首先说一下,无论是CentOS/RedHat还是Ubuntu都可以按源码方式、安装包方式编译安装。

 

 

1.   规划

192.168.4.93(h93)       1个主master  2个主segment、2个镜像segment

192.168.4.94(h94)       1个备master  2个主segment、2个镜像segment

都安装在/home/wslu/gp/gpsql目录。

 

2.   安装依赖

在h93和h94安装以下依赖:

2.1.  Ubuntu

 

[python]   
 
  1. apt-get install -y git-core  
  2. apt-get install -y gcc g++  
  3. apt-get install -y ccache  
  4. apt-get install -y libreadline-dev  
  5. apt-get install -y bison flex  
  6. apt-get install -y zlib1g-dev

  12. apt-get install -y ssh  
  13.    
  14. apt-get install -y libcurl4-dev  
  15. Package libcurl4-dev is a virtual package provided by:  
  16. libcurl4-openssl-dev 7.38.0-4+deb8u2  
  17. libcurl4-nss-dev 7.38.0-4+deb8u2

  19.    
  20. apt-get install -y python-pip  
  21.    
  22. pip install lockfile  
  23. pip install paramiko  
  24. pip install setuptools  
  25. pip install epydoc  
  26. pip install psi  
  27. Note: debian8 required pip install --pre psi  

 

2.2.  Centos

yum源要按照我的总结中的设置。

 

[python]   
 
  1. yum install –y git.x86_64  
  2. yum install –y gcc.x86_64 gcc-c++.x86_64  
  3. yum install –y ccache.x86_64  
  4. yum install readline.x86_64 readline-devel.x86_64  
  5. yum install bison.x86_64 bison-devel.x86_64  
  6. yum install flex.x86_64 flex-devel.x86_64  
  7. yum install zlib.x86_64 zlib-devel.x86_64  
  8. yum install -y openssl.x86_64 openssl-devel.x86_64  
  9. yum install -y pam.x86_64 pam-devel.x86_64  
  10. yum install –y libcurl.x86_64 libcurl-devel.x86_64  
  11. yum install bzip2-libs.x86_64 bzip2.x86_64 bzip2-devel.x86_64  
  12. yum install libssh2.x86_64 libssh2-devel.x86_64  
  13. yum install python-devel.x86_64  
  14. yum install -y python-pip.noarch  
  15.    
  16. 接着执行:  
  17. pip install lockfile  
  18. pip install paramiko  
  19. pip install setuptools  
  20. pip install epydoc  
  21. pip install psi  
  22. 或者执行:  
  23. yum install python-lockfile.noarch  
  24. yum install python-PSI.x86_64  
  25. yum install python-paramiko.noarch  
  26. yum install python-setuptools.noarch  
  27. yum install epydoc.noarch  

 

3.   源码安装

3.1.  克隆源码

在h93和h94执行:

 

[python]   
 
  1. $ mkdir /home/wslu/gp/greenplum  
  2. $ cd /home/wslu/gp/greenplum  
  3. $ git clone https://github.com/greenplum-db/gpdb.  

 

3.2.  编译安装

在h93和h94执行:

 

[python]   
 
  1. $ cd /home/wslu/gp/greenplum  
  2. $ CFLAGS+="-O2" ./configure--prefix=/home/wslu/gp/gpsql --enable-debug --enable-depend --enable-cassert  
  3. $ make  
  4. $ make install  

安装时如果遇到某些python包(lockfile、 paramiko、PSI等)找不到,可以参考HAWQ, (源码https://github.com/apache/incubator-hawq)<hawq_src>/tools/bin/pythonSrc/ 下所有的压缩包拷贝到/home/wslu/gp/greenplum/gpMgmt/bin/pythonSrc/ext/ 中,然后再make install即可。

至此集群源码编译完成。

 

4.   安装包安装

下载greenplum-db-4.3.6.1-build-2-RHEL5-x86_64.zip

 

[python]   
 
  1. $ unzip greenplum-db-4.3.6.1-build-2-RHEL5-x86_64.zip  

 

在h93和h94使用普通用户安装:

 

[python]   
 
  1. $./greenplum-db-4.3.6.1-build-2-RHEL5-x86_64.bin   

 

安装到 /home/wslu/gp/gpsql

 

5.   设置操作系统参数

在h93和h94执行下述设置:

5.1.  系统级参数配置

以下配置需要在root下进行配置,所以需要能够得到root权限。

首先是防火墙的设置:

 

[python]   
 
  1. service iptables status    #查看是否开启了防火墙  
  2. service iptables stop       #关闭防火墙  
  3. chkconfig iptables off      #设置开机不会启动防火墙  

 

其次是ssh的速度设置:

 

[python]   
 
  1. sed -i 's/^GSS/#&/g' /etc/ssh/sshd_config      #用来加速SSH连接的  
  2.   service sshd reload  

 

内核处理和内存方面的设置:

 

