Navicat MySQL 8.017 connectivity problems that occur

Since the installation of the latest version of the official website, there have been some minor problems in the database connection process

　　Download free installation version of "Windows (x86, 64-bit), ZIP Archive", direct decompression, can refer to the following article:

• Mysql8.0.11 download and install

　　Generate random passwords root, tedious and bad memories, so it is necessary to modify the initial password

　　To use the Alter User Change Password

The USER the ALTER ' root ' @ ' localhost ' IDENTIFIED BY ' new password ' ;

　　Here there is a problem, use navicat connection fails:

Authentication plugin 'caching_sha2_password' cannot be loaded

　　Before MySQL 8.04, execute: SET PASSWORD = PASSWORD ( '[New Password]'); however MySQL8.0.4 started, so that the default is not acceptable. Because before, MySQL password authentication plug-in is "mysql_native_password", but now using the "caching_sha2_password"

　　So once again we need to modify the password:

　　Start MySQL service: enter the MySQL bin directory

net start mysql

　　Log in MySQL

mysql -u root -p
Enter password：

　　change Password

use mysql；
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '新密码';
FLUSH PRIVILEGES;

　　Navicat can connect successfully
