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  sudo mysql --user root mysql   2  Create a user for phpMyAdmin  CREATE USER  phpmyadmin   localhost  IDENTIFIED BY  some pass   GRANT ALL PRIVILEGES ON     TO  phpmyadmin   localhost  WITH GRANT OPTION  FLUSH PRIVILEGES    Reference - https   askubuntu com questions 763336 cannot-enter-phpmyadmin-as-root-mysql-5-7

I to was experiencing the same problem and the only thing I was able to do to make it work was to go this route       drop user admin localhost  flush privileges  create user admin localhost identified by  admins password    This allowed me to recreate my username and enter a password for the user name

In my case the data directory was automatically initialized with the --initialize-insecure option  So  var log mysql error log does not contain a temporary password but        Warning  root localhost is created with an empty password   Please   consider switching off the --initialize-insecure option    What worked was   shell gt  mysql -u root --skip-password mysql gt  ALTER USER  root   localhost  IDENTIFIED BY  new password     Details  MySQL 5 7 Reference Manual   2 10 4 Securing the Initial MySQL Account

In case you want to install mysql or percona unattended  like in my case ansible   you can use following script     first part opens mysql log   second part greps lines with temporary password   third part picks last line  most recent one    last part removes all the line except the password   the result goes into password variable  password   cat  var log mysqld log   grep  A temporary password is generated for    tail -1   sed -n  s   root localhost    p      setting new password  you can use  1 and run this script as a file and pass the argument through the script  newPassword  wh teverYouLikE     resetting temporary password  mysql -uroot -p password -Bse  ALTER USER  root   localhost  IDENTIFIED BY   newPassword

It seems things were designed to avoid developers to se the root user  a better solution would be   sudo mysql -u root   Then create a normal user  set a password  then use that user to work   create user  user   localhost  identified by  user1234   grant all on your database   to  user   localhost   select host  user from mysql user    Then try to access   mysql -u user -p   Boom

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   sudo mysql secure installation   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

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   sudo mysql --user root   But how to then change the root password   To illustrate what s going on   I created a new user  me   with full privileges  with   mysql gt  CREATE USER  me   localhost  IDENTIFIED BY  my new password   mysql gt  GRANT ALL PRIVILEGES ON     TO  me   localhost  WITH GRANT OPTION  mysql gt  FLUSH PRIVILEGES    Comparing  me  with  root    mysql gt  SELECT user  plugin  HEX authentication string   FROM mysql user WHERE user    me  or user    root    ------ ----------------------- ----------------------------------------------------------------------------    user   plugin                  HEX authentication string                                                     ------ ----------------------- ----------------------------------------------------------------------------    root   auth socket                                                                                            me     mysql native password   2A393846353030304545453239394634323734333139354241344642413245373537313       ------ ----------------------- ----------------------------------------------------------------------------    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   ALTER USER  root   localhost  IDENTIFIED WITH mysql native password BY  SOME NEW ROOT PASSWORD     A good explanation   More details from the MySQL manual

As of Ubuntu 20 04 with MySql 8 0   you can set the password that way   login to mysql with sudo mysql -u root  change the password     USE mysql  UPDATE user set authentication string NULL where User  root   FLUSH privileges  ALTER USER  root   localhost  IDENTIFIED WITH caching sha2 password BY  My-N7w And 5ecure-P s5w0rd   FLUSH privileges  QUIT   now you should be able to login with mysql -u root -p  or to phpMyAdmin with username root  and your chosen password  P S  You can also login with user debian-sys-maint  the password is written in the file  etc mysql debian cnf

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 mysql secure installation    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

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     grep  temporary password   var log mysqld log Run mysql secure installation to change new password   ref  http   dev mysql com doc refman 5 7 en linux-installation-yum-repo html

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   sudo dpkg -i mysql-apt-config 0 8 10-1 all deb   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   sudo apt update   Finally  install MySQL   sudo apt install mysql-server   And now I was prompted to provide root password  Hope it helps for others with this same experience
