How to query the user's password in mysql under linux
View users
There is no direct SQL statement to view the user, but to enter the user table of the mysql database (this mysql library and user table are both there from the beginning), directly use select * from user; to see what users are there
use mysql;
select * from user;
The user password is encrypted and cannot be read.
If you forget the mysql password, you can reset the password. How to reset the password: Method 1:
Pause the mysql service
[root@localhost ~]# /etc/init.d/mysqld stop
Shutting down MySQL. [OK]
Skip grant table authorization, enter safe mode, and run in the background
[root@localhost ~]# mysqld_safe --skip-grant-tables &
[1] 5261
[root@localhost ~]# 180729 17:38:21 mysqld_safe Logging to '/usr/local/mysql/data/localhost.localdomain.err'.
180729 17:38:21 mysqld_safe Starting mysqld daemon with databases from /usr/local/mysql/data
[root@localhost ~]# jobs
[1]+ Running mysqld_safe --skip-grant-tables &
Enter safe mode to change password
[root@localhost ~]# mysql
