Ubuntu 1804 installation MySQL 5.7 as an example to give you a very detailed introduction.

Execute the command to install MySQL

Sudo apt install mysql-serversudo apt install mysql-client

After installation, check to see if it starts:

Sudo ps aux | grep mysql

If it is already started, you can see the corresponding information after executing the above command. If it is not started, execute the following command to start mysql:

Sudo service mysql start

In addition, the restart mysql command will be used later. The commands for restarting and shutting down mysql are:

Sudo service mysql restartsudo service mysql stop

After ensuring that mysql starts successfully, you can log in to mysql, but you are not prompted for a user name and password during installation, so you can view a default user name and password in'/ etc/mysql/debian.cnf':

Sudo cat / etc/mysql/debian.cnf

Log in to mysql with user and password:

Mysql-udebian-sys-maint-pZBms1EM5icCfeePV

But the default username and password thieves are hard to remember, so you can add a user named my_name with a password of my_password through the following sql statement:

Show databases;use mysql;update user set authentication_string=PASSWORD ("my_password") where user='my_name';update user set plugin= "mysql_native_password"; flush privileges;exit

After adding users, restart mysql and log in with my_name at this time.

Summary

The above is the problem and solution that the editor introduced to you when Ubuntu 18.04installs MySQL without prompting to enter the password. I hope it will be helpful to you.
