1.git每次push/pull时，当push或pull方式为http时，解决频繁输入账户名密码问题
git config --global credential.helper store然后在push或pull，第一次需要密码，往后就不需要了#最后会在这个路径下生成你git相关信息cat ~/.git-credentialshttps://zhd-haodong:密码@
2.git当push/pull方式为ssh时,解决git@:Permission denied (publickey)问题
#生成公钥ssh-keygen -t rsa -C 'zhang**@**.cn'#将公钥copy到GitHub-settings-SSH即可cat ~/.ssh/id_rsa.pubssh-rsa 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 zhanghaodong@
