First check the brew status:
brew doctor confirms that brew is working properly
brew update update version
brew install mysql install mysql
After executing the above three commands, if a git-related error occurs when installing mysql, execute the prompt command cv in the error and then execute brew install mysql again.
After successful installation, you do not need a password by default to enter mysql -uroot to log in to mysql.
Because the user password authentication strategy of mysql8 has changed from mysql_native_password to caching_sha2_password, the mysql module of nodejs reports an error when starting. Mysql does not support the latest authentication strategy of mysql8.
Modify mysq8 authentication policy:
alter user 'root'@'%' identified with mysql_native_password by 'your password';
% means that any IP host can use root to log in. Your password is the password you modified with the following command:
ALTER USER 'root'@'localhost' IDENTIFIED BY 'New password to be changed';
After successfully modifying the policy, use the following command to view it:
select user,plugin from user where user='root' ;
At this point the password policy has been modified successfully
Set to allow any remote host connection (the default is to only allow the current localhost connection)
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'your password' WITH GRANT OPTION;
Then start the node service and connect to mysql and it will be OK:
