GreenPlum的那些事《二》——GreenPlun启动报错

在配置好GreenPlum过程中,需要注意一下几点:

  1. 找好安装包
  2. 安装依赖,Gun版本需要注意
  3. 详细安装步骤参考Greenplum安装介绍

自己是电脑虚拟机安装的中间出现很多报错,度娘加经验解决。最后启动还是报错,发现是资源不足,所以关闭了mirror,减少了segment。然后启动还是报错:

查看日志没有找到什么原因,后台度娘发现了,原来是防火墙没有关闭。那么就来关闭防火墙:

/etc/init.d/iptables stop
[root@mpp03 ~]# /etc/init.d/iptables stop  
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]

在3台机器上都关闭防火墙操作,然后启动

gpstart

启动成功!

psql
[gpadmin@mpp01 ~]$ psql
psql (8.3.23)
Type "help" for help.

gp_sydb=# 

启动成功了,开始下面的学习吧
