GreenPlum 5.0的安装
基本环境：
| server | IP |
|---|---|
| MDW | 172.16.16.31 |
| SDW1 | 172.16.16.34 |
| SDW2 | 172.16.16.35 |
1：检查操作系统是否符合要求，以及系统设置。
我这里使用的系统是CentOS ,操作系统要求CentOS64-bit 6.x or 7.x，CentOS最好是7以上版本。 然后关闭selinux，iptables
cat /etc/selinux/config
SELINUX=disabled
查看状态：
[root@16-31 mail]# sestatus
SELinux status: disabled
关闭iptables
[root@16-31 ~]# chkconfig iptables off
[root@16-31 ~]# chkconfig --list |grep iptables
iptables 0:off 1:off 2:off 3:off 4:off 5:off 6:off
配置系统参数，官方给出了一些建议的配置：
vi /etc/sysctl.conf
然后修改
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
kernel.msgmni = 2048
net.ipv4.tcp_syncookies = 1
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 = 10000 65535
net.core.netdev_max_backlog = 10000
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.overcommit_memory = 2
第二个文件也有一些需要修改的地方
vi /etc/security/limits.conf
添加以下内容：
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072
修改IO调度算法：
echo deadline > /sys/block/sr0/queue/scheduler
然后重启机器。文件系统最好使用XFS。 禁用THP：
[root@16-31 ~]# grubby --update-kernel=ALL --args="transparent_hugepage=never"
[root@16-31 ~]# cat /sys/kernel/mm/*transparent_hugepage/enabled
[always] madvise never
[always] madvise never
2：安装Greenplum
我们下载的是5.0版本，使用二进制发行版安装，使用root用户登录，最好建立一个单独的用户进行安装。 所有节点创建用户
useradd gpadmin
先进行解压：
[root@16-31 sa]# unzip greenplum-db-5.0.0-rhel7-x86_64.zip
[root@16-31 gptest]# groupadd gpadmin
[root@16-31 gptest]# useradd -r -g gpadmin -s /bin/false gpadmin
开始安装：
[root@16-31 gptest]# /bin/bash greenplum-db-5.0.0-rhel7-x86_64.bin
安装过程会有提示：

********************************************************************************
安装以后的我们进去看一下具体的安装目录：
[root@16-31 greenplum-db-5.0.0]# ls
bin docs etc ext greenplum_path.sh include lib pxf sbin share
看看目录具体作用：
greenplum_path.sh：配置文件
bin目录：主要是一些工具，其中也包括pgsql等
docs目录：帮助文件和一些配置文件
etc:示例配置文件和一些工具的配置文件
ext：GP的一些绑定程序，我们看到现在只有一个python
include：GP的一些C的头文件
lib：库文件
sbin：内部脚本和程序
share ：共享文件夹
然后我们在另外两台机器上也执行相同脚本进行安装和部署或者使用gpseginstall进行安装。这里我们使用第二种方法 先修改host文件：
172.16.16.31 mdw
172.16.16.34 sdw1
172.16.16.35 sdw2
初始化一下环境变量，这里我们可以看到两个
[root@mdw greenplum-db-5.0.0]# source /home/greenplum-db-5.0.0/greenplum_path.sh
[root@mdw greenplum-db-5.0.0]# source /home/greenplum-db/greenplum_path.sh
两个文件是一模一样的选择任何都是一样的。然后创建一个文件：
[root@16-31 greenplum-db-5.0.0]# cat my_host_list_file
mdw
sdw1
sdw2
配置SSH的免密链接：
[gpadmin@mdw sa]$ gpssh-exkeys -f /home/gpdb/hostlist
[STEP 1 of 5] create local ID and authorize on local host [STEP 2 of 5] keyscan all hosts and update known_hosts file [STEP 3 of 5] authorize current user on remote hosts
... send to sdw1
***
*** Enter password for sdw1:
... send to sdw2 [STEP 4 of 5] determine common authentication file content [STEP 5 of 5] copy authentication files to all remote hosts
... finished key exchange with sdw1
... finished key exchange with sdw2 [INFO] completed successfully
在各个节点创建所必须的文件夹：
[gpadmin@mdw sa]$ gpssh -f /home/gpdb/seghostlist -e -v 'sudo mkdir -p /home/greenplum && sudo chown -R gpadmin /home/greenplum'
[WARN] Reference default values as $MASTER_DATA_DIRECTORY/gpssh.conf could not be found

