MySQL error: Can't get hostname from your ip address

Question

I use my remote MySQL database during long time.

But today I suddenly have found that I cannot connect to the database. I have got an error.

"Can't get hostname from your ip address".

I haven't changed anything in MySQL settings.

What's the problem?

Answer 1

Just add below in my.ini or my.cnf.

[mysqld]

skip-name-resolve 

Linux:

Otherwise, start MySQL server with the following flag:

sudo service --skip-name-resolve

Answer 2

I've got the same error message on windows. I found my problem is the local server host file. Check the localhost or any hostname you use in the file c:\windows\system32\drivers\etc\host

My original host file: 127.0.0.1 localhost ::1 localhost

I just delete the second line and use the first line only: 127.0.0.1 localhost

Then, problem solved, for my problem. Hope it helps.

Answer 3

I ran into this problem when installing MySQL 8 on a Windows 10 machine. Most of the solutions found on the internet are setting skip-name-resolve which never worked for me. At last I found out this one which worked for me:

netsh winsock reset

Then reboot the computer. Also try set

127.0.0.1 localhost

in %windir%\System32\drivers\etc\hosts if needed.

Answer 4

I know this question was asked quite some time ago and most people have figured it out by now, but for those who haven't, here was my solution:

Add the port number with the server name in you connection string

connectionstring = "server=server;Port=3306;User Id=UserNAme;password=password;Persist Security Info=True;database=DatabaseName;convert zero datetime=true";
