virtualbox 安裝greenplum

安裝步驟總結：
 1.準備安裝環境
  下載virtualbox 和 centos 5.5
  安裝centos，然後利用匯出，匯入虛擬出三臺主機(1臺master 兩臺segment),此過程注意網路設定中更改mac地址
 2.在master主機上配置ntp協議。
 3.用root使用者拷貝安裝介質並解壓
 4.利用gpssh-exkeys 工具交換金鑰(在此步驟，使用centos6.0時報錯)
 5.配置master環境變數主要包括(/etc/sysctl.conf,/etc/security/limits.conf,/etc/hosts)
 6.編輯seg_hosts和all_hosts檔案
 7.使用gpshh工具同步配置，同步安裝介質。
 8.編輯gpinitsystem_config檔案。
 9.初始化系統。
 10.配置pg_hba.conf postgresql.conf 檔案
安裝中注意事項
 1.關閉不必要的服務
 2.在配置虛擬機器的時候需採用centos 5.5 作業系統。
工具介紹
 gpssh 系列工具可以同時在多個主機上執行命令，複製命令。。。
 chkconfig --level 345 iptables off 關閉iptables 更改啟動服務
 service iptables stop|start|restart 停止|啟動|重啟 iptables 服務 
 mount 可以載入網路共享資料夾
 
詳細安裝過程

備註：對於環境的搭建，可以採用先安裝好一臺主機後利用虛擬機器匯入，匯出功能，虛擬其他主機(此過程中需要注意IP設定)
配置IP
vi /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
HWADDR="08:00:27:BF:91:4F"
NM_CONTROLLED="yes"
ONBOOT="yes"
BOOTPROTO=static
IPADDR=136.5.66.32
NETMASK=255.255.255.0
GATEWAY=136.5.66.9

注意  HWADDR 一定要與虛擬機器上一致
配置dns
vi /etc/resolv.conf
nameserver 61.128.128.68

--重啟
/etc/init.d/network restart

配置作業系統名稱(更改配置檔名稱)
vi /etc/sysconfig/network

環境：centos 5.5 (在用centos 6.0 時執行gpssh-extkeys 時報錯問題始終無法解決所以就更改為centos 5.5)
配置：1024G 記憶體 1 cpu 8G 硬碟
IP設定
gmaster 136.5.66.32
gseg1 136.5.66.33
gseg2 136.5.66.34

宿主機 136.5.66.29

系統準備：
1  在master 上安裝 ntp服務(保證所有節點與master時間同步)
 yum install ntp
 vi /etc/ntp.conf
 #server 127.127.1.0     # local clock
 server  127.127.1.0     # local clock
 #fudge  127.127.1.0 stratum 10
 fudge   127.127.1.0 stratum 10
 新增 日誌目錄
 statsdir /var/log/ntp
 logfile  /var/log/ntp/ntp.log

　　啟動NTPD
    為了使NTP服務可以在系統引導的時候自動啟動，執行：
    chkconfig --level 345 ntpd on
    啟動ntpd：
　　service ntpd start
 關閉防火牆
 chkconfig --level 345 iptables off
 service iptables stop

 在客戶機上編輯同步指令碼(注意執行 chmod 777 /usr/local/bin/ntprsync.sh)
 [[email protected] ~]# cat /usr/local/bin/ntprsync.sh
 #!/bin/sh

 /usr/sbin/ntpdate 136.5.66.32
 /sbin/hwclock -w
 每日同步
 [[email protected] ~]# crontab -l
 #rsync time
 0 0 1 * * /usr/local/bin/ntprsync.sh
2 安裝unzip 工具
 yum install unzip

安裝步驟：
1.傳送安裝介質
 1) 在宿主機上共享安裝介質，其共享目錄為share
 2) 以root使用者登入master
 3) mkdir -p /mnt/share
 4) mount -t cifs -o username=liuhb,password=liuhb520 //136.5.66.29/share /mnt/share
2.建立安裝使用者(此步驟可以在使用gpssh統一建立)
 以root使用者登入master
 useradd gpadmin (建立使用者)
 passwd gpadmin  (設定密碼)
3.拷貝介質
 以gpadmin登入master
 cp /mnt/share/* ./  (拷貝到本使用者下)
 chmod u+x greenplum-db-4.1.1.1-build-1-RHEL5-i386.bin  (更改執行許可權)
4.解壓檔案
 以root 登入master
 ./greenplum-db-4.1.1.1-build-1-RHEL5-i386.bin  (根據提示直接輸入預設值)
 cd /usr/local
 chown -R gpadmin:gpadmin greenplum*     (賦予gpadmin 許可權)
 su - gpadmin
 chmod +x /usr/local/greenplum-db/greenplum_path.sh
 vi ~/.bashrc (新增 source /usr/local/greenplum-db/greenplum_path.sh) 
 . ~/.bashrc
5.配置ssh等效性(用root使用者登入)
 1)編輯/etc/hosts
 [[email protected] greenplum-db]# cat /etc/hosts
 127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
 ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

