禁用SELinux和防火墙软件

对于运行RHEL或CentOS的所有Greenplum数据库主机系统，必须禁用SELinux。跟着这些步骤：

以root用户身份检查SELinux的状态：

[gpadmin@aivmp-bigdata0001 ~]# sestatus
SELinux status:                 disabled

如果未禁用SELinux，请通过编辑/etc/selinux/config文件。以root身份更改文件如下：
```
SELINUX=disabled
```
如果系统上安装了系统安全服务守护程序（SSSD），请编辑SSSD配置文件并设置

selinux_provider 的参数 .以防止即使禁用SELinux也可能发生与SELinux相关的SSH身份验证拒绝。以root用户身份，编辑/etc/sssd/sssd.conf 并添加以下参数：
```
selinux_provider=none
```
重新引导系统以应用所做的任何更改，并验证SELinux已禁用。

您还应该禁用防火墙软件,请按照以下步骤禁用 iptables

对于具有防火墙，检查状态防火墙。使用命令：

[gpadmin@aivmp-bigdata0001 ~]$ systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)
   Active: inactive (dead)
     Docs: man:firewalld(1)

如有必要，以root用户身份执行这些命令以禁用防火墙：
```
systemctl stop firewalld.service
systemctl disable firewalld.service
```

配置Hosts

同步集群时间

yum install ntp ntpdate -y
sudo ntpdate cn.pool.ntp.org && hwclock --systohc

创建Greenplum管理用户

创建 gpadmin组和用户。

groupadd gpadmin 
useradd gpadmin -r -m -g gpadmin 
passwd gpadmin
新密码：<gpadmin>
重新输入新密码：<gpadmin>

切换到 gpadmin用户并对 gpadmin 用户为该服务器生成SSH密钥。

$ su gpadmin 
$ ssh-keygen -t rsa
$ ssh-copy-id aivmp-bigdata0001
$ ssh-copy-id aivmp-bigdata0002
$ ssh-copy-id aivmp-bigdata0003
$ ssh-copy-id ecs-application0002

（可选）对 gpadmin 用户授予sudo权限。

# visudo 
.....
root    ALL=(ALL)       ALL
gpadmin ALL=(ALL)       ALL
.....

添加 gpadmin 用户到此分组。
```
usermod -aG wheel gpadmin
```

安装数据库到每台机器

下载安装

wget https://github.com/greenplum-db/gpdb/releases/download/6.14.1/open-source-greenplum-db-6.14.1-rhel7-x86_64.rpm && yum install open-source-greenplum-db-6.14.1-rhel7-x86_64.rpm -y

授予权限给gpadmin用户

sudo chown -R gpadmin:gpadmin /usr/local/greenplum*
sudo chgrp -R gpadmin /usr/local/greenplum*

添加环境变量为gpadmin

$ cat > /home/gpadmin/.bashrc<< EOF
# .bashrc

if [ -f /etc/bashrc ]; then
        . /etc/bashrc

创建文件夹

# mkdir -p /data/master
# chown -R gpadmin:gpadmin /data/master

创建gpinitsystem_config文件

注意：declare -a DATA_DIRECTORY和declare -a MIRROR_DATA_DIRECTORY必须是成对出现得。里面几个文件夹，就代表一个segment机器上面启动了几个实例。一般推荐每台机器上启动2~4个实例，最大化cpu利用。

mkdir -p data/mirror
mkdir -p data/master

初始化

正常的初始化

$ gpinitsystem -c gpinitsystem_config

带有Standby节点：

Standby节点必须能ssh到所有机器，其他配置和master保持完全一致，同样需要提前建立data/master/文件夹。

$ gpinitsystem -c  gpinitsystem_config -s aivmp-bigdata0001

如果初始化得时候没有做Standby，那就在集群正常运行得时候，在master节点运行gpinitstandby命令完成新增Stanby节点

$ gpinitstandby -s aivmp-bigdata0001

不成功了删除Stanby产生得脏数据，排错，从新建立Standby节点

$ rm -rf /home/gpadmin/data/master/*

初始化失败后，清楚数据，清楚日志，并重新初始化

# rm -rf  /home/gpadmin/data/master/* /home/gpadmin/data/primary/* /home/gpadmin/data/mirror/* /home/gpadmin/gpAdminLogs /tmp/*

# rm -rf  /data/master/* /data/primary/* /data/mirror/* /home/gpadmin/gpAdminLogs /tmp/*

# rm -rf  /home/gpadmin/data /home/gpadmin/gpAdminLogs /tmp/*
