故障分析：

liblzma.so.5对应解压缩XZ，使用命令查看当前系统安装的XZ版本，发现只安装了XZ4,进一步检查，发现操作系统对应CnetOS 6，在查找数据源之后，返现CentOS 6目前只支持到XZ 4.999

[root@ngdpetl01 /root]#xz -V
xz (XZ Utils) 4.999.9beta
liblzma 4.999.9beta
[root@ngdpetl01 /root]#rpm -qa|grep xz-lzma-compat
xz-lzma-compat-4.999.9-0.3.beta.20091007git.el6.x86_64
[root@ngdpetl01 /root]#cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.5 (Santiago)

检查数据库安装要求后，发现当前Mogdb V2.0.1版本不支持CentOS 7以下版本

故障处理

更换系统版本后，问题消失

补充说明

可以获取其他系统CentOS 7版本的liblzma.so.5，放入到本机LD_LIBRARY_PATH对应目录下，重新执行命令进行尝试，查看是否可以正常安装。
