sorry for this post that it might be repeated, but I could not quite figure out from the other posts still.
I am unable to log on mysql localhost database, and the server is down says mysql#localhost:3366 - Refusing Connections. In mysql workbench start/shutdown mysql server, it is saying the database server instance is unknown (with start server button grayed out) and refreshing the status doesn't help.
Also, the mysql server should always be running automatically in the background whenever PC is restarted, but it is not showing in the services now.
when I try to execute mysqld from cmd, it just shuts down the server. And responds with
-"The Innodb memory heap is disabled"
-"the system tablespace must be writeable"
-"InnoDB init function returned error"
-"InnoDB registration as a storage engine failed"
Anybody has a solution to this? Thanks much!
Install it. Re-install it, if you're convinced it was already installed. The fact that it isn't even listed in the services suggests otherwise however. If it was installed but wouldn't start it would still show up, but not as started.

I am using MySQL workbench to connect to my local server. Everything was running fine and suddenly I jumped in a connection refused errors. I tried restarting the server again and again. Clearing temp files and also restarted my machine. I found this post from which I tried a couple of things like net stop and stopping the process from the services list but in the services list it shows as below:
I waited like for 30 mins but still, the service is not stopped.
Also, below is the screenshot for MySQL workbench when I try to start the server:
Is there anything specific which I need to do in order to resolve this error:
So, I resolved my own problem in this way. I referred the documentation for this particular error and for my error which is of 2003 type it said that look for mysqld.exe process in task manager and if you don't find any then start the server. But, in my case I found 2 mysqld.exe processes running. So, I killed those processes and restarted the server. It worked!!
Might help someone someday :)
I have set up a micro instance server on amazon EC2.
mysql server fails frequently and due to which I get 'error establishing a database connection' whenever I access my website. To make my website work again, I have to restart mysqld. Here is the error log. Please click the link as i just opened the account on stackoverflow.
I read through other threads here for the same kind of error and accordingly I added a swapfile of 3G but I am still getting the same memory allocation error. Here is my swapfile.
I am not a technical person so please help me figure out how to solve this problem.
I have no knowledge of programming or anything beyond basic computer skills, so I'm probably jumping the gun on this.
Anyway, I am trying to understand SQL, so I downloaded MySQL Workbench, Utilities, and MySQL Server.
When I try to make a connection (on the start page of MySQL Workbench) I get an error code that reads:
"Failed to Connect to MySQL at 127.0.0.1:3306 with user root. Can't connect to MySQL server on '127.0.0.1' (61)"
I left the default settings (hostname: 127.0.0.1, port: 3306, user: root, no password) but I still get this error message.
What should I do? I already downloaded MySQL Server but I don't even know how to make sure it is running.
I am using a MacBook Air with OS X Yosemite (v. 10.10.2)
Thank you, I appreciate any help!
It very much sounds like your server is not running. If you use a current version of MySQL Workbench you should however still be allowed to "open" a connection, even if the server is not running. MySQL Workbench has an admin section where you can control your server, including starting it up or shutting it down.
When you open a connection with an unavailable server you see something like this:
Switch to the Startup/Shutdown section and click the "Start Server" button:
If all goes well you see a number of startup messages in the log window and status label changes to "running" (and becomes green). Additionally, the Session window in the lower left corner should now show you some details about your server.
You can now close the admin tab and start running queries in an sql tab.
I got problem (#2006 Mysql server gone away) with mysql while connecting and performing some operations through web browser.
Operation Listed below:
When Executing big procedure
Importing database dump
When Access some particular tables It immediately throws "Server gone away".
Refer this question for Scenarios: Record Not Inserted - #2006 Mysql server gone away
Note : The above operations are works fine when I perform through terminal.
I tried some configuration as googing stated. That is set wait_timeout, max_allowed_packet. I checked for the bin_log but it is not available.
But the issues will not rectified.
What is the problem & How can I figure out & fix the issue?
what is the different between access phpmyadmin mysql server from web browser and terminal?
Where I can find the mysql server log file?
Note: If you know about any one of the above questions. Please post here. It would be helpful to trace.
Please help me to figure this out..
Thanks in advance...
