Sudo /usr/sbin/mysqld -skip-grant-tables -skip-networking & In Ubuntu 18.04 there was a good tutorial (several): SERVER BEENDEN: But that's another story.It is always a problem to get the root password to login to the localhost/phpmyadmin. The CCP has been stealing data from anywhere it can for decades. You may be surprised to see how quickly they start trying to shell into your server. To see who is attacking you use this command: I also only use ipv4 so I lockout ipv6 access via the sshd_config file, the /etc/default/ufw file, and the /etc/default/grub file. No other ports are opened to allow any other access but ssh. You have now locked out everyone trying to shell into your root and updated your Ubuntu files. Ssh soon as you have created your server, do this: I store my login data like this in a text file on my primary computer: Use special characters like $%& and don't use any words or phrases. Use all of the character keys on the keyboard in a random selection except the backtick ' key. Do not duplicate keys next to each other. It should be at least 32 characters long. As fast as you setup the server, someone will be trying to hack in!Ĭreate a strong root password. When I first learned how to setup an unattended Ubuntu server, I discovered several important things. I have an instance on RamNode I use for my websites. We only worry about the hackers out there. Let's face it, if a government wants into your server, they will use an easy way to see your files. I would suggest not doing that but doing things to maximize security. When to disable root account on ubuntu server? This is probably why your cloud image comes with root enabled and no separate administrative user. Having said all this, on a system with a single administrator, logging who uses sudo is less interesting, and if you have cloud images that you can just zap and reload from a fresh copy, what user you run things as inside the container is also less important. Most applications should not be run as root directly. The design philosophy behind this is that the application is isolated within its own user, and security issues with the application will (hopefully) be trapped in that user id. ) so that it runs with the correct permissions in the correct environment. You should not be starting the application by hand, but allowing the installed system scripts to start it (for instance with systemctl start. This user is created when the application is installed. When an application (like NginX, mysql, mogodb, etc.) is configured to start at boot, typically the systemd (or initd) boot scripts start the application as a special application user. So installing software is still done as root - just via sudo instead of direct login. This also has the side effect that when you use sudo, the user account that did this is also logged, which is not that interesting unless there are multiple user accounts that can use sudo, in which case, it is easier to assign blame when a mistake is made. Then you use sudo to elevate to root to install software and do other dangerous things. The point of disabling the root account is so that you log in as a normal user and do user session like things as a normal user and not root. Disabling login for the root account doesn't change this, and it doesn't change how applications are started at boot. Sometimes application software is installed as an application specific user, but typically not. System software is always installed as root. The reason for "disabling root" and using sudo with a regular account instead has multiple purposes, none of which affect the answer to your question. Disable root ssh in due course to protect against brute force attacks.Root account and/or sudo user accounts, because these applications should run with their own default user accounts. Web applications (node, pm2, mongo) can be installed EITHER with.A Sudo user can be tracked who performed actions (of relevance when multiple users are concerned).A Sudo user has the same privileges as root.UPDATE1: Thanks for your assistance all, I've updated the question and added its a cloud install. Then create a second admin user with ssh access and then disable ssh for root? Should I instead use root user to set-up all applicatons first, and allow applications to run under root ? In order, I created a new user and then used this to set-up all applications but ran into issue with nginx. In several articles there is mention of disabling root user to improve security and create a new user with administration access. I've set up Ubuntu 20.xx as a web server in the cloud provided by Digital Ocean and wish to install Node, Express, Mongo and possibly NginX.
