原创 国内数据库 作者:digoal 时间:2018-10-09 13:44:40 0 删除 编辑

背景

多机部署deepgreen,与greenplum部署方法类似。

本文仅用于测试。

1 环境

与之前测试citus的环境一致,9台ECS虚拟机。

xxx.xxx.xxx.228 digoal-citus-gpdb-test001  
xxx.xxx.xxx.224 digoal-citus-gpdb-test002  
xxx.xxx.xxx.230 digoal-citus-gpdb-test003  
xxx.xxx.xxx.231 digoal-citus-gpdb-test004  
xxx.xxx.xxx.225 digoal-citus-gpdb-test005  
xxx.xxx.xxx.227 digoal-citus-gpdb-test006  
xxx.xxx.xxx.232 digoal-citus-gpdb-test007  
xxx.xxx.xxx.226 digoal-citus-gpdb-test008  
xxx.xxx.xxx.229 digoal-citus-gpdb-test009

1、配置时,请使用实际主机名

# hostname -s  
  
例如返回:  
digoal-citus-gpdb-test005

2、ECS的配置

CentOS 7 x64  
  
32 core  
  
128G  
  
2TB

2 配置OS (所有ECS)

1、新建OS普通用户,用于启动deepgreen

# useradd postgres  
  
# passwd postgres  
  
pwd .......

2、目录规划,目录权限

# mkdir /data01/dp  
# chown postgres:postgres /data01/dp

3、配置SSHd,允许KEY认证

# echo "PubkeyAuthentication yes" >> /etc/ssh/sshd_config   
  
# systemctl restart sshd.service

4、配置名字解析

# echo "xxx.xxx.xxx.228 digoal-citus-gpdb-test001" >>/etc/hosts  
# echo "xxx.xxx.xxx.224 digoal-citus-gpdb-test002" >>/etc/hosts  
# echo "xxx.xxx.xxx.230 digoal-citus-gpdb-test003" >>/etc/hosts  
# echo "xxx.xxx.xxx.231 digoal-citus-gpdb-test004" >>/etc/hosts  
# echo "xxx.xxx.xxx.225 digoal-citus-gpdb-test005" >>/etc/hosts  
# echo "xxx.xxx.xxx.227 digoal-citus-gpdb-test006" >>/etc/hosts  
# echo "xxx.xxx.xxx.232 digoal-citus-gpdb-test007" >>/etc/hosts  
# echo "xxx.xxx.xxx.226 digoal-citus-gpdb-test008" >>/etc/hosts  
# echo "xxx.xxx.xxx.229 digoal-citus-gpdb-test009" >>/etc/hosts

3 安装deepgreen软件 (master ECS)

1、下载软件

# su - postgres  
  
$ wget https://s3.amazonaws.com/vitessedata/download/deepgreendb.18.08.rh7.x86_64.180825.bin

2、修改权限

$ chmod 700 deepgreendb.18.08.rh7.x86_64.180825.bin

3、安装软件

$ ./deepgreendb.18.08.rh7.x86_64.180825.bin

4、配置环境变量

$ vi ./deepgreendb/greenplum_path.sh  
  
#追加  
# 使用实际目录  
export MASTER_DATA_DIRECTORY=/data01/dp/dg-1  
export PGDATA=$MASTER_DATA_DIRECTORY  
export PGHOST=127.0.0.1  
export PGPORT=15432  
# 使用os用户名  
export PGUSER=postgres  
export PGPASSWORD=123  
export PGDATABASE=postgres

5、使用环境变量

$ . ./deepgreendb/greenplum_path.sh

6、编写HOST文件 (9台ECS的HOSTNAME写入) (用于配置、初始化deepgreen集群)

$ vi hostfile  
  
digoal-citus-gpdb-test001  
digoal-citus-gpdb-test002  
digoal-citus-gpdb-test003  
digoal-citus-gpdb-test004  
digoal-citus-gpdb-test005  
digoal-citus-gpdb-test006  
digoal-citus-gpdb-test007  
digoal-citus-gpdb-test008  
digoal-citus-gpdb-test009

7、交换SSH KEY,配置KEY互信

$ gpssh-exkeys -f ./hostfile  
  
输入一次 pwd.......

