当前 tidb 4.0.rc1 tiup最新 打算扩容一个tikv节点，ssh ntpd服务 都正常，防火墙已关闭，slinux也已关闭 scale-out.yaml 配置如下
tikv_servers:
- host: 172.7.160.26
ssh_port: 23
imported: true
port: 20160
status_port: 20180
deploy_dir: /data/deploy
data_dir: /data/deploy/data
log_dir: /data/deploy/log
在 /home/tidb/ 目录下，使用 tidb 用户在此目录下执行
tiup cluster scale-out 集群名 scale-out.yaml
几次都报错如下
