1、主机规划
| 主机名 | ip | 内存(G) | cpu | 安装软件 | 占用端口 |
| mgr1 | 172.16.80.57 | 128 | 32 | observer（zone1）、obclient | 3881、3882、 4881、4882 |
| mgr2 | 172.16.80.58 | 128 | 32 | observer（zone2）、obclient、obproxy | 3881、3882、 4881、4882、3883 |
| mgr3 | 172.16.80.59 | 128 | 32 | observer（zone3）、obclient | 3881、3882、 4881、4882 |
2、所有主机初始化
按照文档
执行：
【2、所有主机初始化（关键步骤）】对主机初始化
【3、安装ob集群--安装oceanbase软件、安装obclient】
3、清理目录（第一次部署不用）
三个主机都要执行：
kill掉observer进程
ps -ef|grep observer
kill -9 17397 19716
/bin/rm -rf ~/{node1,node2} /data/{1,log1}/{node1,node2}
4、创建目录
三个主机都要执行：
su - admin
for i in {node1,node2}; do \
echo $i; \
mkdir -p ~/$i/{admin,bin,etc}; cp ~/oceanbase/bin/* ~/$i/bin/;cd ~; \
cp ~/oceanbase/admin/* ~/$i/admin/;cd ~; \
cp -r ~/oceanbase/etc/* ~/$i/etc/;cd ~; \
rm -f ~/$i/etc/observer.config.bin;rm -f ~/$i/etc/observer.config.bin.history;cd ~; \
mkdir -p /data/1/$i/obcc/{etc3,sort_dir,sstable} /data/log1/$i/obcc/{clog,etc2,ilog,slog,oob_clog} ;\
mkdir -p ~/$i/store/obcc; \
for t in {etc3,sort_dir,sstable};do ln -s /data/1/$i/obcc/$t /home/admin/$i/store/obcc/$t; done; \
for t in {clog,etc2,ilog,slog,oob_clog};do ln -s /data/log1/$i/obcc/$t /home/admin/$i/store/obcc/$t; done; \
done
tree ~/node*
tree /data/{1,log1}/node*
5、初始化OB集群

mgr3（zone3）:
su - admin

6、bootstrap集群（集群搭建是否成功的关键步骤）
选择一个机器，直接不输入密码
mysql -h127.1 -uroot -P3881 -p
Enter password:
set session ob_query_timeout=1000000000;
alter system bootstrap ZONE 'zone1' SERVER '172.16.80.57:3882', ZONE 'zone2' SERVER '172.16.80.58:3882', ZONE 'zone3' SERVER '172.16.80.59:3882' ;
alter user root identified by '******';
注意：
如果这一步失败报错了，其原因很可能就是三节点或单节点的 observer 进程启动参数有不对、observer 相关目录权限不对、日志目录空间不足一定比例(跟数据目录合用了大目录，空间被数据目录占用了)、三节点时间不同步、节点内存资源不足等等。请先排查这些问题点后，然后从【清理ob目录】开始重新初始化
7、验证集群初始化成功
mysql -h127.1 -uroot@sys -P3881 -p -c -A
show databases; --显示oceanbase即可
MySQL [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| oceanbase |
| information_schema |
| mysql |
| SYS |
| LBACSYS |
| ORAAUDITOR |
| test |
+--------------------+
7 rows in set (0.00 sec)
8、扩容
alter system add server '172.16.80.57:4882' zone 'zone1';
alter system add server '172.16.80.58:4882' zone 'zone2';
alter system add server '172.16.80.59:4882' zone 'zone3' ;
9、验证主机资源
MySQL [(none)]> use oceanbase;
Database changed
select * from __all_server;
select a.zone,concat(a.svr_ip,':',a.svr_port) observer, cpu_total, (cpu_total-cpu_assigned) cpu_free,disk_total,(disk_total-disk_assigned) disk_free, round(mem_total/1024/1024/1024) mem_total_gb, round((mem_total-mem_assigned)/1024/1024/1024) mem_free_gb, usec_to_time(b.last_offline_time) last_offline_time, usec_to_time(b.start_service_time) start_service_time
from __all_virtual_server_stat a join __all_server b on (a.svr_ip=b.svr_ip and a.svr_port=b.svr_port) order by a.zone, a.svr_ip;
