Greeplum安装过程(centos)
一、安装说明
1. 最少准备3台机器(或虚拟机)，单台机器设置多个网卡的方式也可以，不过我没有实际操作过；
2.3台centos在6.5以上，配置>1cpu，内存>=2G,磁盘空间>20G；
3.每台机器都有固定IP(方便设置)，分别命名为mdw,sdw01,sdw02。
二、调整系统参数
1.vim /etc/sysctl.conf #(在GreenPlum安装包里面有个README，有同样的内容)
[root@localhost ~]# cat /etc/sysctl.conf
# System default settings live in /usr/lib/sysctl.d/00-system.conf.
# To override those settings,enter new settings here,or in an /etc/sysctl.d/<name>.conf file
#
# For more information,see sysctl.conf(5) and sysctl.d(5).
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.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 = 1025 65535
net.core.netdev_max_backlog = 10000
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.overcommit_memory = 2
[root@localhost ~]#
2..在 /etc/security/limits.conf 后面添加
[root@localhost ~]# vi /etc/security/limits.conf
# /etc/security/limits.conf
#
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072
# End of file
3..关闭防火墙
[root@localhost ~]#chkconfig iptables off
[root@localhost ~]#service iptables stop
centos7 使用 firewalld 替代了iptables，注意命令的不同
(4).编辑 /boot/grub/grub.conf
[root@localhost ~]# vi /boot/grub/grub.conf
elevator=deadline
crashkernel=auto
三、安装Greenplum
1.在主节点上安装 greenplum
(1).下载 greenplum 软件，保存文件到/usr/local/wjc(我下载的版本是4.3.8.0)
https://network.pivotal.io/products/pivotal-gpdb#/releases/1624/file_groups/391
(2).新建用户 gpadmin
useradd gpadmin
[root@localhost ~]# useradd gpadmin
[root@localhost ~]# passwd #gpadmin
(3).解压greenplumxx.zip,并把解压后的.bin文件copy至/usr/local(官方推荐的安装路径,省却麻烦)
unzip xxxxxxx.zip
[root@localhost wjc]# pwd
/usr/local/wjc
[root@localhost wjc]# ls
greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.zip
[root@localhost wjc]# unzip greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.zip
Archive: greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.zip
inflating: README_INSTALL
inflating: greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.bin
[root@localhost wjc]# ls
greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.bin greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.zip README_INSTALL
[root@localhost wjc]#
[root@localhost wjc]# mv greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.bin /usr/local
[root@localhost wjc]# ls
greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.zip README_INSTALL
[root@localhost wjc]#
#执行下面的命令进行安装,可能要输入多个yes进行确定
[root@localhost wjc]#/bin/bash greenplum-db-4.3.8.0-build-1-RHEL5-x86_64.bin
#进行安装,出现下面的信息表示安装完成
...
...
(Selecting no will exit the installer)
********************************************************************************
yes
Extracting product to /usr/local/greenplum-db-4.3.8.0
********************************************************************************
Installation complete.
Greenplum Database is installed in /usr/local/greenplum-db-4.3.8.0
Pivotal Greenplum documentation is available
for download at http://docs.gopivotal.com/gpdb
********************************************************************************
[root@localhost local]#
#记住:默认安装路径在
/usr/local/greenplum-db-4.3.8.0
(4).修改Greenplum所有者
[root@localhost local]# chown -R gpadmin /usr/local/greenplum-db
[root@localhost local]# chgrp -R gpadmin /usr/local/greenplum-db
[root@localhost local]# chown -R gpadmin /usr/local/greenplum-db-*.*.*.*
[root@localhost local]# chgrp -R gpadmin /usr/local/greenplum-db-*.*.*.*
(5).配置环境变量
[root@localhost local]#vim /etc/profile
添加以下文件：
GPHOME=/usr/local/greenplum-db-4.3.8.0
PATH=$GPHOME/bin:$GPHOME/ext/python/bin:$PATH
export GPHOME
export PATH
[root@localhost local]# source /etc/profile
(6).设置Master主机上的数据目录,指定数据的存放位置,空间要足够
[root@localhost local]#mkdir /gpmaster
[root@localhost local]#chown -R gpadmin /gpmaster
[root@localhost local]#chgrp -R gpadmin /gpmaster
(7).使用gpadmin用户登录，修改gpadmin的环境变量，否则初始化GP的时候会找不到master的存储文件夹
修改 文件vim ~/.bashrc 添加下面信息，并刷新
MASTER_DATA_DIRECTORY=/gpmaster
export MASTER_DATA_DIRECTORY
-------------
[root@localhost local]# su - gpadmin
[gpadmin@localhost ~]$ ls
[gpadmin@localhost ~]$ vim ~/.bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