 136.5.66.32     gmaster

 136.5.66.33     gseg1
 136.5.66.34     gseg2
 2)匯入gp工具環境變數  source /usr/local/greenplum-db/greenplum_path.sh
 3)編輯all_hosts
 [[email protected] allssh]# cat all_hosts
 gmaster
 gseg1
 gseg2
  編輯seg_hosts
 [[email protected] allssh]# cat seg_hosts
 gseg1
 gseg2 
 4)gpssh-exkeys -f all_hosts
6.設定系統變數

In /etc/sysctl.conf:

kernel.sem = 250 64000 100 512
kernel.shmmax = 500000000
kernel.shmmni = 4096
kernel.shmall = 4000000000
kernel.sem = 250 64000 100 512
kernel.sysrq = 1
kernel.core_uses_pid = 1
kernel.msgmnb = 65536
kernel.msgmax = 65536
net.ipv4.tcp_syncookies = 1
net.ipv4.ip_forward = 0
net.ipv4.conf.default.accept_source_route = 0
net.ipv4.tcp_tw_recycle=1
net.ipv4.tcp_max_syn_backlog=4096
net.ipv4.conf.all.arp_filter = 1
net.ipv4.conf.default.arp_filter = 1
net.core.netdev_max_backlog=10000
vm.overcommit_memory=2

In /etc/security/limits.conf:

* soft nofile 65536 
* hard nofile 65536 
* soft nproc 131072
* hard nproc 131072

sysctl -p

 定義hosts並拷貝到其他主機
 gpscp -f seg_hosts /etc/hosts =:/etc
 gpscp -f seg_hosts /etc/security/limits.conf =:/etc/security
 gpscp -f seg_hosts /etc/sysctl.conf =:/etc
 
 gpssh -f seg_hosts
 =>sysctl -p
 
5.批量設定使用者
 gpssh -f all_hosts
 groupadd -g 3030 gpadmin
 useradd -u 3030 -g gpadmin -d /home/gpadmin -s /bin/bash -m gpadmin
 passwd gpadmin
 chown -R gpadmin:gpadmin /usr/local/greenplum-db
 關掉不必要的服務
echo 'console=ttyS0 9600' >> /boot/grub/grub.conf
echo 'S1:12345:respawn:/sbin/agetty -L 9600 ttyS0 vt102' >> /etc/inittab
echo 'ttyS1' >> /etc/securetty
service ipmi start
chkconfig ipmi on
service iptables save 
service iptables stop 
chkconfig iptables off
service ip6tables save
service ip6tables stop
chkconfig ip6tables off
chkconfig avahi-daemon off
chkconfig avahi-dnsconfd off
chkconfig conman off
chkconfig bluetooth off
chkconfig cpuspeed off
chkconfig setroubleshoot off
chkconfig hidd off
chkconfig hplip off
chkconfig isdn off
chkconfig kudzu off
chkconfig yum-updatesd

 
 7.初始化系統
 用gpadmin 登入
 mkdir gpconfigs
 cd gpconfigs
 cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config ./
 更改配置檔案
 gpinitsystem -c gpinitsystem_config -h hostfile_gpinitsystem
 
 [[email protected] gp]# gpssh -f all_hosts
=> mkdir -p /data1/primary
[  gseg2]
[  gseg1]
[gmaster]
=> mkdir -p /data2/primary
[  gseg2]
[  gseg1]
[gmaster]
=> chown -R gpadmin:gpadmin /data2/primary
[  gseg2]
[  gseg1]
[gmaster]
=> chown -R gpadmin:gpadmin /data1/primary
[  gseg2]
[  gseg1]
[gmaster]
=>
8.系統正式安裝
 gpinitsystem -c gpinitsystem_config -h hostfile_gpinitsystem   (如果出現輸入密碼,需要交換金鑰 gpssh-exkeys -f all_hosts )
  
 [[email protected] gpconfigs]$ gpssh-exkeys -f all_hosts

 執行 gpssh-exkeys -f all_hosts  時報錯
[[email protected] allssh]# gpssh-exkeys -f all_hosts
