This article describes a basic installation of a MySQL database server onUbuntu Linux. You might need to install other packages to let applications useMySQL, like extensions for PHP. Check your application documentation fordetails.
Linux Downloads These are supplementary downloads that might be useful for some users to build or run MySQL products on specific operating systems. The information or patches might be obsolete for recent distributions and the version of the operating system you are using. I’ll be covering two ways you can install MySQL in Ubuntu 18.04: Install MySQL from the Ubuntu repositories. Very basic, not the latest version (5.7) Install MySQL using the official repository.

Install MySQL
Install the MySQL server by using the Ubuntu package manager:
The installer installs MySQL and all dependencies.
If the secure installation utility does not launch automatically after the installation completes, enter the following command:
This utility prompts you to define the mysql root passwordand other security-related options, including removing remote accessto the root user and setting the root password.
Allow remote access![]()
If you have iptables enabled and want to connect to the MySQL database fromanother machine, you must open a port in your server’s firewall (the defaultport is 3306). You don’t need to do this if the application that uses MySQLis running on the same server.
Run the following command to allow remote access to the mysql server:
Start the MySQL service
After the installation is complete, you can start the database service byrunning the following command. If the service is already started, a messageinforms you that the service is already running:
Launch at reboot
To ensure that the database server launches after a reboot, run the followingcommand:
Configure interfaces
MySQL, by default is no longer bound to ( listening on ) any remotely accessible interfaces.Edit the “bind-address” directive in /etc/mysql/mysql.conf.d/mysqld.cnf:
Restart the mysql service.
Start the mysql shell
There is more than one way to work with a MySQL server, but this articlefocuses on the most basic and compatible approach, the
mysql shell.
Set the root password
If you logged in by entering a blank password, or if you want to change the rootpassword that you set, you can create or change the password.
If you need to reset the root password later, see Reset a MySQL root password.
View users
MySQL stores the user information in its own database. The name of the databaseis mysql. Inside that database the user information is in a table, adataset, named user. If you want to see what users are set up in the MySQLuser table, run the following command:
The following list describes the parts of that command:

Note: All SQL queries end in a semicolon. MySQL does not process a queryuntil you type a semicolon.
User hosts
The following example is the output for the preceding query:
Users are associated with a host, specifically, the host from which they connect.The root user in this example is defined for localhost, for the IP addressof localhost, and the hostname of the server.You usually need to set a user for only one host, the one from which youtypically connect.
If you’re running your application on the same computer as the MySQLserver, the host that it connects to by default is localhost. Any newusers that you create must have localhost in their host field.
If your application connects remotely, the host entry that MySQL looks foris the IP address or DNS hostname of the remote computer (the one from whichthe client is coming).
Anonymous users
In the example output, one entry has a host value but no username or password.That’s an anonymous user. When a client connects with no username specified,it’s trying to connect as an anonymous user.
You usually don’t want any anonymous users, but some MySQL installationsinclude one by default. If you see one, you should either delete the user(refer to the username with empty quotes, like ‘ ‘) or set a password for it.
Create a database
There is a difference between a database server and a database, even thoughthose terms are often used interchangeably. MySQL is a database server, meaning ittracks databases and controls access to them. The database stores the data, andit is the database that applications are trying to access when they interactwith MySQL.
Some applications create a database as part of their setup process, but othersrequire you to create a database yourself and tell theapplication about it.
To create a database, log in to the
mysql shell and run the following command,replacing demodb with the name of the database that you want to create:
After the database is created, you can verify its creation by running a query tolist all databases. The following example shows the query and example output:
Add a database user
When applications connect to the database using the root user, they usually have more privileges than they need. You can add users that applications can use to connect to the new database. In the following example, a user named demouser is created.
Grant database user permissions
Right after you create a new user, it has no privileges. The user can log in,but can’t be used to make any database changes.
Summary
If you’re just creating a database and a user, you are done. The conceptscovered here should give you a solid start from which to learn more.

Are there are any Linux mysql command line tools that don't require the entire mysql db installation package to be installed?
What I'm trying to do is from server #1 (app server), execute mysql commands that will get executed on server #2 (db server). I do not want to run the db on the local server or to install the full blown mysql db.
