SSH秘钥生成

如果没有代码权限,clone代码的时候会提示

kabdamatoAir:未命名文件夹 lcy$ git clone git@bitbucket.org:xialiuliu/swift.gitCloning into 'swift'...Warning: Permanently added the RSA host key for IP address '104.192.143.2' to the list of known hosts.Permission denied (publickey).fatal: Could not read from remote repository.Please make sure you have the correct access rightsand the repository exists.

如果代码权限为输入密码而不是秘钥，则可以向代码权限管理的人要密码，输入相应密码下载即可

kabdamatoAir:未命名文件夹 lcy$ git clone https://xialiuliu@bitbucket.org/xialiuliu/swift.gitCloning into 'swift'...Password for 'https://xialiuliu@bitbucket.org': remote: Counting objects: 144, done.remote: Compressing objects: 100% (125/125), done.remote: Total 144 (delta 49), reused 0 (delta 0)Receiving objects: 100% (144/144), 54.91 KiB | 0 bytes/s, done.Resolving deltas: 100% (49/49), done.Checking connectivity... done.

正常情况都是要提供秘钥的，进入本机的ssh文件夹，里面有一对默认的公钥和私钥，id_rsa和id_rsa.pub，cat id_rsa.pub文件，将text发送给代码管理人员添加公钥权限，就可正常clone代码了

如果已经有ssh key ，copy 你的key with

cat ~/.ssh/id_rsa.pub | pbcopy
