RT 每个机子一个密钥批量控制太麻烦了

sudo -i echo root:要修改的密码 |sudo chpasswd root sudo sed -i ‘s/^.*PermitRootLogin.*/PermitRootLogin yes/g’ /etc/ssh/sshd_config; sudo sed -i ‘s/^.*PasswordAuthentication.*/PasswordAuthentication yes/g’ /etc/ssh/sshd_config; sudo service sshd restart

为什么不行？

当然可以

善用搜索，这是可行的

#编辑cloud.cfg vim /etc/cloud/cloud.cfg #在最后加入以下代码 #!/bin/bash echo root:你的密码 |sudo chpasswd root sudo sed -i ‘s/^#?PermitRootLogin.*/PermitRootLogin yes/g’ /etc/ssh/sshd_config; sudo sed -i ‘s/^#?PasswordAuthentication.*/PasswordAuthentication yes/g’ /etc/ssh/sshd_config; sudo service sshd restart

dd就行

你发工单问问，看看客服怎么回复
