前一篇文章介绍了OBD白屏可视化方式部署OceanBase集群 ，其原理是把可视化设置生成为一个配置文件，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两个组件
服务器参数配置和 oceanbase-all-in-one-*.tar.gz 软件包下载，请参考上一篇文章
三台服务器 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.安装 all-in-one包
在192.168.113.161下安装all-in-one包，且会自动安装好ODB软件
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解压后，在 oceanbase-all-in-one/obd/usr/obd/example/ 目录下，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 ，复制到root目录：cp distributed-with-obproxy-example.yaml /root/zycluster-deploy.yaml
# 解压在 /mnt/software/oceanbase-all-in-one 目录
[root@db1 ~]# cd /mnt/software/oceanbase-all-in-one/obd/usr/obd/example/
[root@db1 example]# ll

根据我服务器配置调整 zycluster-deploy.yaml ，内容如下：

2.部署集群
部署： obd cluster deploy zycluster -c zycluster-deploy.yaml
销毁： obd cluster destory zycluster ，然后删除目录 rm -rf xxxx
部署成功后，在/root 目录下生成了一个 zycluster 目录，数据和日志默认存储 home_path (也就是 zycluster/store 目录下)，在真实场景下，请把data_dir 和 redo_dir 分别配置在独立的磁盘上，以提高IO性能和可用性
3.启动集群
启动：obd cluster start zycluster
4.使用Navicat连接集群sys系统租户
use oceanbase
查看资源，创建租户mq_t1
1.1.查看所有资源规格信息
SELECT * FROM DBA_OB_UNIT_CONFIGS;
1.2.删除资源规格
drop resource unit S1_unit_config;
1.3.创建资源规格（请按服务器真实配置和业务需求来设置合适资源大小）
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.查看所有资源池信息
SELECT * FROM DBA_OB_RESOURCE_POOLS;
2.2.创建资源池
CREATE RESOURCE POOL mq_pool_01 UNIT='S1_unit_config', UNIT_NUM=1, ZONE_LIST=('zone1','zone2','zone3');
3.1.查看所有的租户信息，其LOCALITY字段为租户副本分布
SELECT * FROM DBA_OB_TENANTS;
3.2.创建租户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.创建租户mq_t1, primary_zone=zone1;zone2;zone3，3个主zone同时读写提升数据库性能
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.删除租户
drop tenant mq_t1;
3.5查询租户
SELECT * FROM DBA_OB_TENANTS WHERE TENANT_NAME = 'mq_t1';
4.关联查询租户资源配置信息
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.查看租户的资源单元部署位置
SELECT a.TENANT_NAME,a.TENANT_ID,b.SVR_IP FROM DBA_OB_TENANTS a,GV$OB_UNITS b WHERE a.TENANT_ID=b.TENANT_ID;
6.查看节点的 Unit 信息
SELECT * FROM GV$OB_UNITS;
SELECT * FROM GV$OB_UNITS where TENANT_ID=1002;
7.查看 OBServer 的信息
SELECT * FROM GV$OB_SERVERS;
-- 停止服务节点
-- alter system start server '192.168.113.162:2882';
-- ALTER SYSTEM MINOR FREEZE SERVER = ('192.168.113.162:2882');
下图可看到mq_t1租户创建成功，该租户初始密码为空，使用：obclient -h192.168.113.161 -P2883 -uroot -p’/aVi*H8(0%FS_YwZ-|dmo&[hjlT7pe@E’ -Doceanbase -A 进入mq_t1租户
还可通过Navicat进入 mq_t1租户，初始密码为空，进入oceanbase后修改租户密码
5.创建数据库和添加数据
在 mq_t1 租户下创建zypcy数据库，创建person表，添加2条数据
