server_protocol

更新时间：2026-07-22 16:50:58

分享

说明

该配置项自 4.3.4 版本开始引入。

功能描述

server_protocol 用于控制 ODP 与 OceanBase 数据库之间的协议类型。

属性说明

属性	描述
参数类型	字符串类型
默认值	Auto
取值范围	可配置为 `Auto`、`MySQL`、`Compressed MySQL`、`OceanBase 2.0`，不区分大小写。不同取值的具体含义如下： `Auto`：当 `enable_single_leader_node_routing` 配置为 `True` 时，在租户 Leader 副本聚集的场景下，对应租户的连接使用 MySQL 协议，其他场景使用 OceanBase 2.0 协议。当 `enable_single_leader_node_routing` 配置为 `False` 时，所有租户均使用 OceanBase 2.0 协议。 `MySQL`：强制使用 MySQL 协议。 `Compressed MySQL`：强制使用压缩协议，不建议配置为该值，OceanBase 2.0 协议也具有压缩数据功能，有压缩数据需求时直接使用 OceanBase 2.0 协议即可。 `OceanBase 2.0`：强制使用 OceanBase 2.0 协议。
是否重启 ODP 生效	否，重建连接即生效

配置示例

设置 ODP 与 OceanBase 数据库之间强制使用 MySQL 协议。

obclient> alter proxyconfig set server_protocol='MySQL';
