MySQL Remote connection problem Lost connection to MySQL server at ' reading initial communication packet ', System error:0

When I connect MySQL remotely with navicat for MySQL, there is a

Lost connection to MySQL server at ' reading initial communication packet ', System error:0

It's disgusting, the server restarted once, and all the morning it was dealing with MySQL problems.

Both methods do not take effect:

Modify the My.cnf file (Windows is My.ini)

General in the MySQL installation directory,/etc/mycnf.

In the MY.CNF configuration file in the [mysqld] area add skip-name-resolve, to see the Netizen is to skip the MySQL connection DNS reverse resolution function, so as to improve the performance of MySQL. In this case, you can only use the IP in the MySQL authorization table to connect to the MySQL service.

But it does not take effect. Attach several parameters to the MY.CNF configuration:
Skip-name-resolve skips the DNS reverse parsing process. (so you can't use hostname to connect to MySQL, only use IP connection)
Skip-grant-tables Skip Authorization Form (solution when MySQL login password is forgotten)
Skip-networking skipping TCP/IP connections
Skip-host-cache disable host name caching; To clear the hostname cache, execute the FLUSH hosts statement or execute the mysqladmin flush-hosts command

Put the client's IP in the MySQL server's/etc/hosts file, give a name to do the host mapping.

Because the working environment needs to access MySQL at multiple addresses, it is not realistic to maintain the hosts file, so it is eliminated ...

Finally found ...
Remote access to MySQL can be, is not local access, that is, you can run in the production environment as usual. That's disgusting.
