greenplum單機(jī)安裝

環(huán)境：

服務(wù)器版本：centos 6.5

數(shù)據(jù)庫版本：greenplum-db-4.2.8.5-build-1-RHEL5-x86_64.zip

1.創(chuàng)建用戶和組gpadmin

groupadd -g  3030 gpadmin

useradd -u 3030 gpadmin -g gpadmin -d /home/gpadmin

passwd gpadmin

配置內(nèi)核參數(shù)，添加如下內(nèi)容：

vi /etc/sysctl.conf

#By greenplum

net.ipv4.ip_forward = 0

net.ipv4.conf.default.accept_source_route = 0

kernel.sysrq = 1

kernel.core_uses_pid = 1

net.ipv4.tcp_syncookies = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.sem = 250 64000 100 512

kernel.shmmax = 500000000

kernel.shmmni = 4096

kernel.shmall = 4000000000

kernel.sem = 250 64000 100 512

net.ipv4.tcp_tw_recycle=1

net.ipv4.tcp_max_syn_backlog=4096

net.core.netdev_max_backlog=10000

vm.overcommit_memory=2

net.ipv4.conf.all.arp_filter = 1

以上參數(shù)可以根據(jù)自己系統(tǒng)配置做適當(dāng)修改

手工執(zhí)行命令，讓參數(shù)生效

[root@gpmaster ~]# sysctl -p

在limits.conf文件中添加如下配置

[root@gpmaster ~]# vi /etc/security/limits.conf

# End of file

* soft nofile 65536

* hard nofile 65536

* soft nproc 131072

* hard nproc 131072

配置用戶ssh用戶無密碼登錄，單機(jī)也得配置

[root@gpmaster ~]# su - gpadmin

[gpadmin@gpmaster ~]$ mkdir ~/.ssh

[gpadmin@gpmaster ~]$ chmod 700 ~/.ssh

[gpadmin@gpmaster ~]$ cd .ssh/

[gpadmin@gpmaster .ssh]$ ssh-keygen -t rsa

[gpadmin@gpmaster .ssh]$ ssh gpmaster cat /home/gpadmin/.ssh/id_rsa.pub >>authorized_keys

[gpadmin@gpmaster .ssh]$chmod 600 authorized_keys

[gpadmin@gpmaster .ssh]$ ssh gpmaster date

2.安裝GP軟件

[root@gpmaster ~]# unzip greenplum-db-4.2.8.5-build-1-RHEL5-x86_64.zip

[root@gpmaster ~]# ./greenplum-db-4.2.8.5-build-1-RHEL5-x86_64.bin

創(chuàng)建instance需要的目錄

[root@gpmaster ~]# mkdir -p /app/master

[root@gpmaster ~]# mkdir -p /app/data/gp1

[root@gpmaster ~]# mkdir -p /app/data/gp2

[root@gpmaster ~]# mkdir -p /app/data/gp3

[root@gpmaster ~]# mkdir -p /app/data/gp4

修改目錄屬主：

[root@gpmaster ~]# chown -R gpadmin:gpadmin /usr/local/greenplum-db*

[root@gpmaster ~]# chown -R gpadmin:gpadmin /app/master

[root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp1

[root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp2

[root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp3

[root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp4

修改gpadmin用戶環(huán)境配置：

[root@gpmaster ~]# su - gpadmin

[gpadmin@gpmaster ~]$ vi .bash_profile

source /usr/local/greenplum-db/greenplum_path.sh

export MASTER_DATA_DIRECTORY=/app/master/gpseg-1

export PGPORT=5432

export PGUSER=gpadmin

export PGDATABASE=gpmaster

生效：

[gpadmin@gpmaster ~]$ source .bash_profile

編輯all_hosts_file文件，添加如下內(nèi)容：

[gpadmin@gpmaster ~]$ vi all_hosts_file

gpmaster

執(zhí)行如下命令驗(yàn)證用戶等效性

[gpadmin@gpmaster ~]$ gpssh-exkeys -f all_hosts_file

3.初始化系統(tǒng)：

編輯系統(tǒng)初始化的參數(shù)文件，這個(gè)文件的編輯可以使用模版，模板文件所在目錄如下：

[gpadmin@gpmaster ~]$ cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/

編輯gp參數(shù)文件，修改如下配置：

[gpadmin@gpmaster ~]$ vi gpinitsystem_config

declare -a DATA_DIRECTORY=(/app/data/gp1 /app/data/gp2 /app/data/gp3 /app/data/gp4)

MASTER_HOSTNAME=gpmaster

MASTER_DIRECTORY=/app/master

DATABASE_NAME=gpmaster

編輯seg_hosts_file文件

[gpadmin@gpmaster ~]$ vi seg_hosts_file

gpmaster

執(zhí)行初始化系統(tǒng)命令：

[gpadmin@gpmaster ~]$ gpinitsystem -c gpinitsystem_config -h seg_hosts_file

系統(tǒng)開始初始化，之后會(huì)看到如下提示：

Continue with Greenplum creation Yy/Nn>

輸入 Y ，按回車，系統(tǒng)會(huì)初始化完成

安裝結(jié)束可以連接GP數(shù)據(jù)庫了：

[gpadmin@gpmaster ~]$ psql -d gpmaster

psql (8.2.15)

Type "help" for help.

gpmaster=#

創(chuàng)建數(shù)據(jù)庫

[gpadmin@gpmaster ~]$ createdb testDB -E utf-8

給數(shù)據(jù)庫權(quán)限

[gpadmin@gpmaster ~]$ psql -d gpmaster

psql (8.2.15)

Type "help" for help.

gpmaster=# \c testDB

You are now connected to database "testDB" as user "gpadmin".

testDB=# alter role gpadmin with password 'gpadmin';

遠(yuǎn)程權(quán)限

[gpadmin@gpmaster ~]$ cd $MASTER_DATA_DIRECTORY/

[gpadmin@gpmaster gpseg-1]$ ls

base               pg_distributedlog     pg_stat_tmp            pg_xlog

global             pg_distributedxidmap  pg_subtrans            postgresql.conf

gp_dbid            pg_hba.conf           pg_tblspc              postmaster.opts

gpperfmon          pg_ident.conf         pg_twophase            postmaster.pid

pg_changetracking  pg_log                pg_utilitymodedtmredo

[gpadmin@gpmaster gpseg-1]$

[gpadmin@gpmaster gpseg-1]$ vi pg_hba.conf

host     testDB      gpadmin         192.168.96.1/32    md5

通過gpstop -u命令使配置生效

[gpadmin@gpmaster gpseg-1]$ gpstop -u

通過其他機(jī)器登錄數(shù)據(jù)庫

$ psql -h292.168.96.128 -p5432 -d testDB -Ugpadmin
