Short References for Mysql Passwords related issues:
Mysqladmin command to set password for first time
To setup root password for first time (default is no password), use mysqladmin command at shell prompt as follows:
mysqladmin -u root password NEWPASSWORD
Mysqladmin command to change old password (if you already know the old one)
However, if you want to change (or update) a root password, then you need to use following command
mysqladmin -u root -p'oldpassword' password newpass
For example, If old password is abc, and we will set it to new password 123456, enter:
mysqladmin -u root -p'abc' password '123456'
Change password for existing mysql user (inside mysql)
SET PASSWORD FOR 'radius'@'localhost' = PASSWORD('NEWPASS'); SET PASSWORD FOR 'conntrack'@'localhost' = PASSWORD('NEWPASS');
