第一章 文档概述
本文描述适用于Greenplum4.0以上版本的安装操作。所涉及到的操作系统相关参数调整，主要针对Redhat Linux操作系统。
第二章 安装介质
操作系统：CentOS release 6.5 (Final)。
Greenplum安装版本：greenplum-db-4.3.8.1-build-2-RHEL5-x86_64.zip
第三章 安装前准备
3.1、网络规划
建议在Greenplum数据库系统安装之前，把网络配置规划好
3.2、存储空间规划
首先，需要评估目标数据库数据所需要的空间容量。建议了解客户搭建Greenplum数据库的具体应用。
举例：估计数据库所需空间为U，数据库需要启用Mirror，磁盘阵列总可用空间为D（Raid之后）。空间规划服务和如下公式：
2 * U + U / 3 = D * 70%
磁盘空间D平均分配到各个Segment服务器上。
Master需要相应的空间。使用服务器内置硬盘的计算方式类似。
3.3、数据库实例规划
规划每个Segment服务器上建立的数据库实例的数量（instance数量），通常建议每2个CPU内核（core）对应一个数据库实例
第四章 操作系统设置
4.1 、设置主机名
修改各台主机的主机名称。一般建议的命名规则如下：
Master：mdw
Standby Master：smdw
Segment Host：sdw1、sdw2……sdwn
修改操作：
1、hostname mdw
2、修改 /etc/sysconfig/network 配置文件中的hostname4.2 、设置hosts解析(所有节点，Master和Segments)
通常Master和Standby Master主机都配置外部IP和内部IP。Segment主机可只配置内部IP。所有主机的hosts文件内容必须保持一致
127.0.0.1 mdw localhost localhost.localdomain localhost4 localhost4.localdomain4
192.168.1.201 mdw
192.168.1.202 sdw1
192.168.1.203 sdw24.3、安装依赖软件(所有节点，Master和Segments)
yum -y install ed rsync coreutils glib2 lrzsz sysstat e4fsprogs xfsprogs ntp readline-devel zlib zlib-devel openssl openssl-devel pam-devel libxml2-devel libxslt-devel python-devel tcl-devel gcc make smartmontools flex bison OpenIPMI-tools openldap openldap-devel logrotate python-py gcc-c++ apr-devel libcurl-devel bzip2-devel libyaml-devel openssh-clients【涉及机器】：所有服务器关闭防火墙
service iptables stop
chkconfig iptables off
service ip6tables stop
chkconfig ip6tables off4.4、配置NTP时间同步(所有节点)
使用root用户进行操作，涉及所有服务器。
Greenplum推荐使用NTP（Network Time Protocol）同步各台主机的时钟。建议设置一台独立的时钟服务器。例如时钟服务器IP为10.6.220.20
4.4.1、Master服务器配置与时钟服务器同步。
修改配置文件/etc/ntp.conf后，启动ntpd服务。举例：配置文件增加：
server 10.6.220.20启动NTP服务：
service ntpd start;chkconfig ntpd on#如果没有独立的时钟服务器，则应该以Master服务器做内部的时钟服务器，Master就可以不用修改ntp.conf配置文件，直接启动ntpd服务即可。
4.4.2、所有Segment服务器优先与Master服务器同步，其次与Standby Master服务器同步。
修改配置文件/etc/ntp.conf后，重启ntpd服务。配置文件增加：
server mdw prefer
server smdw启动服务：
service ntpd start;chkconfig ntpd on4.4.3、Standby Master服务器优先与Master服务器，其次与始终服务器同步。
修改配置文件/etc/ntp.conf后，重启ntpd服务。配置文件增加：
server mdw prefer
server 10.6.220.20启动服务：
service ntpd start;chkconfig ntpd on#如果没有独立的时钟服务器，第二行不用配置。
4.5 修改系统参数（Redhat）
【涉及机器】：所有服务器；使用root用户进行修改，重启后生效。
4.5.1、修改系统参数/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 655354.5.2、修改系统参数/etc/security/limits.conf
