创建docker greenplum 容器以及greenplum 监控(GPCC)

下载基础镜像centos

docker pull centos:6.8

创建容器

docker run -tid --name gp -p 5432:5432 -p 28080:28080 -v I:\gp\gp:/gp centos:6.8 /bin/bash (gp文件夹里包括GP安装包和GPCC安装包)

进入容器

docker exec -ti gp /bin/bash

安装ssh服务

yum install openssh-server -y

yum install openssh-clients -y

安装unzip

yum install unzip -y

安装依赖

yum install ed -y

修改时区

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

解压并安装greenplum和gpcc

运行两个bin文件安装

创建gpadmin用户

useradd gpadmin

passwd gpadmin

mkdir gpmaster

mkdir gpsegments

修改gp所有者

chown -R gpadmin /gpmaster

chown -R gpadmin /gpsegments

chown -R gpadmin /usr/local/greenplum-db

chgrp  -R gpadmin /usr/local/greenplum-db

chown -R gpadmin /usr/local/greenplum-db-4.3.9.1

chgrp -R gpadmin /usr/local/greenplum-db-4.3.9.1

chown -R gpadmin:gpadmin /usr/local/greenplum-cc-web

chown -R gpadmin:gpadmin /usr/local/greenplum-cc-web-2.0.0-build-32

修改环境变量

vi /etc/profile

    GPHOME=/usr/local/greenplum-db-4.3.9.1

    PATH=$GPHOME/bin:$GPHOME/ext/Python/bin:$PATH

    export GPHOME

export PATH

vi ~/.bashrc添加:

 

source /etc/profile

service sshd start

su – gpadmin

 

source ~/.bashrc

进入gpadmin用户添加

vi ~/.bashrc

添加 :

 

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

source /usr/local/greenplum-cc-web/gpcc_path.sh

MASTER_DATA_DIRECTORY=/gpmaster/gpseg-1

export MASTER_DATA_DIRECTORY

export PGPORT=5432

export PGDATABASE=postgres

 

source ~/.bashrc

 

创建修改启动配置文件

mkdir gpconfigs

vi all_segs(填从节点的ip或者主机名,单节点就填localhost就可以)

vi all_hosts(填所有节点的ip或者主机名,单节点可以不需要)

cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config /home/gpadmin/gpconfigs/gpinitsystem_config

vi /home/gpadmin/gpconfigs/gpinitsystem_config

修改这个文件

ENCODING=UTF8

declare -a DATA_DIRECTORY=(/gpsegments /gpsegments)(需要几个从节点就几个文件夹)

MASTER_DIRECTORY=/gpmaster(主节点存储位置)

MASTER_HOSTNAME=localhost(放在同一个容器里就设为localhost,集群几个容器的话,就填master节点名)

建立ssh免密登录

gpssh-exkeys -f ./all_segs

初始化GP

gpinitsystem -c gpconfigs/gpinitsystem_config -h ./all_segs -a

初始化完成后

psql -p 1949 -d postgres

可以进入GP

 

远程访问的话需要

echo "host all all 172.17.0.1/24 md5">>/gpmaster/gpseg-1/pg_hba.conf(172.17.0.1是容器的网关地址)

在gp中

postgres=# ALTER role gpadmin with password 'gpadmin';

然后重启gp

gpstop -u

 

 

安装gpcc监控

echo "host gpperfmon gpmon ::1/128 md5">>/gpmaster/gpseg-1/pg_hba.conf

echo "gp_enable_gpperfmon=on">>/gpmaster/gpseg-1/postgresql.conf

echo "gpperfmon_port=8888">>/gpmaster/gpseg-1/postgresql.conf

echo "gp_external_enable_exec=on">>/gpmaster/gpseg-1/postgresql.conf

echo "gpperfmon_log_alert_level=warning">>/gpmaster/gpseg-1/postgresql.conf

安装gp监控数据库

gpperfmon_install --enable --password gpmon --port 5432

在gp中

postgres=# ALTER role gpadmin with password 'gpadmin';

然后重启gp

gpstop -ar

安装监控实例

gpcmdr --setup

gpcmdr --start gpcc(gpcc是上一步命的名)

 

GPCCC启动了输入网址10.0.75.1:28080   默认用户名密码为gpmon
