Greenplum 6.0安装教程

一、Greenplum简介

Greenplum数据库系统体系结构的高级概述。

Greenplum数据库通过在多个服务器或主机之间分配负载来存储和处理大量数据。
Greenplum中的逻辑数据库是一组单独的PostgreSQL数据库，这些数据库协同工作以呈现单个数据库映像。该主是入口点，Greenplum的数据库系统。
它是用户连接并提交SQL语句的数据库实例。
主服务器协调系统中其他数据库实例（称为segment）的工作负载，这些实例处理数据处理和存储。这些段通过互连（Greenplum数据库的网络层）相互之间和主机进行通信。

当前安装的测试环境如下所示：

主机名	ip	配置	系统版本	用途	数据库安装位置	数据安装目录
mdwh1	172.16.101.112	6c,16G	CentOS Linux release 7.5.1804 (Core)	master主节点	/usr/local/greenplum-db	/data/master
sdwh1	172.16.101.113	6c,16G	CentOS Linux release 7.5.1804 (Core)	segment节点,mirro节点	/usr/local/greenplum-db	/data/primary,/data/mirro
sdwh1	172.16.101.114	6c,16G	CentOS Linux release 7.5.1804 (Core)	segment节点,mirro节点	/usr/local/greenplum-db	/data/primary,/data/mirro

注意

二、配置系统（所有服务器都需要配置）

1. 确保您的主机系统满足平台要求中所述的要求。

2. 禁用SELinux和防火墙软件。

禁用SELinux1.以root用户身份检查SELinux的状态：[root@mdwh ~]# sestatusSELinux status: disabled2.如果未禁用SELinux，请通过编辑/etc/selinux/config文件：SELINUX=disabled禁用防火墙systemctl stop firewalld && systemctl disable firewalld.service

3. 设置所需的操作系统参数。

vi /etc/sysctl.conf

参考参数如下:kernel.shmall = 4000000000
kernel.shmmax = 500000000
kernel.shmmni = 4096
vm.overcommit_memory = 2
vm.overcommit_ratio = 95
net.ipv4.ip_local_port_range = 10000 65535
kernel.sem = 500 2048000 200 40960
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.msgmni = 2048
net.ipv4.tcp_syncookies = 1
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp_max_syn_backlog = 4096
net.ipv4.conf.all.arp_filter = 1
net.core.netdev_max_backlog = 10000
net.core.rmem_max = 2097152
net.core.wmem_max = 2097152
vm.swappiness = 10
vm.zone_reclaim_mode = 0
vm.dirty_expire_centisecs = 500
vm.dirty_writeback_centisecs = 100
vm.dirty_background_ratio = 0 # See Note 5
vm.dirty_ratio = 0
vm.dirty_background_bytes = 1610612736
vm.dirty_bytes = 4294967296

修改立即生效

sysctl -p

修改文件数，进程数的限制vi /etc/security/limits.conf,在文件末尾新增以下内容

* soft nofile 524288
* hard nofile 524288
* soft nproc 131072
* hard nproc 131072

4. 创建ip和主机名映射：vi /etc/hosts

172.16.101.112 mdwh
172.16.101.113 sdwh1
172.16.101.114 sdwh2

5. 创建gpadmin帐户。

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

6. 配置root和gpadmin用户SSH免密登录

root用户登录主节点：1. ssh-keygen 生成公钥和私钥
2. 用ssh-copy-id将公钥复制到远程机器中ssh-copy-id sdwh1ssh-copy-id sdwh2gpadmin用户登录主节点：1. ssh-keygen 生成公钥和私钥
2. 用ssh-copy-id将公钥复制到远程机器中ssh-copy-id sdwh1ssh-copy-id sdwh2

三、安装Greenplum数据库

下载安装包，放到master节点服务器上

1.下载greenplum-db-6.0.0-rhel7-x86_64.rpm文件，下载地址https://github.com/greenplum-db/gpdb/releases/tag/6.0.02.yum install greenplum-db-6.0.0-rhel7-x86_64.rpm或者
rpm -ivh greenplum-db-6.0.0-rhel7-x86_64.rpm

master节点开始安装rpm包

[root@mdwh ~]# rpm -ivh greenplum-db-6.0.0-rhel7-x86_64.rpm 准备中...                          ################################# [100%]正在升级/安装...1:greenplum-db-6.0.0-1.el7         ################################# [100%]

设置环境变量

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

新建gpconfigs文件夹，存放gp安装过程中所使用到的配置文件

[root@mdwh ~]# mkdir /usr/local/greenplum-db-6.0.0/gpconfigs[root@mdwh gpadmin]# cd /usr/local/greenplum-db-6.0.0/gpconfigsallhosts: 所有服务器的主机名
seghosts: 所有Segment节点的主机名[root@mdwh gpconfigs]# vi allhosts写入mdwh   sdwh1sdwh2[root@mdwh gpconfigs]# vi seghosts写入sdwh1sdwh2

