼容性问题
LD_ASSUME_KERNEL
What is LD_ASSUME_KERNEL all about?
The environment variableLD_ASSUME_KERNELcan be set to a value that indicates the kernel OS API version an application is compatible with and is used by the Linux Dynamic Linker/Loader for determining what directory paths to use when loading the Standard C Library (GLIBC or libc.so.6). This is the primary mechanism for dealing with backwards compatibility for applications written for older Linux versions.
Here are the directory paths that are chosen based on the setting of LD_ASSUME_KERNEL:
/lib/libc.so.6
/lib/i686/libc.so.6
/lib/tls/libc.so.6
One of the primary distinguishers of features is the difference between the olderLinuxThreadsPOSIX threading model and the newer threading modelNPTL(Native POSIX Thread Library). This can be determined as follows on a Linux BASH command line;
