CentOS 7 SSH使用证书登录(git更新免密)

本地生成证书:

ssh-keygen -t rsa

会提示输入密码全部回车，不设置密码

~/.ssh/目录下会生成两个文件:
id_rsa为私钥，id_rsa.pub为公钥.

把id_rsa.pub传到centos7服务器上

scp -r id_rsa.pub git@192.168.1.1:~/

导入公钥

cat ~/id_rsa.pub >> ~/.ssh/authorized_keys

服务器上配置ssh，用root账号配置:

RSAAuthentication yes
StrictModes no
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys

重启ssh

systemctl restart sshd.service