select t1.name resource_pool_name, t2.`name` unit_config_name, t2.max_cpu, t2.min_cpu, round(t2.max_memory/1024/1024/1024) max_mem_gb, round(t2.min_memory/1024/1024/1024) min_mem_gb, t2.max_disk_size/1024/1024/1024 ,t2.max_session_num,t3.unit_id, t3.zone, concat(t3.svr_ip,':',t3.`svr_port`) observer,t4.tenant_id, t4.tenant_name
from __all_resource_pool t1 join __all_unit_config t2 on (t1.unit_config_id=t2.unit_config_id) join __all_unit t3 on (t1.`resource_pool_id` = t3.`resource_pool_id`)
left join __all_tenant t4 on (t1.tenant_id=t4.tenant_id)
order by t1.`resource_pool_id`, t2.`unit_config_id`, t3.unit_id;
10、创建租户
CREATE resource unit oracle_unit_config max_cpu=8, min_cpu=4, max_memory='1G', min_memory='1G', max_iops=10000, min_iops=1000, max_session_num=1000000, max_disk_size='100G';
select * from __all_unit_config;
CREATE resource pool oracle_pool unit = 'oracle_unit_config', unit_num = 1;
select * from __all_resource_pool;
CREATE tenant oracle_cc resource_pool_list=('oracle_pool'), primary_zone='RANDOM',comment 'oracle tenant/instance', charset='utf8mb4' set ob_tcp_invited_nodes='%', ob_compatibility_mode='oracle';
select * from __all_tenant;
11、查询剩余资源
select a.zone,concat(a.svr_ip,':',a.svr_port) observer, cpu_total, (cpu_total-cpu_assigned) cpu_free,disk_total,(disk_total-disk_assigned) disk_free, round(mem_total/1024/1024/1024) mem_total_gb, round((mem_total-mem_assigned)/1024/1024/1024) mem_free_gb, usec_to_time(b.last_offline_time) last_offline_time, usec_to_time(b.start_service_time) start_service_time
from __all_virtual_server_stat a join __all_server b on (a.svr_ip=b.svr_ip and a.svr_port=b.svr_port) order by a.zone, a.svr_ip;
select t1.name resource_pool_name, t2.`name` unit_config_name, t2.max_cpu, t2.min_cpu, round(t2.max_memory/1024/1024/1024) max_mem_gb, round(t2.min_memory/1024/1024/1024) min_mem_gb, t2.max_disk_size/1024/1024/1024 ,t2.max_session_num,t3.unit_id, t3.zone, concat(t3.svr_ip,':',t3.`svr_port`) observer,t4.tenant_id, t4.tenant_name
from __all_resource_pool t1 join __all_unit_config t2 on (t1.unit_config_id=t2.unit_config_id) join __all_unit t3 on (t1.`resource_pool_id` = t3.`resource_pool_id`)
left join __all_tenant t4 on (t1.tenant_id=t4.tenant_id)
order by t1.`resource_pool_id`, t2.`unit_config_id`, t3.unit_id;
12、初始化oracle租户的sys密码
由于oracle_cc的unit_num为1，且根据资源占用oracle的租户占用的是4882端口，所以要访问4881端口
obclient -h172.16.80.57 -usys@oracle_cc -P4881 -p -c -A
alter user sys identified by 123456;
13、创建普通用户和分区表
create user cc identified by ******;
grant dba to cc;
create table test_acid_a (id int, col1 char(10)) partition by hash(id) partitions 9;
insert into test_acid_a values(1,0),(2,0),(3,0),(4,0),(5,0),(6,0),(7,0),(8,0),(9,0),(10,0),(11,0),(12,0);
