After installing mysql using sudo apt-get install mysql-server, no question was asked to me to fill a specific password for root account. Logically, it means password is empty. It is confirmed when I have a look in the /var/log/mysql/error.log where I can find this information =>

You can change the password and set a new root password by doing this :
sudo /usr/sbin/mysqld --skip-grant-tables --skip-networking &
mysql -u root
FLUSH PRIVILEGES;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';skip-grant-tables option enables anyone to connect without a password and with all privileges

What’s your .yaml for mysql look like? I can’t reproduce from your steps, if you’re using a secret then maybe there’s an invisible newline at the end?

It is better to delete the directory once and recreate it or check the permission with the xattr command.
$ ls -l ./db
$ xattr ls ./dbI had a same problem, and after a lot of try I found my solution. When I run first time the docker-composer, I left everything on the original settings like this:
environment: MYSQL_ROOT_PASSWORD: MYSQL_ROOT_PASSWORDThen I change the password, say «docker-compose up» but it was still MYSQL_ROOT_PASSWORD.
My solution was delete the «mysql» docker image from my disk. After that, the docker download everything again BUT also set my password for the root as well. Maybe this is not the best, but I am also a beginner in Docker.
So in nutshell the simple «docker-compose up» does not enough.
This happens when your volume from a directory has wrong permission.
You can fix this letting docker to create directory itself.
You need to fix your docker-compose file:
environment: - MYSQL_ROOT_PASSWORD=sheepversion: '2'
services: mysql: image: mysql:5.7.16 container_name: f_mysql volumes: - ./db:/var/lib/mysql environment: - MYSQL_ROOT_PASSWORD=sheep expose: - '3306'Then with a docker exec -it f_mysql /bin/bash and inside the container mysql -u root -p, using sheep, as the password, will be the only way to connect to the mysql server.
The image entrypoint script will never make changes to a database which is existing. If you mount an existing data directory into var/lib/mysql then MYSQL_ROOT_PASSWORD will have no effect.
Remove all unused volumes: docker volume prune
Remove the volume from your database service: docker volume rm <db_data>
Down containers, remove volumes: docker-compose down --volumes
The format for specifying env variables is correct, you can use either
environment: MYSQL_ROOT_PASSWORD: a_passwordenvironment: - MYSQL_ROOT_PASSWORD=a_passwordFor me the issue was that I’d created the db volume with the random password option set, then disabled that, but hadn’t cleared the volume. So no matter what changes I made to the docker-compose file, the old volume with the old login information was still there.
I had to docker volume ls to find the volume then docker volume rm <name> to remove it. After re-upping, everything worked.

