greenplum单机安装

原文链接:https://blog.51cto.com/jxzhfei/1766666

环境:

服务器版本:centos 6.5

数据库版本:greenplum-db-4.2.8.5-build-1-RHEL5-x86_64.zip

 

1.创建用户和组gpadmin

groupadd -g  3030 gpadmin

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

passwd gpadmin

 

 

配置内核参数,添加如下内容:

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

 

以上参数可以根据自己系统配置做适当修改

手工执行命令,让参数生效

[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

 

 

配置用户ssh用户无密码登录,单机也得配置

[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.安装GP软件

方式一:

[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

 

 

方式二:

[root@gpmaster ~]# rpm -ivh greenplum-db-4.2....

 

创建instance需要的目录

[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

 

修改目录属主:

[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用户环境配置:

[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

编辑all_hosts_file文件,添加如下内容:

[gpadmin@gpmaster ~]$ vi all_hosts_file

gpmaster

 

执行如下命令验证用户等效性

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

 

3.初始化系统:

编辑系统初始化的参数文件,这个文件的编辑可以使用模版,模板文件所在目录如下:

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

 

编辑gp参数文件,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

 

编辑seg_hosts_file文件

[gpadmin@gpmaster ~]$ vi seg_hosts_file

gpmaster

 

执行初始化系统命令:

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

 

系统开始初始化,之后会看到如下提示:

Continue with Greenplum creation Yy/Nn>

输入 Y ,按回车,系统会初始化完成

 

 

安装结束可以连接GP数据库了:

[gpadmin@gpmaster ~]$ psql -d gpmaster

psql (8.2.15)

Type "help" for help.

 

gpmaster=#

 

 

创建数据库

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

 

给数据库权限

[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';

 

 

远程权限

[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

pg_clog            pg_multixact          PG_VERSION

[gpadmin@gpmaster gpseg-1]$

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

host     testDB      gpadmin         192.168.96.1/32    md5

 

通过gpstop -u命令使配置生效

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

 

通过其他机器登录数据库

$ psql -h192.168.96.128 -p5432 -d testDB -Ugpadmin
