伺服器端建立新使用者

為伺服器安全起見,建立使用者(使用者名稱:yishi):

useradd yishi

設定密碼:

passwd yishi

新增sudo許可權:

usermod -aG wheel yishi

關閉Root的遠端訪問

修改/etc/ssh/sshd_config

PermitRootLogin no

然後:

service sshd restart

開啟SSH的公鑰訪問

$ cat id_rsa.pub >> ~/.ssh/authorized_keys
$ chmod 700 ~/.ssh
$ chmod 600 ~/.ssh/id_rsa 
# Disable password authentication forcing use of keys
PasswordAuthentication no
