MySQL user DB does not have password columns - Installing MySQL on OSX

Question

I am trying to change MySql root password   What I have done is below    Install MySql-5 7 6    dmg Community Server  and workbench  Turn off the server on OSX System preferences  Access MySql with console  The command was mysqld safe --skip-grant Execute update user set password password  1111   where user  root   and got an error message --  ERROR 1054  42S22   Unknown column  password  in  field list     FYI  I did use mysql   So I did select query on user table and found password column actually does not exist    It is very weird  Is it possible that original user table does not have password column   How can I change password  which does not exist   Thanks for your answer  D

Use the ALTER USER command rather than trying to update a USER row  Keep in mind that there may be more than one  root  user  because user entities are qualified also by the machine from which they connect  https   dev mysql com doc refman 5 7 en alter-user html  For example   ALTER USER  root   localhost  IDENTIFIED BY  new-password   ALTER USER  root      IDENTIFIED BY  new-password

Root Cause  root has no password  and your python connect statement should reflect that    To solve error 1698  change your python connect password to      note  manually updating the user s password will not solve the problem  you will       still get error 1698

This error happens if you did not set the password on install  in this case the mysql using unix-socket plugin    But if delete the plugin link from settings  table mysql user  will other problem  This does not fix the problem and creates another problem  To fix the deleted link and set password   PWD   do   1  Run with --skip-grant-tables as said above    If it doesnt works then add the string skip-grant-tables in section  mysqld  of   etc mysql mysql conf d mysqld cnf  Then do  sudo service mysql restart   2  Run mysql -u root -p  then  change  PWD     update mysql user      set authentication string PASSWORD  PWD    plugin  mysql native password       where User  root  and Host  localhost       flush privileges   quit   then sudo service mysql restart  Check  mysql -u root -p   Before restart remove that string from file mysqld cnf  if you set it  there

One pitfall I fell into is there is no password field now  it has been renamed so   update user set password PASSWORD  YOURPASSWORDHERE   where user  root    Should now be   update user set authentication string password  YOURPASSWORDHERE   where user  root

User · Answer

For this problem  I used a simple and rude method  rename the field name to password  the reason for this is that I use the mac navicat premium software in the visual operation error  Unknown column  password  in  field List    the software itself uses password so that I can not easily operate  Therefore  I root into the database command line  run  Use mysql    And then modify the field name   ALTER TABLE user CHANGE authentication string password text    After all normal
