The problem look like there is no data in the directory  copy at least the mysql directory either from your previous directory or from C  Program Files MySQL MySQL Server 5 5 data   And then try again

If you are trying to run MySql on a Windows 10 installation with a GPT partition  please try this   Todays systems are often running on a disk which is formatted in GPT  This is because Windows 10 needs such a partition to be installed  The problem is that MySql cant deal with this partition style and so it crashes  Here is my workaround    Create a virtual disk  manual here Format this VHD with MBR Install MySql custom on your new VHD  dont forget to create a user for DB    This should be it      Reference Link  Issue with MySql installation on Windows 10

In my instance it had nothing to do with spaces in the file name  I used the MSI installer custom configuration and opted to exclude the default databases  assuming it was just something like Northwind Adventureworks  Nope  it includes the core MySql system database    once I added that to the installation it worked

I have mysql data folder replaced by a windows directory junction  I suspect ib logfile0 1 and or ibdata1 is corrupted   Just try to delete those files and computername err  Then restart mysql service  That s what I did  with success    Copying ibdata1 files  after a full reinstallation of mysql  to the junction dir and replacing dir by the junction  restarting mysql  was not enough   You have to let mysql rebuild those files

The solution was to install MySQL without spaces in installation path  Windows 7  64-bit

I had the same problem  In my case  it was  user error   although the Windows installer should have been smarter about it and prevented me from committing such an error    During installation  if you make changes to the default installation paths  make sure you use the same paths for both the  Server data files  on the Custom Setup screen and then later in the  InnoDB Tablespace Settings  during the  MySQL Server Instance Configuration Wizard

I had the same error and it was caused by non standard characters in the log files path  In order to fix that I found my ini config file  in my case C  ProgramData MySQL MySQL Server 5 6 my ini  and modified keys slow query log file and log-error  After that I managed to start MySQL service succesfully

Experienced the same error  below is the reason and solution that worked for me for mysql-5 7 14-winx64  reason  DATA folder to have some default folders and files which were missing  solution  delete everything from DATA folder  i assume its a fresh installation so backup anything that you need if at all  Then run this from the command prompt and it will create required files and folders  mysqld --initialize --console  now run  mysqld  and it should work well

Also check if all dirs which you wrote in the my ini exists   My problem was that tmpdir doeesn t exist so MySQL daemon falls with error 1067    mysqld  port  3306 tmpdir    C  tmp    In this case C  tmp must exists

In my case  in order to delete a heavy schema from mysql server  just went to C  ProgramData MySQL MySQL Server 5 7 Data and deleted relevant folder  But it was not being deleted because mysqld exe was preventing it  so I stopped mysqld exe  deleted the folder and then all the schemas went disappeared from the list in mysql workbench  No matter how much I tried to restart mysql service  it didnt unless I restored that folder from junk  Hope it helps someone who tried the same shortcut as I did

My issue happened right after a power failure  I got the error 1067 The process terminated unexpectedly  MySQL needless to say did not start  The answer was simple   Open mysql path data Remove  delete  both ib logfile0 and ib logfile1  Start the service

One more thing that prevents the mysqld windows service from running is if you have mysqld exe already running  but not as a service  and occupying port 3306  When the service tries to start and sees that port 3306 is already taken  it fails   Just open up the windows task manager and look for  mysqld exe  under the Processes tab  If you see it  kill it and then try to start the service again   c   gt  net start  servicename    example  c    net start MySQL

In my case  I had chosen a custom path for my log-files in the MySQL installer  I had put the log-files in my user-folder C  Users  MY USERACCOUNT  Documents mysql-logs  and by default  NETWORK SERVICE  or any other non-administrator useraccount in Windows  does not have access to a user s folder   I fixed this by changing security options for the log-folder  giving modify rights read write modify rights to NETWORK SERVICE

Check the file  C  Program Files MySQL MySQL Server 5 1 my ini   The datadir line in my ini should specify a path  Check the contents of that datadir path  Does it contain a folder named  mysql  and another folder named  test    If not  here are two choices    Change the datadir line in my ini to the correct location  This will probably be C  ProgramData MySQL MySQL Server 5 1 data Clean out the existing contents of your datadir path  Copy the contents of the C  ProgramData MySQL MySQL Server 5 1 data to your datadir path  Restarting the mysql service should rebuild your empty database

