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
