    原文链接:https://blog.51cto.com/jxzhfei/1766666

    环境:

    服务器版本:centos 6.5

    数据库版本:greenplum-db-4.2.8.5-build-1-RHEL5-x86_64.zip

    1.创建用户和组gpadmin

    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:

    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

    以上参数可以根据自己系统配置做适当修改

    手工执行命令,让参数生效

    [root@gpmaster ~]# sysctl -p

    在limits.conf文件中添加如下配置

    [root@gpmaster ~]# vi /etc/security/limits.conf

    # End of file

    * soft nofile 65536

    * hard nofile 65536

    * soft nproc 131072

    * hard nproc 131072

    配置用户ssh用户无密码登录,单机也得配置

    [root@gpmaster ~]# su - gpadmin

    [gpadmin@gpmaster ~]$ mkdir ~/.ssh

    [gpadmin@gpmaster ~]$ chmod 700 ~/.ssh

    [gpadmin@gpmaster ~]$ cd .ssh/

    [gpadmin@gpmaster .ssh]$ ssh-keygen -t rsa

    [gpadmin@gpmaster .ssh]$ ssh gpmaster cat /home/gpadmin/.ssh/id_rsa.pub >>authorized_keys

    [gpadmin@gpmaster .ssh]$chmod 600 authorized_keys

    [gpadmin@gpmaster .ssh]$ ssh gpmaster date

    2.安装GP软件

    方式一:

    [root@gpmaster ~]# unzip greenplum-db-4.2.8.5-build-1-RHEL5-x86_64.zip

    [root@gpmaster ~]# ./greenplum-db-4.2.8.5-build-1-RHEL5-x86_64.bin

    方式二:

    [root@gpmaster ~]# rpm -ivh greenplum-db-4.2....

    创建instance需要的目录

    [root@gpmaster ~]# mkdir -p /app/master

    [root@gpmaster ~]# mkdir -p /app/data/gp1

    [root@gpmaster ~]# mkdir -p /app/data/gp2

    [root@gpmaster ~]# mkdir -p /app/data/gp3

    [root@gpmaster ~]# mkdir -p /app/data/gp4

    修改目录属主:

    [root@gpmaster ~]# chown -R gpadmin:gpadmin /usr/local/greenplum-db*

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

    [root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp1

    [root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp2

    [root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp3

    [root@gpmaster ~]# chown -R gpadmin:gpadmin /app/data/gp4

    修改gpadmin用户环境配置:

    [root@gpmaster ~]# su - gpadmin

    [gpadmin@gpmaster ~]$ vi .bash_profile

    source /usr/local/greenplum-db/greenplum_path.sh

    export MASTER_DATA_DIRECTORY=/app/master/gpseg-1

    export PGPORT=5432

    export PGUSER=gpadmin

    export PGDATABASE=gpmaster

    生效:

    [gpadmin@gpmaster ~]$ source .bash_profile

    编辑all_hosts_file文件,添加如下内容:

    [gpadmin@gpmaster ~]$ vi all_hosts_file

    gpmaster

    执行如下命令验证用户等效性

    [gpadmin@gpmaster ~]$ gpssh-exkeys -f all_hosts_file

    3.初始化系统:

    编辑系统初始化的参数文件,这个文件的编辑可以使用模版,模板文件所在目录如下:

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

    编辑gp参数文件,修改如下配置:

    [gpadmin@gpmaster ~]$ vi gpinitsystem_config

    declare -a DATA_DIRECTORY=(/app/data/gp1 /app/data/gp2 /app/data/gp3 /app/data/gp4)

    MASTER_HOSTNAME=gpmaster

    MASTER_DIRECTORY=/app/master

    DATABASE_NAME=gpmaster

    编辑seg_hosts_file文件

    [gpadmin@gpmaster ~]$ vi seg_hosts_file

    gpmaster

    执行初始化系统命令:

    [gpadmin@gpmaster ~]$ gpinitsystem -c gpinitsystem_config -h seg_hosts_file

    系统开始初始化,之后会看到如下提示:

    Continue with Greenplum creation Yy/Nn>

    输入 Y ,按回车,系统会初始化完成

    安装结束可以连接GP数据库了:

    [gpadmin@gpmaster ~]$ psql -d gpmaster

    psql (8.2.15)

    Type "help" for help.

    gpmaster=#

    创建数据库

    [gpadmin@gpmaster ~]$ createdb testDB -E utf-8

    给数据库权限

    [gpadmin@gpmaster ~]$ psql -d gpmaster

    psql (8.2.15)

    Type "help" for help.

    gpmaster=# c testDB

    You are now connected to database "testDB" as user "gpadmin".

    testDB=# alter role gpadmin with password 'gpadmin';

    远程权限

    [gpadmin@gpmaster ~]$ cd $MASTER_DATA_DIRECTORY/

    [gpadmin@gpmaster gpseg-1]$ ls

    base               pg_distributedlog     pg_stat_tmp            pg_xlog

    global             pg_distributedxidmap  pg_subtrans            postgresql.conf

    gp_dbid            pg_hba.conf           pg_tblspc              postmaster.opts

    gpperfmon          pg_ident.conf         pg_twophase            postmaster.pid

    pg_changetracking  pg_log                pg_utilitymodedtmredo

    pg_clog            pg_multixact          PG_VERSION

    [gpadmin@gpmaster gpseg-1]$

    [gpadmin@gpmaster gpseg-1]$ vi pg_hba.conf

    host     testDB      gpadmin         192.168.96.1/32    md5

    通过gpstop -u命令使配置生效

    [gpadmin@gpmaster gpseg-1]$ gpstop -u

    通过其他机器登录数据库

    $ psql -h192.168.96.128 -p5432 -d testDB -Ugpadmin
