Doris 部署启动 FE 报错：the self host 172.31.26.7 does not equal to the host in ROLE file 172.17.0.1. You need to set 'priority_networks' config in fe.conf to match the host 172.17.0.1

报错信息如下：

java.io.IOException: the self host 172.31.26.7 does not equal to the host in ROLE file 172.17.0.1. You need to set 'priority_networks' config in fe.conf to match the host 172.17.0.1

根据错误提示修改 fe.conf 中的 priority_networks 配置绑定内网IP,重启也不起作用。

解决办法

删除 doris-meta目录下的所有目录及文件，修改 fe.conf 里面的 priority_networks,重启即可解决。
