Default mysql password in linux

Where is the default root password for MySQL on Ubuntu?

After a fresh new install of MySQL 5.7 on Ubuntu 19, when I attempt to log in for first time I cannot because I don’t have the credentials. But the install did not prompt for credentials. I tried doing a grep for ‘temporary password’ in the following directories but none have a temp password. Where is the default password located? Thank you.

Restart MySQL in passwordless mode, reset the password, restart the MySQL service.

# 1 : Stop mysql service /etc/init.d/mysql stop # 2: Start to MySQL server w/o password: mysqld_safe --skip-grant-tables & # Step # 3: Connect to mysql server using mysql client: mysql -u root 

-- 4: Setup new MySQL root user password use mysql; update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root'; flush privileges; quit 

# 5: Stop MySQL Server: /etc/init.d/mysql stop # 6: Start MySQL server and test it /etc/init.d/mysql start mysql -u root -p 

After doing step 2, attempting step 3 doesn’t work. I get ‘Can’t connect to local MySQL server through socket’ error.

I also get the following when attempting step 2. ‘ mysqld_safe Directory ‘/var/run/mysqld’ for UNIX socket file don’t exists.’

Can’t connect to local MySQL server through socket Follow these step to resolve this

Find your socket file by running.

create a link to this file in tmp directory.

sudo ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock

Well, none of the above well-intentioned answers worked for me, on Ubuntu 20.04-6. Turns out, mysqld’s default socket file path doesn’t exist when mysqld isn’t running, and mysqld_safe doesn’t create it. So the answer is to create the socket directory, and also set ownership to Unix user mysql-

$ sudo systemctl stop mysql.service $ sudo mkdir /var/run/mysqld $ sudo chown mysql.mysql /var/run/mysqld $ sudo mysqld_safe --skip-grant-tables --socket=/var/run/mysqld/mysqld.sock & $ mysql -u root > *proceed with mysql password change* > ^D $ mysqladmin shutdown $ sudo systemctl start mysql.service 

This worked for me. Now you should be able to go about your mysql business as usual, as I was.

UPDATE- if you’ve just installed MySQL 8.0+, there’s now a straightforward way to set the root password: Securing the Initial MySQL Account

When it comes to MySQL database creation and management on Linux, one of the most common questions is about the default password. Many users are often unsure of what the default MySQL database password is in Linux. In this blog post, we will explore the important points, key points, and helpful points related to the default MySQL database password in Linux.

MySQL Authentication Plugin

By default, MySQL has the root user’s authentication plugin as auth_socket which requires the system username and db user. This means that you can only log in to the MySQL database as the root user if you are logged in to the Linux system as the root user. This is a security feature that ensures that only authorized users can access the database.

In MySQL, by default, the username is root, and there’s no password. This means that if you are logged in to the Linux system as the root user, you can log in to the MySQL database as the root user without a password. However, this is not recommended for security reasons.

Validate_password is installed to implement password checking. This plugin is used to ensure that the passwords for all users meet certain complexity requirements. By default, this plugin is enabled and requires passwords to be at least eight characters long, contain at least one uppercase letter, one lowercase letter, one digit, and one special character.

Default MySQL Password

There is no default password (empty password) for MySQL database. To assign a password to the initial root account created during the MySQL installation procedure, use the command “mysql -u root -p” and enter the password. This will prompt you for a password, which you can then enter to set the password for the root user.

The MySQL PASSWORD function is used for the generation of a hashed password using a plain-text password string. This function is used to store passwords in a secure way in the MySQL database.

Resetting the MySQL Root Password

If you forget the root password for your MySQL database, you can reset it by following these steps:

1. Stop the MySQL server: sudo systemctl stop mysql
2. Start the MySQL server in safe mode: sudo mysqld_safe —skip-grant-tables &
3. Log in to the MySQL server as the root user: mysql -u root
4. Set a new password for the root user: ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘new_password’;
5. Exit MySQL: exit
6. Restart the MySQL server: sudo systemctl start mysql

MySQL Installation and Password Validation

MySQL installation involves initializing the data directory, including the grant tables in the MySQL system database that define MySQL accounts. During the installation process, you will be prompted to set a password for the root user.

