gp服務器列表

 144.131.252.198 mdw                master 主節點
 144.131.252.199 sdw1-1             數據節點1
 144.131.252.144 sdw2-1             數據節點2
 144.131.252.195 sdw3-1             主節點切換備用節點

1.修改系統配置項

1.1 關閉SELINUX
vi /etc/selinux/config

SELINUX=disabled

1.2 關閉防火墻

systemctl status firewalld
systemctl stop firewalld.service
systemctl disable firewalld.service
iptable -L -n

1.3
修改內核配置參數,并執行 sysctl -p使之生效
vi /etc/sysctl.conf

kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sem = 2000 4096000 2000 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
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.overcommit_memory = 2

1.4
vi /etc/security/limits.conf

* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072

1.5
配置集群中各節點hosts信息
vi /etc/hosts

144.131.252.198    mdw        # master node
144.131.252.199    sdw1-1     # segment node 1
144.131.252.144    sdw2-1     # segment node 2
144.131.252.195    sdw3-1     # segment node 3

2 安裝greenplum-db

2.1 從https://network.pivotal.io/pr...
greenplum-db-5.4.0-rhel7-x86_64.rpm
greenplum-cc-web-3.3.1-LINUX-x86_64.zip
拷貝至mdw(144.131.252.198)主節點/opt目錄下
執行

tar -xzvf greenplum-cc-web-3.3.1-LINUX-x86_64.zip
rpm -ivh greenplum-db-5.4.0-rhel7-x86_64.rpm
unzip greenplum-db-5.4.0-rhel7-x86_64.zip
./greenplum-db-5.4.0-rhel7-x86_64.bin

2.2 按照提示輸入安裝目錄

    /opt/greenplum-db

執行

    ./greenplum-cc-web-3.3.1-LINUX-x86_64.bin

按照提示輸入安裝目錄

    /opt/greenplum-cc-web

解壓完成后創建gpadmin用戶和組，用來管理greenplum-db

    groupadd gpadmin                    # 創建分組
    useradd gpadmin -g gpadmin            # 創建用戶并分配組
    passwd gpadmin                        # 為gpadmin分配密碼
    cd /opt/greenplum-db
    chown -R gpadmin:gpadmin greenplum-db/
    chown -R gpadmin:gpadmin greenplum-cc-web/

2.3 切換到gpadmin用戶下：

    su - gpadmin
    mkdir -p /opt/greenplum-db/gpconfigs
    cd /opt/greenplum-db/gpconfigs

創建配置文件

vim hostfile_exkeys    

    mdw
    sdw1-1
    sdw2-1
    sdw3-1

vi hostfile

    sdw1-1
    sdw2-1
    sdw3-1

2.4 在gpadmin用戶下添加環境變量

vi ~/.bashrc

    #添加以下內容
    export LD_LIBRARY_PATH=$GPHOME/lib
    export MASTER_DATA_DIRECTORY=/home/gpadmin/gpdata/master/gpseg-1
    . /opt/greenplum-db/greenplum_path.sh
    . /opt/greenplum-cc-web/gpcc_path.sh

     source ~/.bashrc

切換到root用戶下，導出環境變量

su - root
vi ~/.bashrc

    #添加以下內容
    export LD_LIBRARY_PATH=$GPHOME/lib
    export MASTER_DATA_DIRECTORY=/home/gpadmin/gpdata/master/gpseg-1
    . /opt/greenplum-db/greenplum_path.sh
    . /opt/greenplum-cc-web/gpcc_path.sh

執行

source ~/.bashrc
gpssh-exkeys -f hostfile_exkeys    #拷貝mster節點公鑰至各segment節點             
gpseginstall -f /opt/greenplum-db/gpconfigs/hostfile_exkeys -p gpadmin 

注:

gpssh-exkeys -f hostfile_exkeys
將會在master節點生成公私鑰，并拷貝至hostfile_exkeys各segment節點，實現后續無密鑰登陸
gpseginstall -f /opt/greenplum-db/gpconfigs/hostfile_exkeys -p gpadmin
使用默認用戶名(gpadmin) 、密碼：gpadmin 在各segment節點安裝Greenplum—Db

2.5 在master及各segment節點創建數據存儲目錄

mkdir /home/gpadmin/gpdata/master
cd /home/gpadmin/
chown -R gpadmin:gpadmin gpdata/master
gpssh -f /opt/greenplum-db/gpconfigs/hostfile -e "mkdir -p /home/gpadmin/gpdata/data1/primary;mkdir -p /home/gpadmin/gpdata/data2/primary”
gpssh -f /opt/greenplum-db/gpconfigs/hostfile -e "mkdir -p /home/gpadmin/gpdata/data1/mirror;mkdir -p /home/gpadmin/gpdata/data2/mirror"
gpssh -f /opt/greenplum-db/gpconfigs/hostfile -e "chown -R gpadmin:gpadmin /home/gpadmin/gpdata"
gpssh -f /opt/greenplum-db/gpconfigs/hostfile_exkeys -v -e "ntpd"

切換到gpadmin用戶下,初始化數據庫集群

su - gpadmin
cd /opt/greenplum-db/
cp /opt/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config /opt/greenplum-db/gpconfigs/gpinitsystem_config
vi /opt/greenplum-db/gpconfigs/gpinitsystem_config

###修改以下內容
MASTER_HOSTNAME=mdw
PORT_BASE=40000
declare -a DATA_DIRECTORY=(/home/gpadmin/gpdata/data1/primary /home/gpadmin/gpdata/data1/primary /home/gpadmin/gpdata/data2/primary /home/gpadmin/gpdata/data2/primary)
MASTER_DIRECTORY=/home/gpadmin/gpdata/master
MASTER_PORT=5432
MIRROR_PORT_BASE=50000
REPLICATION_PORT_BASE=41000
MIRROR_REPLICATION_PORT_BASE=51000
declare -a MIRROR_DATA_DIRECTORY=(/home/gpadmin/gpdata/data1/mirror /home/gpadmin/gpdata/data1/mirror /home/gpadmin/gpdata/data2/mirror /home/gpadmin/gpdata/data2/mirror)
DATABASE_NAME=gpdb
MACHINE_LIST_FILE=/opt/greenplum-db/gpconfigs/hostfile

2.6 配置修改完成之后，執行以下命令初始化數據庫

    gpinitsystem -c gpconfigs/gpinitsystem_config -h         gpconfigs/hostfile

按照提示輸入相應信息，初始化完成后修改master節點：

vi /home/gpadmin/gpdata/master/gpseg-/pg_hba.conf

    #添加以下內容(允許172.16網段通過密碼登陸)
    host     all         gpadmin         172.16.1.1/16       md5

psql修改數據庫密碼:

    psql -d gpdb
    gpdb=# alter user gpadmin with password "gpadmin"
    gpdb=# q
    重啟greenplumdb集群

gpstop -a
gpstart -a

2.7 啟動greenplum-db commond center(gpcc)

    gpperfmon_install --enable --port 5432 --password gpadmin

重啟greenplumdb集群，加載gpperfmon_install采集數據

gpstop -a
gpstart -a

啟動web控制臺界面

gpcmdr --setup

按照提示輸入實例名、監聽端口信息等

#Please enter the instance name
gpcc
#Press ENTER to use instance name
gpcc
#Is the master host for the Greenplum Database remote? Yy/Nn (default=N)
N
#What port does the Greenplum Database use? (default=5432)
5432
#Enable kerberos login for this instance? Yy/Nn (default=N)
N
#What port would you like the new web server to use for this instance? (default=28080)
28080

啟動、停止

gpcmdr --start  #啟動
gpcmdr --stop   #停止
