CentOS和Ubuntu下安裝配置Greenplum資料庫叢集（包括安裝包和原始碼編譯安裝）
阿新 • • 發佈：2019-01-30
首先說一下，無論是CentOS/RedHat還是Ubuntu都可以按原始碼方式、安裝包方式編譯安裝。
1. 規劃
192.168.4.93（h93） 1個主master 2個主segment、2個映象segment
192.168.4.94（h94） 1個備master 2個主segment、2個映象segment
都安裝在/home/wslu/gp/gpsql目錄。
2. 安裝依賴
在h93和h94安裝以下依賴：
2.1. Ubuntu
apt-get install -y git-core apt-get install -y gcc g++ apt-get install -y ccache apt-get install -y libreadline-dev apt-get install -y bison flex apt-get install -y zlib1g-dev apt-get install -y openssl libssl-dev apt-get install -y libpam-dev apt-get install -y libcurl4-dev apt-get install -y libbz2-dev apt-get install -y python-dev apt-get install -y ssh apt-get install -y libcurl4-dev Package libcurl4-dev is a virtual package provided by: libcurl4-openssl-dev 7.38.0-4+deb8u2 libcurl4-nss-dev 7.38.0-4+deb8u2 libcurl4-gnutls-dev 7.38.0-4+deb8u2 apt-get install -y python-pip pip install lockfile pip install paramiko pip install setuptools pip install epydoc pip install psi Note: debian8 required pip install --pre psi
2.2. Centos
yum源要按照我的總結中的設定。
yum install –y git.x86_64 yum install –y gcc.x86_64 gcc-c++.x86_64 yum install –y ccache.x86_64 yum install readline.x86_64 readline-devel.x86_64 yum install bison.x86_64 bison-devel.x86_64 yum install flex.x86_64 flex-devel.x86_64 yum install zlib.x86_64 zlib-devel.x86_64 yum install -y openssl.x86_64 openssl-devel.x86_64 yum install -y pam.x86_64 pam-devel.x86_64 yum install –y libcurl.x86_64 libcurl-devel.x86_64 yum install bzip2-libs.x86_64 bzip2.x86_64 bzip2-devel.x86_64 yum install libssh2.x86_64 libssh2-devel.x86_64 yum install python-devel.x86_64 yum install -y python-pip.noarch 接著執行： pip install lockfile pip install paramiko pip install setuptools pip install epydoc pip install psi 或者執行： yum install python-lockfile.noarch yum install python-PSI.x86_64 yum install python-paramiko.noarch yum install python-setuptools.noarch yum install epydoc.noarch
3. 原始碼安裝
3.1. 克隆原始碼
在h93和h94執行：
$ mkdir /home/wslu/gp/greenplum
$ cd /home/wslu/gp/greenplum
$ git clone https://github.com/greenplum-db/gpdb.3.2. 編譯安裝
在h93和h94執行：
$ cd /home/wslu/gp/greenplum $ CFLAGS+="-O2" ./configure--prefix=/home/wslu/gp/gpsql --enable-debug --enable-depend --enable-cassert $ make $ make install
安裝時如果遇到某些python包(lockfile、 paramiko、PSI等)找不到，可以參考HAWQ， (原始碼https://github.com/apache/incubator-hawq)<hawq_src>/tools/bin/pythonSrc/ 下所有的壓縮包拷貝到/home/wslu/gp/greenplum/gpMgmt/bin/pythonSrc/ext/ 中，然後再make install即可。
至此叢集原始碼編譯完成。
4. 安裝包安裝
下載greenplum-db-4.3.6.1-build-2-RHEL5-x86_64.zip
$ unzip greenplum-db-4.3.6.1-build-2-RHEL5-x86_64.zip在h93和h94使用普通使用者安裝：
$./greenplum-db-4.3.6.1-build-2-RHEL5-x86_64.bin 安裝到 /home/wslu/gp/gpsql
5. 設定作業系統引數
在h93和h94執行下述設定：
5.1. 系統級引數配置
以下配置需要在root下進行配置，所以需要能夠得到root許可權。
首先是防火牆的設定：
service iptables status #檢視是否開啟了防火牆
service iptables stop #關閉防火牆
chkconfig iptables off #設定開機不會啟動防火牆其次是ssh的速度設定：
sed -i 's/^GSS/#&/g' /etc/ssh/sshd_config #用來加速SSH連線的
service sshd reload核心處理和記憶體方面的設定：
# 設定核心引數, 並在啟動時生效
sysctl -p - >>/etc/sysctl.conf <<EOF
# configurations
kernel.sysrq=1
kernel.core_pattern=core
kernel.core_uses_pid=1
kernel.msgmnb=65536
kernel.msgmax=65536
kernel.msgmni=2048
kernel.sem=25600 3200000 10000 14200
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=1
