**第一步**:如果搭建集群的物理节点中,存有之前的测试数据、装过1.X的版本,或者装过其他版本的TDengine,请先将其删除,并清空所有数据(如果需要保留原有数据,请联系涛思交付团队进行旧版本升级、数据迁移),具体步骤请参考博客[《TDengine多种安装包的安装和卸载》](https://www.taosdata.com/blog/2019/08/09/566.html)
**注意1:**因为FQDN的信息会写进文件,如果之前没有配置或者更改FQDN,且启动了TDengine。请一定在确保数据无用或者备份的前提下,清理一下之前的数据(`rm -rf /var/lib/taos/*`);
**注意2:**客户端也需要配置,确保它可以正确解析每个节点的FQDN配置,不管是通过DNS服务,还是 Host 文件。
**注意2:**客户端也需要配置,确保它可以正确解析每个节点的FQDN配置,不管是通过DNS服务,还是修改 hosts 文件。
**第二步**:建议关闭所有物理节点的防火墙,至少保证端口:6030 - 6042的TCP和UDP端口都是开放的。**强烈建议**先关闭防火墙,集群搭建完毕之后,再来配置端口;

**Note 1:** Because the information of FQDN will be written into a file, if FQDN has not been configured or changed before, and TDengine has been started, be sure to clean up the previous data (`rm -rf /var/lib/taos/*`)on the premise of ensuring that the data is useless or backed up;
**Note 2:** The client also needs to be configured to ensure that it can correctly parse the FQDN configuration of each node, whether through DNS service or Host file.
**Note 2:** The client also needs to be configured to ensure that it can correctly parse the FQDN configuration of each node, whether through DNS service or modify hosts file.
**Step 2:** It is recommended to close the firewall of all physical nodes, and at least ensure that the TCP and UDP ports of ports 6030-6042 are open. It is **strongly recommended** to close the firewall first and configure the ports after the cluster is built;
