把编译好的放到
/usr/local/greenplum-db
这个greenplum我这里是用上面用源码编译好的文件，也可以用官网上的商业版本下载安装，都一样，出来greenplum目录后再执行下面的**

安装python所需包
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
pip install setuptools
pip install --upgrade setuptools
pip install epydoc psi psutil lockfile paramiko conan
#安装conan的时候遇到 Cannot uninstall ‘pyparsing’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall. 意思是卸载不了这个，要手动人来来，解决办法是用
yum remove pyparsing
.又遇到Cannot uninstall ‘enum34’. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.解决办法是
yum remove python-enum34
各机器上
root下加用户
groupadd -g 3030 gpadmin
useradd -u 3030 gpadmin -g gpadmin -d /home/gpadmin
passwd gpadmin
配置内核参数，添加如下内容
[root@xxx]#vi /etc/sysctl.conf
#By greenplum
net.ipv4.ip_forward = 0
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 1
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.sem = 250 64000 100 512
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sem = 250 64000 100 512
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_max_syn_backlog=4096
net.core.netdev_max_backlog=10000
vm.overcommit_memory=2
net.ipv4.conf.all.arp_filter = 1
手工执行命令，让参数生效
[root@xxx]# sysctl -p
在limits.conf文件中添加如下配置
[root@xxx]#vi /etc/security/limits.conf
- soft nofile 65536
- hard nofile 65536
- soft nproc 131072
- hard nproc 131072
调整IO调度算法 修改内核参数，添加如下配置，调整IO调度算法：（重启系统才能生效）
[root@xxx]#vi /boot/grub/menu.lst
elevator=deadline
设置磁盘预读，优化磁盘IO效率（重启系统才能生效）
[root@xxx]#vi /etc/rc.d/rc.local
blockdev --setra 16384 /dev/sd*
防火墙设置
用户可以详细配置系统防火墙允许的端口，由于 Greenplum 使用到的端口较多，这里选择关闭。
systemctl stop firewalld
systemctl disable firewalld
su root
vi /etc/hosts
192.168.137.202 mdw
192.168.137.203 sdw1
vi /etc/hostname
mdw
从机上就写 sdw1
reboot
回mdw机上
su gpadmin
cd ~
vi all_hosts
mdw
sdw1
vi seg_hosts
sdw1
建立文件夹并赋权
su root
mkdir -p /tol/master
chown -R gpadmin:gpadmin /tol/master
从机上
mkdir -p /tol/data/gp1
mkdir -p /tol/data/gp2
chown -R gpadmin:gpadmin /tol/data/gp*
主机上
修改 .bash_profile 文件 注意所有节点都需要建立此文件并执行后才能执行 gpinitsystem -c gpinitsystem_config 这是非常重要的步骤！
su gpadmin
cd ~
vi .bash_profile
source /usr/local/greenplum-db/greenplum_path.sh
export MASTER_DATA_DIRECTORY=/tol/master/gpseg-1
export PGPORT=5432
export PGUSER=gpadmin
export PGDATABASE=gpdb1
source .bash_profile
建立节点信任 如果不行（这个搞了好久有问题）就自己手动免密（这个手动免密在另一篇文章）
gpssh-exkeys -f all_hosts
各机器上把缺少的那些包（这只有源码编译的才需要）
复制到/usr/local/lib目录下
打开 /usr/local/greenplum-db/greenplum_path.sh 找到LD_LIBRARY_PATH ，给它加上/usr/local/lib: 表示这个lib里的包也加载
这里用root 改权限
chown -R gpadmin:gpadmin /usr/local/green*
chmod 777 /usr/local/greenplum-db/sbin/*
chmod 777 /usr/local/greenplum-db/bin/lib/*
chmod 777 /usr/local/greenplum-db/bin/*
su gpadmin
cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config .
修改 gpinitsystem_config 文件
vi gpinitsystem_config
declare -a DATA_DIRECTORY=(/tol/data/gp1 /tol/data/gp2)
MASTER_HOSTNAME=mdw
MASTER_DIRECTORY=/tol/master
DATABASE_NAME=gpdb1
MACHINE_LIST_FILE=/home/gpadmin/seg_hosts
初始化
gpinitsystem -c gpinitsystem_config
安装完毕后数据库初始设置
安装结束后可以连接GP数据库了：
[gpadmin@xxx]$ psql -d gpdb1
psql (8.2.15)
Type “help” for help.
goolen=# \q
初始设置, 设置密码
psql -h mdw -p 5432 -d gpdb1 -U gpadmin
alter role gpadmin with password ‘gpadmin’;
gpstart failed. (Reason=‘Environment Variable MASTER_DATA_DIRECTORY not set!’) exiting…
启动如果报目录没设置就执行下
source .bash_profile
如果用pgadmin不能连接，提示拒绝，就要在master机上
/tol/master/gpseg-1 里的pg_hba.conf 加上
host all all 0.0.0.0/0 md5
这是所有的，可以按需要加入某个ip，改完后执行下面更新配置
pg_ctl reload -D /tol/master/gpseg-1/
查询数据分布情况
select gp_segment_id, count(*) from user_test group by gp_segment_id;
