前一篇文章介紹了OBD白屏可視化方式部署OceanBase集群 ，其原理是把可視化設(shè)置生成為一個配置文件，然后使用OBD命令部署集群

本篇想使用命令行加配置文件方式，只部署OceanBase和ODProxy兩個組件

服務(wù)器參數(shù)配置和 oceanbase-all-in-one-*.tar.gz 軟件包下載，請參考上一篇文章

三臺服務(wù)器 192.168.113.161 、162、163 ，都需要在 /etc/sysctl.conf 中加入配置：

vm.max_map_count=655360
fs.file-max=6573688

使配置生效：sysctl -p

1.安裝 all-in-one包

在192.168.113.161下安裝all-in-one包，且會自動安裝好ODB軟件

tar -xzf oceanbase-all-in-one-*.tar.gz
cd oceanbase-all-in-one/bin/
./install.sh
source ~/.oceanbase-all-in-one/bin/env.sh

tar解壓后，在 oceanbase-all-in-one/obd/usr/obd/example/ 目錄下，有示例配置文件，因我只要部署OceanBase和OBProxy，就使用了 distributed-with-obproxy-example.yaml ，復(fù)制到root目錄：cp distributed-with-obproxy-example.yaml /root/zycluster-deploy.yaml

# 解壓在 /mnt/software/oceanbase-all-in-one 目錄
[root@db1 ~]# cd /mnt/software/oceanbase-all-in-one/obd/usr/obd/example/
[root@db1 example]# ll

根據(jù)我服務(wù)器配置調(diào)整 zycluster-deploy.yaml ，內(nèi)容如下：

2.部署集群

部署： obd cluster deploy zycluster -c zycluster-deploy.yaml
銷毀： obd cluster destory zycluster ，然后刪除目錄 rm -rf xxxx

部署成功后，在/root 目錄下生成了一個 zycluster 目錄，數(shù)據(jù)和日志默認(rèn)存儲 home_path (也就是 zycluster/store 目錄下)，在真實場景下，請把data_dir 和 redo_dir 分別配置在獨立的磁盤上，以提高IO性能和可用性

3.啟動集群

啟動：obd cluster start zycluster

4.使用Navicat連接集群sys系統(tǒng)租戶

use oceanbase
查看資源，創(chuàng)建租戶mq_t1

1.1.查看所有資源規(guī)格信息
SELECT * FROM DBA_OB_UNIT_CONFIGS;
1.2.刪除資源規(guī)格
drop resource unit S1_unit_config;
1.3.創(chuàng)建資源規(guī)格（請按服務(wù)器真實配置和業(yè)務(wù)需求來設(shè)置合適資源大小）
CREATE RESOURCE UNIT S1_unit_config MEMORY_SIZE = '4G', MAX_CPU = 1, MIN_CPU = 1, LOG_DISK_SIZE = '2G',  MAX_IOPS = 10000, MIN_IOPS = 10000, IOPS_WEIGHT=1;2.1.查看所有資源池信息
SELECT * FROM DBA_OB_RESOURCE_POOLS;
2.2.創(chuàng)建資源池
CREATE RESOURCE POOL mq_pool_01  UNIT='S1_unit_config', UNIT_NUM=1, ZONE_LIST=('zone1','zone2','zone3');3.1.查看所有的租戶信息，其LOCALITY字段為租戶副本分布
SELECT * FROM DBA_OB_TENANTS;
3.2.創(chuàng)建租戶mq_t1，primary_zone=zone1
CREATE TENANT IF NOT EXISTS mq_t1  PRIMARY_ZONE='zone1', RESOURCE_POOL_LIST=('mq_pool_01') set OB_TCP_INVITED_NODES='%';
3.3.創(chuàng)建租戶mq_t1, primary_zone=zone1;zone2;zone3，3個主zone同時讀寫提升數(shù)據(jù)庫性能
CREATE TENANT IF NOT EXISTS mq_t1  PRIMARY_ZONE='zone1;zone2;zone3', RESOURCE_POOL_LIST=('mq_pool_01') set OB_TCP_INVITED_NODES='%';
3.4.刪除租戶
drop tenant mq_t1;
3.5查詢租戶
SELECT * FROM DBA_OB_TENANTS WHERE TENANT_NAME = 'mq_t1';4.關(guān)聯(lián)查詢租戶資源配置信息
SELECT c.TENANT_ID, e.TENANT_NAME, concat(c.NAME, ': ', d.NAME) `pool:conf`,concat(c.UNIT_COUNT, ' unit: ', d.min_cpu, 'C/', ROUND(d.MEMORY_SIZE/1024/1024/1024,0), "G") unit_info FROM DBA_OB_RESOURCE_POOLS c, DBA_OB_UNIT_CONFIGS d, DBA_OB_TENANTS e  WHERE c.UNIT_CONFIG_ID=d.UNIT_CONFIG_ID AND c.TENANT_ID=e.TENANT_ID AND c.TENANT_ID>1000 ORDER BY c.TENANT_ID;5.查看租戶的資源單元部署位置
SELECT a.TENANT_NAME,a.TENANT_ID,b.SVR_IP FROM DBA_OB_TENANTS a,GV$OB_UNITS b WHERE a.TENANT_ID=b.TENANT_ID;6.查看節(jié)點的 Unit 信息
SELECT * FROM GV$OB_UNITS;
SELECT * FROM GV$OB_UNITS where TENANT_ID=1002;7.查看 OBServer 的信息
SELECT * FROM GV$OB_SERVERS;-- 停止服務(wù)節(jié)點
-- alter system start server '192.168.113.162:2882';
-- ALTER SYSTEM  MINOR FREEZE SERVER = ('192.168.113.162:2882');

下圖可看到mq_t1租戶創(chuàng)建成功，該租戶初始密碼為空，使用：obclient -h192.168.113.161 -P2883 -uroot -p’/aVi*H8(0%FS_YwZ-|dmo&[hjlT7pe@E’ -Doceanbase -A 進(jìn)入mq_t1租戶

還可通過Navicat進(jìn)入 mq_t1租戶，初始密碼為空，進(jìn)入oceanbase后修改租戶密碼

5.創(chuàng)建數(shù)據(jù)庫和添加數(shù)據(jù)

在 mq_t1 租戶下創(chuàng)建zypcy數(shù)據(jù)庫，創(chuàng)建person表，添加2條數(shù)據(jù)