下面开始安装：
[gpadmin@mdw home]$ gpseginstall -f /home/gpdb/hostlist -u gpadmin -p gpadmin

然后给这个账号暂时赋予管理员的权限：

安装完成以后我们检查一下安装：

接下来我们创建数据目录的空间：
[gpadmin@mdw home]$ cd greenplum/
[gpadmin@mdw greenplum]$ ls
greenplum-db greenplum-db-5.0.0
[gpadmin@mdw greenplum]$ source /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh
[gpadmin@mdw greenplum]$ gpssh -f /home/gpdb/hostlist -e 'mkdir -p /home/greenplum/data'
[sdw1] mkdir -p /home/greenplum/data
[sdw2] mkdir -p /home/greenplum/data
[ mdw] mkdir -p /home/greenplum/data
[gpadmin@mdw greenplum]$ gpssh -h mdw -e 'mkdir -p /home/greenplum/data/master'
[mdw] mkdir -p /home/greenplum/data/master
[gpadmin@mdw greenplum]$ gpssh -f /home/gpdb/seghostlist -e 'mkdir -p /home/greenplum/data/{primary,mirror}'
[sdw1] mkdir -p /home/greenplum/data/{primary,mirror}
[sdw2] mkdir -p /home/greenplum/data/{primary,mirror}
设置环境变量：
[gpadmin@sdw1 data]$ cat /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh >>/home/gpadmin/.bash_profile
[gpadmin@sdw1 data]$ source /home/gpadmin/.bash_profile

下面开始初始化数据库，首先我们创建配置文件： [gpadmin@mdw ~]$ cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/gpinitsystem_config
[gpadmin@mdw ~]$ ls
gpAdminLogs gpinitsystem_config
[gpadmin@mdw ~]$ chmod 775 gpinitsystem_config
[gpadmin@mdw ~]$ vi gpinitsystem_config
配置文件如下：
ARRAY_NAME="Greenplum Data Platform"
SEG_PREFIX=gpseg
PORT_BASE=40000
declare -a DATA_DIRECTORY=(/home/greenplum/data/primary /home/greenplum/data/primary)
MASTER_HOSTNAME=mdw
MASTER_DIRECTORY=/home/greenplum/data/master

CHECK_POINT_SEGMENTS=8
ENCODING=UNICODE
declare -a MIRROR_DATA_DIRECTORY=(/home/greenplum/data/mirror /home/greenplum/data/mirror)
MACHINE_LIST_FILE=/home/gpdb/seghostlist
下面就开始初始化数据库吧：

我们进入GP查看一下：
postgres=# select * from gp_segment_configuration;
dbid | content | role | preferred_role | mode | status | port | hostname | address | replication_port
------+---------+------+----------------+------+--------+-------+----------+---------+------------------

3 | 1 | p | p | r | u | 40001 | sdw1 | sdw1 | 54002

9 | 3 | m | m | r | u | 52002 | sdw1 | sdw1 | 53002
(9 rows)
添加成功。
最后我们还要贴一下mirror的配置文件：
[gpadmin@mdw greenplum-db]$ cat //home/gpadmin/gp_mirror_config
filespaceOrder=
mirror0=0:sdw2:52001:53001:54001:/home/greenplum/data/mirror/gp0
mirror1=1:sdw2:52002:53002:54002:/home/greenplum/data/mirror/gp1
mirror2=2:sdw1:52001:53001:54001:/home/greenplum/data/mirror/gp2
mirror3=3:sdw1:52002:53002:54002:/home/greenplum/data/mirror/gp3
