In daily use of Cloud Server, we often encounter that the server cannot obtain root privileges, especially the Ubuntu system. At the beginning of the system, you will be asked to use a custom name, similar to windows10, let you create one yourself An account is not a reason to use an Administrator account, but it is often useless to create an account by yourself. Especially when developers are developing projects, they often lead to insufficient permissions and unable to edit. Then I will solve this problem for everyone Right!
In fact, this problem is relatively simple. The main reason is that SSH improves the protection of the system to avoid unauthorized access. As long as you find the SSH configuration file and modify some, you can use the Root account to operate by default. Okay, not much nonsense ,start to act.
Under normal circumstances, do you first log in to the ubuntu system with the account you created, and then use the su root command to switch to root? In fact, it doesn't have to be so troublesome, just follow my method.
If you are the first to use it, please specify a password for the root account for easy access:
sudo passwd root
root@VM-0-3-ubuntu:/# sudo passwd root
Enter newUNIX password:
Retype newUNIX password:
passwd: password updated successfully
root@VM-0-3-ubuntu:/#
sudo vi /etc/ssh/sshd_config
Find the item PermitRootLogin and change it to yes
# Authentication:
LoginGraceTime 120
PermitRootLogin yes
StrictModes yes
Save and restart the ssh service:
sudo service ssh restart
Okay, now you can directly use the root account to operate your own projects and see if you succeeded. If you have any questions, please leave a message in the comment area below, thank you!