2.9.4 Securing the Initial MySQL Account
The MySQL installation process involves initializing the data
directory, including the grant tables in the
mysql system schema that define MySQL accounts.
For details, see Section 2.9.1, “Initializing the Data Directory”.
This section describes how to assign a password to the initial
root account created during the MySQL
installation procedure, if you have not already done so.
Alternative means for performing the process described in this
section:
A password may already be assigned to the initial account under
these circumstances:
On Windows, installations performed using MySQL Installer give you the
option of assigning a password.Installation using RPM packages generates an initial random
password, which is written to the server error log.Installations using Debian packages give you the option of
assigning a password.For data directory initialization performed manually using
,
generates an initial random
password, marks it expired, and writes it to the server error
log. See Section 2.9.1, “Initializing the Data Directory”.
Start the server if it is not running. For instructions, see
Section 2.9.2, “Starting the Server”.
If the
rootaccount exists with an initial
random password that has been expired, connect to the server
asrootusing that password, then choose a
new password. This is the case if the data directory was
initialized using ,
either manually or using an installer that does not give you
the option of specifying a password during the install
operation. Because the password exists, you must use it to
connect to the server. But because the password is expired,
you cannot use the account for any purpose other than to
choose a new password, until you do choose one.If you do not know the initial random password, look in
the server error log.Connect to the server as
rootusing the
password:$> mysql -u root -p Enter password: (enter the random root password here)Choose a new password to replace the random password:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'root-password';
If the
rootaccount exists but has no
password, connect to the server asroot
using no password, then assign a password. This is the case if
you initialized the data directory using mysqld
—initialize-insecure.Connect to the server as
rootusing no
password:$> mysql -u root --skip-passwordAssign a password:
mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'root-password';
After assigning the root account a password,
you must supply that password whenever you connect to the server
using the account. For example, to connect to the server using the
client, use this command:
$> mysql -u root -p
Enter password: (enter root password here)$> mysqladmin -u root -p shutdown
Enter password: (enter root password here)B.3.3.2 How to Reset the Root Password
If you have never assigned a root password
for MySQL, the server does not require a password at all for
connecting as root. However, this is
insecure. For instructions on assigning a password, see
Section 2.9.4, “Securing the Initial MySQL Account”.
B.3.3.2.1 Resetting the Root Password: Windows Systems
Stop the MySQL server if it is running. For a server
that is running as a Windows service, go to the Services
manager: From the menu, select
, then
, then
. Find the MySQL
service in the list and stop it.If your server is not running as a service, you may need
to use the Task Manager to force it to stop.Create a text file containing the password-assignment
statement on a single line. Replace the password with
the password that you want to use.ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';Save the file. This example assumes that you name the
fileC:\mysql-init.txt.Open a console window to get to the command prompt: From
the menu, select
, then enter
as the command to be run.Start the MySQL server with the
init_filesystem
variable set to name the file (notice that the backslash
in the option value is doubled):C:\> cd "C:\Program Files\MySQL\MySQL Server 8.0\bin" C:\> mysqld --init-file=C:\\mysql-init.txtIf you installed MySQL to a different location, adjust
the command accordingly.To have server output to appear in the console window
rather than in a log file, add the
--consoleoption to the
command.If you installed MySQL using the MySQL Installation
Wizard, you may need to specify a
--defaults-fileoption.
For example:C:\> mysqld --defaults-file="C:\\ProgramData\\MySQL\\MySQL Server 8.0\\my.ini" --init-file=C:\\mysql-init.txtThe appropriate
--defaults-filesetting
can be found using the Services Manager: From the
menu, select
, then
, then
. Find the MySQL
service in the list, right-click it, and choose the
Propertiesoption. ThePathfield contains the
to executable
--defaults-filesetting.After the server has started successfully, delete
C:\mysql-init.txt.
You should now be able to connect to the MySQL server as
root using the new password. Stop the
MySQL server and restart it normally. If you run the server
as a service, start it from the Windows Services window. If
you start the server manually, use whatever command you
normally use.
B.3.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems
Stop the MySQL server if it is running. Locate the
.pidfile that contains the
server’s process ID. The exact location and name of this
file depend on your distribution, host name, and
configuration. Common locations are
/var/lib/mysql/,
/var/run/mysqld/, and
/usr/local/mysql/data/. Generally,
the file name has an extension of
.pidand begins with either
mysqldor your system’s host name.$> kill `cat /mysql-data-directory/host_name.pid`Use backticks (not forward quotation marks) with the
catcommand. These cause the output
ofcatto be substituted into the
killcommand.Create a text file containing the password-assignment
statement on a single line. Replace the password with
the password that you want to use.ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';Start the MySQL server with the
init_filesystem
variable set to name the file:$> mysqld --init-file=/home/me/mysql-init &Other options may be necessary as well, depending on how
you normally start your server. For example,
--defaults-filemay be
needed before the
init_fileargument.After the server has started successfully, delete
/home/me/mysql-init.
You should now be able to connect to the MySQL server as
root using the new password. Stop the
server and restart it normally.
B.3.3.2.3 Resetting the Root Password: Generic Instructions
The preceding sections provide password-resetting
instructions specifically for Windows and Unix and Unix-like
systems. Alternatively, on any platform, you can reset the
password using the client (but this
approach is less secure):
Connect to the MySQL server using the
client; no password is
necessary because the server was started with
--skip-grant-tables:$> mysqlIn the
mysqlclient, tell the server
to reload the grant tables so that account-management
statements work:mysql> FLUSH PRIVILEGES;mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
You should now be able to connect to the MySQL server as
root using the new password. Stop the
server and restart it normally (without the
--skip-grant-tables option
and without enabling the
skip_networking system
variable).
Oracle website seems to imply it only works on 15 and 14.

For whatever reason, the MySQL Workbench that came with 16.04 doesn’t work out of the box with MySQL server, at least for me. I tried using «Local Socket/Pipe» to connect in a number of different ways but to no avail.
The solution is to revert back to native password authentication. You can do this by logging in to MySQL using socket authentication by doing:
sudo mysql -u root
Once logged in:
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';Credit to Miguel Nieto’s blog post for this solution.

Logon to mysql from a terminal session:
$sudo mysqlIf you are able to do this then the auth_socket plugin is enabled and the root account is authenticating using this plugin. Note that this is the default setup when installing mysql on ubuntu after having run the secure installation script.
mysql> CREATE USER 'valerie'@'localhost' IDENTIFIED WITH auth_socket;mysql> GRANT ALL PRIVILEGES ON *.* TO 'valerie'@'localhost' WITH GRANT OPTION;Exit the shell:
mysql> exitThen in mysql workbench:
- Create a new connection
- Select the connection method as Local Socket/Pipe
- Set the Socket/Pipe Path to: /var/run/mysqld/mysqld.sock (note that this is the path for a Debian / Ubuntu system and changes for other flavors of Linux)
- Set the username (‘valerie’ in this example)
You should be able to then connect to the mysql server with this connection.

MySQL server on AWS host running Ubuntu 16.04; mysql-workbench on Ubuntu 16.04 laptop; uses KeyPair connection.
After setting up Test db connection was working.
But the actual connection always failed with a message like the one posted by Jonathan Leaders.
Checked the log at ~/.mysql/workbench/log and found a few «permission denied» messages.
Now I can get mysql-workbench to work with:
sudo mysql-workbench
And later I can go and chmod the directories needing permission.