Linux PAM中 pam_limits.so 的配置文件
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 1310724.5.3、修改磁盘预读参数(所有节点，Master和Segments)
通过修改预读扇区数，可以有效磁盘的读性能，特别是顺序读，GPDB数据库要求最小磁盘扇区数为16384，建议设置为65535。
在参数文件/etc/rc.d/rc.local中增加；
blockdev --setra 65535 /dev/sd4.5.4、修改配置/boot/grub/menu.lst
Linux默认的I/O调度模式是CFQ，通常需要修改I/O调度策略为deadline，可以通过下面的命令查看I/O调度策略。
cat /sys/block/sda/queue/scheduler
#临时修改
echo deadline > /sys/block/sda/queue/scheduler如果永久修改I/O调度策略，则需要修改/boot/grub/menu.lst文件，在“kernel*”行后面增加elevator=deadline。
4.5.5、修改配置/etc/sysconfig/i18n
增加RC_LANG=en_US.UTF-8
4.6、启动IPMI服务
（IPMI（Intelligent Platform Management Interface）即智能平台管理接口是使硬件管理具备“智能化”的新一代通用接口标准。如果没有安装相关服务，建议安装）
service ipmi start;chkconfig ipmi on第五章 配置用户和数据目录
5.1、创建gpadmin用户(所有节点，Master和Segments)
[root@mdw ~]# groupadd -g 520 gpadmin
[root@mdw ~]# useradd -u 520 -g gpadmin gpadmin
[root@mdw ~]# passwd gpadmin
Changing password for user gpadmin.
New password:
BAD PASSWORD: is too simple
Retype new password:
passwd: all authentication tokens updated successfully.5.2、创建软件安装目录(所有节点，Master和Segments)
[root@mdw ~]# mkdir -p /gpdb/app
[root@mdw ~]# chown -R gpadmin:gpadmin /gpdb//gpdb目录为GPDB的BASE目录，/gpdb/app为GPDB的HOME目录。
第六章 安装Greenplum
6.1、上传并解压GPDB安装文件（仅Master节点）
[gpadmin@mdw gpdb]$ unzip greenplum-db-4.3.8.1-build-1-RHEL5-x86_64.zip

6.3、设置GPDB环境变量(仅Master节点)
安装完成后修改gpadmin用户home的~/.bashrc配置文件，增加
source /gpdb/app/greenplum_path.sh6.4、配置hostname文件（用于建立多机信任）
编辑节点信息文件(仅Master节点)。为了管理方便，在app目录下创建config文件夹，将节点信息文件存放在该目录下。需要创建两个文件，其中一个文件(hostlist)存放所有节点信息，seg_host文件只存放segment节点信息
[gpadmin@mdw app]$ mkdir config
[gpadmin@mdw app]$ cd config
[gpadmin@mdw config]$ cat hostlist
mdw
sdw1
sdw2
[gpadmin@mdw config]$ cat seg_host
sdw1
sdw26.5、打通所有节点直接的互信(仅Master节点)
GreenPlum数据库提供gpssh-exkeys工具来打开所有节点直接的互信关系，非常方便
[gpadmin@mdw config]$ gpssh-exkeys -f hostlist
[STEP 1 of 5] create local ID and authorize on local host
... /home/gpadmin/.ssh/id_rsa file exists ... key generation skipped
[STEP 2 of 5] keyscan all hosts and update known_hosts file
[STEP 3 of 5] authorize current user on remote hosts
... send to mdw
... 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 mdw
... finished key exchange with sdw1
... finished key exchange with sdw2
[INFO] completed successfully互信配置完成后，可以通过gpssh工具来验证互信是否成功配置，-e参数后面的是远程登录节点后执行的命令。通过gpssh工具可以在所有节点运行同一命令，非常方便(后续会用到)。
[gpadmin@mdw config]$ gpssh -f /gpdb/app/config/hostlist -e 'pwd'
[ mdw] pwd
[ mdw] /home/gpadmin
[sdw2] pwd
[sdw2] /home/gpadmin
[sdw1] pwd
[sdw1] /home/gpadmin6.6、Segment节点安装GreenPlum软件(仅Master节点)
通过gpseginstall命令安装segment软件，使用-u参数指定安装用户，-p参数指定安装用户的密码，这样将不再需要交互式输入密码。
[gpadmin@mdw config]$ gpseginstall -f hostlist -u gpadmin -p li0924

6.7、 Segment节点配置环境变量(所有Segment节点)
修改gpadmin用户home的~/.bashrc配置文件，增加
source /gpdb/app/greenplum_path.sh第七章 数据库的初始化
7.1、创建数据文件存放目录(所有节点)
[root@mdw ~]# mkdir -p /data/gpdata/master
[root@mdw ~]# chown -R gpadmin:gpadmin /data
[root@sdw1 ~]# mkdir -p /data/gpdata/primary
[root@sdw1 ~]# mkdir -p /data/gpdata/mirror
[root@sdw1 ~]# chown -R gpadmin:gpadmin /data本案例Master节点的数据文件存放在/data/gpdata/master目录,Segment节点的主数据文件存放在/data/gpdata/primary目录；镜像数据文件放在/data/gpdata/mirror目录
7.2、配置时间同步(所有节点)
本案例Master节点的服务器配置为NTP的服务端，Segment节点为NTP的客户端。Master节点使用root用户通过gpssh工具批量调用date命令对比各服务器的时间是否一致。
[gpadmin@mdw ~]$ gpssh -f /gpdb/app/config/hostlist
Note: command history unsupported on this machine ...
=> date
[sdw1] Wed Mar 28 17:51:36 CST 2018
[ mdw] Wed Mar 28 17:51:36 CST 2018
[sdw2] Wed Mar 28 17:51:36 CST 20187.3、系统检查(仅Master节点)
在初始化数据库之前，需要进行先决条件检查，主要检查磁盘I/O能力、网络带宽、内核参数、limit等条件是否满足GreenPlum数据库的要求。
参数配置检查
[gpadmin@mdw ~]$ gpcheck -f /gpdb/app/config/hostlist -m mdw

1 参数配置检查
gpcheck -f /gpdb/app/config/hostlist -m mdw -s smdw
核对并修改下你感应系统参数。
2 性能检查
2.1 网络性能检查
gpcheckperf -f /gpdb/app/config/hostlist -r N -d /tmp > checknetwork.out
2.2 磁盘性能检查
gpcheckperf -f /gpdb/app/config/hostlist -r ds -D -d /data/gpdata/primary -d /data/gpdata/mirror r > checkio.out
检查磁盘IO的目标目录是数据库的数据文件目录，测试工具会写入系统内存的两倍大小的数据量。7.4、创建GreenPlum数据库的参数文件(仅Master节点)
在$GPHOME/docs目录下，存在一些参数文件的模版，可以通过这些模版快速配置一些常用的参数文件。比如GreenPlum数据库的参数文件可以参考$GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config文件。
[gpadmin@mdw ~]$ cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config /gpdb/app/config/gpinitsystem_config配置参数文件gpinitsystem_config
[gpadmin@mdw config]$ cat gpinitsystem_config

接下来就可以使用gpinitsystem工具初始化数据库了，一些参数文件中没有设置的重要参数，在初始化数据库时会被使用默认值，可以在初始化之后根据需求及主机的配置进行设置。GreenPlum数据库的参数也分为静态参数和动态参数，静态参数需重启数据库才能生效，动态参数不需要重启数据库即可生效。
若需要standby master；可以-s 主机名即可；也可以后续使用gpinitsystem添加。这个后续文章讲解
