VPS啓用root密碼登錄(Enable ssh login as root with password)

有些VPS商家不會提供默認root賬戶和密碼，有些命令只能通過 sudo su 來提權，可通過以下方法設置root賬戶登錄。 (Some VPS providers do not provide a default root account and password. Some commands can only be executed with elevated privileges using sudo su. You can set up a root account login using the following method:)

sudo sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin yes/g' /etc/ssh/sshd_config
sudo sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication yes/g' /etc/ssh/sshd_config

然後重置密碼(Then set our password for root)

passwd root

重啓ssh服務(Restart sshd service)

sudo service sshd restart
