GREENPLUM 5.17 centos 6.10安裝步驟是什么

本篇內容介紹了“GREENPLUM 5.17 centos 6.10安裝步驟是什么”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！

安裝介質：
greenplum-db-5.17.0-rhel6-x86_64.zip

有二進制安裝包和RPM安裝包，我這里選擇二進制安裝包來安裝

機器規劃（一個主節點，三個數據節點）：

192.168.11.210 mdw
192.168.11.211 sdw1
192.168.11.212 sdw2
192.168.11.213 sdw3

1，禁用防火墻和selinux

service iptables stop
chkconfig iptables off
vi /etc/selinux/config
selinux=disabled

2，配置內核參數
配置內核參數文件：

vi /etc/sysctl.conf
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sem = 500 1024000 200 4096
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
vm.swappiness = 10
vm.dirty_expire_centisecs = 500
vm.dirty_writeback_centisecs = 100
vm.dirty_background_ratio = 0
vm.dirty_ratio=0
vm.dirty_background_bytes = 1610612736
vm.dirty_bytes = 4294967296

執行sysctl -p使內核參數生效

3，配置資源限制參數

vi  /etc/security/limits.conf
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

4，文件系統格式
文件系統格式推薦使用XFS

5，配置磁盤文件預讀參數
推薦配置為16384
獲取當前值：/sbin/blockdev --getra /dev/sda
設置新值：/sbin/blockdev --setra 16384 /dev/sda

6，配置磁盤I/O調度策略
推薦設置成deadline模式，有兩種設置方法
方法一：

echo deadline /sys/block/sda/queue/scheduler

重啟之后失效，可以把上面命令配置到環境變量或者rc.local里面使之啟動生效

方法二（永久）：
在grub.conf里面配置elevator=deadline：

vi /etc/grub.conf
kernel /vmlinuz-2.6.32-754.11.1.el6.x86_64 ro root=UUID=39773d5f-aa30-4e9c-aca4-b8f41a865397 elevator=deadline rd_NO_LUKS rd_NO_LVM.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet

7，禁用THP（透明大頁）
grub.conf里面添加transparent_hugepage=never：

vi /etc/grub.conf
kernel /vmlinuz-2.6.32-754.11.1.el6.x86_64 ro root=UUID=707d5027-2cc0-4111-9efc-bddc1cc4fe5d elevator=deadline rd_NO_LUKS rd_NO_LVM.UTF-8 rd_NO_MD SYSFONT=latarcyrheb-sun16 crashkernel=auto  KEYBOARDTYPE=pc KEYTABLE=us rd_NO_DM rhgb quiet transparent_hugepage=never

需要重啟生效

8，創建用戶和組

groupadd gpadmin
useradd gpadmin -g gpadmin
New password: <changeme>
Retype new password: <changeme>

9，安裝GPDB

unzip greenplum-db-5.17.0-rhel6-x86_64.zip 
./greenplum-db-5.17.0-rhel6-x86_64.bin

交互模式中需要接受license，設置安裝路徑等，本文安裝路徑為/home/gpadmin/greenplum

10，創建hostlist文件
創建兩個hostlist文件，列出各個節點的主機名（host列出所有機器主機名，seg_host僅列出segment主機名）

vi host
mdw
sdw1
sdw2
sdw3
vi seg_host
sdw1
sdw2
sdw3

11，配置各個節點互信

gpssh-exkeys -f  /home/gpadmin/greenplum/host

12，其它節點批量安裝GPDB

gpseginstall -f /home/gpadmin/greenplum/host

–確認其他節點安裝情況

gpssh -f /home/gpadmin/greenplum/host -e ls -l $GPHOME

13，創建數據存儲目錄
主節點創建數據目錄：

mkdir -p /home/gpadmin/gpdata/master

segment節點批量創建目錄

gpssh -f seg_host -e 'mkdir -p /home/gpadmin/gpdata/primary'
gpssh -f seg_host -e 'mkdir -p /home/gpadmin/gpdata/mirror'

由于本文是直接安裝在家目錄下面，不會涉及權限問題，如果安裝其它目錄下需要配置相應權限

14，配置NTP同步
略

15，配置初始化gpdb參數
復制初始化參數文件到gpdb安裝目錄

cp /home/gpadmin/greenplum/docs/cli_help/gpconfigs/gpinitsystem_config  /home/gpadmin/greenplum

修改gpdb初始化參數文件

vi gpinitsystem_config 
ARRAY_NAME="Greenplum Data Platform"
SEG_PREFIX=gpseg
PORT_BASE=6000
declare -a DATA_DIRECTORY=(/home/gpadmin/gpdata/primary  /home/gpadmin/gpdata/primary /home/gpadmin/gpdata/primary)
MASTER_HOSTNAME=mdw
MASTER_DIRECTORY=/home/gpadmin/gpdata/master
MASTER_PORT=5432
TRUSTED_SHELL=ssh
CHECK_POINT_SEGMENTS=8
ENCODING=UNICODE
MIRROR_PORT_BASE=7000
REPLICATION_PORT_BASE=8000
MIRROR_REPLICATION_PORT_BASE=9000
declare -a MIRROR_DATA_DIRECTORY=(/home/gpadmin/gpdata/mirror /home/gpadmin/gpdata/mirror /home/gpadmin/gpdata/mirror)
DATABASE_NAME=devin
MACHINE_LIST_FILE=/home/gpadmin/greenplum/seg_host

15，初始化gpdb

gpinitsystem -c gpinitsystem_config -h seg_host

其他常用參數
-s 配置standby master
-S spread mirror （默認grouped mirror模式）

16，檢查gpdb狀態

[gpadmin@mdw ~]$ gpstate
