Greenplum的安装
Greenplum的安装
Geenplum是一款基于postgresql开发的mpp数据库，适合于数据仓库数据存储，是对hadoop无法有效处理结构化数据的一个很好的补充。
五年前曾经使用过greenplum，那时的版本还是3.6，现在已经更新到4.3.5了，有消息称今年将开源。
和以前的相比，安装方式也有了一些小变化，简记如下，如要更详细的说明，还是得看官方文档。
一、测试环境CentOS6.58台虚机Greenplum4.3.5二、环境准备1.修改系统参数
编辑/etc/sysctl.conf，以下是最小配置
kernel.shmmax=500000000
kernel.shmmni=4096
kernel.shmall=4000000000
kernel.sem=2505120001002048
kernel.sysrq=1
kernel.core_uses_pid=1
kernel.msgmnb=65536
kernel.msgmax=65536
kernel.msgmni=2048
net.ipv4.tcp_syncookies=1
net.ipv4.ip_forward=0
net.ipv4.conf.default.accept_source_route=0
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_max_syn_backlog=4096
net.ipv4.conf.all.arp_filter=1
net.ipv4.ip_local_port_range=102565535
dev_max_backlog=10000
net.core.rmem_max=2097152
net.core.wmem_max=2097152
vm.overcommit_memory=22.修改文件打开数等限制
编辑/etc/security/limits.conf
*softnofile65536
*hardnofile65536
*softnproc131072
*hardnproc131072编辑/etc/security/limits.d/90-nproc.conf
*softnofile65536
*hardnofile65536
*softnproc131072
*hardnproc1310723.修改scheduler
编辑scheduler，原先默认是cfq
echodeadline>/sys/block/vda/queue/scheduler
[root@bigdata03~]#more/sys/block/vda/queue/scheduler
noopanticipatory[deadline]cfq4.编辑/boot/grub/grub.conf
新增elevator=deadline
[root@bigdata03~]#more/boot/grub/grub.conf
...elevator=deadlinecrashkernel=auto...5.编辑设备块大小
[root@bigdata03~]#/sbin/blockdev--setra16384/dev/vda
[root@bigdata03~]#/sbin/blockdev--getra/dev/vda
163846.配置hosts文件
编辑/etc/hosts，添加，选中203作为master，其他为segment,偷懒没改，直接加了层别名
172.30.13.203bigdata03.rdchzmdw
172.30.13.204bigdata04.rdchzsdw1
172.30.13.205bigdata05.rdchzsdw2
172.30.13.206bigdata06.rdchzsdw3
172.30.13.207bigdata07.rdchzsdw4
172.30.13.208bigdata08.rdchzsdw5
172.30.13.209bigdata09.rdchzsdw6
172.30.13.210bigdata10.rdchzsdw77.分别创建各数据节点文件（一个含master，一个不含）
[root@bigdata03~]#more/tmp/hostfile_exkeys
mdw
sdw1
sdw2
sdw3
sdw4
sdw5
sdw6
sdw7[root@bigdata03data]#more/tmp/hostfile_segments
sdw1
sdw2
sdw3
sdw4
sdw5
sdw6
sdw7三、集群安装1.软件下载，上传、解压缩
下载地址：
https:
//network.pivotal.io/products/pivotal-gpdb
unzipgreenplum-db-4.3.5.2-build-1-RHEL5-x86_64.zip
/bin/bashgreenplum-db-4.3.5.2-build-1-RHEL5-x86_64.bin输入yes同意aggrement
输入安装路径，比如/usr/local/gpmaster最后安装完后，结果是这样的：
[root@bigdata03gpmaster]#ll

[INFO]completedsuccessfully实质就是master与各个节点创建了个ssh的信任关系，信任的key存放在/root/.ssh/authorized_keys里
--测试是否无需密码登陆，ok

[root@bigdata03~]#3.安装各个节点准备
首先把包传送到各个节点上，并解压缩以及创建用户，组等

5.时钟同步
[root@bigdata03~]#vi/etc/ntp.conf

【
在每个节点上都要安装ntp服务：
yuminstallntp
servicentpdstart
chkconfigntpdon
】
各个节点上的时钟以master为准，如04节点，需要改在第一行
