MySQL Safe Mode
Sometime you want to connect to your DB server without password because:

- Many more …
In this article let assume we forgot our userID password and would like to reset it.
Stop MySQL
|
1 |
sudo service mysql stop |
Find mysqld_safe location
To find the mysqld_safe location run the below command.
|
1 |
which mysqld_safe |
Start MySQL in Safe Mode
To start mysql in safe mode run the below command.
|
1 |
sudo [/location_of_mysqld_safe]/mysqld_safe --skip-grant-tables--skip-networking |
–skip-grant-tables: This option causes the server to start without using the privilege system at all, which gives anyone with access to the server unrestricted access to all databases
–skip-networking : This option will block TCP/IP Connection to MySQL except local connection.
This will be an ongoing command until the process is finished so open another shell/terminal window, log in without a password:
|
1 |
mysql -u root -p |
You don’t have to provide a password here, nice isn’t it!!
|
1 |
update mysql.user set authentication_string=password('myPassword') where user='xxx' and host='xxx'; |
(replace xxx with your own userID and password)
|
1 2 3 |
flush privileges; quit; |
Start MySQL server
|
1 |
sudo service mysql start |
Now you should be able to connect to root with your new password :
|
1 |
mysql -u root -p |
Give it a try in your development environment at first. Do not forget trying everything on development first.