I ran into the same errors   Similar approach for me   From what I can tell  there is something weird going on with the reference to the datadir in the my ini file   Even when I manually edited it I could not seem to have any effect on it  until I blew EVERYTHING AWAY   Wish I had better news   do a DB backup first       For me the key to getting this to work was   1  Remove the previous installation from settings- gt control panel   Restart your machine   2  Once machine comes back up  forcefully delete the previous installation directory       mine is C  apps MySQL MySQLServer-5 5   as I REFUSE to use c  program files      3  Forcefully delete the previous datadir directory  mine was c  data mysql    4  Forcefully delete the previous default data directory  C  Documents and Settings All Users Application Data MySQL    5  Re-run the install  selected the same installation directory  Skip the instance configurator wizard at the end of the install   6  Make sure the    bin directory gets added to the path  Verify it   7  Manually run the instance configurator wizard     Set the root password  port  3306      It will try to start it  Again  mine FAILED to start      duh   nothing new there      8  Now  manually edit the my ini file in the install directory  and correct the datadir setting to be  datadir  C  Data MySQL    MATCH CAPITALIZATION       9  Verify the service is setup correctly via the command-prompt  sc qc mysql  lt enter gt        Should look like   C  dev cmdz gt sc qc mysql   SC  GetServiceConfig SUCCESS  SERVICE NAME  mysql         TYPE                 10  WIN32 OWN PROCESS         START TYPE           2   AUTO START         ERROR CONTROL        1   NORMAL         BINARY PATH NAME      C  apps MySQL MySQLServer-5 5 bin mysqld  --defaults-file  C  apps MySQL MySQLServer-5 5 my ini  MySQL         LOAD ORDER GROUP             TAG                  0         DISPLAY NAME         MySQL         DEPENDENCIES                 SERVICE START NAME   LocalSystem   10  Copy the contents of the default data-directory created under C  Documents and Settings All Users Application Data MySQL  basically everything in this directory to your desired data directory c  data mysql    Make sure you get the C  Documents and Settings All Users Application Data MySQL mysql directory   This has host frm file  and others     You should end up with a directory now of c  data MySQL mysql     11  Rename the default directory        C  Documents and Settings All Users Application Data MySQL    To       C  Documents and Settings All Users Application Data MySQLxxx    So it cannot find it      12  Say a quick prayer     13  Give it a kick start from command line with  net start mysql   That got it working for me     Best of Luck

I had a problem changing the datadir in my ini for Windows 7    I wanted the data to be stored on a different drive and I was moving this data from another PC by copying the whole folder  I changed datadir to desired drive and saved the my ini file with no problems   But mysql would not start  I opened my ini file again and it appeared to have been changed  Then  I noticed the date on the my ini had not changed  So I had to change the security privileges to give me write access to it   This time when I saved it  the date changed and mysql started up access to all the correct data

I run MariaDB  MySQL compatible  on two machines locally  I m not sure what prompted the error and nothing I tried worked  So I stopped the service  deleted everything in MariaDB s directory  except the data directory  and copied the files from my secondary machine and everything is working well enough as far as I can tell   For a live server it d be a bit different and a super-guru might be able to add an insight comment  e g  something outside of the data directory might have something to do with preventing data corruption or indexes in example    I would just stop the service and copy the entire directory once every month or so and then start the service again

Before messing with too much things  please check the user the service is trying to run as  In my case it was NETWORK this one did not have write permissions to some locations where it was needed  Changing the user to Local System Account did the trick  If the event viewer shows any error like  Can t create test file C  Program Files MySQL MySQL Server 5 6 data XXX lower-test   there is a high probability for this solution to work  Good luck

when looked at mysql log   err file under data folder   i could see the following   21 41 47 UTC - mysqld got exception 0xc0000005   This could be because you hit a bug  It is also possible that this binary or one of the libraries it was linked against is corrupt  improperly built  or misconfigured  This error can also be caused by malfunctioning hardware  Attempting to collect some information that could help diagnose the problem  As this is a crash and something is definitely wrong  the information collection process might fail   I realized i was starting the service while i plugged usb  To be honest  the problem was resolved after i restarted my machine followed by restarting the service  In addition i removed ib logfile0 and ib logfile1 files before my restart  Though the event logger indicated  InnoDB  Your database may be corrupt or you may have copied the InnoDB tablespace but not the InnoDB log files  Please refer to http   dev mysql com doc refman 5 7 en forcing-innodb-recovery html for information      Blockquote   about forcing recovery For more information  see Help and Support Center at http   www mysql com   i do not think so because i never changed any configurations
