实现功能：自身集群扩容+租户资源扩容+租户资源扩容tpc-h测试

1.机器准备：

172.20.2.120:2881;172.20.2.121:2881;172.20.2.122:2881;172.20.2.120:3881;172.20.2.121:3881;172.20.2.122:3881

2.使用 OBD 自动化部署集群

  1. 安装 OBD 软件（在线）:
    yum install -y yum-utils
    yum-config-manager --add-repo https://mirrors.aliyun.com/oceanbase/OceanBase.repo
    yum install -y ob-deploy
  2. 编辑配置文件
     vim obce-3zones.yaml

  9. obd cluster deploy obce-3zones2 -c obce-3zones2.yaml

  10. 新文件copy进旧配置文件
    1.obd cluster list

    2.追加

  11. 重启集群
    obd cluster start obce-3zones

  12. 添加新进程（登录）
    alter system add server '172.20.2.120:3882' zone 'zone1';
    alter system add server '172.20.2.121:3882' zone 'zone2';
    alter system add server '172.20.2.122:3882' zone 'zone3';
  13. 查看成功结果
    select svr_ip,id,zone,status from __all_server;

3.新建租户
1.连接数据库
2.创建资源单元
CREATE RESOURCE UNIT S1 max_cpu=2, min_cpu=2, max_memory='2G', min_memory='2G',max_iops=1000, min_iops=1000, max_session_num=10000, max_disk_size='20G';
3.创建租户
create tenant test_tenant resource_pool_list=('pool1'); MySQL [(none)]> ALTER TENANT test_tenant SET VARIABLES ob_tcp_invited_nodes='%';
4.设置租户unit_num=1
alter resource pool pool1 unit_num=1;

4.tpc-h 测试
1.软件安装
TPC-H Tools Downloadhttp://tpc.org/TPC_Documents_Current_Versions/download_programs/tools-download-request5.asp?bm_type=TPC-H&bm_vers=3.0.0&mode=CURRENT-ONLYcd /root/TPC-H_Tools_v3.0.0/dbgen
cp makefile.suite Makefile

2.修改 Makefile 文件中的 CC、DATABASE、MACHINE 和 WORKLOAD 等参数定义。
vim Makefile +103
CC      = gcc
# Current values for DATABASE are: INFORMIX, DB2, TDAT (Teradata)
#                                  SQLSERVER, SYBASE, ORACLE, VECTORWISE
# Current values for MACHINE are:  ATT, DOS, HP, IBM, ICL, MVS,
#                                  SGI, SUN, U2200, VMS, LINUX, WIN32
# Current values for WORKLOAD are:  TPCH
DATABASE= MYSQL
MACHINE = LINUX
WORKLOAD = TPCH
3.修改 tpcd.h 文件，并添加新的宏定义。

vim tpcd.h +$
#ifdef MYSQL
#define GEN_QUERY_PLAN ""
#define START_TRAN "START TRANSACTION"
#define END_TRAN "COMMIT"
#define SET_OUTPUT ""
#define SET_ROWCOUNT "limit %d;\n"
#define SET_DBASE "use %s;\n"
#endif

4.编译：make
5.数据文件准备
   ./dbgen -s 100  --此处100参数可变，指定文件大小，单位g
6.将准备好的文件移至指定目录
   mkdir tpch10 mv *.tbl tpch100/
 7.查询语句准备
     mkdir tpch10 cp qgen queries/ cp dists.dss queries/ cd queries/ for i in `seq 22`; do echo $i;               ./qgen -d $i -s 10 > db"$i".sql; done dos2unix *.sql
 8.sql准备
    样例
          

9.租户参数设置
         set global autocommit=ON;
         set global ob_query_timeout=36000000000;
         set global ob_trx_timeout=36000000000;
         set global max_allowed_packet=67108864;
         set global ob_sql_work_area_percentage=80;
         /* 
         parallel_max_servers 和 parallel_servers_target 的值
         推荐设置为测试租户分配的 resource unit cpu 数的 10 倍
         如测试租户使用的 unit 配置为：create resource unit $unit_name max_cpu 26
         那么该值设置为 260*/
         set global parallel_max_servers=260;
         set global parallel_servers_target=260;

10.建表
              create tablegroup tpch_tg_100g_lineitem_order_group binding true partition by key 1            partitions 9;
      create tablegroup tpch_tg_100g_partsupp_part binding true partition by key 1 partitions 9;

        PRIMARY KEY (r_regionkey));
 11. 加载数据
      
 export MYSQL_PWD=123456
 python load.py

12.执行合并(使用 sys 租户登录)
    alter system major freeze;
    检查合并是否完成
    select name,value from oceanbase.__all_zone where name='frozen_version' or name='last_merged_version';--备注：frozen_version 和 last_merged_version 的值相等即表示合并完成。

13.测试sh
          vi tpch.sh    
    #!/bin/bash
    TPCH_TEST="obclient -h $host_ip -P $host_port -utpch_100g_part@tpch_mysql  -D tpch_100g_part  -ptest -c"
    #warmup预热
    for i in {1..22}
    do
       sql1="source db${i}.sql"
       echo $sql1| $TPCH_TEST >db${i}.log  || ret=1
    done
    #正式执行
    for i in {1..22}
    do
       starttime=`date +%s%N`
       echo `date  '+[%Y-%m-%d %H:%M:%S]'` "BEGIN Q${i}"
       sql1="source db${i}.sql"
       echo $sql1| $TPCH_TEST >db${i}.log  || ret=1
       stoptime=`date +%s%N`
       costtime=`echo $stoptime $starttime | awk '{printf "%0.2f\n", ($1 - $2) / 1000000000}'`
       echo `date  '+[%Y-%m-%d %H:%M:%S]'` "END,COST ${costtime}s"
    done
14.在扩容前导入数据执行sh tpch.sh得出单节点tpc-h 100g性能数据

15.扩容后修改租户unit_num数据量为3
     alter resource pool pool1 unit_num=3;

16.再次运行sh tpch.sh得出3节点下tpc-h性能数据

结果
