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

Save settings
/etc/init.d/iptables save

start no longer start firewall service
chkconfig iptables off

3. Reconnect

Let’s talk about this error first. In fact, our MySQL does not allow remote login, so the remote login failed. The solution is as follows:

1. Log in to MySQL on the machine where MySQL is installed mysql -u root -p password
2. implementuse mysql;
3. After executing update user set host = '%' where user = 'root';this sentence, an error may be reported, ignore it.

4. implementFLUSH PRIVILEGES;

   After the above 4 steps, you can solve this problem.
   Note: The fourth step is to refresh the MySQL permission-related table. Don't forget, I didn't perform the fourth step the first time, and the result was always unsuccessful, and finally I found the reason.

4. Reconnect

Remote connection succeeded!

Please master a lot of exhibitions!
