1、安裝說明
1.1、環境說明
| 名稱 | 版本 |
| 操作系統 | CentOS Linux release 7.5.1804 |
| greenplum | greenplum-db-5.21.0-rhel6-x86_64.rpm |
1.2、集群介紹
5台虛擬機，1個master節點，4個segment的集群，示例：
wuxiang-test-1（master）
wuxiang-test-2
wuxiang-test-3
wuxiang-test-4
wuxiang-test-5
1.3、修改主機名稱
由於虛擬機重啟后主機名稱變為localhost，所以要永久性地修改為wuxiang-test-1這種形式，進行如下操作：
2、安裝准備
2.1、修改各節點hosts（所有節點）
[root@wuxiang-test-2 ~]# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.40.218 wuxiang-test-1 192.168.40.238 wuxiang-test-2 192.168.40.239 wuxiang-test-3 192.168.40.240 wuxiang-test-4 192.168.40.241 wuxiang-test-5
注：標注了所有節點的配置項可以在安裝greenplum並配置免密后用gpssh統一操作3.3。
2.2、修改network文件（所有節點，名稱有差異）
[root@wuxiang-test-2 ~]# cat /etc/sysconfig/network NISDOMAIN=QI HOSTNAME=wuxiang-test-2
2.3修改內核文件（所有節點）
[root@wuxiang-test-2 ~]# cat /etc/sysctl.conf vm.swappiness = 10 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
最后使配置生效：
[root@wuxiang-test-2 ~]# sysctl -p
2.4、修改進程數文件（所有節點）
[root@wuxiang-test-2 ~]# cat /etc/security/limits.d/20-nproc.conf # Default limit for number of user's processes to prevent # accidental fork bombs. # See rhbz #432903 for reasoning. * soft nproc 4096 root soft nproc unlimited
2.5、關閉防火牆（所有節點）
查看防火牆狀態：firewall-cmd --state
關閉防火牆：systemctl stop firewalld.service
禁止防火牆開機啟動：systemctl disable firewalld.service
修改配置（所有節點）：
[root@wuxiang-test-2 ~]# cat /etc/selinux/confin SELINUX=disabled SELINUXTYPE=targeted
2.6、創建用戶（各節點共享）
groupadd -g 530 gpadmin useradd -g 530 -u 530 -m -d /home/gpadmin -s /bin/bash gpadmin chown -R gpadmin:gpadmin /home/gpadmin echo "gpadmin" | passwd --stdin gpadmin
3、安裝Greenplum DB
3.1、在Master節點上安裝Greenplum
安裝包下載地址：https://network.pivotal.io/products/pivotal-gpdb/#/releases/413133/file_groups/1866
安裝包是rpm格式的執行rpm安裝命令：
[root@wuxiang-test-1 ~]# rpm -ivh greenplum-db-5.21.0-rhel6-x86_64.rpm
默認的安裝路徑是/usr/local。
將/usr/local/greenplum-db-5.21.0文件拷貝至所有節點（可以壓縮再解壓，也可以使用gpssh方式）
然后需要修改該路徑gpadmin操作權限（所有節點）：
chown -R gpadmin:gpadmin /usr/local
chown -R gpadmin:gpadmin /opt
建立軟連接（所有節點）:
ln -s /usr/local/greenplum-db-5.21.0 greenplum-db
3.2、創建hostlist、seg_hosts文件
切換gpadmin用戶，創建conf文件夾，
[gpadmin@wuxiang-test-1 ~]# cd conf/
[gpadmin@wuxiang-test-1 conf]# cat hostlist
wuxiang-test-1
wuxiang-test-2
wuxiang-test-3
wuxiang-test-4
wuxiang-test-5
[gpadmin@wuxiang-test-1 conf]# cat seg_hosts
wuxiang-test-2
wuxiang-test-3
wuxiang-test-4
wuxiang-test-5
3.3、配置免密連接
[root@ wuxiang-test-1 ~]# su gpadmin [gpadmin@ wuxiang-test-1 ~]# source /usr/local/greenplum-db/greenplum_path.sh [gpadmin@ wuxiang-test-1 ~]# gpssh-exkeys -f /home/gpadmin/conf/hostlist [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 ... send to wuxiang-test-1 ... send to wuxiang-test-2 ... send to wuxiang-test-3 ... send to wuxiang-test-4 ... send to wuxiang-test-5 #提示：這里提示輸入各個子節點gpadmin用戶密碼 [STEP 4 of 5] determine common authentication file content [STEP 5 of 5] copy authentication files to all remote hosts ... finished key exchange with wuxiang-test-1 ... finished key exchange with wuxiang-test-2 ... finished key exchange with wuxiang-test-3 ... finished key exchange with wuxiang-test-4 ... finished key exchange with wuxiang-test-5 [INFO] completed successfully
測試免密是否成功：
[gpadmin@wuxiang-test-1 ~]# ssh wuxiang-test-4
或者用gpssh：
[gpadmin@wuxiang-test-1 ~]$ gpssh -f /home/gpadmin/conf/hostlist => pwd [wuxiang-test-1] /home/gpadmin [wuxiang-test-4] /home/gpadmin [wuxiang-test-5] /home/gpadmin [wuxiang-test-3] /home/gpadmin [wuxiang-test-2] /home/gpadmin => exit
顯示上面內容，即為成功。
4、初始化數據庫
4.1、創建資源目錄
