debian系统mysql远程链接10060/10045

debian系统远程数据库连不上，首先要监听防火墙端口

iptables -I INPUT -p tcp --dport 3306 -j ACCEPT

防火墙生效

iptables-save > /etc/iptables

再本机进入数据库

先改host=>%

mysql -u root -p
use mysql;
update user set host = '%' where user = 'root'  and host='localhost';
flush privileges;

再给远程权限

grant all privileges on *.* to 'root'@'%' identified by 'password' with grant option; 

FLUSH PRIVILEGES;