EOF如果配置叢集時，因為要設定的共享記憶體大於系統最大共享記憶體而報錯，則可以按照以下官方推薦的設定配置：
# vi /etc/sysctl.conf
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
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.overcommit_memory = 2檔案讀寫方面的設定：
# 設定limits
cat >>/etc/security/limits.d/99-kingbasedbcloud.conf <<EOF
#KingbaseDBCloud configurations
* soft nofile 65536
* hard nofile 65536
* soft nproc 131072
* hard nproc 131072
EOF5.2. 資料庫級的引數設定
GUC引數設定，此設定需要按照實際機器來進行配置，常用的配置有如下幾點：
work_mem=1GB
shared_buffers=2GB
max_connections=500
max_pool_size=2000
enable_mergejoin=off
enable_nestloop=off
max_prepared_transactions=50
autovacuum=off
interconnect_setup_timeout=12006. demo叢集
安裝完成後，就可以使用demo叢集了。
執行下面命令即可在本機建立包含3個segment，3個segment-mirror，1個master的叢集：
$ cd /home/wslu/gp/gpsql
$ source greenplum_path.sh
$ gpssh-exkeys –h localhost
$ cd gpAux/gpdemo
$ make cluster
$ source gpdemo-env.sh如果不想用demo叢集，可以直接跳過本小節。
7. 設定環境變數
$ source gpsql/greenplum_path.sh
$ exportMASTER_DATA_DIRECTORY=/home/wslu/gp/gpsql/data/master/gpseg-18. 交換key
在h93執行：
$ gpssh-exkeys –h h94會提示輸入h94的wslu使用者的密碼。（使用者必須和h93相同）
則h93和h94之間可以無密碼登陸了。
9.初始化叢集
（1） 在h93和h94執行下述指令，以建立資料目錄：
$ mkdir gpsql/data/primary gpsql/data/mirror gpsql/data/master –p（2） 在h93建立配置檔案configs/gpinitsystem_config，內容如下：
ARRAY_NAME="EMC Greenplum DW"
SEG_PREFIX=gpseg
PORT_BASE=40000
declare -a DATA_DIRECTORY=(/home/wslu/gp/gpsql/data/primary /home/wslu/gp/gpsql/data/primary)
MASTER_HOSTNAME=h93
MASTER_DIRECTORY=/home/wslu/gp/gpsql/data/master
MASTER_PORT=5432
TRUSTED_SHELL=ssh
CHECK_POINT_SEGMENTS=8
ENCODING=UNICODE
MIRROR_PORT_BASE=50000
REPLICATION_PORT_BASE=41000
MIRROR_REPLICATION_PORT_BASE=51000
declare -a MIRROR_DATA_DIRECTORY=(/home/wslu/gp/gpsql/data/mirror /home/wslu/gp/gpsql/data/mirror)注意：configs目錄是我自己建立的、便於儲存自定義配置檔案的目錄。該步驟的目的是建立一個初始化時要用的配置檔案，並沒有路徑的要求。
（3） 在h93建立配置檔案configs/hostfile_gpinitsystem，內容如下：
h93
h94注意：configs目錄是我自己建立的、便於儲存自定義配置檔案的目錄。該步驟的目的是建立一個初始化時要用的配置檔案，並沒有路徑的要求。
（4） 在h93執行下述指令初始化叢集：
[[email protected] gpsql]$ gpinitsystem -c configs/gpinitsystem_config -h configs/hostfile_gpinitsystem –a

11. 啟動叢集
以後，想手動啟動叢集，執行：
$ gpstart –a這裡說一下，每次想使用叢集的任何指令，必須執行：
$ source greenplum-path.sh
$ exportMASTER_DATA_DIRECTORY=/home/wslu/gp/gpsql/data/master/gpseg-1下文不再贅述。
12.停止叢集
$ gpstop –a13.重啟叢集
$ gpstop –a –r14. 檢視叢集狀態
$ gpstate –m | -e15.reload配置檔案
在不停止叢集情況下，若配置檔案修改，reload配置檔案：
$ gpstop –u16. 維護模式下啟動master
僅僅啟動master來執行維護管理任務，不會影響segment中的資料。例如，在維護模式下你可以僅連線master例項的資料庫並且編輯系統表設定。
1.執行gpstart使用-m選項：
$ gpstart –m2.維護模式下連線master來維護系統表。例如：
$ PGOPTIONS='-c gp_session_role=utility'psql template13.完成管理任務後，使master關閉工具模式。然後，重啟進入正常模式：
$ gpstop -m17.訪問資料庫
可以使用psql連線叢集：
[[email protected] gpsql]$ psql -p 5432 postgres
psql (8.3devel)
Type "help" for help.
postgres=#基本上常見命令與PostgreSQL的相同。可參考PostgreSQL官方手冊和Greenplum官方手冊。
18.GUC引數配置
使用gpconfig設定guc引數
$ gpconfig -c gp_vmem_protect_limit -v4096MBgpconfig可以設定master和所有segment的guc引數，也可以使用--masteronly引數只設置master的引數。設定完guc引數後需要根據guc引數型別決定重啟叢集或reload配置檔案。
顯示guc引數
$ psql –c ‘showstatement_mem;’ 或 gpconfig –show statement_mem
$ psql –c ‘show all;’ 或 gpconfig –l19.附錄：關於配置單機多節點的說明
如果要配置單機多節點，比如只想在h93配置2個主segment、2個映象segment、1個master，只需要把hostfile_config中的h94刪掉，然後在h93刪除data/primary，data/mirror，data/master目錄下的內容，重新初始化即可。
