不知道你们需要哪些信息，先贴报错吧

，启动方式：USE_DOCKER=true ./start-agent.sh 127.0.0.1 36421532-5c67-42ff-a1e5-2c5e37125855

@zack24q 当启动domain为127.0.0.1的时候，不要使用USE_DOCKER=true ，把127.0.0.1的换成你宿主机的ip

yunheli commented

docker 里面的 127.0.0.1 访问不到你的宿主机，报错是连接不上zookeeper

感谢回复

启动方式改成这样了，还是报一样的错误
./start-agent.sh [宿主机的域名] 36421532-5c67-42ff-a1e5-2c5e37125855

这是nohup里的完整日志（只把域名去掉了）
