hostname如果包含短横线-,则启动失败.

比如, 我的hostname是: tdengine-1, 则启动时报错:

06/08 15:49:11.056342 00000593 C DND start to init dnode env
06/08 15:49:11.057625 00000593 C DND dnode file:/var/lib/taos//dnode/dnode.json not exist

此时需修改:

1. hostname: hostnamectl set-hostname tdengine1;
2. /etc/taos/taos.cfg: 配置文件中如设置了hostname, 也需同步修改;
3. /etc/hosts: 新hostname的IP地址解析也需同步修改.

以此记录供后来者参考.

我这边试了一下，用- 的FQDN 可以用的。
