基本环境：

server IP
MDW 172.16.16.31
SDW1 172.16.16.34
SDW2 172.16.16.35
1：检查操作系统是否符合要求，以及系统设置。

我这里使用的系统是CentOS ,操作系统要求CentOS64-bit 6.x or 7.x，CentOS最好是7以上版本。 然后关闭selinux，iptables

  1. cat  /etc/selinux/config
  2. SELINUX=disabled

　　

查看状态：

  1. [root@16-31 mail]# sestatus
  2. SELinux status:                 disabled

　　

关闭iptables

  1. [root@16-31 ~]# chkconfig iptables off
  2. [root@16-31 ~]# chkconfig --list |grep iptables
  3. iptables       	0:off	1:off	2:off	3:off	4:off	5:off	6:off

　　

配置系统参数，官方给出了一些建议的配置：

  1. vi /etc/sysctl.conf

　　

然后修改

  1. kernel.shmmax = 500000000
  2. kernel.shmmni = 4096
  3. kernel.shmall = 4000000000
  4. kernel.sem = 250 512000 100 2048
  5. kernel.sysrq = 1
  6. kernel.core_uses_pid = 1
  7. kernel.msgmnb = 65536
  8. kernel.msgmax = 65536
  9. kernel.msgmni = 2048
  10. net.ipv4.tcp_syncookies = 1
  11. net.ipv4.conf.default.accept_source_route = 0
  12. net.ipv4.tcp_tw_recycle = 1
  13. net.ipv4.tcp_max_syn_backlog = 4096
  14. net.ipv4.conf.all.arp_filter = 1
  15. net.ipv4.ip_local_port_range = 10000 65535
  16. net.core.netdev_max_backlog = 10000
  17. net.core.rmem_max = 2097152
  18. net.core.wmem_max = 2097152
  19. vm.overcommit_memory = 2

　　

第二个文件也有一些需要修改的地方

  1. vi /etc/security/limits.conf

　　

添加以下内容：

  1. * soft nofile 65536
  2. * hard nofile 65536
  3. * soft nproc 131072
  4. * hard nproc 131072

　　

修改IO调度算法：

  1. echo deadline > /sys/block/sr0/queue/scheduler

　　

然后重启机器。文件系统最好使用XFS。 禁用THP：

  1. [root@16-31 ~]# grubby --update-kernel=ALL --args="transparent_hugepage=never"
  2. [root@16-31 ~]#  cat /sys/kernel/mm/*transparent_hugepage/enabled
  3. [always] madvise never
  4. [always] madvise never

　　

2：安装Greenplum

我们下载的是5.0版本，使用二进制发行版安装，使用root用户登录，最好建立一个单独的用户进行安装。 所有节点创建用户

  1. useradd  gpadmin

　　

先进行解压：

  1. [root@16-31 sa]# unzip  greenplum-db-5.0.0-rhel7-x86_64.zip
  2. [root@16-31 gptest]# groupadd gpadmin
  3. [root@16-31 gptest]# useradd -r -g gpadmin -s /bin/false gpadmin

　　

开始安装：

  1. [root@16-31 gptest]# /bin/bash  greenplum-db-5.0.0-rhel7-x86_64.bin

　　

安装过程会有提示：

安装以后的我们进去看一下具体的安装目录：

  1. [root@16-31 greenplum-db-5.0.0]# ls
  2. bin  docs  etc  ext  greenplum_path.sh  include  lib  pxf  sbin  share

　　

看看目录具体作用：

  1. greenplum_path.sh：配置文件
  2. bin目录：主要是一些工具，其中也包括pgsql等
  3. docs目录：帮助文件和一些配置文件
  4. etc:示例配置文件和一些工具的配置文件
  5. ext：GP的一些绑定程序，我们看到现在只有一个python
  6. include：GP的一些C的头文件
  7. lib：库文件
  8. sbin：内部脚本和程序
  9. share ：共享文件夹

　　

然后我们在另外两台机器上也执行相同脚本进行安装和部署或者使用gpseginstall进行安装。这里我们使用第二种方法 先修改host文件：

  1. 172.16.16.31	mdw
  2. 172.16.16.34	sdw1
  3. 172.16.16.35	sdw2

　　

初始化一下环境变量，这里我们可以看到两个

  1. [root@mdw greenplum-db-5.0.0]# source /home/greenplum-db-5.0.0/greenplum_path.sh
  2. [root@mdw greenplum-db-5.0.0]# source /home/greenplum-db/greenplum_path.sh

　　

两个文件是一模一样的选择任何都是一样的。然后创建一个文件：

  1. [root@16-31 greenplum-db-5.0.0]# cat my_host_list_file
  2. mdw
  3. sdw1
  4. sdw2

　　

配置SSH的免密链接：

  1. [gpadmin@mdw sa]$ gpssh-exkeys -f /home/gpdb/hostlist
  2. [STEP 1 of 5] create local ID and authorize on local host
  3.  
  4. [STEP 2 of 5] keyscan all hosts and update known_hosts file
  5.  
  6. [STEP 3 of 5] authorize current user on remote hosts
  7.   ... send to sdw1
  8.   ***
  9.   *** Enter password for sdw1:
  10.   ... send to sdw2
  11.  
  12. [STEP 4 of 5] determine common authentication file content
  13.  
  14. [STEP 5 of 5] copy authentication files to all remote hosts
  15.   ... finished key exchange with sdw1
  16.   ... finished key exchange with sdw2
  17.  
  18. [INFO] completed successfully

　　

在各个节点创建所必须的文件夹：

  1. [gpadmin@mdw sa]$ gpssh -f /home/gpdb/seghostlist -e -v 'sudo mkdir -p  /home/greenplum && sudo chown -R gpadmin /home/greenplum'
  2. [WARN] Reference default values as $MASTER_DATA_DIRECTORY/gpssh.conf could not be found
  3. Using delaybeforesend 0.05 and prompt_validation_timeout 1.0

