Installing Greenplum Community Edition (CE)

Post date: Apr 23, 2013 7:15:13 PM

Installing Greenplum Community edition (CE). Here are the step by step instructions on how to install the Greenplum Database CE software and get your single-node Greenplum Database system up and running.

Before installing we have to change following OS configuration parameters:

----------------

LINUX

---------------

In /etc/sysctl.conf:

sysctl.kernel.shmmax = 500000000

sysctl.kernel.shmmni = 4096

sysctl.kernel.shmall = 4000000000

sysctl.kernel.sem = 250 512000 100 2048

sysctl.kernel.sysrq = 1

sysctl.kernel.core_uses_pid = 1

sysctl.kernel.msgmnb = 65536

sysctl.kernel.msgmax = 65536

sysctl.kernel.msgmni = 2048

sysctl.net.ipv4.tcp_syncookies = 1

sysctl.net.ipv4.ip_forward = 0

sysctl.net.ipv4.conf.default.accept_source_route = 0

sysctl.net.ipv4.tcp_tw_recycle = 1

sysctl.net.ipv4.tcp_max_syn_backlog = 4096

sysctl.net.ipv4.conf.all.arp_filter = 1

sysctl.net.ipv4.ip_local_port_range = 1025 65535

sysctl.net.core.netdev_max_backlog = 10000

sysctl.vm.overcommit_memory = 2

For RHEL version 6.x platforms, do not include the sysctl. prefix in the above parameters, as follows:

xfs_mount_options = rw,noatime,inode64,allocsize=16m

kernel.shmmax = 500000000

kernel.shmmni = 4096

kernel.shmall = 4000000000

kernel.sem = 250 512000 100 2048

kernel.sysrq = 1

kernel.core_uses_pid = 1

kernel.msgmnb = 65536

kernel.msgmax = 65536

kernel.msgmni = 2048

net.ipv4.tcp_syncookies = 1

net.ipv4.ip_forward = 0

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 = 1025 65535

net.core.netdev_max_backlog = 10000

vm.overcommit_memory = 2

In /etc/security/limits.conf:

* soft nofile 65536

* hard nofile 65536

* soft nproc 131072

* hard nproc 131072

OPTIONAL

==================================================================================================================

In /etc/hosts:

Include the host names and all interface address names for every machine participating in your Greenplum Database system.

File system recommendations: XFS is the preferred file system on Linux platforms for data storage. Greenplum recommends the following xfs mount options:

rw,noatime,inode64,allocsize=16m

Also, each disk device file should have a read-ahead value of 16384. For example, to verify the read-ahead value of a disk device:

# /sbin/blockdev --getra /dev/sdb

=================================================================================================================

Add the Greenplum database Admin account:

# useradd gpadmin

# passwd gpadmin

# New password: password

# Retype new password: password

You cannot run the Greenplum Database SNE server as root. While dealing with Greenplum use this newly created user account

Installing

the Greenplum Database Community edition (CE):

1. Download or copy the Greenplum Database CE from www.greenplum.com/

2. Unzip the installer file:

# unzip greenplum-db-4.2.2.4-build-1-CE-RHEL5-x86_64.bin

3. Launch the installer using bash:

# /bin/bash greenplum-db-4.0.0.0-build-#-SingleNodeEdition-PLATFORM.bin

4. The installer prompts you to provide an installation path. Press ENTER to accept the default install path (/usr/local/greenplum-db-4.0.0.0), or enter new path

5. The installer installs the Greenplum Database CE software and creates a greenplum-db symbolic link one directory level above your version-specific Greenplum Database

6. Change the ownership of your Greenplum Database SNE installation so that it is owned by the gpadmin

# chown -R gpadmin /usr/local/greenplum-db-4.0.0.0

# chgrp -R gpadmin /usr/local/greenplum-db-4.0.0.0

7. Preparing the Data Directory Locations

Every Greenplum Database SNE instance has a designated storage area on disk that is called the data directory location.

8. Create or choose a directory that will serve as your master data storage area

On this location user data is not stored, instead metadata (data about the data) is stored. Here global system catalog resides

# mkdir /gpmaster

# chown gpadmin /gpmaster

# chgrp gpadmin /gpmaster

9. Create or choose the directories that will serve as your segment storage areas:

This is the file system location where the database data is stored.

