Navicat 远程连接 mysql 报10038的错误

1、首先开放mysql远程访问权限

mysql> USE mysql; 

Database changed

//赋予任何主机访问数据的权限 

mysql>GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'WITH GRANT OPTION 


//允许用户 eaphy 使用密码 123456 从任何主机连接到mysql服务器的话。 

mysql>GRANT ALL PRIVILEGES ON *.* TO 'eaphy'@'%'IDENTIFIED BY '123456' WITH GRANT OPTION; 

//允许用户 eaphy 从ip为192.168.0.8的主机连接到mysql服务器，并使用 123456 作为密码 

mysql>GRANT ALL PRIVILEGES ON *.* TO 'eaphy'@'192.168.0.8'IDENTIFIED BY  '123456' WITH GRANT OPTION; 

//修改生效 
mysql>FLUSH PRIVILEGES 

mysql>EXIT 

2、开放 3306 端口

// centos 7

[eaphy@localhost /]$ firewall-cmd --zone=public --add-port=3306/tcp --permanent
success
[eaphy@localhost /]$ firewall-cmd --reload
success
