When Navicat connects to MySQL, it pops up: 1045: Access denied for user 'root'@'localhost'

Error reason: When the Error 1045 error occurs when logging in to the MySQL database, it means that the user name or password you entered is incorrect and the access is denied. It may also be that your account is not allowed to log in remotely, and you can only log in to the database locally on localhost.

The solution is as follows:

1. Open cmd with administrator privileges, and cd into the bin file of the mysql installation directory.
   
   

2. Start mysql and enter mysql
The first step: start the mysql service, which can be achieved through the "net start mysql" command;

Step 2: Enter on the command line: mysql -u username -p password; press Enter; -h means server name, localhost means local, -hlocalhost can be omitted; -u is database username, root is mysql defaultUser name; -p is the password. If a password is set, you can directly enter it after the -p link, such as: -p123456, the user has not set a password. When Enter password is displayed, just press Enter.)
mysql -u root -p

3.
GRANT ALL PRIVILEGES ON . TO “root”@”%” IDENTIFIED BY 'database password' WITH GRANT OPTION; # Modify authorization to give any host permission to access the database
GRANT ALLPRIVILEGES ON . TO “root”@”%” IDENTIFIED BY '123456' WITH GRANT OPTION
mysql> FLUSH PRIVILEGES; # Refresh permissions, authorized modifications take effect

mysql> exit; # Exit MySQL server

When connecting with Navicat again, enter the password modified above for the password

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
