Linux mysql default password

Linux mysql default password

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 2.10.1, “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:

On Windows, you can perform the process during installation with MySQL Installer (see Section 2.3.3, “MySQL Installer for Windows”).

On all platforms, the MySQL distribution includes mysql_secure_installation , a command-line utility that automates much of the process of securing a MySQL installation.

On all platforms, MySQL Workbench is available and offers the ability to manage user accounts (see Chapter 31, MySQL Workbench ).

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 the macOS installer generates an initial random password, which the installer displays to the user in a dialog box.

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 mysqld —initialize , mysqld generates an initial random password, marks it expired, and writes it to the server error log. See Section 2.10.1, “Initializing the Data Directory”.

The mysql.user grant table defines the initial MySQL user account and its access privileges. Installation of MySQL creates only a ‘root’@’localhost’ superuser account that has all privileges and can do anything. If the root account has an empty password, your MySQL installation is unprotected: Anyone can connect to the MySQL server as root without a password and be granted all privileges.

The ‘root’@’localhost’ account also has a row in the mysql.proxies_priv table that enables granting the PROXY privilege for »@» , that is, for all users and all hosts. This enables root to set up proxy users, as well as to delegate to other accounts the authority to set up proxy users. See Section 6.2.18, “Proxy Users”.

To assign a password for the initial MySQL root account, use the following procedure. Replace root-password in the examples with the password that you want to use.

Start the server if it is not running. For instructions, see Section 2.10.2, “Starting the Server”.

The initial root account may or may not have a password. Choose whichever of the following procedures applies:

If the root account exists with an initial random password that has been expired, connect to the server as root using that password, then choose a new password. This is the case if the data directory was initialized using mysqld —initialize , 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 root using the password:

Choose a new password to replace the random password:

If the root account exists but has no password, connect to the server as root 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 root using no password:

Assign a 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 mysql client, use this command:

To shut down the server with mysqladmin , use this command:

For additional information about setting passwords, see Section 6.2.14, “Assigning Account Passwords”. If you forget your root password after setting it, see Section B.3.3.2, “How to Reset the Root Password”.

How do I find out my root MySQL password?

I just installed MySQL on Ubuntu and the root user can’t log in 🙂

How can I recover or find out my password? Using blank for password does not work.

You can reset the root password by running the server with —skip-grant-tables and logging in without a password by running the following as root (or with sudo):

Now you should be able to login as root with your new password.

It is also possible to find the query that reset the password in /home/$USER/.mysql_history or /root/.mysql_history of the user who reset the password, but the above will always work.

Note: prior to MySQL 5.7 the column was called password instead of authentication_string . Replace the line above with

I realize that this is an old thread, but I thought I’d update it with my results.

Alex, it sounds like you installed MySQL server via the meta-package ‘mysql-server’. This installs the latest package by reference (in my case, mysql-server-5.5). I, like you, was not prompted for a MySQL password upon setup as I had expected. I suppose there are two answers:

Solution #1: install MySQL by it’s full name:

Solution #2: reconfigure the package.

You must specific the full package name. Using the meta-package ‘mysql-server’ did not have the desired result for me. I hope this helps someone 🙂

MySQL 5.5 on Ubuntu 14.04 required slightly different commands as recommended here. In a nutshell:

And then from the MySQL prompt

And the cited source offers an alternate method as well.

For RHEL-mysql 5.5:

Hmm Mysql 5.7.13 to reset all I did was:

$ sudo service mysql stop To stop mysql

$ mysqld_safe —skip-grant-tables & Start mysql

Just like the correct answer. Then all I did was do what @eebbesen did.

mysql> SET PASSWORD FOR root@’localhost’ = PASSWORD(‘NEW-password-HERE’);

Hope it helps anyone out there 🙂

Here is the best way to set your root password : Source Link Step 3 is working perfectly for me.

