No connection could be made because the target machine actively refused it (PHP / WAMP)

January 21, 2022, at 08:10 AM

Note: I realise this could be seen as a duplicate but i have looked at the other responses and they didn't fix the problem for me.

I have recently installed Zend Studio and Zend Server with the mysql plugin on Windows 7.

I am not a qualified server administrator but neither am i completely incompetent; i have dedicated my day trying to get a local development 'server' up to cut down on upload/download times.

When I say server/machine i mean my home computer

I have come to a grinding halt trying to get mysql to work with Zend Server.

The error I keep receiving is (or verbose):

#2002 Cannot log in to the MySQL server
or (if i change to 'config' authentication type)
#2002 - No connection could be made because the target machine actively refused it.
The server is not responding (or the local server's socket is not correctly configured).

I have tried:

  • Change $cfg['Servers'][$i]['host'] from 'localhost' to ''
  • Add/Remove $cfg['Servers'][$i]['socket'] = '';
  • Change from cookie to config auth type
  • reinstall server and mysql
  • Disable firewalls
  • Restarting machine

Zend's approach was to 'configure the phpmyadmin setup screen'... done that i don't know how many times.

Can anyone on here lend a hand, or point me in a direction that I haven't tried yet?

Answer 1
  1. Go to C:\wamp\bin\mysql\mysql[your-version]\data
  2. Copy and save "ib_logfile0" and "ib_logfile1" anywhere else.
  3. delete "ib_logfile0" and ib_logfile1

Did the trick for me. hope it works for you too.

Its working fine. But we will have to stop apache and mysql, We need to quit xampp and then delete file. when deleted successfully. now start xampp it will work properly..

Answer 2

Just Go to your Control-panel and start Apache & MySQL Services.

Answer 3

You might need:

  • In wamp\bin\mysql\mysqlX.X.XX\my.ini find these lines:

    [client] ... port = 3308 ... [wampmysqld64] ... port = 3308

As you see, the port number is 3308 (or maybe 3306). You should :

  • use that port in applications, like WordPress: define('DB_HOST', 'localhost:3308')


  • change it globally in wamp\bin\apache\apache2.X.XXX\bin\php.ini change mysqli.default_port = ... to 3308
Answer 4

Till yesterday I was able to connect to phpMyAdmin, but today I started getting this error:


None of the answers here really helped me fix the problem, what helped me is shared below:

I looked at the mysql logs.[C:\wamp\logs\mysql.log]

It said

I got the clue that this guy is creating a problem - InnoDB: Error: could not open single-table tablespace file .\testdb\testtable.ibd

and this line 2015-09-18 01:16:30 5920 [Note] InnoDB: Database was not shutdown normally!

hmmm, For me the testdb was just a test-db! hence I decided to delete this file inside C:\wamp\bin\mysql\mysql5.6.17\data\testdb

and restarted all services, and went to phpMyAdmin, and this time no issues, phpMyAdmin opened :)

Answer 5

I'm having the same problem with Wampserver. It’s worked for me:

You must change this file: "C:\wamp\bin\mysql[mysql_version]\my.ini" For example: "C:\wamp\bin\mysql[mysql5.6.12]\my.ini"

And change default port 3306 to 80. (Lines 20 & 27, in both)

port = 3306 To port = 80

I hope this is helpful.

Answer 6

All I have to do in order to get rid of that error was to restart my wamp server.

  1. I clicked on the wamp icon.
  2. i went to MySQL > Service administration 'wampmysqld64' > install service
