端口3306没有侦听吗?无法远程连接到MySQL

我正在尝试使用pymysql远程连接到MySQL,但收到错误消息:

(2003, "Can't connect to MySQL server on 'ip address' ([WinError 10061] 
No connection could be made because the target machine actively refused it)")

在我的my.cnf文件中,绑定地址设置为0.0.0.0,而跳过网络不在那里。运行"sudo netstat -atn“显示端口3306仅在本地主机上侦听:

Proto Recv-Q Send-Q Local Address           Foreign Address         State
tcp        0      0 0.0.0.0:22              0.0.0.0:*               LISTEN
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN

我的防火墙允许来自3306的流量:

To                         Action      From

3306/tcp (v6)              ALLOW       Anywhere (v6)
3306/udp (v6)              ALLOW       Anywhere (v6)

我已经重启了很多次了。我不认为这是一个MySQL身份验证问题。我已经将我的用户主机设置为'%‘。如何将服务器设置为侦听3306上的任何地址,而不仅仅是127.0.0.1?

编辑:这是'ps auxf | grep mysqld‘的输出:
