標(biāo)簽（空格分隔）： GreenPlum
在配置好GreenPlum過程中，需要注意一下幾點(diǎn)：
- 找好安裝包
- 安裝依賴，Gun版本需要注意
- 詳細(xì)安裝步驟參考Greenplum安裝介紹
自己是電腦虛擬機(jī)安裝的中間出現(xiàn)很多報(bào)錯(cuò)，度娘加經(jīng)驗(yàn)解決。最后啟動(dòng)還是報(bào)錯(cuò)，發(fā)現(xiàn)是資源不足，所以關(guān)閉了mirror，減少了segment。然后啟動(dòng)還是報(bào)錯(cuò)：

查看日志沒有找到什么原因，后臺度娘發(fā)現(xiàn)了，原來是防火墻沒有關(guān)閉。那么就來關(guān)閉防火墻：
/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臺機(jī)器上都關(guān)閉防火墻操作，然后啟動(dòng)
