centos7單機安裝Greenplum6.2.1

一、環境准備：

操作系統：CentOS-7-x86_64-Minimal-1810.iso

數據庫：greenplum-db-6.2.1-rhel7-x86_64.rpm

集群配置：1 master，1 primary segment ， 1個mirror segment

二、安裝linux系統后配置

2.1 基本配置

關閉防火牆：
　　systemctl stop firewalld
禁止防火牆開機啟動：
　　systemctl disable firewalld
修改主機名：
　　hostnamectl set-hostname master
配置主機域名：/etc/hosts
　　192.168.111.111 master
關閉selinux：/etc/selinux/config
　　SELINUX=disabled

2.2 修改內核：/etc/sysctl.conf

net.ipv4.ip_forward = 0 
net.ipv4.conf.default.accept_source_route = 0 
net.ipv4.tcp_syncookies = 1
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
net.core.somaxconn = 2048
kernel.sysrq = 1 
kernel.core_uses_pid = 1 
kernel.msgmni = 2048 
kernel.msgmax = 65536
kernel.msgmnb = 65536 
kernel.shmmni = 4096 
kernel.shmmax = 500000000 
kernel.shmall = 4000000000 
kernel.sem = 250 64000 100 512 
vm.overcommit_memory = 2

2.3 修改文件描述符文件：/etc/security/limits.conf

* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

 

三、安裝數據庫

3.1 安裝命令：

rpm -Uvh greenplum-db-6.2.1-rhel7-x86_64.rpm

3.2 創建gpadmin用戶並授權：

useradd gpadmin
passwd gpadmin
chown -R gpadmin /usr/local/greenplum*
chgrp -R gpadmin /usr/local/greenplum*

3.3 切換到gpadmin用戶，並創建數據目錄：

mkdir -p /data/gpdata/master
mkdir -p /data/gpdata/primary
mkdir -p /data/gpdata/mirror 

3.4 設置gpadmin用戶的環境變量：.bash_profile和.bashrc

source /usr/local/greenplum-db/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/data/gpdata/master/gpseg-1
export PGPORT=5432
export PGUSER=gpadmin
export PGDATABASE=gpdb

使環境變量生效：
source .bash_profile .bashrc

3.5 添加節點服務器文件（本例是單機，故只需要寫一個）：/home/gpadmin/seg_hosts

master

3.6 設置ssh免密：

ssh-keygen
ssh-copy-id master
gpssh-exkeys -f /home/gpadmin/seg_hosts

 

四、初始化數據庫

4.1 復制配置文件

cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/initGreenplum　

4.2 編輯配置文件 /home/gpadmin/gpinit ，修改下面內容：

declare -a DATA_DIRECTORY=(/data/gpdata/primary)
MASTER_HOSTNAME=master
MASTER_DIRECTORY=/data/gpdata/master
MASTER_PORT=5432
MIRROR_PORT_BASE=7000
DATABASE_NAME=gpdb
declare -a MIRROR_DATA_DIRECTORY=(/data/gpdata/mirror)
MACHINE_LIST_FILE=/home/gpadmin/seg_hosts

4.3 運行初始化命令

 gpinitsystem -c /home/gpadmin/initGreenplum