commit;
14、查看当前partition分布
SELECT t.tenant_id, a.tenant_name, t.table_name, d.database_name, tg.tablegroup_name , t.part_num , t2.partition_id, t2.ZONE, concat(t2.svr_ip,':',t2.svr_port)
, a.primary_zone , IF(t.locality = '' OR t.locality IS NULL, a.locality, t.locality) AS locality
FROM oceanbase.__all_tenant AS a
JOIN oceanbase.__all_virtual_database AS d ON ( a.tenant_id = d.tenant_id )
JOIN oceanbase.__all_virtual_table AS t ON (t.tenant_id = d.tenant_id AND t.database_id = d.database_id)
JOIN oceanbase.__all_virtual_meta_table t2 ON (t.tenant_id = t2.tenant_id AND (t.table_id=t2.table_id OR t.tablegroup_id=t2.table_id) AND t2.ROLE IN (1) )
LEFT JOIN oceanbase.__all_virtual_tablegroup AS tg ON (t.tenant_id = tg.tenant_id and t.tablegroup_id = tg.tablegroup_id)
WHERE t.table_type IN (3)
ORDER BY t.tenant_id, tg.tablegroup_name, d.database_name, t.table_name, t2.partition_id
;
14、扩容oracle租户
（1）增大resource unit的内存
alter resource unit oracle_unit_config max_memory='2G';
alter resource unit oracle_unit_config min_memory='2G';
（2）增大unit的数量
alter resource pool oracle_pool unit_num=2;
OB 的租户扩容几乎是瞬间完成的。
当然生产环境有数据，扩容可能会引起数据负载均衡。
命令是立即返回，数据迁移是后台异步做的，根据数据量确定平滑迁移时间。这是 OB 独特之处
扩容后partition的分布（要等一段时间）
SELECT t.tenant_id, a.tenant_name, t.table_name, d.database_name, tg.tablegroup_name , t.part_num , t2.partition_id, t2.ZONE, concat(t2.svr_ip,':',t2.svr_port)
, a.primary_zone , IF(t.locality = '' OR t.locality IS NULL, a.locality, t.locality) AS locality
FROM oceanbase.__all_tenant AS a
JOIN oceanbase.__all_virtual_database AS d ON ( a.tenant_id = d.tenant_id )
JOIN oceanbase.__all_virtual_table AS t ON (t.tenant_id = d.tenant_id AND t.database_id = d.database_id)
JOIN oceanbase.__all_virtual_meta_table t2 ON (t.tenant_id = t2.tenant_id AND (t.table_id=t2.table_id OR t.tablegroup_id=t2.table_id) AND t2.ROLE IN (1) )
LEFT JOIN oceanbase.__all_virtual_tablegroup AS tg ON (t.tenant_id = tg.tenant_id and t.tablegroup_id = tg.tablegroup_id)
WHERE t.table_type IN (3)
ORDER BY t.tenant_id, tg.tablegroup_name, d.database_name, t.table_name, t2.partition_id
;
（3）检查资源占用
select a.zone,concat(a.svr_ip,':',a.svr_port) observer, cpu_total, (cpu_total-cpu_assigned) cpu_free,disk_total,(disk_total-disk_assigned) disk_free, round(mem_total/1024/1024/1024) mem_total_gb, round((mem_total-mem_assigned)/1024/1024/1024) mem_free_gb, usec_to_time(b.last_offline_time) last_offline_time, usec_to_time(b.start_service_time) start_service_time
from __all_virtual_server_stat a join __all_server b on (a.svr_ip=b.svr_ip and a.svr_port=b.svr_port) order by a.zone, a.svr_ip;
select t1.name resource_pool_name, t2.`name` unit_config_name, t2.max_cpu, t2.min_cpu, round(t2.max_memory/1024/1024/1024) max_mem_gb, round(t2.min_memory/1024/1024/1024) min_mem_gb, t2.max_disk_size/1024/1024/1024 ,t2.max_session_num,t3.unit_id, t3.zone, concat(t3.svr_ip,':',t3.`svr_port`) observer,t4.tenant_id, t4.tenant_name
