Can't connect to mysql server on *.*.*.*(10038)

ubuntu server16.04.1下安裝了MySQL 5.7數據庫，而後在windows下經過Navicat for MySQL鏈接時，出現 Can't connect to mysql server on xxx.xxx.xxx.xxx(10038) 的問題。

1.查看了Linux版本

sudo lsb_release -a

2.首先查看端口是否打開

netstat -an|grep 3306

3.vim my.cnf

將bind-address = 127.0.0.1修改成bind-address = 0.0.0.0

4.重啓mysql /etc/init.d/mysql restart 等價於 service mysql restart

5.鏈接mysql

mysql -u root -p

show databases;

use mysql;

desc user;查看user表裏的全部字段

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

6.受權

grant all privileges on *.* to root@'%' identified by '123' WITH GRANT OPTION;

7.刷新 flush privileges;

8.防火牆開放端口

服務器的防火牆，須要開啓3306端口