Basically nothing except phpMyAdmin is limited by PHP's timeout and resource limits (limits to keep a runaway script from bogging down your entire machine for all eternity; see the docs for details of those values. In some cases, you might be authenticating through a different user account (for instance, root#localhost and root#127.0.0.1 aren't the same user), but as long as you're using a user with the same permissions the differences are minimal.
You can read more about logs in the MySQL manual, note that "By default, no logs are enabled (except the error log on Windows)".
Below are answer for question
From my research the problem is that browser have some limit to disconnect the connection i.e timeout connection. So that the above problem raised.
To resolve this problem
Go to /opt/lampp/phpmyadmin and open config.inc.php
add the command $cfg['ExecTimeLimit'] = 0;
Restart the xamp server. Now you can perform any operations.
`
2. Web client is differ from terminal because Terminal client will not getting timeout. Terminal client maintain the connection till the progress completed. I recommenced to use command prompt to import/export/run process by safe way.
Basically phpmyadmin will not have any log file. If you wanna see warnings and error you should configure the log file.
Configuration steps:
Go to /opt/lampp/etc/my.cnf
Add log_bin = /opt/lampp/var/mysql/filename.log
Restart the xamp server. You can get the log information.
I'm running into a little trouble with MySQL Workbench.
This is the situation, I'm developing a database to query it remotely from Android devices. This is the first time I use MySQL Workbench, so I've followed this tutorial:
http://net.tutsplus.com/tutorials/databases/visual-database-creation-with-mysql-workbench/
I have no problem creating the EER diagram and generating the SQL script. The problem comes when I try to connect to a MySQL server. I get this error:
"Failed to Connect to MySQL at 127.0.0.1:3306 with user root. Lost connection to MySQL server at 'reading initial communication packet', system error: 61"
http://img101.imageshack.us/i/capturadepantalla201104i.png/ (if the link stops working tell me)
I've also tried using the Local Socket/Pipe connection method with the MAMP Socket in '/Applications/MAMP/tmp/mysql/mysql.sock', but it gives the same error. And I've also tried using MAMP port 8889 but still nothing.
So anyone knows how to fix it? And another question, can I connect from my Android device to my laptop(where the database is placed) without using MAMP? MySQL needs MAMP to serve queries? And the last thing, am I going into the right way? Or should I do it other way?
Thanks for reading.
I had the same issue, but part of your question is what fixed it for me:
Set connection = Local Socket/Pipe
Set socket path = "/Applications/MAMP/tmp/mysql/mysql.sock" (for me - I got the path from my MySQL log upon initialisation)
Running: MBP, OSX 10.8.3 (Mountain Lion), MAMP Pro
Can't really fathom any further what your issue may be, but perhaps double check your DB is properly initialised. But, perhaps this helps someone else :)
I typed: sudo /usr/local/mysql/support-files/mysql.server start
into the terminal and it started the MySQL server successfully and I was able to connect to MYSQL workbench.
You need to sure that Mysql process is running in your system. not sure in MAC but in windows it'called mysqld.exe
well take a look
http://lists.mysql.com/mysql/124371
Most commonly happens when database/server is not running. You need to check your server, or restart it. You can do so if you have mysql workbench under server administration. Check your manual for restarting or starting the server.
On osx 10.6 using mamp pro I solved this by allowing network access in the MySQL tab from the home window. Hope it saves someone the pain too
When trying to use the MySQL Workbench and connect through an SSH tunnel, you will get this error when your SSH connection does not complete successfully (e.g. improper host, password, key file, etc)
A good way to trouble shoot this is to separately test the the ssh connection from the machine you are trying to connect from and establish that you can do so successfully.
Try closing MySQL and running it as the admin. This worked for me.
After making above improvement such as checking if mysql service is running or not, you just need to give a small password while creating connection, it is ' ' or 1 time press on space-bar in case of GUI or workbench.
After which you just need to validate your machine with server (validated HOST).
For that purpose click on 'New Server Instance' and it will configure server/HOST on your behalf itself.
I have done this successfully just a few couple of minutes ago. My workbench software is able to show all pre-installed databases etc now.
Thanks!!!
I solved it! On a mac just go to spotlight search on the top right of the screen and type Mysql. Turn it on.
