After XAMPP is installed in Linux, Navicat cannot connect to the database.

After XAMPP is installed in Linux, Navicat cannot connect to the database. After XAMPP is installed in Linux, mysql is installed in its own environment. At this time, the root user of mysql does not have a password. Www.2cto.com first enters mysql and enters the command: mysql-uroot-p. Enter the password and press Enter. Set password = password ('20140901'); after the password is set, use the local Navicat to connect to the mysql instance and find that the mysql instance cannot be connected, the pop-up box shows that the root user under another ip address is denied access! Www.2cto.com was originally because root was not granted sufficient permissions! Run this command: grant all privileges on *. * TO 'root' @ '%' identified by 'mypassword' with grant option; after the command is executed, do not forget TO restart mysql. At this time, the Navicat client can easily connect to the mysql database.