[python]   
 
  1. # 设置内核参数, 并在启动时生效  
  2. sysctl -p - >>/etc/sysctl.conf <<EOF  
  3. # configurations  
  4. kernel.sysrq=1  
  5. kernel.core_pattern=core  
  6. kernel.core_uses_pid=1  
  7. kernel.msgmnb=65536  
  8. kernel.msgmax=65536  
  9. kernel.msgmni=2048  
  10. kernel.sem=25600 3200000 10000 14200  
  11. net.ipv4.tcp_syncookies=1  
  12. net.ipv4.ip_forward=0  
  13. net.ipv4.conf.default.accept_source_route=0  
  14. net.ipv4.tcp_tw_recycle=1  
  15. net.ipv4.tcp_max_syn_backlog=4096  
  16. net.ipv4.conf.all.arp_filter=1  
  17. net.ipv4.ip_local_port_range=1025 65535  
  18. net.core.netdev_max_backlog=10000  
  19. net.core.rmem_max=2097152  
  20. net.core.wmem_max=2097152  
  21. vm.overcommit_memory=1  
  22. EOF  

如果配置集群时,因为要设置的共享内存大于系统最大共享内存而报错,则可以按照以下官方推荐的设置配置:

 

[python]   
 
  1. # vi /etc/sysctl.conf  
  2. kernel.shmmax = 500000000  
  3. kernel.shmmni = 4096  
  4. kernel.shmall = 4000000000  
  5. kernel.sem = 250 512000 100 2048  
  6. kernel.sysrq = 1   
  7. kernel.core_uses_pid = 1   
  8. kernel.msgmnb = 65536  
  9. kernel.msgmax = 65536  
  10. kernel.msgmni = 2048  
  11. net.ipv4.tcp_syncookies = 1   
  12. net.ipv4.ip_forward = 0   
  13. net.ipv4.conf.default.accept_source_route = 0   
  14. net.ipv4.tcp_tw_recycle = 1   
  15. net.ipv4.tcp_max_syn_backlog = 4096  
  16. net.ipv4.conf.all.arp_filter = 1   
  17. net.ipv4.ip_local_port_range = 1025 65535  
  18. net.core.netdev_max_backlog = 10000  
  19. net.core.rmem_max = 2097152  
  20. net.core.wmem_max = 2097152  
  21. vm.overcommit_memory = 2  

 

文件读写方面的设置:

 

[python]   
 
  1. # 设置limits  
  2. cat >>/etc/security/limits.d/99-kingbasedbcloud.conf <<EOF  
  3. #KingbaseDBCloud configurations  
  4. * soft nofile 65536  
  5. * hard nofile 65536  
  6. * soft nproc 131072  
  7. * hard nproc 131072  
  8. EOF  

 

 

5.2. 数据库级的参数设置

GUC参数设置,此设置需要按照实际机器来进行配置,常用的配置有如下几点:

 

[python]   
 
  1. work_mem=1GB  
  2. shared_buffers=2GB  
  3. max_connections=500  
  4. max_pool_size=2000  
  5. enable_mergejoin=off  
  6. enable_nestloop=off  
  7. max_prepared_transactions=50  
  8. autovacuum=off  
  9. interconnect_setup_timeout=1200  

 

 

6.   demo集群

安装完成后,就可以使用demo集群了。

执行下面命令即可在本机创建包含3个segment,3个segment-mirror,1个master的集群:

 

[python]   
 
  1. $ cd /home/wslu/gp/gpsql  
  2. $ source greenplum_path.sh  
  3. $ gpssh-exkeys –h localhost  
  4. $ cd gpAux/gpdemo  
  5. $ make cluster  
  6. $ source gpdemo-env.sh  

如果不想用demo集群,可以直接跳过本小节。

 

7.   设置环境变量

 

[python]   
 
  1. $ source gpsql/greenplum_path.sh  
  2. $ exportMASTER_DATA_DIRECTORY=/home/wslu/gp/gpsql/data/master/gpseg-1  

 

8.   交换key

在h93执行:

 

[python]   
 
  1. $ gpssh-exkeys –h h94  

 

         会提示输入h94的wslu用户的密码。(用户必须和h93相同)

则h93和h94之间可以无密码登陆了。

 

9. 初始化集群

(1)       在h93和h94执行下述指令,以创建数据目录:

 

[python]   
 
  1. $ mkdir gpsql/data/primary gpsql/data/mirror gpsql/data/master –p  

 

 

(2)       在h93创建配置文件configs/gpinitsystem_config,内容如下:

 

[python]   
 
