centos7單機安裝Greenplum6 2 1

一、環境準備：

作業系統：centos-7-x86_64-minimal-1810.iso

資料庫：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系統後配置

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
配置主機網域名稱：/etc/hosts
192.168.111.111 master
關閉selinux：/etc/selinux/config
selinux=disabled

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

* soft nofile 65536

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

三、安裝資料庫

3.1 安裝命令：

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

或者yum -y install greenplum-db-6.2.1-rhel7-x86_64.rpm

useradd gpadmin

passwd gpadmin （密碼設為gpadmin123）
chown -r gpadmin /usr/local/greenplum*
chgrp -r gpadmin /usr/local/greenplum*

mkdir -p /data/gpdata/master

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

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
使環境變數生效：
source .bash_profile .bashrc

master

ssh-keygen

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

4.1 複製配置檔案

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

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

gpinitsystem -c /home/gpadmin/initgreenplum

psql -p 2345

修改資料庫密碼

alter role gpadmin with password '1234';

退出： \q

4.5  遠端連線配置

vim /data/gpdata/master/gpseg-1/postgresql.conf

修改：#listen_addresses = '*'，去#注釋

vim /data/gpdata/master/gpseg-1/pg_hba.conf

新增：host     all         gpadmin         0.0.0.0/0               md5

gpstop -u

其他啟停命令

gpstart #正常啟動

gpstop #正常關閉

gpstop -m fast #快速關閉

gpstop –r #重啟
