接手的集群，怀疑是之前有人升级过该集群，导致的配置信息错乱。

3

重新做一遍免密互信吧。

4

或者建上tidb 用户，scale-out 时加上-utidb -p 应该也可以

6

通过tidb用户可以ssh到目标机器，不是互信导致的吧。。

7

ssh的时候要输入密码么？ 需要免密互信。

8

不需要

9

ssh_stderr: invalid configuration: entity not found\n, ssh_stdout: , ssh_command: export LANG=C; PATH=$PATH:/bin:/sbin:/usr/bin:/usr/sbin /data/tidb/deploy/tikv-20160/bin/tikv-server --config-check --config=/data/tidb/deploy/tikv-20160/conf/tikv.toml --pd “” --data-dir “/data/tidb/data/tikv-20160”

应该是 tikv 配置文件里有些非法参数，检查下 tikv 参数配置文件吧

10

是的，不知道哪来的脏配置，严重怀疑升级过。。。导致配置文件错乱。

11

去要扩容的实例上检查 tikv.toml 发现有非标配置，直接手动创建目录并修改权限，tiup扩容正常了。

12

报错中提示有无效的配置：invalid configuration，可以通过 /data/tidb/deploy/tikv-20160/bin/tikv-server --config-check --config=/data/tidb/deploy/tikv-20160/conf/tikv.toml 命令进行检测配置文件是否有错误的地方

13

配置文件问题
