I had to go this route on Ubuntu 16 04 1 LTS   It is somewhat of a mix of some of the other answers above - but none of them helped  I spent an hour or more trying all other suggestions from MySql website to everything on SO  I finally got it working with   Note  while it showed Enter password for user root  I didnt have the original password so I just entered the same password to be used as the new password   Note  there was no  var log mysqld log only  var log mysql error log  Also note this did not work for me   sudo dpkg-reconfigure mysql-server-5 7  Nor did   sudo dpkg-reconfigure --force mysql-server-5 5  Make MySQL service directory   sudo mkdir  var run mysqld  Give MySQL user permission to write to the service directory   sudo chown mysql   var run mysqld  Then    kill the current mysqld pid run mysqld with sudo  usr sbin mysqld  amp  run  usr bin mysql secure installation  Output from mysql secure installation     root myServer     usr bin mysql secure installation      Securing the MySQL server deployment       Enter password for user root       VALIDATE PASSWORD PLUGIN can be used to test passwords   and improve security  It checks the strength of password   and allows the users to set only those passwords which are   secure enough  Would you like to setup VALIDATE PASSWORD plugin       Press y Y for Yes  any other key for No  no   Using existing password for root    Change the password for root     Press y Y for Yes  any other key for No    y      New password       Re-enter new password    By default  a MySQL installation has an anonymous user    allowing anyone to log into MySQL without having to have   a user account created for them  This is intended only for   testing  and to make the installation go a bit smoother    You should remove them before moving into a production   environment       Remove anonymous users   Press y Y for Yes  any other key for No    y   Success       Normally  root should only be allowed to connect from    localhost   This ensures that someone cannot guess at   the root password from the network       Disallow root login remotely   Press y Y for Yes  any other key for No    y   Success       By default  MySQL comes with a database named  test  that   anyone can access  This is also intended only for testing    and should be removed before moving into a production   environment       Remove test database and access to it   Press y Y for Yes  any other key for No    y         Dropping test database      Success    Removing privileges on test database      Success          Reloading the privilege tables will ensure that all changes   made so far will take effect immediately       Reload privilege tables now   Press y Y for Yes  any other key for No    y   Success       All done

As mysql documentation on the password   function says       This function was removed in MySQL 8 0 11    This invalidates pretty much all existing answers for mysql v8 0 11 and newer   Per mysql documentation the new generic way to reset the root password is as follows      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   mysql client  but this approach is less secure        Stop the MySQL server if necessary  then restart it with the   --skip-grant-tables option  This enables anyone to connect without a password and with all privileges  and disables account-management   statements such as ALTER USER and SET PASSWORD  Because this is   insecure  if the server is started with the --skip-grant-tables   option  it enables --skip-networking automatically to prevent remote   connections       Connect to the MySQL server using the mysql client  no password is   necessary because the server was started with --skip-grant-tables   shell gt  mysql       In the mysql client  tell the server to reload the grant tables so that account-management statements work   mysql gt  FLUSH PRIVILEGES        Then change the  root   localhost  account password  Replace the password with the password that you want to use    To change the password for a root account with a different host name   part  modify the instructions to use that host name   mysql gt  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 and --skip-networking options

I haven t seen the official steps recommended by the MySQL 8 0 guide  which were the only ones that worked for me  Here s a summary of those steps    Stop the MySQL server if it is running  Look in  var lib mysql    var run mysqld   or  usr local mysql data  to find the pid file with the server s process ID  Generally the file begins with either mysqld or your system s host name and ends with  pid  Replace mysql-data-directory and host name that you just found  in the following command      sudo kill  sudo cat  mysql-data-directory host name pid   This command will create a text file in  tmp mysql-init with the SQL statement and makes the mysql user the owner  Replace in the command MyNewPass with your own password      echo  ALTER USER  root   localhost  IDENTIFIED BY  MyNewPass     gt   tmp mysql-init  amp  amp  sudo chown mysql  tmp mysql-init  Start the MySQL server by running the following command on the command line  After this the password is updated and you can close the server again with CTRL C     sudo mysqld --user mysql --init-file  tmp mysql-init  amp   Remove the temporary file with your password     sudo rm  tmp mysql-init

Instead of resetting the password there is a work around on the local machine if you have setup phpmyadmin to connect without giving the password or username  Check this out by starting mysql  apache etc  I have xampp installed in my local machine  So starting the xampp will start all the necessary services  Now going to http   localhost phpmyadmin shows me all the databases  This confirms that you have saved the username and passsword in the config file of phpmyadmin which can be found in the phpmyadmin install location  If you have xampp installed the phpmyadmin folder can be found in the root folder of xampp installation  Search for the word password in the config inc php file  There you will find the password  and username

When you use MySQL s PASSWORD   on the system where you want to change the password  it  can cause the password turn up in a MySQL log in cleartext  source   Keeping them  their backups etc  as secure as the password sounds like nightmare to me  so I rather like to do it as follows    On your local machine  run this with your password    mysql -u someuser -p  lt   lt  echo  SELECT PASSWORD  mypass        Note the space in front to prevent it from turning up in the bash history  for other distros than Ubuntu  this might work differently     source   On your server machine  execute the following command to change its MySQL root password  replace myhash with your password s hash as printed by the first command    mysql -u root -p  lt   lt  echo  SET PASSWORD FOR root localhost    myhash      Optionally  let s be a bit paranoid  On your local machine  clear your terminal screen with clear and purge your virtual terminal scrollback  to hide the cleartext password appearing in the command above
