Error 1045 (28000) occurs when Linux logs in MySQL: access denied for user 'root' @ 'localhost' (using password: yes)

We need to bypass the password to login

Add such a jargon

# Add do not add .service Suffixes are OK  

 start-up ：systemctl start mysqld.service 

 close ：systemctl stop mysqld.service
