ssh 证书登录

1. 生成证书

         ssh-keygen -t rsa

         生成两个文件，密钥：id_rsa，公钥：id_rsa.pub

         拷贝公钥到authorized_keys： cp /root/.ssh/id_rsa.pub /root/.ssh/authorized_keys

         

2. 修改sshd_config

PermitRootLogin yes

RSAAuthentication yes

PubkeyAuthentication yes

AuthorizedKeysFile     .ssh/authorized_keys

重启ssh服务 service sshd restart

 

3. 拷贝私钥id_rsa到客户机，在客户机使用id_rsa连接到目标机

          ssh -i id_rsa [email protected]
