問題現象

我這邊執行的pc-ctl命令，這個是tidb的pd命令行工具
命令本地會自行的結果如下：

[root@centos7 ~]# /root/pd-ctl -u 10.226.157.132:2900 region {"count": 1,"regions": [{"id": 2,"start_key": "","end_key": "","epoch": {"conf_ver": 128,"version": 9},"peers": [{"id": 65,"store_id": 28},{"id": 66,"store_id": 11},{"id": 70,"store_id": 31},{"id": 71,"store_id": 4},{"id": 75,"store_id": 6}],"leader": {"id": 70,"store_id": 31},"approximate_size": 4986}] }[root@centos7 ~]#

但是通過ssh遠程執行pd-ctl會卡住

[root@centos7 ~]# ssh root@127.0.0.1 "/root/pd-ctl -u 10.226.157.132:2900 region" The authenticity of host '127.0.0.1 (127.0.0.1)' can't be established. ECDSA key fingerprint is SHA256:yWPZSs92gAknt9ycN17tNs9NBZGIF/RA0PSn9evBx7o. ECDSA key fingerprint is MD5:00:74:b3:d5:bc:2f:14:dc:8a:e6:88:03:12:9f:7f:67.

解決方法

是用ssh -t 就可以了

[root@centos7 ~]# ssh -t root@127.0.0.1 "/root/pd-ctl -u 10.226.157.132:2900 region" root@127.0.0.1's password: {"count": 1,"regions": [{"id": 2,"start_key": "","end_key": "","epoch": {"conf_ver": 128,"version": 9},"peers": [{"id": 65,"store_id": 28},{"id": 66,"store_id": 11},{"id": 70,"store_id": 31},{"id": 71,"store_id": 4},{"id": 75,"store_id": 6}],"leader": {"id": 70,"store_id": 31},"approximate_size": 4986}] }Connection to 127.0.0.1 closed. [root@centos7 ~]#

man ssh 查看-t參數的含義如下：

-t Force pseudo-terminal allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful,e.g. when implementing menu services. Multiple -t options force tty allocation, even if ssh has no local tty.#強制偽終端分配。 這可用于在遠程機器上執行任意基于屏幕的程序，這非常有用，例如 實現菜單服務時。 多個 -t 選項強制分配 tty，即使 ssh 沒有本地 tty。
