You should use a non-root user account as explained in the Ubuntu 18.04 Initial Server Setup.
1. Install MySQL
Let’s begin by updating the package lists and installing MySQL on Ubuntu 18.04. Below we have two commands separated by
&&. The first command will update the package lists to ensure you get the latest version and dependencies for MySQL. The second command will then download and install MySQL.
sudo apt update && sudo apt install mysql-server
ENTER when prompted to install the MySQL package.
Once the package installer has finished, we can check to see if the MySQL service is running.
sudo service mysql status
If running, you will see a green Active status like below.
● mysql.service - MySQL Community Server Loaded: loaded (/lib/systemd/system/mysql.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2018-04-02 02:40:59 CEST; 2min 47s ago Main PID: 18476 (mysqld) Tasks: 27 (limit: 4915) CGroup: /system.slice/mysql.service └─18476 /usr/sbin/mysqld --daemonize --pid-file=/run/mysqld/mysqld.pid Apr 02 02:40:59 ubuntu1804 systemd: Starting MySQL Community Server... Apr 02 02:40:59 ubuntu1804 systemd: Started MySQL Community Server.
You may need to press
q to exit the service status.
2. Configure Security
You should now run
mysql_secure_installation to configure security for your MySQL server.
If you created a root password in Step 1, you may be prompted to enter it here. Otherwise you will be asked to create one. (Generate a password)
You will be asked if you want to set up the Validate Password Plugin. It’s not really necessary unless you want to enforce strict password policies for some reason.
Securing the MySQL server deployment. Connecting to MySQL using a blank password. VALIDATE PASSWORD PLUGIN can be used to test passwords and improve security. It checks the strength of password and allows the users to set only those passwords which are secure enough. Would you like to setup VALIDATE PASSWORD plugin? Press y|Y for Yes, any other key for No:
ENTER here if you don’t want to set up the validate password plugin.
Please set the password for root here. New password: Re-enter new password:
If you didn’t create a root password in Step 1, you must now create one here.
Generate a strong password and enter it. Note that when you enter passwords in Linux, nothing will show as you are typing (no stars or dots).
By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL without having to have a user account created for them. This is intended only for testing, and to make the installation go a bit smoother. You should remove them before moving into a production environment. Remove anonymous users? (Press y|Y for Yes, any other key for No) :
ENTER to remove anonymous users.
Normally, root should only be allowed to connect from 'localhost'. This ensures that someone cannot guess at the root password from the network. Disallow root login remotely? (Press y|Y for Yes, any other key for No) :
ENTER to disallow root login remotely. This will prevent bots and hackers from trying to guess the root password.
By default, MySQL comes with a database named 'test' that anyone can access. This is also intended only for testing, and should be removed before moving into a production environment. Remove test database and access to it? (Press y|Y for Yes, any other key for No) :
ENTER to remove the test database.
Reloading the privilege tables will ensure that all changes made so far will take effect immediately. Reload privilege tables now? (Press y|Y for Yes, any other key for No) :
ENTER to reload the privilege tables.
As a test, you can log into the MySQL server and run the
sudo mysqladmin -p -u root version
Enter the MySQL root password you created earlier and you should see the following:

You have now successfully installed and configured MySQL for Ubuntu 18.04!
Now that your MySQL server is up and running, you might want to install phpMyAdmin, which allows you to easily manage your MySQL users and databases through a browser interface. Before installing phpMyAdmin, you must have Apache/Nginx and PHP installed first. Please refer to the following guides:
- Installing Apache on Ubuntu 18.04 with Virtual Hosts
- Installing PHP for Apache on Ubuntu 18.04 Server
- Installing phpMyAdmin for Apache on Ubuntu 18.04
- Installing Nginx on Ubuntu 18.04 with Multiple Domains
- Installing PHP for Nginx on Ubuntu 18.04
- Installing phpMyAdmin for Nginx on Ubuntu 18.04
Let me know if this helped. Follow me on Twitter, Facebook and YouTube, or 🍊 buy me a smoothie.
p.s. I increased my AdSense revenue by 200% using AI 🤖. Read my Ezoic review to find out how.
Not sure if this is the right place to ask this, but how do I allow multiple sites to access the MySQL database? I have 3 sites hosted on my server, but can’t get any of them to create a new database from a install script (php). I have Nginx+MySQL+PHP+PHPmyAdmin all set up, but am at a loss as how to get each one to use the MySQL.
I’ve tried Googling it, but all I ever get is how to install each one. Nothing about allowing multiple access.
If MySQL is on the same server as your sites, then it is just
localhost. There is no special setup.
Are you able to connect to port
If you can, I would create a test database and user in phpMyAdmin, then do a test connection in PHP to see if you can connect.
databasewith your own details.
Thanks for getting back. I created the test DB, and created a php file with the test and ran it. Got a blank page, so I’m assuming it was successful.
I feel like an idiot right now…cause the reason the install script wasn’t working (wait for it………) was because I forgot to create the database in PHPmyAdmin first. DOH! LMAO
Thanks for your help. 🙂
It didn’t work for me, after the sudo mysql_secure_installation command, and supplying a root password, the computer responded … Failed! Error: Table ‘mysql.role_edges’ doesn’t exist. What went wrong?
What happens if you run
Thanks for your reaction, after running the command you proposed, the computer responds:
Checking if update is needed.
Checking server version.
Running queries to upgrade MySQL server.
mysql_upgrade: [ERROR] 3009: Column count of mysql.user is wrong. Expected 49, found 45. Created with MySQL 80011, now running 80012. Please use mysql_upgrade to fix this error.
It sounds like the db might be corrupted.
If that fails, I would recommend removing MySQL completely and starting from scratch. These commands will wipe any databases you have so run at your own risk.
Then follow this guide again to install MySQL.
Yesss, now it is fixed thank you!
btw: the command was sudo mysql_upgrade –force root -p (so without minus sign before the word root)
Ah, sorry about the dash!
Great you got it sorted in the end.
Congratulations, thank you very much, my friend, for sharing your knowledge.
I have installed mysql 5.7. After installation mysql enters without password. How to change it??
The password doesn’t seem to work, and I’m having the same problem
