使用mina部署rails应用时遇到的问题们

无法从github拉取代码

—–> Cloning the Git repository

Cloning into bare repository ‘/home/XXX/app/scm’…

Host key verification failed.

fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

! ERROR: Deploy failed.

原因：Accessing the repo via SSH requires the target machine to have public key

to be uploaded to GitHub.

解决方法： github信息加入~/.ssh/known_hosts

RVM安装之后，新的会话不生效，需要source

原因：~/.bashrc与~/.bash_profile没有区别清楚

解决方法：

[[ -s "/usr/local/rvm/scripts/rvm" ]] && . "/usr/local/rvm/scripts/rvm"

将以上内容加入~/.bashrc