  10. [INFO] completed successfully

然后给这个账号暂时赋予管理员的权限：

  1. [root@mdw ~]# visudo
  2. gpadmin    ALL=(ALL)       ALL
  3. gpadmin    ALL=(ALL)       NOPASSWD:ALL

　　

安装完成以后我们检查一下安装：

  1. [gpadmin@mdw home]$ gpssh -f /home/gpdb/seghostlist -e ls -l $GPHOME
  2. [sdw1] ls -l /home/greenplum/greenplum-db/.
  3. [sdw1] total 40

  25. [sdw2] drwxr-xr-x 5 gpadmin root 4096 Sep  8 04:59 share

　　

接下来我们创建数据目录的空间：

  1. [gpadmin@mdw home]$ cd greenplum/
  2. [gpadmin@mdw greenplum]$ ls
  3. greenplum-db  greenplum-db-5.0.0
  4. [gpadmin@mdw greenplum]$ source /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh
  5. [gpadmin@mdw greenplum]$ gpssh -f /home/gpdb/hostlist -e 'mkdir -p /home/greenplum/data'
  6. [sdw1] mkdir -p /home/greenplum/data
  7. [sdw2] mkdir -p /home/greenplum/data
  8. [ mdw] mkdir -p /home/greenplum/data
  9. [gpadmin@mdw greenplum]$ gpssh -h mdw  -e 'mkdir -p /home/greenplum/data/master'
  10. [mdw] mkdir -p /home/greenplum/data/master
  11. [gpadmin@mdw greenplum]$ gpssh -f /home/gpdb/seghostlist -e 'mkdir -p /home/greenplum/data/{primary,mirror}'
  12. [sdw1] mkdir -p /home/greenplum/data/{primary,mirror}
  13. [sdw2] mkdir -p /home/greenplum/data/{primary,mirror}

　　

设置环境变量：

  1. [gpadmin@sdw1 data]$ cat /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh >>/home/gpadmin/.bash_profile
  2. [gpadmin@sdw1 data]$ source /home/gpadmin/.bash_profile
  3. [gpadmin@sdw1 data]$ gps
  4. gpscp            gpseginstall     gpsourcify.pl    gpssh-exkeys     gpstate          gpstringsubs.pl

  6.  
  7. [gpadmin@mdw .ssh]$ cat   /home/greenplum/greenplum-db-5.0.0/greenplum_path.sh>> ~/.bashrc
  8. [gpadmin@mdw .ssh]$ scp  ~/.bashrc  sdw1:~
  9. .bashrc                                                                                                                                                    100%  969     1.0KB/s   00:00
  10. [gpadmin@mdw .ssh]$ scp  ~/.bashrc  sdw2:~
  11. .bashrc

　　

同步时钟： 在Master主机上编辑/etc/ntp.conf来设置如下内容： server 127.127.1.0 在Segment主机上编辑/etc/ntp.conf server mdw

  1. [root@mdw ntp]# su gpadmin

上面的都完成以后，我们来开始初始化GP之前的检查：

  1. [root@mdw queue]# su gpadmin
  2. [gpadmin@mdw queue]$ gpcheck -f /home/gpdb/hostlist -m mdw
  3. Cannot import modules.  Please check that you have sourced greenplum_path.sh.  Detail: No module named gppylib.gpparseopts

  14. 下面开始初始化数据库，首先我们创建配置文件：
  15.  
  16. [gpadmin@mdw ~]$ cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config   /home/gpadmin/gpinitsystem_config
  17. [gpadmin@mdw ~]$ ls
  18. gpAdminLogs  gpinitsystem_config
  19. [gpadmin@mdw ~]$ chmod 775 gpinitsystem_config
  20. [gpadmin@mdw ~]$ vi gpinitsystem_config

　　

配置文件如下：

  1. ARRAY_NAME="Greenplum Data Platform"
  2. SEG_PREFIX=gpseg
  3. PORT_BASE=40000
  4. declare -a DATA_DIRECTORY=(/home/greenplum/data/primary /home/greenplum/data/primary)
  5. MASTER_HOSTNAME=mdw
  6. MASTER_DIRECTORY=/home/greenplum/data/master
  7. MASTER_PORT=5432
  8. TRUSTED_SHELL=ssh
  9. CHECK_POINT_SEGMENTS=8
  10. ENCODING=UNICODE
  11. declare -a MIRROR_DATA_DIRECTORY=(/home/greenplum/data/mirror /home/greenplum/data/mirror)
  12. MACHINE_LIST_FILE=/home/gpdb/seghostlist

　　

下面就开始初始化数据库吧：

  1. [gpadmin@mdw ~]$ gpinitsystem -c gpinitsystem_config -h /home/gpdb/seghostlist

看到已经是初始化成功了，从库也是。在master上登录数据库看一下：

　　OK，算是安装成功。

在这里，我们可以看到我们两个segment节点我们起了四个节点，现在我们为每个segment节点添加一个mirror节点。

我们进入GP查看一下：

添加成功。

最后我们还要贴一下mirror的配置文件：

  1. [gpadmin@mdw greenplum-db]$ cat //home/gpadmin/gp_mirror_config
  2. filespaceOrder=
  3. mirror0=0:sdw2:52001:53001:54001:/home/greenplum/data/mirror/gp0
  4. mirror1=1:sdw2:52002:53002:54002:/home/greenplum/data/mirror/gp1
  5. mirror2=2:sdw1:52001:53001:54001:/home/greenplum/data/mirror/gp2
  6. mirror3=3:sdw1:52002:53002:54002:/home/greenplum/data/mirror/gp3
