1. 启动doris
1.1 一台fe 三台be
[root@node01 bin]# ./start_fe.sh --daemon
[root@node01 bin]# ./start_be.sh --daemon
[root@node02 bin]# ./start_be.sh --daemon
[root@node03 bin]# ./start_be.sh --daemon
1.2 连接 doris
[root@node01 bin]# mysql -h 192.168.1.161 -P9030 -uroot
mysql> create database wudl_db;
Query OK, 0 rows affected (0.01 sec)
mysql> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| test |
| test_db |
| wudl_db |
+--------------------+
1.3 创建表
mysql> CREATE TABLE `doris_test` (
-> `id` int NULL COMMENT "id",
-> `name` varchar(40) NULL COMMENT "名称"
-> ) ENGINE=OLAP
-> DUPLICATE KEY(`id`)
-> COMMENT "OLAP"
-> DISTRIBUTED BY HASH(`id`) BUCKETS 1
-> PROPERTIES (
-> "replication_num" = "1",
-> "in_memory" = "false",
-> "storage_format" = "V2"
-> );
Query OK, 0 rows affected (0.06 sec)
1.4 插入数据
mysql> insert into doris_test (id,name) values(1,'hdfs');
Query OK, 1 row affected (0.07 sec)
{'label':'insert_683fe77d679648be-b9440896f330d70c', 'status':'VISIBLE', 'txnId':'30'}
2.通过接口(Spring boot mybatis)的方式访问 数据

4. 总结
总的来说doris 可以当做一个mysql 数据库用mybatis 来操作， 因为他支持mybatis 协议。