# User specific aliases and functions
MASTER_DATA_DIRECTORY=/gpmaster
export MASTER_DATA_DIRECTORY
[gpadmin@localhost ~]$ source ~/.bashrc
-------------------------
2.在各个区段服务器上安装GP
方法1:每台segment可以和master一样的安装方法
方法2:直接通过master主机对每台segment安装GP
(1).每台机器修改主机名
172.31.9.210 mdw
172.31.9.211sdw01
172.31.9.212sdw02
(2).master节点添加对应segmetn服务器的IP以及主机名
[root@localhost ~]# vim /etc/hosts
127.0.0.1 mdw
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
172.31.9.210 mdw
172.31.9.211sdw01
172.31.9.212sdw02
[gpadmin@mdw ~]$ touch all_hosts
[gpadmin@mdw ~]$ vim all_hosts
mdw
sdw01
sdw02
~
[gpadmin@mdw ~]$ touch all_segs
[gpadmin@mdw ~]$ vim all_segs
sdw01
sdw02
(4).gpadmin登录
su - gpadmin
source /usr/local/greenplum-db/greenplum_path.sh
gpssh-exkeys -f /home/gpadmin/all_hosts #输入root密码
[gpadmin@mdw ~]$ source /usr/local/greenplum-db/greenplum_path.sh
(5).生成无密码认证
[gpadmin@mdw ~]$ source /usr/local/greenplum-db/greenplum_path.sh
[gpadmin@mdw ~]$ gpssh-exkeys -f /home/gpadmin/all_hosts
[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 sdw01
***
*** Enter password for sdw01:
[ERROR sdw01] bad password
***
*** Enter password for sdw01:
[STEP 4 of 5] determine common authentication file content
[STEP 5 of 5] copy authentication files to all remote hosts
... finished key exchange with sdw01
[INFO] completed successfully
[gpadmin@mdw ~]$
(6).为每个区段建立gpadmin用户 #待验证 root登录
a.为每个区段建立gpadmin用户
gpssh -f /home/gpadmin/all_segs '/usr/sbin/useradd gpadmin -d /home/gpadmin -s bin/bash'
b.建立密码
gpssh -f /home/gpadmin/all_segs 'echo “gpadmin_password” | passwd gpadmin –1'
(7).复制greenplum软件到segment host
a.在主节点上创建安装GP的tar文件
cd /usr/local
gtar -cvf /home/gpadmin/gp.tar greenplum-db-*.*.*.*
b.用goscp命令将其安装到各个segment
source /usr/local/greenplum-db/greenplum_path.sh
gpscp -f /home/gpadmin/all_segs /home/gpadmin/gp.tar=:/usr/local
启动gpssh会话
gpssh -f /home/gpadmin/all_segs
在gpssh下解压
=>gtar
=> gtar --directory /usr/local -xvf /usr/local/gp.tar
建立gp当前版本目录连接:
=> ln -s /usr/local/greenplum-db-*.*.*.* /usr/local/greenplum-db
(8).修改目录所有者
=> chown -R gpadmin /usr/local/greenplum-db
=> chgrp -R gpadmin /usr/local/greenplum-db
=> chown -R gpadmin /usr/local/greenplum-db-*.*.*.*
=> chgrp -R gpadmin /usr/local/greenplum-db-*.*.*.*
(9).建立segment节点上的存储区
=>
=>mkdir /home/gpadmin/primary #主文件
=>mkdir /home/gpadmin/mirror #镜像文件
修改权限和所有者(同步骤(8))
=> chown -R gpadmin /home/gpadmin/primary
=> chgrp -R gpadmin /home/gpadmin/primary
=> chown -R gpadmin /home/gpadmin/mirror
=> chgrp -R gpadmin /home/gpadmin/mirror
------#######--------
[gpadmin@mdw ~]$ gpssh -f /home/gpadmin/all_segs
Note: command history unsupported on this machine ...
=> ln -s /usr/local/greenplum-db-*.*.*.* /usr/local/greenplum-db
[sdw01]
=> chown -R gpadmin /usr/local/greenplum-db
[sdw01]
=> chgrp -R gpadmin /usr/local/greenplum-db
[sdw01]
=> chown -R gpadmin /usr/local/greenplum-db-*.*.*.*
[sdw01]
=> chgrp -R gpadmin /usr/local/greenplum-db-*.*.*.*
[sdw01]
=> mkdir /home/gpadmin/primary
[sdw01]
=> mkdir /home/gpadmin/mirror
[sdw01]
=> chown -R gpadmin /home/gpadmin/primary
[sdw01]
=> chgrp -R gpadmin /home/gpadmin/primary
[sdw01]
=> chown -R gpadmin /home/gpadmin/mirror
[sdw01]
=> chgrp -R gpadmin /home/gpadmin/mirror
[sdw01]
=> exit
[gpadmin@mdw ~]$
(10).退出gpssh交互模式
=>exit
3.初始化GP
(1).同步时钟
[gpadmin@mdw ~]$gpssh -f /home/gpadmin/all_hosts -v data
[gpadmin@mdw ~]$gpssh -f /home/gpadmin/all_hosts -v ntpd
(2).系统检测
[gpadmin@mdw ~]$gpcheckos -f /home/gpadmin/all_hosts
(3).将/usr/local/greenplum-db-4.3.8.0/docs/cli_help/gpconfigs/gpinitsystem_config 复制到/home/gpadmin/gpconfigs目录（没有就新建个）下然后编辑：
cd /home/gpadmin
mkdir gpconfigs
cp /usr/local/greenplum-db-4.3.8.0/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/gpconfigs
vi gpinitsystem_config
[gpadmin@mdw ~]$ cd /home/gpadmin
[gpadmin@mdw ~]$ mkdir gpconfigs
[gpadmin@mdw ~]$ cp /usr/local/greenplum-db-4.3.8.0/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/gpconfigs
[gpadmin@mdw ~]$ ls gpconfigs
gpinitsystem_config
[gpadmin@mdw ~]$

(4).初始化数据库：

[gpadmin@mdw gpconfigs]$gpinitsystem -c /home/gpadmin/gpconfigs/gpinitsystem_config

psql (8.2.15)
Type "help" for help.
