1.准备3台主机
本实例是部署实验环境，采用的是Citrix的虚拟化环境，分配了3台RHEL6.4的主机。
|------|------| |Master|创建模板后，额外添加20G一块磁盘/dev/xvdb，额外添加2块网卡eth1,eth2| |Standby|创建模板后，额外添加20G一块磁盘/dev/xvdb，额外添加2块网卡eth1,eth2| |Segment01|创建模板后，额外添加50G一块磁盘/dev/xvdb，额外添加2块网卡eth1,eth2|
网络规划
eth0(外部IP) | eth1 | eth2 | |
|---|---|---|---|
Master | 192.168.9.123 | 172.16.10.101 | 172.16.11.101 |
Standby | 192.168.9.124 | 172.16.10.102 | 172.16.11.102 |
Segment01 | 192.168.9.125(可选) | 172.16.10.1 | 172.16.11.1 |
实验环境资源有限暂时配置3个节点，后续可能会根据需求添加Segment02，Segment03...
修改主机名
将Master,Standby,Segment01的三台主机名分别设置为mdw, smdw, sdw1
主机名修改方法：
hostname 主机名
vi /etc/sysconfig/network 修改hostnameOptions：配置脚本，前期为了方便同步节点间的配置，可选。
export NODE_LIST='MDW SMDW SDW1'
vi /etc/hosts 临时配置
192.168.9.123 mdw
192.168.9.124 smdw
192.168.9.125 sdw1配置第一个节点到自身和其他机器的无密码登录
ssh-keygen -t rsa
ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.9.123
ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.9.124
ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.9.125
cluster_run_all_nodes "hostname ; date"磁盘规划
gp建议使用xfs文件系统，所有节点需要安装依赖包
# rpm -ivh xfsprogs-3.1.1-10.el6.x86_64.rpm
所有节点建立/data文件夹，用来挂载xfs的文件系统
mkdir /data
mkfs.xfs /dev/xvdb
[root@smdb Packages]# mkfs.xfs /dev/xvdb
meta-data=/dev/xvdb isize=256agcount=4, agsize=1310720 blks
= sectsz=512 attr=2, projid32bit=0
data = bsize=4096 blocks=5242880, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal log bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0vi /etc/fstab 添加下面一行
/dev/xvdb /data xfs rw,noatime,inode64,allocsize=16m1 12.关闭iptables和selinux
cluster_run_all_nodes "hostname; service iptables stop"
cluster_run_all_nodes "hostname; chkconfig iptables off"
cluster_run_all_nodes "hostname; chkconfig ip6tables off"
cluster_run_all_nodes "hostname; chkconfig libvirtd off"
cluster_run_all_nodes "hostname; setenforce 0"
cluster_run_all_nodes "hostname; sestatus"
vi /etc/selinux/config
cluster_copy_all_nodes /etc/selinux/config /etc/selinux/注：所有节点都要统一设定，我这里先配置了信任，用脚本实现的同步，如果没有配置，是需要每台依次设定的。
3.设定建议的系统参数
vi /etc/sysctl.conf
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sem = 250 512000 100 2048
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
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.conf.default.arp_filter = 1
net.core.netdev_max_backlog = 10000
vm.overcommit_memory = 2
kernel.msgmni = 2048
net.ipv4.ip_local_port_range = 1025 65535vi /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072同步到各个节点：
cluster_copy_all_nodes /etc/sysctl.conf /etc/sysctl.conf
cluster_copy_all_nodes /etc/security/limits.conf /etc/security/limits.conf磁盘预读参数及 deadline算法
在/etc/rc.d/rc.local 添加
blockdev --setra 16385 /dev/xvdb
echo deadline > /sys/block/xvdb/queue/scheduler