4 拷贝软件到其他ECS (master ECS)

1、打包

$ tar -zcvf deepgreendb.18.08.180825.tar.gz deepgreendb.18.08.180825

2、拷贝到其他ECS

$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test002:~/  
$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test003:~/  
$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test004:~/  
$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test005:~/  
$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test006:~/  
$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test007:~/  
$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test008:~/  
$ scp deepgreendb.18.08.180825.tar.gz digoal-citus-gpdb-test009:~/

3、解压软件

$ gpssh -h digoal-citus-gpdb-test002 -h digoal-citus-gpdb-test003 -h digoal-citus-gpdb-test004 -h digoal-citus-gpdb-test005 -h digoal-citus-gpdb-test006 -h digoal-citus-gpdb-test007 -h digoal-citus-gpdb-test008 -h digoal-citus-gpdb-test009  
  
=> tar -zxvf deepgreendb.18.08.180825.tar.gz >/dev/null  
=> ln -s `pwd`/deepgreendb.18.08.180825 `pwd`/deepgreendb

5 初始化deepgreen 数据库集群 (master ECS)

每个ECS上跑16个segment。数据目录 /data01/dp

hostfile里面包含9台ECS hostname,如果master不想跑segment,则把它从hostfile删掉即可。

digoal-citus-gpdb-test001 作为 master节点

1、按以上要求编写配置文件

$ vi cluster.conf   
  
ARRAY_NAME="mpp1 cluster"  
CLUSTER_NAME="mpp1 cluster"  
MACHINE_LIST_FILE=hostfile  
SEG_PREFIX=dg  
DATABASE_PREFIX=dg  
PORT_BASE=25432  
declare -a DATA_DIRECTORY=(/data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp /data01/dp)  
MASTER_HOSTNAME=digoal-citus-gpdb-test001  
MASTER_DIRECTORY=/data01/dp  
MASTER_PORT=15432  
IP_ALLOW=0.0.0.0/0  
TRUSTED_SHELL=/usr/bin/ssh  
CHECK_POINT_SEGMENTS=32  
ENCODING=UNICODE  
export MASTER_DATA_DIRECTORY  
export TRUSTED_SHELL  
DEFAULT_QD_MAX_CONNECT=25  
QE_CONNECT_FACTOR=5

2、初始化数据库集群

gpinitsystem -c cluster.conf -h hostfile

生成集群,一共144 segments

3、参数

postgres=# select source,category,name,setting,unit from pg_settings where source<>'default' or name ~ '^gp_' or name ~ '^vitesse' order by source,category,name;

6 sf=200 tpc-h 测试

1、使用gp_tpch测试,200G数据集。TPC-H

# su - postgres  
  
$ git clone https://github.com/digoal/gp_tpch  
$ cd gp_tpch  
$ make  
  
  
$ ln -s `pwd` /tmp/dss-data  
  
$ ./dbgen -s 200  
  
$ for i in `ls *.tbl`; do sed 's/|$//' $i > ${i/tbl/csv}; echo $i; done;  
  
$ SF=200  
$ mkdir dss/queries  
$ for q in `seq 1 22`  
do  
    DSS_QUERY=dss/templates ./qgen -s $SF $q > dss/queries/$q.sql  
    sed 's/^select/explain select/' dss/queries/$q.sql > dss/queries/$q.explain.sql  
done  
  
模板  
$ ./tpch.sh ./results_gpdb ip port tpch-db tpch-user password {row|column|redshift|pg|pg10|citus}  
  
  
$ ./tpch.sh ./results_gpdb 127.0.0.1 15432 postgres postgres pwd column

2、测试结果(比citus好很多)

UPDATE,DELETE都是表级锁,使用2PC,OLTP性能无法直视。(Citus这方面就做德很好。)

greenplum VS citus

《PostgreSQL sharding : citus 系列2 - TPC-H》

《PostgreSQL sharding : citus 系列1 - 多机部署(含OLTP(TPC-B)测试)》

小结

1、citus 适合oltp多一点,AP偏少的系统(如果有复杂的OLAP需求,必须write in sql , thinking in mapreduce, 或者使用greenplum生成的执行计划,把broadcase, remotion的动作割开,使用临时表代替来实现。)。

2、greenplum适合OLAP系统。(基本无法适合OLTP)。
