https://open.oceanbase.com/answer/detail?id=13700696
练习目的
本次练习目的掌握 OceanBase 集群的手动部署技能，理解进程的相关目录、集群初始化、OBProxy和 OB 集群关系等。
练习条件
有笔记本或服务器，内存至少12G 。
练习内容
请记录并分享下列内容：
- （必选）手动部署一个 OB 单副本集群，包括一个 OBProxy 节点。
- （必选）创建一个业务租户、一个业务数据库，以及一些表等。
- （可选）如果单台服务器内存有32G，或者有三台服务器，改为部署一个 OB 三副本集群，包括一个 OBProxy 节点。
- （可选）如果有三台服务器并且服务器内存有 32 G，可以单服务器内启动 2 个节点，实现 1-1-1 扩容到 2-2-2 。

配置obproxy
https://open.oceanbase.com/articles/1100243
obproxy跟OB集群通信是使用sys租户内的一个内部账户proxyro。这个账户需要创建。
obproxy启动后，默认用 root@proxysys 登录，密码为空。需要改密码（通过proxy参数obproxy_sys_password指定）。
obproxy启动后，还需要修改proxyro的密码（通过proxy参数observer_sys_password指定），设置为跟OB集群里创建的proxyro密码一致才能链接那个OB集群。
-- 启动obproxy，其中-c 对应集群的名称，和前面的observer的启动参数对应。 cd /home/admin/obproxy-3.2.0/ && /home/admin/obproxy-3.2.0/bin/obproxy -r "127.0.0.1:2881" -p 2883 -o "enable_strict_kernel_release=false,enable_cluster_checkout=false,enable_metadb_used=false" -c 20220108 netstat -ntlp | grep obproxy netstat -ntlp | grep 88 ps -ef|grep ob -- 通过obproxy登录，初始密码为空 mysql -h127.1 -uroot@proxysys -P2883 -p alter proxyconfig set obproxy_sys_password='lhr'; alter proxyconfig set observer_sys_password='lhr'; show proxyconfig like '%sys_password%'; mysql -h127.1 -uroot@sys -P2883 -plhr -c -A oceanbase mysql -uroot@sys -plhr -h192.168.66.35 -P12883 select * from oceanbase.__all_server; show full processlist;
