greenplum安装教程

2023-03-17 00:00:00 创建 修改 用户 节点 添加

1. 系统参数配置(在所有节点服务器上执行)

1.1修改Linux内核参数

[root@master ~]# vim /etc/sysctl.conf

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

kernel.msgmni= 2048

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.ip_local_port_range= 1025 65535

net.core.netdev_max_backlog= 10000

net.core.rmem_max= 2097152

net.core.wmem_max= 2097152

vm.overcommit_memory = 2

1.2 修改Linux大限制(在limits.conf后添加如下几行)

[root@master ~]# vim /etc/security/limits.conf

#greenplumconfigs

* softnofile 65536

* hardnofile 65536

* softnproc 131072

*hard nproc 131072

1.3 I/O调整优化(在menu.lst后添加)

[root@master~]# vim /boot/grub/menu.lst

#greenplumconfigs

elevator=deadline

1.4 添加所有节点到host

[root@master ~]# vim /etc/hosts

10.139.*.* master

10.139.*.* seg1

10.139.*.* seg2

10.139.*.* seg3

注:修改主机名的方法如下:

1). 修改/etc/sysconfig下的network文件

[root@master~]# vim /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=master

2)重启(reboot)生效

在所有的服务器上安装ed包(本人选择包名如下)

执行如下命令:rpm –ivh ed-1.1-3.3.el6.x86_64.rpm

1.5 关闭防火墙

1.5.1 查看防火墙状态:[root@master ~]# service iptables status

结果为:iptables:未运行防火墙。(表示防火墙已经关闭)

1.5.2 关闭防火墙:[root@master ~]# chkconfig iptables off (重启后生效)

即时生效:[root@master ~]# service iptables stop-

1.6 设置selinux

[root@master ~]# vim/etc/selinux/config

SELINUX=disabled

2. master主机上安装gp(使用root用户)

2.1. 创建gpadmin用户(在全部服务器节点上创建)

[root@master~]# useradd gpadmin

[root@master~]# passwd gpadmin

2.2 使用root用户安装gp(只在master上运行)

[root@master ~]# unzip/tmp/gp/greenplum-db-4.3.9.0-build-1-RHEL5-x86_64.zip

[root@master ~]#/bin/bashgreenplum-db-4.2.2.4-build-1-CE-RHEL5-i386.bin

2.3 创建all_host和all_segment文件

1) 创建文件夹:[root@master~]# mkdir -p /opt/gpinit/

2) 创建all_host和all_segment文件,分别添加如下内容:

all_host

all_segment

master

seg1

seg2

seg3

seg1

seg2

seg3


3) 改变all_host和all_segment所属主和所属组  

[root@master gpinit]# chown -Rgpadmin:gpadmin /opt/

2.4 使用gpadmin用户交换秘钥(也可以使用root用户,交换root用户秘钥):

1).导入gp工具环境变量:[root@master~]# source /home/gpadmin/.bashrc

2). 交换秘钥:[gpadmin@mastergpinit]$ gpssh-exkeys -f /opt/gpinit/all_hosts(需要创建目录时,需要手动创建)

3).批量安装(gpadmin用户):

3.1). 压缩安装的gp:(位于/usr/local/目录下)

[root@master local] tar -cfgreenplum-db-4.3.9.0.tar greenplum-db-4.3.9.0

[root@master local] chowngpadmin:gpadmin greenplum-db-4.3.9.0.tar

可能需要的步骤:[root@master local] gzip greenplum-db-4.3.9.0.tar

[root@master local] tar -cfgreenplum-db-4.3.9.0.tar greenplum-db-4.3.9.0

[root@master local] tar -cfgreenplum-db-4.3.9.0.tar greenplum-db-4.3.9.0

[gpadmin@bj-gp-node1 local]# gpseginstall-f /opt/gpinit/all_segment -u gpadmin -p 123456

4).检查是否批量安装成功:[gpadmin@mastergpinit]$ gpssh -f all_host -e ls -l $GPHOME

返回结果中各节点目录一致则成功

2.5 检查系统配置

执行以下命令:gpcheckos -f /opt/gpinit/all_hosts

根据错误信息修改/etc/sysctl.conf(以root身份来改)

错误信息中没有的,直接添加即可(添加时删除前面的sysctl)



3. 创建存储目录

1) master节点

[root@master ~]# mkdir -p /gp/data1/gpdata/primary

[root@master ~]# chown -R gpadmin:gpadmin /gp/

2) segment节点(需要先手动在各节点创建/gp/目录)

[gpadmin@master ~]#gpssh -f /opt/gpinit/all_segment -e 'mkdir -p /gp/data1/gpdata/primary/'

3) mirror目录

[gpadmin@master ~]#gpssh -f /opt/gpinit/all_segment -e 'mkdir -p /data1/gpdata/mirror'

4. 设置时钟同步

vim /etc/ntp.conf 在server行添加下面几行行(在所有的服务器节点上添加)

master节点:server127.127.1.0

sgement节点:server wggh_1prefer

重启ntpd服务/etc/init.d/ntpd restart

查看ntp同步情况 ntpq -p

使ntpd服务重启服务器后也启动chkconfig --level 0123456 ntpd on

5. 创建GP初始化文件

[gpadmin@master ~]$ mkdir /home/gpadmin/gpconfigs

[gpadmin@master ~]$cp /usr/local/greenplum-db/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/gpconfigs/gpinitsystem_config

[gpadmin@tj-soc-c04-csfb1gpconfigs]$ chmod 775 gpinitsystem_config

6. 修改gp初始化文件

[gpadmin@mastergpconfigs]$ vi gpinitsystem_config





# FILENAME: gpinitsystem_config



#Configuration file needed by the gpinitsystem

####OTHER OPTIONAL PARAMETERS

################################################



####Create a database of this name after initialization.

DATABASE_NAME=bj_gp



####Specify the location of the host address file here instead of

#### withthe the -h option of gpinitsystem.

#MACHINE_LIST_FILE=/home/gpadmin/gpconfigs/hostfile_gpinitsystem



7 初始化gp

[gpadmin@master~]$ gpinitsystem -c /home/gpadmin/gpconfigs/gpinitsystem_config -h/opt/gpinit/all_host

中间需要输入一次:Y

注:数据目录有错误时,需要修改。如果没有报ERROR,GP数据库就安装好了

8 增加standby

一个gp集群只有一个master肯定会让人不放心,还好有备用,当master宕掉后,会自动启用standby作为master,下面来看一下standby怎么添加.

在standby服务器上执行

[root@seg1 ~]#mkdir /data1/gpdata/master

[root@seg1 ~]#chown gpadmin:gpadmin /data1/gpdata/master



在master服务器上执行 

[gpadmin@master~]$ gpinitstandby -s seg2

中间输入一次Y
