简介
操作系统要求
Greenplum Database 6 runs on the following operating system platforms:
- Red Hat Enterprise Linux 64-bit 8.7 or later (As of Greenplum Database version 6.20. See the following Note)
- Red Hat Enterprise Linux 64-bit 7.x (See the following Note.)
- Red Hat Enterprise Linux 64-bit 6.x
- CentOS 64-bit 7.x
- CentOS 64-bit 6.x
- Ubuntu 18.04 LTS
- Oracle Linux 64-bit 7, using the Red Hat Compatible Kernel (RHCK)
依赖包要求

Greenplum Database 6 requires the following software packages on RHEL/CentOS 6/7 systems which are installed automatically as dependencies when you install the Greenplum RPM package)
- apr
- apr-util
- bash
- bzip2
- curl
- krb5
- libcgroup (RHEL/CentOS 6)
- libcgroup-tools (RHEL/CentOS 7)

Greenplum Database 6 uses Python 2.7.18, which is included with the product installation (and not installed as a package dependency).
软件下载
可以从以下2个地方下载：
1、从 Greenplum 的 GitHub 页面（https://github.com/greenplum-db/gpdb/releases）下载RPM 包
2、需要注册并登录到 Pivotal 公司官网（https://network.pivotal.io/products/vmware-tanzu-greenplum）进行下载
安装包大约66MB，如下：
1 2 3 4 | wget https://github.com/greenplum-db/gpdb/releases/download/6.25.3/open-source-greenplum-db-6.25.3-rhel7-x86_64.rpm -- 加速 wget https://ghproxy.com/https://github.com/greenplum-db/gpdb/releases/download/6.25.3/open-source-greenplum-db-6.25.3-rhel7-x86_64.rpm |
环境申请
本文以1个master+1个standby master，4个segment的集群示例，OS均为CentOS 7.6.1810，采用docker初始化环境。
每个segment主机上有4个Primary Segment Instance 和 4个Mirror Segment Instance共8个实例。
所以，该集群共有16个Primary实例和16个Mirror实例，再加1个master实例和1个standby master实例共34个数据库实例。
master对外服务的端口号为5432，其它segment的端口号为primary从6000-6003，对应的mirror为7000-7003