# mkdir /gpdata1

# chown gpadmin /gpdata1

# chgrp gpadmin /gpdata1

# mkdir /gpdata2

# chown gpadmin /gpdata2

# chgrp gpadmin /gpdata2

10. Configuring Greenplum Database SNE / CE Environment Variables:

$ vi .bashrc

Then add following entry

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

now source it

$ source ~/.bashrc

11. Now let’s initialize Greenplum database:

Greenplum provides a utility called gpinitsystem which initializes a Greenplum Database system. After the Greenplum Database SNE system is initialized and started, you can then create and manage databases by connecting to the Greenplum master database process.

12. Log in to the system as the gpadmin user:

# su - gpadmin

13. Copy the single_hostlist example file from your Greenplum Database installation to the current directory:

$ cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/hostlist_singlenode .

14. Copy the gp_init_singlenode example file from your Greenplum Database SNE installation to the current directory:

$ cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_singlenode .

15. Edit the gp_init_singlenode file and enter your configuration settings, you can remain them default. Some default parameters in this file are:

ARRAY_NAME="GPDB SNE"

MACHINE_LIST_FILE=./hostlist_singlenode

SEG_PREFIX=gpsne

PORT_BASE=50000

declare -a DATA_DIRECTORY=(/disk1/gpdata1 /disk2//gpdata2)

MASTER_HOSTNAME=sachi

MASTER_DIRECTORY=/home/gpmaster

MASTER_PORT=5432

16. Run the gpssh-exkeys utility to exchange ssh keys for the local host:

$ gpssh-exkeys -h sachi

[gpadmin@dbaref ~]$ gpssh-exkeys -h dbaref

[STEP 1 of 5] create local ID and authorize on local host

[ERROR dbaref] authentication check failed:

ssh: connect to host dbaref port 22: Connection refused

[ERROR] cannot establish ssh access into the local host

to overcome this issue

1. Disable firewall

2. start sshd service if not started

[root@dbaref Downloads]# /sbin/service sshd status

Redirecting to /bin/systemctl status sshd.service

sshd.service - OpenSSH server daemon.

Loaded: loaded (/lib/systemd/system/sshd.service; disabled)

Active: inactive (dead)

CGroup: name=systemd:/system/sshd.service

[root@dbaref Downloads]# /sbin/service sshd start

Redirecting to /bin/systemctl start sshd.service

[root@dbaref Downloads]# /sbin/service sshd status

Redirecting to /bin/systemctl status sshd.service

sshd.service - OpenSSH server daemon.

Main PID: 2764 (sshd)

CGroup: name=systemd:/system/sshd.service

└ 2764 /usr/sbin/sshd -D

[root@dbaref Downloads]#

Now su to gpadmin and run it again

[gpadmin@dbaref ~]$ gpssh-exkeys -h dbaref

[STEP 1 of 5] create local ID and authorize on local host

... /home/gpadmin/.ssh/id_rsa file exists ... key generation skipped

[STEP 2 of 5] keyscan all hosts and update known_hosts file

[STEP 3 of 5] authorize current user on remote hosts

[STEP 4 of 5] determine common authentication file content

[STEP 5 of 5] copy authentication files to all remote hosts

[INFO] completed successfully

[gpadmin@dbaref ~]$

======================================================================

Note: I have struggled with this many times. Here is one more option.

[root@sachi ~]# mkdir /etc/ssh/gpadmin

[root@sachi ~]# cp /home/gpadmin/.ssh/authorized_keys /etc/ssh/gpadmin/

[root@sachi ~]# chown -R gpadmin:gpadmin /etc/ssh/gpadmin

[root@sachi ~]# chmod 755 /etc/ssh/gpadmin

[root@sachi ~]# chmod 644 /etc/ssh/gpadmin/authorized_keys

[root@sachi ~]# vi /etc/ssh/sshd_config

#RSAAuthentication yes

#PubkeyAuthentication yes

# changed .ssh/authorized_keys to /etc/ssh/gpadmin/authorized_keys <<<<<<<

AuthorizedKeysFile /etc/ssh/gpadmin/authorized_keys

#AuthorizedKeysCommand none

#AuthorizedKeysCommandRunAs nobody

Reboot the server

======================================================================

17. initialize Greenplum Database SNE:

$ gpinitsystem -c gpinitsystem_singlenode

[gpadmin@sachi ~]$ gpinitsystem -c gpinitsystem_singlenode

18. After the Greenplum Database SNE system is initialized and started, you can connect to the Greenplum master database process using the psql client program:

$ createdb mydb

$ psql mydb

19. Now export master data directory:

$ vi .bashrc

Then add following entry

export MASTER_DATA_DIRECTORY=/gpmaster/gpsne-1

now source it

$ source ~/.bashrc

20. Now you can perform any database operations using psql program (DDL, DML)

Uninstall Greenplum:

To uninstall run the following commands:

$ gpdeletesystem -d /gpmaster/gpsne-1

$ rm -rf /usr/local/greenplum-db-4.0.0.0

$ rm /usr/local/greenplum-db

You can remove the environment variable and restore the default setting of OS parameters(Optional)

# FILE NAME: gpinitsystem_singlenode

# A configuration file is needed by the gpinitsystem utility.

# This sample file initializes a Greenplum Database Single Node

# Edition (SNE) system with one master and two segment instances

# on the local host. This file is referenced when you run gpinitsystem.

################################################

# REQUIRED PARAMETERS

################################################

# A name for the array you are configuring. You can use any name you

# like. Enclose the name in quotes if the name contains spaces.

ARRAY_NAME="GPDB SINGLENODE"

# This specifies the file that contains the list of segment host names

# that comprise the Greenplum system. For a single-node system, this

# file contains the local OS-configured hostname (as output by the

# hostname command). If the file does not reside in the same

# directory where the gpinitsystem utility is executed, specify

# the absolute path to the file.

MACHINE_LIST_FILE=./hostlist_singlenode

# This specifies a prefix that will be used to name the data directories

# of the master and segment instances. The naming convention for data

# directories in a Greenplum Database system is SEG_PREFIX<number>

# where <number> starts with 0 for segment instances and the master

# is always -1. So for example, if you choose the prefix gpsne, your

# master instance data directory would be named gpsne-1, and the segment

# instances would be named gpsne0, gpsne1, gpsne2, gpsne3, and so on.

SEG_PREFIX=gpsne

# Base port number on which primary segment instances will be

# started on a segment host. The base port number will be

# incremented by one for each segment instance started on a host.

PORT_BASE=40000

# This specifies the data storage location(s) where the script will

# create the primary segment data directories. The script creates a

# unique data directory for each segment instance. If you want multiple

# segment instances per host, list a data storage area for each primary

# segment you want created. The recommended number is one primary segment

# per CPU. It is OK to list the same data storage area multiple times

# if you want your data directories created in the same location. The

# number of data directory locations specified will determine the number

# of primary segment instances created per host.

# You must make sure that the user who runs gpinitsystem (for example,

# the gpadmin user) has permissions to write to these directories. You

# may want to create these directories on the segment hosts before running

# gpinitsystem and chown them to the appropriate user.

declare -a DATA_DIRECTORY=(/gpdata1 /gpdata2)

# The OS-configured hostname of the Greenplum Database master instance.

MASTER_HOSTNAME=localhost

# The location where the data directory will be created on the

# Greenplum master host.

# You must make sure that the user who runs gpinitsystem

# has permissions to write to this directory. You may want to

# create this directory on the master host before running

# gpinitsystem and chown it to the appropriate user.

MASTER_DIRECTORY=/gpmaster

# The port number for the master instance. This is the port number

# that users and client connections will use when accessing the

# Greenplum Database system.

MASTER_PORT=5432

# The shell the gpinitsystem script uses to execute

# commands on remote hosts. Allowed value is ssh. You must set up

# your trusted host environment before running the gpinitsystem

# script. You can use gpssh-exkeys to do this.

TRUSTED_SHELL=ssh

# Maximum distance between automatic write ahead log (WAL)

# checkpoints, in log file segments (each segment is normally 16

# megabytes). This will set the checkpoint_segments parameter

# in the postgresql.conf file for each segment instance in the

# Greenplum Database system.

CHECK_POINT_SEGMENTS=8

# The character set encoding to use. Greenplum supports the

# same character sets as PostgreSQL. See 'Character Set Support'

# in the PostgreSQL documentation for allowed character sets.

# Should correspond to the OS locale specified with the

# gpinitsystem -n option.
