Note: 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 $ 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.