from __all_resource_pool t1 join __all_unit_config t2 on (t1.unit_config_id=t2.unit_config_id) join __all_unit t3 on (t1.`resource_pool_id` = t3.`resource_pool_id`)
left join __all_tenant t4 on (t1.tenant_id=t4.tenant_id)
order by t1.`resource_pool_id`, t2.`unit_config_id`, t3.unit_id;
14、测试缩容unit
alter resource pool oracle_pool unit_num=1;
等待大概10秒钟，检查资源占用
select a.zone,concat(a.svr_ip,':',a.svr_port) observer, cpu_total, (cpu_total-cpu_assigned) cpu_free,disk_total,(disk_total-disk_assigned) disk_free, round(mem_total/1024/1024/1024) mem_total_gb, round((mem_total-mem_assigned)/1024/1024/1024) mem_free_gb, usec_to_time(b.last_offline_time) last_offline_time, usec_to_time(b.start_service_time) start_service_time
from __all_virtual_server_stat a join __all_server b on (a.svr_ip=b.svr_ip and a.svr_port=b.svr_port) order by a.zone, a.svr_ip;
select t1.name resource_pool_name, t2.`name` unit_config_name, t2.max_cpu, t2.min_cpu, round(t2.max_memory/1024/1024/1024) max_mem_gb, round(t2.min_memory/1024/1024/1024) min_mem_gb, t2.max_disk_size/1024/1024/1024 ,t2.max_session_num,t3.unit_id, t3.zone, concat(t3.svr_ip,':',t3.`svr_port`) observer,t4.tenant_id, t4.tenant_name
from __all_resource_pool t1 join __all_unit_config t2 on (t1.unit_config_id=t2.unit_config_id) join __all_unit t3 on (t1.`resource_pool_id` = t3.`resource_pool_id`)
left join __all_tenant t4 on (t1.tenant_id=t4.tenant_id)
order by t1.`resource_pool_id`, t2.`unit_config_id`, t3.unit_id;
15、配置obproxy
mgr2主机安装obproxy
rpm -ivh obproxy-1.8.4.1-1916278.el7.x86_64.rpm
obproxy会被安装到/opt/taobao/install下，可以做个软连接到obproxy
ln -s obproxy-1.8.4.1 obproxy
su - admin
mkdir -p /home/admin/logs/obproxy/log
mkdir -p /home/admin/logs/obproxy/minidump
16、创建ob集群账户
OBProxy 需要跟后端 OBServer 节点保持通信，使用的是内部账户密码，需要提前在 OB 集群（随便找一台）的sys租户下为OBProxy 创建连接账户和密码。(请复制下面SQL不要改动)。
mysql -h127.1 -uroot@sys -P3881 -p -c -A
Enter password:
CREATE USER proxyro IDENTIFIED BY password '*e9c2bcdc178a99b7b08dd25db58ded2ee5bff050' ;
GRANT SELECT ON *.* to proxyro;
17、在mgr2上启动obproxy
su - admin
cd /opt/taobao/install/obproxy && bin/obproxy -r "172.16.80.57:3881;172.16.80.57:4881;172.16.80.58:3881;172.16.80.58:4881;172.16.80.59:3881;172.16.80.59:4881" -p 3883 -o "enable_strict_kernel_release=false,enable_cluster_checkout=false,enable_metadb_used=false" -c obcc
18、关闭启动测试
停observer
ps -ef|grep observer
kill -9 pid
启动observer
su - admin
for i in {1,2}; do \
echo $i; node="node"[$i]; \
cd /home/admin/$node && /home/admin/$node/bin/observer ; \
sleep 1; \
done
ps -ef|grep observer
19、添加observer扩容zone
三台机器创建目录
su - admin
for i in node3; do \
echo $i; \
