Problem: Lost connection to MySQL server at ‘reading initial communication packet’ appears when navacat remotely connects to mysql. Solution

The analysis should be caused by the following two reasons:

服务器有防火墙，禁止3306端口的访问。
用户没有授权远程访问。

MySQL 8.x settings allow remote access

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

#再执行两次

GRANT ALL ON *.* TO 'root'@'%';

# 所有操作后，应执行
flush privileges;

First enter my.cnf on linux. It is usually in /etc/my.cnf. If it does not exist, create it yourself.

Comment out the bind-address line in my.cnf. Whether it is bind-address=127.0.0.1 or bind-address=0.0.0.0, comment out the bind-address line.

Add skip-name-resolve to my.cnf

Restart the mysql service: service mysql stop, service mysql start or just say service mysql restart