source /usr/local/ greenplum-db/greenplum_path.sh gpssh -f /home/gpadmin/conf/hostlist #統一處理所有節點 #創建資源目錄 /opt/greenplum/data下一系列目錄（生產目錄個數可根據需求生成） => mkdir -p /opt/greenplum/data/master => mkdir -p /opt/greenplum/data/primary => mkdir -p /opt/greenplum/data/mirror => mkdir -p /opt/greenplum/data2/primary => mkdir -p /opt/greenplum/data2/mirror
4.2、環境變量配置（所有節點）
[gpadmin@wuxiang-test-1 ~]$ cat /home/gpadmin/.bash_profile # .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/.local/bin:$HOME/bin export PATH source /usr/local/greenplum-db/greenplum_path.sh export MASTER_DATA_DIRECTORY=/opt/greenplum/data/master/gpseg-1 export GPPORT=5432 export PGDATABASE=gp_sydb
注：不能用gpssh編輯文件
讓環境變量生效：
source /home/gpadmin/.bash_profile
4.3、NTP配置
啟用master節點上的ntp，並在Segment節點上配置和啟動NTP：
#master 節點 [root@wuxiang-test-1 ~]# echo "server 127.127.1.0" >>/etc/ntp.conf #Segment節點 [root@wuxiang-test-2 ~]# echo "server wuxiang-test-1 perfer" >>/etc/ntp.conf #master節點 [root@wuxiang-test-1 ~]# systemctl start ntpd [root@wuxiang-test-1 ~]# systemctl enable ntpd
4.4、檢查各節點的連通性
[gpadmin@wuxiang-test-1 bin]$ cd /usr/local/greenplum-db/bin
[gpadmin@wuxiang-test-1 bin]$ gpcheckperf -f /home/gpadmin/conf/hostlist -r N -d /tmp /usr/local/greenplum-db/./bin/gpcheckperf -f /home/gpadmin/conf/hostlist -r N -d /tmp ------------------- -- NETPERF TEST ------------------- [Warning] retrying with port 23012 [Warning] retrying with port 23024 [Warning] retrying with port 23036 [Warning] retrying with port 23048 [Warning] retrying with port 23060 ==================== == RESULT ==================== Netperf bisection bandwidth test wuxiang-test-1 -> wuxiang-test-2 = 110.490000 wuxiang-test-3 -> wuxiang-test-4 = 112.120000 wuxiang-test-5 -> wuxiang-test-1 = 108.990000 wuxiang-test-2 -> wuxiang-test-1 = 102.830000 wuxiang-test-4 -> wuxiang-test-3 = 112.010000 wuxiang-test-1 -> wuxiang-test-5 = 108.930000 Summary: sum = 655.37 MB/sec min = 102.83 MB/sec max = 112.12 MB/sec avg = 109.23 MB/sec median = 110.49 MB/sec
我在安裝過程中由於反復嘗試了多次，出現了如下錯誤：
[gpadmin@wuxiang-test-1 bin]$ gpcheckperf -f /home/gpadmin/conf/hostlist -r N -d /tmp /usr/local/greenplum-db/./bin/gpcheckperf -f /home/gpadmin/conf/hostlist -r N -d /tmp ------------------- -- NETPERF TEST ------------------- [Warning] retrying with port 23012 [Warning] retrying with port 23024 [Warning] retrying with port 23036 [Warning] retrying with port 23048 [Error] unable to start netserver ... abort netperf test ==================== == RESULT ====================
經嘗試是由於端口占用過多導致，gpcheckperf文件中默認是嘗試5次，如果5次都沒連通，則會報這個錯誤，由於未找到刪除端口辦法，所以修改了gpcheckperf文件中xrange為10次
4.5、執行初始化
[gpadmin@wuxiang-test-1 bin]$ cd /usr/local/greenplum-db/docs/cli_help/gpconfigs [gpadmin@wuxiang-test-1 gpconfigs]$ cp gpinitsystem_config initgp_config [gpadmin@wuxiang-test-1 gpconfigs]$ vim initgp_config
修改內容：
#目錄與4.1創建的目錄一致
declare -a DATA_DIRECTORY=(/opt/greenplum//data/primary /opt/greenplum//data/primary /opt/greenplum//data/primary /opt/greenplum//data2/primary /opt/greenplum//data2/primary /opt/greenplum//data2/primary) declare -a MIRROR_DATA_DIRECTORY=(/opt/greenplum/data/mirror /opt/greenplum/data/mirror /opt/greenplum/data/mirror /opt/greenplum/data2/mirror /opt/greenplum/data2/mirror /opt/greenplum/data2/mirror) ARRAY_NAME="gp_sydb" #初始化數據庫名稱 MASTER_HOSTNAME=wuxiang-test-1 #主節點名稱 MASTER_DIRECTORY=/opt/greenplum/data/master MASTER_DATA_DIRECTORY=/opt/greenplum/data/master/gpseg-1 DATABASE_NAME=gp_sydb MACHINE_LIST_FILE=/home/gpadmin/conf/seg_hosts

若初始化失敗，則重新執行4.1，刪除已初始化的數據。
執行psql -d postgres進入到數據庫，則說明安裝完成。
5、數據庫操作
5.1、停止和啟動集群
gpstop -M fast
gpstart -a
5.2、登陸數據庫
$ psql -d postgres
5.3、集群狀態
gpstate -e #查看mirror的狀態 gpstate -f #查看standby master的狀態 gpstate -s #查看整個GP群集的狀態 gpstate -i #查看GP的版本 gpstate --help #幫助文檔，可以查看gpstate更多用法
目前為止數據庫已經操作完畢。默認只有本地可以連數據庫，如果需要別的I可以連，需要修改gp_hba.conf文件。
