原因1
集群中有某个segment节点的防火墙没有关闭，直接关闭该节点的防火墙后原程序会继续执行的。
在某些情况下，防火墙会自动启动，所以会导致我们的GreenPlum安装失败，所以，可以做如下操作：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config setenforce 0 systemctl unmask firewalld.service systemctl start firewalld.service firewall-cmd --add-port=0-65535/tcp --permanent firewall-cmd --add-port=0-65535/udp --permanent firewall-cmd --reload firewall-cmd --list-ports systemctl stop firewalld.service systemctl disable firewalld.service systemctl mask firewalld.service systemctl status firewalld.service |