修改主机名
1 2 3 4 5 6 | hostnamectl set-hostname mdw hostnamectl set-hostname smdw hostnamectl set-hostname sdw1 hostnamectl set-hostname sdw2 hostnamectl set-hostname sdw3 hostnamectl set-hostname sdw4 |
修改内核参数
若是docker环境，则以下配置需要在宿主机运行。
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 | # blockdev预读尺寸应该被设置为16384 /sbin/blockdev --getra /dev/sdb /sbin/blockdev --setra 16384 /dev/sdb echo 'export LANG=en_US.UTF-8' >> /etc/profile sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/selinux/config setenforce 0 systemctl status firewalld.service systemctl disable firewalld.service systemctl start firewalld firewall-cmd --add-port=0-65535/tcp --permanent firewall-cmd --add-port=0-65535/udp --permanent firewall-cmd --reload firewall-cmd --list-ports systemctl stop firewalld.service sed -i 's/.*RemoveIPC.*/RemoveIPC=no/' /etc/systemd/logind.conf echo "RemoveIPC=no" >> /usr/lib/systemd/system/systemd-logind.service systemctl daemon-reload systemctl restart systemd-logind.service ll /lib64/security/pam_limits.so echo "session required /lib64/security/pam_limits.so" >> /etc/pam.d/login cat >> /etc/security/limits.conf <<"EOF" * soft nofile 655350 * hard nofile 655350 * soft nproc 655350 * hard nproc 655350 gpadmin soft priority -20 EOF sed -i 's/4096/655350/' /etc/security/limits.d/20-nproc.conf cat /etc/security/limits.d/20-nproc.conf ulimit -HSn 65535 cat >> /etc/sysctl.conf <<"EOF" fs.file-max=9000000 fs.inotify.max_user_instances = 1000000 fs.inotify.max_user_watches = 1000000 kernel.pid_max=4194304 kernel.shmmax = 4398046511104 kernel.shmmni = 4096 kernel.shmall = 4000000000 kernel.sem = 32000 1024000000 500 32000 vm.overcommit_memory=1 vm.overcommit_ratio=95 net.ipv4.ip_forward=1 vm.swappiness=20 vm.dirty_background_bytes = 0 vm.dirty_background_ratio = 5 vm.dirty_bytes = 0 vm.dirty_expire_centisecs = 600 vm.dirty_ratio = 10 vm.dirty_writeback_centisecs = 100 vm.vfs_cache_pressure = 500 vm.min_free_kbytes = 2097152 EOF sysctl -p cat >> /etc/ssh/sshd_config <<"EOF" MaxSessions 1000 MaxStartups 1000 # MaxStartups 50:80:200 EOF systemctl restart sshd docker restart mdw smdw sdw1 sdw2 sdw3 sdw4 |
修改/etc/hosts文件
在Greenplum中，习惯将Master机器叫做mdw，将Segment机器叫做sdw。dw的含义为Data Warehouse。
1 2 3 4 5 6 7 8 | cat >> /etc/hosts <<"EOF" 172.72.6.50 mdw 172.72.6.51 smdw 172.72.6.52 sdw1 172.72.6.53 sdw2 172.72.6.54 sdw3 172.72.6.55 sdw4 EOF |
mdw和sdw只是一个主机的别名，不影响程序去查找IP。
docker环境每次重启容器都会重置/etc/hosts文件的内容，但是这不会影响GreenPlum的正常运行。
也可以在创建容器的时候添加参数"--add-host='mdw:172.72.6.50'"来规避这个问题。
创建用户和集群配置文件（所有节点）
为所有节点创建gpadmin用户：
1 2 3 4 5 | 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:lhr" | chpasswd echo "gpadmin ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers |
为所有节点创建一个all_hosts文件，包含所有节点主机名：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | su - gpadmin mkdir -p /home/gpadmin/conf/ cat > /home/gpadmin/conf/all_hosts <<"EOF" mdw smdw sdw1 sdw2 sdw3 sdw4 EOF |
为所有节点创建一个 seg_hosts文件 ，包含所有的Segment Host的主机名：
1 2 3 4 5 6 7 8 9 | cat > /home/gpadmin/conf/seg_hosts <<"EOF" sdw1 sdw2 sdw3 sdw4 EOF |
配置互信
只在master节点（172.72.6.50）操作：
1 2 3 4 5 6 | ./sshUserSetup.sh -user root -hosts "mdw smdw sdw1 sdw2 sdw3 sdw4" -advanced -noPromptPassphrase ./sshUserSetup.sh -user gpadmin -hosts "mdw smdw sdw1 sdw2 sdw3 sdw4" -advanced -noPromptPassphrase chmod 600 /home/gpadmin/.ssh/config -- 测试 gpssh -f all_hosts date |
1、为了后续的维护方便，建议root和gpadmin用户都做互信的配置。
2、必须给600权限，否则会报错“.Bad owner or permissions on /home/gpadmin/.ssh/config”
安装GP软件（所有节点）
在所有节点以root用户操作：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 | yum install -y openssh openssh-clients openssh-server \ initscripts net-tools telnet which wget passwd lrzsz sudo unzip \ tree traceroute lsof file tar systemd sysstat curl \ strace less stress bash bash-completion sed zip \ yum-utils ethtool iputils screen yum install -y apr apr-util bash bzip2 curl krb5 libcurl \ libevent libxml2 libyaml zlib openldap openssh openssl \ openssl-libs perl readline rsync R sed tar zip krb5-devel \ libcgroup-tools libnsl -- 主要安装包 yum install -y apr apr-util bzip2 krb5-devel libyaml perl rsync zip libevent --downloadonly --downloaddir=/soft rpm -ivh net-tools*.rpm rpm -ivh libcgroup*.rpm rpm -ivh libcgroup-tools*.rpm rpm -ivh keyutils-libs-devel*.rpm rpm -ivh libcom_err-devel*.rpm rpm -ivh libkadm5*.rpm rpm -ivh krb5-libs*.rpm --nodeps rpm -ivh libkadm5*.rpm --nodeps rpm -ivh krb5-devel*.rpm --nodeps rpm -ivh libselinux-devel*.rpm --nodeps rpm -ivh libverto-devel*.rpm rpm -ivh apr*.rpm rpm -ivh apr-util*.rpm rpm -ivh bzip2*.rpm rpm -ivh libyaml*.rpm rpm -ivh perl*.rpm --nodeps rpm -ivh rsync*.rpm rpm -ivh zip*.rpm rpm -ivh libevent*.rpm rpm -ivh /soft/open-source-greenplum-db-6.25.3-rhel7-x86_64.rpm |
默认的安装路径是/usr/local，修改该路径gpadmin操作权限：
1 2 | chown -R gpadmin:gpadmin /usr/local/greenplum-db chown -R gpadmin:gpadmin /usr/local/greenplum-db-6.25.3 |
创建目录，用作集群数据的存储目录：
1 2 | mkdir -p /opt/greenplum/data/ chown -R gpadmin:gpadmin /opt/greenplum |
配置环境变量
1 2 3 4 5 6 7 8 9 | -- 所有节点 echo ". /usr/local/greenplum-db/greenplum_path.sh" >> /home/gpadmin/.bashrc -- master和standby master配置 echo "export MASTER_DATA_DIRECTORY=/opt/greenplum/data/master/gpseg-1" >> /home/gpadmin/.bashrc echo "export PGDATABASE=postgres" >> /home/gpadmin/.bashrc echo "export PGPORT=5432" >> /home/gpadmin/.bashrc source /home/gpadmin/.bashrc |
数据库初始化（重要）
该步为最核心最重要的命令过程！！！
Greenplum 配置文件模板都在/usr/local/greenplum-db/docs/cli_help/gpconfigs目录下，其中gpinitsystem_config是初始化 Greenplum 的模板。
在master节点操作：