cluster_copy_all_nodes /etc/rc.d/rc.local /etc/rc.d/rc.local注：重启后 blockdev --getra /dev/xvdb 验证是否生效
验证所有节点的字符集
cluster_run_all_nodes "hostname; echo $LANG"重启所有节点，验证修改是否生效：
blockdev --getra /dev/xvdb
more /sys/block/xvdb/queue/scheduler
cluster_run_all_nodes "hostname; service iptables status"4.在Master上安装
mkdir -p /data/soft
上传greenplum-db-4.3.4.2-build-1-RHEL5-x86_64.zip到Master
**解压**
unzip greenplum-db-4.3.4.2-build-1-RHEL5-x86_64.zip
**安装**
/bin/bash greenplum-db-4.3.4.2-build-1-RHEL5-x86_64.bin5.在所有的节点上安装配置Greenplum
配置/etc/hosts
192.168.9.123 mdw
172.16.10.101 mdw-1
172.16.11.101 mdw-2
192.168.9.124 smdw
172.16.10.102 smdw-1
172.16.11.102 smdw-2
192.168.9.125 sdw1
172.16.10.1 sdw1-1
172.16.11.1 sdw1-2同步/etc/hosts配置
cluster_copy_all_nodes /etc/hosts /etc/hosts配置gp需要的互信
vi hostfile_exkeys 创建文件内容示例如下：
mdw
mdw-1
mdw-2
smdw
smdw-1
smdw-2
sdw1
sdw1-1
sdw1-2Option: 此时如果之前做了部分互信，可以清除之前为安装方便配置的ssh信任
rm -rf /root/.ssh/
# gpseginstall -f hostfile_exkeys -u gpadmin -p 123456
# su - gpadmin
$ source /usr/local/greenplum-db/greenplum_path.sh
$ cd /usr/local/greenplum-db
$ gpssh -f hostfile_exkeys -e ls -l $GPHOME互信此时应该是可用的，如果不可用，再次执行
gpssh -f hostfile_exkeys创建Data Storage Areas，root用户操作
# mkdir /data/master
# chown gpadmin /data/master/利用gpssh，在standby master上也创建数据目录
# source /usr/local/greenplum-db/greenplum_path.sh
# gpssh -h smdw -e 'mkdir /data/master'
# gpssh -h smdw -e 'chown gpadmin /data/master'在所有的segment节点上创建数据目录
先创建一个文件 hostfile_gpssh_segonly,包含所有segment节点的主机名
sdw1
创建目录
# source /usr/local/greenplum-db/greenplum_path.sh
# gpssh -f hostfile_gpssh_segonly -e 'mkdir /data/primary'
# gpssh -f hostfile_gpssh_segonly -e 'mkdir /data/mirror'
# gpssh -f hostfile_gpssh_segonly -e 'chown gpadmin /data/primary'
# gpssh -f hostfile_gpssh_segonly -e 'chown gpadmin /data/mirror'配置NTP
我这里没有配置NTP，生产环境建议配置。
验证OS设置
先建立一个hostfile_gpcheck文件
mdw
smdw
sdw1验证
$ source /usr/local/greenplum-db/greenplum_path.sh
$ gpcheck -f hostfile_gpcheck -m mdw -s smdw

$ mkdir -p /home/gpadmin/gpconfigs

$ cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/gpconfigs/gpinitsystem_config
$ cd /home/gpadmin/gpconfigs
修改

#declare -a MIRROR_DATA_DIRECTORY=(/data/mirror /data/mirror) 以后配置默认就是注释的运行初始化工具

解决方法：
1.所有节点安装ed
# rpm -ivh /tmp/ed-1.1-3.3.el6.x86_64.rpm
warning: /tmp/ed-1.1-3.3.el6.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID fd431d51: NOKEY
Preparing...########################################### [100%]
1:ed ########################################### [100%]
2.清除初始化系统的信息
/bin/bash /home/gpadmin/gpAdminLogs/backout_gpinitsystem_gpadmin_20150403_105721
3.重新初始化系统
gpinitsystem -c gpconfigs/gpinitsystem_config -h gpconfigs/hostfile_gpinitsystem -s smdw
吐槽下：明明依赖ed，官方安装文档中却没有提及..安装成功最后会输出类似下面的提示：
