1. 创建一个无密码的密钥

mkdir -p ~/.ssh
chmod 700 ~/.ssh
cd ~/.ssh
ssh-keygen -t rsa

 

将公钥拷贝到客户端这里用rsync方法
rsync id_rsa.pub root@xx.xx.xx.xx:/root/.ssh/.

cat id_rsa.pub >> authorized_keys

 

① 在资产上生成 root 账户的公钥和私钥

[root@centos7-1 ~]# ssh-keygen -t rsa   # 默认会输入公钥和私钥文件到 ~/.ssh 目录

② 将公钥输出到文件 authorized_keys 文件，并修改权限

 cat ~/.ssh/id_rsa22.pub >> ~/.ssh/authorized_keys

 chmod 400 ~/.ssh/authorized_keys

③ 打开RSA验证相关设置

[root@centos7-1 ~]# vim /etc/ssh/sshd_config

  RSAAuthentication yes
  PubkeyAuthentication yes
  AuthorizedKeysFile     .ssh/authorized_keys

④ 重启 ssh 服务

[root@centos7-1 ~]# systemctl restart sshd

⑤ 上传 ~/.ssh 目录下的 id_rsa 私钥到 jumpserver 的管理用户中

安装rz sz

yum -y install lrzsz

cat /etc/passwd 可以查看所有用户的列表

登录到机器上

mkdir -p /home/web

chmod -R 777 /home/web
