| 配置段 | keeper_server：tcp_port、server_id、log/snapshot 路径、raft_configuration |
|---|---|
| 连接方式 | zookeeper 段指向 Keeper 端口（如 9181）即可 |
| 运维 | 配合 4lw 命令（如 mntr）或 system.zookeeper 表查看状态 |
示例
示例
<keeper_server>
<tcp_port>9181</tcp_port>
<server_id>1</server_id>
<log_storage_path>/var/lib/clickhouse/coordination/log</log_storage_path>
<snapshot_storage_path>/var/lib/clickhouse/coordination/snapshots</snapshot_storage_path>
<raft_configuration>
<server>
<id>1</id>
<hostname>ch-1</hostname>
<port>9234</port>
</server>
</raft_configuration>
</keeper_server>迁移期 ZooKeeper 与 Keeper 可以并存指向同一数据（Keeper 兼容 ZK 协议），切换时先小范围验证。