Commands for You

1. sudo mysql
2. SELECT user,authentication_string,plugin,host FROM mysql.user;
3. ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘password’;
4. FLUSH PRIVILEGES;
5. SELECT user,authentication_string,plugin,host FROM mysql.user;
6. exit

Now you can use the Password for the root user is ‘password‘ :

1. mysql -u root -p
2. CREATE USER ‘sammy’@’localhost’ IDENTIFIED BY ‘password’;
3. GRANT ALL PRIVILEGES ON . TO ‘sammy’@’localhost’ WITH GRANT OPTION;
4. FLUSH PRIVILEGES;
5. exit

Test your MySQL Service and Version:

Under MYSQL 5.7, If you are using mysql for development purpose, just :

2.start mysql under —skip-grant-tables mode:

and, further, you could try to change the user table under «skip-grant-table» mode, however I failed.

so, this is just a workaround.

There is a simple solution.

MySql 5.7 comes with anonymous user so you need to reconfigure MySQL server.

You can do that with this command

try to find temp pass:

On this link is more info about mysql 5.7

It is actually very simple. You don’t have to go through a lot of stuff. Just run the following command in terminal and follow on-screen instructions.

I’m going to make a bit of an assumption here because I’m not sure. I don’t think my MySQL (running on latest 20.04 upgraded) even has a root. I have tried setting one and I remember having problems. I suspect there is not a root user and it will automatically log you in as the MySQL root user if you’re logged in as root.

Why do I think this? Because when I do MySQL -u root -p, it will accept any password and log me in as the MySQL root user when I am logged in as root.

I have confirmed that trying that on a non root user doesn’t work.

I like this model.

EDIT 2020.12.19: It is no longer a mystery to me why if you are logged in as the root user you get logged into MySQL as the root user. It has to do with the authentication type. Later versions of MySQL are configured with the MySQL plugin ‘auth_socket’ (maybe you’ve noticed the /run/mysqld/mysqld.sock file on your system and wondered about it). The plugin uses the SO_PEERCRED option provided by the library auth_socket.so.

You can revert back to password authentication if desired simply by create/update of the password. Showing both ways and options below to make clear.

CREATE USER ‘valerie’@’localhost’ IDENTIFIED WITH auth_socket;
CREATE USER ‘valerie’@’localhost’ IDENTIFIED BY ‘password’;

Default password of mysql in ubuntu server 16.04

I have installed ubuntu 16.04 server. Mysql server was installed by default in it. When I am trying to access the mysql with mysql -u root -p , I am unable to log in to mysql because I dont have the password. Is there any default password?

I have also tried with —skip-grant-tables , even this does not work. Even trying to log in with just mysql -u root is a failure.

This is what you are looking for:
sudo mysql —defaults-file=/etc/mysql/debian.cnf
MySql on Debian-base Linux usually use a configuration file with the credentials.

I had a fresh installation of mysql-server on Ubuntu 18.10 and couldn’t login with default password. Then only I got to know that by default root user is authenticated using auth_socket . So as in the answer when the plugin changed to mysql_native_password , we can use mysql default password

You can find the following lines in there

type the password from debian.cnf

—Update—

Sometimes you will need to restart your mysql server.

Mysql by default has root user’s authentication plugin as auth_socket , which requires the system user name and db user name to be the same.

Specifically, log in as root or sudo -i and just type mysql and you will be logged in as mysql root , you can then create other operating users.

If you do not have a root on host, I guess you should not be allowed to login to mysql as root?

You can simply reset the root password by running the server with —skip-grant-tables and logging in without a password by running the following as root or with sudo:

Although this is an old question, there are several of us still struggle to find an answer. At least I did. Please don’t follow all the lengthy solutions. You could simply login to your mysql as root without providing any password (provided it is a fresh installation or you haven’t changed the password since your installation) by adding sudo before your mysql command. $sudo mysql -uroot -p mysql> This is because mysql changed the security model in one of the latest versions.

Hope this helps

Note that in Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. you will need to switch its authentication method from auth_socket to mysql_native_password

as @BeNiza said, they changed the security model. I did following steps and it works for mysql 5.7.27 on ubuntu 18.04

sudo apt install mysql-server

The MySQL database software is now installed, but its configuration is not yet complete.

To secure the installation, MySQL comes with a script that will ask whether we want to modify some insecure defaults. Initiate the script by typing:

you should press Y and hit the ENTER key at each prompt.