  1. ARRAY_NAME="EMC Greenplum DW"  
  2. SEG_PREFIX=gpseg  
  3. PORT_BASE=40000  
  4. declare -a DATA_DIRECTORY=(/home/wslu/gp/gpsql/data/primary /home/wslu/gp/gpsql/data/primary)  
  5. MASTER_HOSTNAME=h93  
  6. MASTER_DIRECTORY=/home/wslu/gp/gpsql/data/master  
  7. MASTER_PORT=5432  
  8. TRUSTED_SHELL=ssh  
  9. CHECK_POINT_SEGMENTS=8  
  10. ENCODING=UNICODE  
  11. MIRROR_PORT_BASE=50000  
  12. REPLICATION_PORT_BASE=41000  
  13. MIRROR_REPLICATION_PORT_BASE=51000  
  14. declare -a MIRROR_DATA_DIRECTORY=(/home/wslu/gp/gpsql/data/mirror /home/wslu/gp/gpsql/data/mirror)  

注意:configs目录是我自己创建的、便于保存自定义配置文件的目录。该步骤的目的是创建一个初始化时要用的配置文件,并没有路径的要求。

 

(3)       在h93创建配置文件configs/hostfile_gpinitsystem,内容如下:

 

[python]   
 
  1. h93  
  2. h94  

注意:configs目录是我自己创建的、便于保存自定义配置文件的目录。该步骤的目的是创建一个初始化时要用的配置文件,并没有路径的要求。

 

(4)       在h93执行下述指令初始化集群:

 

[python]   
 
  1. [wslu@h93 gpsql]$ gpinitsystem -c configs/gpinitsystem_config -h configs/hostfile_gpinitsystem –a

(7)       此时,h94的data/master目录就不为空了:

 

[python]   
 
  1. $ [wslu@h94 gpsql]$ ls data/master/  
  2. gpseg-1  

 

 

10. 测试

[python]   
 
  1. [wslu@h93 gpsql]$ psql -p 5432 postgres  
  2. psql (8.3devel)  
  3. Type "help" for help.  
  4.    
  5. postgres=#  
  6. postgres=#  
  7. postgres=# \db  
  8.         List of tablespaces

  11.  pg_default | wslu  | pg_system  
  12.  pg_global  | wslu  | pg_system  
  13. (2 rows)  
至此,集群就初始化完成了。
集群初始化完成后,默认会启动集群。
 
 
---------------------------------------------------------华丽的分割线-------------------------------------------------------------
以下为Greenplum集群部分常用指令,以及关于配置单机多节点的一点说明。

11. 启动集群

以后,想手动启动集群,执行:

 

[python]   
 
  1. $ gpstart –a  

 

 

这里说一下,每次想使用集群的任何指令,必须执行:

 

[python]   
 
  1. $ source greenplum-path.sh  
  2. $ exportMASTER_DATA_DIRECTORY=/home/wslu/gp/gpsql/data/master/gpseg-1  

 

下文不再赘述。

 

12. 停止集群

 

[python]   
 
  1. $ gpstop –a  

 

 

13. 重启集群

 

[python]   
 
  1. $ gpstop –a –r  

 

 

14. 查看集群状态

 

[python]   
 
  1. $ gpstate –m | -e  

 

 

15. reload配置文件

在不停止集群情况下,若配置文件修改,reload配置文件:

 

[python]   
 
  1. $ gpstop –u  

 

 

16. 维护模式下启动master

仅仅启动master来执行维护管理任务,不会影响segment中的数据。例如,在维护模式下你可以仅连接master实例的数据库并且编辑系统表设置。

1.运行gpstart使用-m选项:

 

[python]   
 
  1. $ gpstart –m  

 

 

2.维护模式下连接master来维护系统表。例如:

 

[python]   
 
  1. $ PGOPTIONS='-c gp_session_role=utility'psql template1  

 

 

3.完成管理任务后,使master关闭工具模式。然后,重启进入正常模式:

 

[python]   
 
  1. $ gpstop -m  

 

 

17. 访问数据库

可以使用psql连接集群:

 

[python]   
 
  1.  [wslu@h93 gpsql]$ psql -p 5432 postgres  
  2. psql (8.3devel)  
  3. Type "help" for help.  
  4.    
  5. postgres=#  

 

基本上常见命令与PostgreSQL的相同。可参考PostgreSQL官方手册和Greenplum官方手册。

 

18. GUC参数配置

使用gpconfig设置guc参数

 

[python]   
 
  1. $ gpconfig -c gp_vmem_protect_limit -v4096MB  

 

gpconfig可以设置master和所有segment的guc参数,也可以使用--masteronly参数只设置master的参数。设置完guc参数后需要根据guc参数类型决定重启集群或reload配置文件。

显示guc参数

 

[python]   
 
  1. $ psql –c ‘showstatement_mem;’ 或 gpconfig –show statement_mem  
  2. $ psql –c ‘show all;’ 或 gpconfig –l  

 

 

19. 附录:关于配置单机多节点的说明

如果要配置单机多节点,比如只想在h93配置2个主segment、2个镜像segment、1个master,只需要把hostfile_config中的h94删掉,然后在h93删除data/primary,data/mirror,data/master目录下的内容,重新初始化即可。
