MySQL Database won t start in XAMPP Manager-osx

Question

I downloaded XAMPP about a month ago and it was working just fine  Today I installed a voice recognition software and then restarted my computer  Ever since  MySQL won t start in my manager-osx application  It doesn t throw me an in the application log  This is what it says   Stopping all servers    Stopping Apache Web Server     Applications XAMPP xamppfiles apache2 scripts ctl sh   httpd stopped Stopping ProFTPD    Checking syntax of configuration file  Applications XAMPP xamppfiles proftpd scripts ctl sh   proftpd stopped Restarting all servers    Starting MySQL Database     Starting Apache Web Server     Applications XAMPP xamppfiles apache2 scripts ctl sh   httpd started Starting ProFTPD    Checking syntax of configuration file  Applications XAMPP xamppfiles proftpd scripts ctl sh   proftpd started   Both my ProFTPD and my Apache Web Server are running  MySQL isn t  When I go to phpmyadmin  it throws me this error message    2002 - No such file or directory The server is not responding  or the local server s socket is not correctly configured     Please help me  I have no idea what to do   UPDATE    After looking around the internet a bit  I found a similar problem a user had with MAMP  another user recommended killing the mysql process  what ever that means  Could this be a fix to my problem   UPDATE 2    I found the answer to my problem but I can t answer it yet  So here s the answer   1  Open terminal and type  sudo su   and then put in  your password  2  Then type   ps aux   grep mysql    just copy and paste this   3  You will need to get the process id of mysql  There should be number near the top  something like 739 or 8827  4  Kill the process using  kill -9  process id    this should look something like this  kill -9 739  5  Restart MySQL in manager-osx

check the err log on your  Applications XAMPP xamppfiles var mysql  with filename like your machine name local err  if you find something like    Attempted to open a previously opened tablespace  Previous tablespace     uses space ID   the following works for me   edit file    Applications XAMPP xamppfiles etc my cnf  find the  mysqld  section  add one line   innodb force recovery   1  then run  sudo  Applications XAMPP bin mysql server start  everything is ok again   and then the last step    edit the my cnf again and remove the line you just added     innodb force recovery   1   and restart mysql again  Otherwise all your tables will be read only

Just Click on Managed Servers Tab in XAMPP MANAGER   Now select MySQL Database  Click on configure on right side   Change port from 3306 to 3307 and it will work

User · Answer

It might be the possibility that your voice recognition software has a installer of mysql internally and when u installed this software  it has installed mysql too and added it to the service and this mysql service starts once your system starts  So now u r having two mysql servers  one from voice recognition software and second is from XAMPP  that s why killing the previous process  mysql service   solved your problem  But this is not a permanent solution  you have to repeat it every time when ever you start your machine  So better is to find out that mysql server  service  and change its port no  OR change settings so that mysql service should not start when your machine start  but might be your voice recognition software won t work properly   I hope it will help you   Cheers

I am running XAMPP 5 6 3-0 for OS X Yosemite 10 10 2 and ran into the same issue twice  the first time was with Mavericks  With a bunch of different solutions to the issue with MySQL Database not starting using Manager App I wanted to confirm what had worked for me  The workaround that always worked and forced MySQL to start was by opening Terminal and using   sudo  Applications XAMPP xamppfiles bin mysql server start  I had the Manager App open and started ProFTPD and Apache and then ran the sudo command   The other suggestion by wishap that worked was to locate  Applications XAMPP xamppfiles etc my cnf file and change the permissions for  everyone  to Read only    The other problem I had that seems to be another issue with many solutions is the problem after everything is started then entering localhost which brings me to the xampp splash screen and then nothing  The only thing that worked for me  to at the very least  to access the phpMyAdmin page is by entering localhost phpmyadmin  I hope this helps others reading through a bunch of threads for an answer    Regards   Erik

It s because of the firewall settings     Go to system preferences- Security and Privacy Click on Firewall-  Firewall Options If you have Block all incoming connections checked then uncheck it Check automatically allow signed software to receive incoming connections  hit the lock save your settings Open up xampp  go to manage servers  hit start all  and you will be prompted to accept or deny the incoming connection of mysql and ProFTPD   6 Accept the connection

close XAMPP control sudo killall mysqld sudo  Applications XAMPP xamppfiles bin mysql server start

User · Answer

It can cause because of the software you installed or may be any other software which is using the same port 3306  This 3306 port is used by the Mysql in XAMPP  Similar kind of problem I faced for Apache  I was running skype and trying to run the XAMPP but the skype uses the same port as Apache so it was not working  Then I sign out from skype then the port was free and the apache started  So you should look for the software in you laptop which is blocking or making busy this port  Free that port by closing the software and then run XAMPP and It will work

Restarting the computer  or using the  kill  commands listed above solve the problem  AS for preventing it from happening  I ve found this occurring anytime my computer goes to sleep  The port is obviously kept reserved  and then on wake  mysql tries to reconnect to that port  but can t  This could be your problem also

This could be due to the fact that another instance of mysqd is already running in your mac-book-pro  MacOs-10   It s next to impossible to kill pkill mysqld or       I tried that route many times  with out any success  Finally the following worked for me    launchctl unload -w  Library LaunchDaemons com oracle oss mysql mysqld plist   wait a few minutes and check with   ps -ef grep mysqld   It should be gone

User · Answer

There s been a lot of answer  but I think I found what is causing it  at least for me  It looks like if you put your computer to sleep  or it falls asleep on its own   when it reopens  it tries to open the the mysql process again  At one point I looked at my activity monitor and I had 5 instances running - killing all of them and then starting mysql works

User · Answer

You seem to have found a work-around by killing the process  but make sure you check for free space on your MySQL partition  If your logs or db files are consuming all your drive space  mysqld will not start

User · Answer

All the answers stated above in relation to changing the port number are in this situation the best way to solve this problem since you need your voice recognition software to coexist with MAMP  However  you must remember that changing this port number is going to affect all you subsequent connections to MySQL  i e  terminal php code phpmyadmin etc   Hence It would be advisable to change the port on which the voice recognition software runs  Hope this was helpful