通过gpssh在所有的segment节点进行安装rpm包

以下命令以重做ssh密钥交换

[root@mdwh gpconfigs]# gpssh-exkeys -f seghosts
[STEP 1 of 5] create local ID and authorize on local host... /root/.ssh/id_rsa file exists ... key generation skipped[STEP 2 of 5] keyscan all hosts and update known_hosts file[STEP 3 of 5] retrieving credentials from remote hosts... send to sdwh1... send to sdwh2[STEP 4 of 5] determine common authentication file content[STEP 5 of 5] copy authentication files to all remote hosts... finished key exchange with sdwh1... finished key exchange with sdwh2[INFO] completed successfully

执行具体的安装操作

1. 通过gpssh -f seghosts连接上所有的segment节点[root@mdwh gpconfigs]# gpssh -f seghosts => pwd  [sdwh1] /root[sdwh2] /root=> pwd[sdwh1] /root[sdwh2] /root2. 从主机复制rpm包=> scp mdwh:/root/greenplum-db-6.0.0-rhel7-x86_64.rpm ./greenplum-db-6.0.0-rhel7-x86_64.rpm             0%    0     0.0KB/s   --:-- greenplum-db-6.0.0-rhel7-x86_64.rpm             1% 2000KB   1.9MB/s   01:31 greenplum-db-6.0.0-rhel7-x86_64.rpm             6%   11MB   2.4MB/s   01:08 greenplum-db-6.0.0-rhel7-x86_64.rpm            91%  157MB  16.7MB/s   00:00 greenplum-db-6.0.0-rhel7-x86_64.rpm           100%  172MB  49.2MB/s   00:03    greenplum-db-6.0.0-rhel7-x86_64.rpm             0%    0     0.0KB/s   --:-- greenplum-db-6.0.0-rhel7-x86_64.rpm            30%   53MB  53.1MB/s   00:02 greenplum-db-6.0.0-rhel7-x86_64.rpm            44%   76MB  49.6MB/s   00:01 greenplum-db-6.0.0-rhel7-x86_64.rpm            54%   94MB  46.3MB/s   00:01 greenplum-db-6.0.0-rhel7-x86_64.rpm            75%  130MB  45.0MB/s   00:00 greenplum-db-6.0.0-rhel7-x86_64.rpm           100%  172MB  31.9MB/s   00:05    => ll3. 安装rpm包 => rpm -ivh /root/greenplum-db-6.0.0-rhel7-x86_64.rpm[sdwh1] 准备中...                          ################################# [100%][sdwh1] 正在升级/安装...[sdwh1]    1:greenplum-db-6.0.0-1.el7         ################################# [100%][sdwh2] 准备中...                          ################################# [100%][sdwh2] 正在升级/安装...[sdwh2]    1:greenplum-db-6.0.0-1.el7         ################################# [100%]=> => chown -R gpadmin:gpadmin /usr/local/greenplum*[sdwh1][sdwh2]=>

在segment节点创建primary、mirro存储目录

=> mkdir /data/primary && chown -R gpadmin:gpadmin /data/primary
[sdwh1]
[sdwh2]
=> mkdir /data/mirror && chown -R gpadmin:gpadmin /data/mirror
[sdwh1]
[sdwh2]
=> exit

修改master节点的greenplum安装目录权限

[root@mdwh gpconfigs]# chown -R gpadmin:gpadmin /usr/local/greenplum*

切换gpadmin用户，进行greenplum数据初始化操作

1. 切换用户[root@mdwh gpconfigs]# su gpadmin2. 从greenplum安装目录copy初始化文件[gpadmin@mdwh gpconfigs]$ cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config /usr/local/greenplum-db/gpconfigs/3. 编辑gpinitsystem_config配置文件vim /usr/local/greenplum-db/gpconfigs/gpinitsystem_config---本例配置文件如下：# FILE NAME: gpinitsystem_config# Configuration file needed by the gpinitsystem#################################################### REQUIRED PARAMETERS#################################################### Name of this Greenplum system enclosed in quotes.ARRAY_NAME="Greenplum Data Platform"#### Naming convention for utility-generated data directories.SEG_PREFIX=gpseg#### Base number by which primary segment port numbers #### are calculated.PORT_BASE=6000#### File system location(s) where primary segment data directories #### will be created.

13.查看segment状态 gpstate -m

设置任何ip都可访问greenplum

1. 进入master节点服务器2. 编辑pg_hba.conf[gpadmin@mdwh gpconfigs]$ vim /data/master/gpseg-1/pg_hba.conf 尾行加入：host     all        all         0.0.0.0/0     trust

四、启动和停止Greenplum数据库

启动Greenplum数据库

gpstart

重新启动Greenplum数据库，停止Greenplum数据库系统，然后重新启动它。

gpstop -r

仅重新加载配置文件更改，将更改重新加载到Greenplum数据库配置文件，而不会中断系统。

gpstop -u

在维护模式下启动主机，仅启动主服务器以执行维护或管理任务，而不会影响段上的数据。

gpstart -m

停止Greenplum数据库

gpstop

要以快速模式停止Greenplum数据库

gpstop -M fast
