Navicat connects to Linux MySQL remotely

Open the Linux terminal, enter the root authority, and open the MySQL configuration file with vim

vim /etc/mysql/mysql.conf.d/mysqld.cnf

Change the value of bind-address to 0.0.0.0

 Enter MySQL

mysql -u root -p

Change the root user to allow remote login

update user set host = '%' where user = 'root';

create user

CREATE USER '用户名'@'%' IDENTIFIED BY '密码';

Grant remote access

GRANT ALL PRIVILEGES ON *.* TO '用户名'@'%' WITH GRANT OPTION;

Refresh to take effect

FLUSH PRIVILEGES;

quit

exit

reboot

service mysql restart

Open Navicat, click the new connection of the file, and enter a string of characters

 Connection failed hehe

It turns out that my Navicat version is a bit low, and I need to add a rule for compatibility

mysql command

ALTER USER '用户名'@'%' IDENTIFIED WITH mysql_native_password BY '密码';

If an error is reported that the root user does not have SYSTEM_USER authority, add this command

grant system_user on *.* to 'root';

Refresh, success
