安装TDengine的服务器重启了 导致连接不上

[TDuser_Mk3h_9529]

这是啥问题，我改了配置为localhost啊，服务也重启了

[TDuser_M9rZ_1941 (陈浩然)]

你是不是自己手动设置了 fqdn 是 .

[TDuser_Mk3h_9529]

没有呢 服务器重启后 变成 . 然后报上面的错 就改成localhost

那重新配置一个有意义的fqdn吧，在 hosts文件中：
<192.1.1.5> td-001

在 taos.cfg 中配置
fqdn td-001

firstEp td-001:6030

应该就可以解决问题了。

您好 改了又报这个错误

[TDuser_Mk3h_9529]

您好 改了之后 现在这个报错

[TDuser_OEzS_1621 (叶之航)]

这个错误是没有配置 fqdn 。需要在 /etc/hosts 文件中配置一下fqdn 和关联的IP地址。
