初始化greenplum时无法启动段实例数据库sdwXX

Question

我在初始化Greenplum时遇到一个问题，所以无法成功安装Greenplum。 我用网桥模式在虚拟机上成功安装了Greenplum，在初始化过程中也遇到了一个问题，说它不能在网段之间复制文件（如sdw1和sdw2），我从网上找到了设置DNS的解决方案，然后我成功地安装了Greenplum。 现在我在云服务器上安装Greenplum的方式和VMs一样，CentOS有默认的DNS，但是我试了很多次都没有成功安装，我觉得问题是‘段实例数据库sdwXX启动失败’，但我不知道是什么原因造成的。请帮帮我，谢谢。 日志如下：

所以我看到了/home/gpadmin/gpAdminLogs/gpinitsystem_20160717.log，部分内容如下：

Answer 1

检查所有环境变量的设置是否正确。这些部分应该有这些

export LD_LIBRARY_PATH=$LD_LIBRARY_路径：/usr/local/lib export LIBRARY_PATH=$LD_LIBRARY_路径 ~

另外，请检查是否在gpinitsystem之前执行了gpsegsinstall