This will cause issues if you use a weak password

You can simply login to your mysql as root without providing any password by adding sudo before your mysql command.

mysql> ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘your-password’;

If you set a weak password you would see the following error:

ERROR 1819 (HY000): Your password does not satisfy the current policy requirements

mysql> FLUSH PRIVILEGES;

Note: After configuring your root MySQL user to authenticate with a password, you’ll no longer be able to access MySQL with the sudo mysql command used previously. Instead, you must run the following: mysql -u root -p

After entering the password you just set, you will see the MySQL prompt.

What is the default root pasword for MySQL 5.7

Cannot login to MySQL database after fresh install with root ID and empty/no password like other older MySQL versions do

14 Answers 14

There’s so many answers out there saying to reinstall mysql or use some combo of

and / or something else .

. None of it was working for me

Here’s what worked for me, on Ubuntu 18.04, from the top

With special credit to this answer for digging me out of the frustration on this .

Note the lines which read:

After you installed MySQL-community-server 5.7 from fresh on linux, you will need to find the temporary password from /var/log/mysqld.log to login as root.

1. grep ‘temporary password’ /var/log/mysqld.log
2. Run mysql_secure_installation to change new password

MySQL 5.7 changed the secure model: now MySQL root login requires a sudo

The simplest (and safest) solution will be create a new user and grant required privileges.

1. Connect to mysql

2. Create a user for phpMyAdmin

MySQL server 5.7 was already installed by default on my new Linux Mint 19.

But, what’s the MySQL root password? It turns out that:

The default installation uses auth_socket for authentication, in lieu of passwords!

It allows a password-free login, provided that one is logged into the Linux system with the same user name. To login as the MySQL root user , one can use sudo:

But how to then change the root password? To illustrate what’s going on, I created a new user «me», with full privileges, with:

Comparing «me» with «root»:

Because it’s using auth_socket, the root password cannot be changed: the SET PASSWORD command fails, and mysql_secure_installation desn’t attain anything.

==> To zap this alternate authentication mode and return the MySQL root user to using passwords:

In case you want to install mysql or percona unattended (like in my case ansible), you can use following script:

MySQL 5.7 or newer generates a default temporary password after fresh install.

To use MySQL first you would be required to get that password from the log file which is present at the /var/log/mysqld.log . So follow the following process:

grep ‘temporary password’ /var/log/mysqld.log

The second command is required to change the password for MySQL and also to make certain other changes like removing temporary databases, allow or disallow remote access to root user, delete anonymous users etc…

It seems things were designed to avoid developers to set the root user, a better solution would be:

Then create a normal user, set a password, then use that user to work.

Then try to access:

None of these answers worked for me on Ubuntu Server 18.04.1 and MySQL 5.7.23. I spent a bunch of time trying and failing at setting the password and auth plugin manually, finding the password in logs (it’s not there), etc.

The solution is actually super easy:

It’s really important to do this with sudo . If you try without elevation, you’ll be asked for the root password, which you obviously don’t have.

After a lot of try, I could reset the default password with the following commands (Ubuntu and derivatives):

Sometimes, even after typed in the terminal

I got the error that the mysqld don’t exists. So, quit, and type the same commands again.

And the final command

Sometimes doesn’t work. Only after restart the computer.

I just installed Linux Mint 19 (based on Ubuntu 18.04) on my machine. I installed MySQL 5.7 from the repo (sudo apt install mysql-server) and surprisingly during installation, the setup didn’t prompt to enter root password. As a result I wasn’t able to login into MySQL. I googled here and there and tried various answers I found on the net, including the accepted answer above. I uninstalled (purging all dpkgs with mysql in its name) and reinstalled again from the default Linux Mint repositories. NONE works.

After hours of unproductive works, I decided to reinstall MySQL from the official page. I opened MySQL download page (https://dev.mysql.com/downloads/repo/apt) for apt repo and clicked Download button at the bottom right.

Next, run it with dpkg:

At the installation setup, choose the MySQL version that you’d like to install. The default option is 8.0 but I changed it to 5.7. Click OK to quit. After this, you have a new MySQL repo in your Software Sources.

Update your repo:

Finally, install MySQL:

And now I was prompted to provide root password! Hope it helps for others with this same experience.