There are three levels of password checking: LOW, MEDIUM, and STRONG, with the default being MEDIUM. The level of password checking can be set using the validate_password_policy variable in the MySQL configuration file.

MySQL 8.0 has improved password validation capabilities. It now includes a password strength meter that rates passwords on a scale of 0 to 100 based on their complexity.

Additional Helpful Points

MySQL Workbench is a popular tool for MySQL database development and management. It provides a graphical user interface for managing MySQL databases and includes features such as database modeling, SQL development, and database administration.

MySQL supports multiple storage engines, including InnoDB, MyISAM, and MEMORY. Each storage engine has its own advantages and disadvantages, so it is important to choose the right one for your specific use case.

MySQL can be used with various programming languages, including PHP, Python, and Java. It provides APIs for these languages that allow you to connect to the MySQL database and perform operations such as inserting, updating, and deleting data.

MySQL can be used for various applications, including web development, data warehousing, and e-commerce. It is a reliable, scalable, and fast database management system that is used by many popular websites and applications, including Facebook, Twitter, and WordPress.

best practices for mysql security include using strong passwords, limiting access, and keeping the server software up-to-date. It is also recommended to use SSL/TLS encryption to secure communications between the client and the server.

MySQL Default Password – How To Find And Reset It

When installing MySQL, you may noticed that it does not ask for a password. This become troublesome when you want to connect your application to MySQL database. In this article, I will show you on how to find MySQL default password.

MySQL Default Password

Well, straight forward, by default the username is root and there is no password setup. You may need to reset the root password.

Also, in case you have accidently put a password during installation process and can’t recall the password, you need to reset the password.

There is no way to view the password as it’s already written as hashed.

How To Reset MySQL Default Password

Windows OS

1. Ensure that your logged on account has administrator rights.

2. On the windows search box, search for services.msc and click to open.

3. Scroll down to all services with its status. Find MySQL services, right-click on it and click stop services.

4. Create a text file which contains the SQL statement in a single line as below:

ALTER USER ‘root’@’localhost’ IDENTIFIED BY ‘MyNewPass’;

Change MyNewPass to your new desired password.

5. Save it to a text file. For example, save it as C:\new-password.txt.

6. On the windows search box, search for cmd and click Run as administrator.

7. Start the MySQL with init_file system variable set to text file name created as below:

C:\> cd “C:\Program Files\MySQL\MySQL Server 5.7\bin” C:\> mysqld –init-file=C:\\mysql-init.txt

You may replace your MySQL installation location after cd command.

Linux

1. Open terminal.

sudo /usr/local/mysql/support-files/mysql.server stop

3. Start MySQL in safe mode.

sudo mysqld_safe –skip-grant-tables

4. Open another terminal and login as root by run below command.

3. Once MySQL is logged in via terminal, run below queries.

UPDATE mysql.user SET authentication_string=PASSWORD(‘password’) WHERE User=’root’; FLUSH PRIVILEGES;

mysql>UPDATE mysql.user SET authentication_string=PASSWORD(‘password’) WHERE User=’root’; FLUSH PRIVILEGES;

(Note: In MySQL 5.7, the password field in mysql.user table field was removed, now the field name is ‘authentication_string’.)

If you are using MySQL 5.7 and above you need to run command as below:

mysql> use mysql; mysql>update user set authentication_string=password(‘password’) where user=’root’; FLUSH PRIVILEGES;

4. Now, you can exit MySQL safe mode.

If you received error ‘access denied’ you can run below command with the new password:

mysqladmin -u root -p shutdown

5. Start MySQL service again by run below command.

What If Still Failed To Reset MySQL Default Password?

If by using ALTER USER still not able to reset password, you may try to modify the user table directly by repeating the steps above and run below query:

UPDATE mysql.user SET authentication_string = PASSWORD(‘MyNewPass’), password_expired = ‘N’ WHERE User = ‘root’ AND Host = ‘localhost’; FLUSH PRIVILEGES;

Thanks for reading this article. I hope you find it helpful.
