What does % stand for in host column and how to change user's password?
The localhost means you can access from same machine while from % the remote host access is possible. The syntax is as follows to change the user password.
SET PASSWORD FOR 'yourUserName'@'localhost' ='yourPassword';
First check the user and host from MySQL.user table. The query is as follows −
mysql> select user,host from MySQL.user;
Here is the output −
+------------------+-----------+ | user | host | +------------------+-----------+ | Bob | % | | Manish | % | | User2 | % | | mysql.infoschema | % | | mysql.session | % | | mysql.sys | % | | root | % | | @UserName@ | localhost | | Adam Smith | localhost | | James | localhost | | John | localhost | | John Doe | localhost | | User1 | localhost | | am | localhost | | mysql.infoschema | localhost | | mysql.session | localhost | +------------------+-----------+ 16 rows in set (0.01 sec)
Now, let us change the password for user ‘John’. The query is as follows −
mysql> SET PASSWORD FOR 'John'@'localhost' ='John123456'; Query OK, 0 rows affected (0.35 sec)
After that you need to set the flush privileges. The query is as follows −
flush privileges;
