【问题澄清】
- ansible 部署 dm/tidb 集群，执行到通过 ansible 命令验证 tidb 用户时报错：
FAILED! => { “changed”: false, “module_stderr”: “Shared connection to 10.8.14.100 closed.\r
”, “module_stdout”: “/bin/sh: /usr/bin/python: No such file or directory\r

【原因分析】
- 可以看到具体的报错信息为（上文已经突出显示）：
/bin/sh: /usr/bin/python: No such file or directory
【解决方案】
- 将该路径 ln 到 python2.7 的位置，或者安装 python2.7
