MySQL 数据库不会在 XAMPP Manager-osx 中启动

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

Answer 1

这应该有效：
sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Answer 2

Minimal Guide

1. sudo killall mysqld

2. manager-osx > start mysql

---

If that didn't work...

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Google the error...

---

Examples:

Error:

ERROR! The server quit without updating PID file (/Applications/XAMPP/xamppfiles/var/mysql/<computername>.local.pid)

My Solution:

In /Applications/XAMPP/xamppfiles/etc/my.cnf change user = <uid> s that <uid> is uid from id command.

$ id
uid=...

$ vim /Applications/XAMPP/xamppfiles/etc/my.cnf
...

Answer 3

If these commands don't work for you:

sudo killall mysqld
sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Try this:

For XAMPP 7.1.1-0, I changed the port number from 3306 to 3307.

1. Click on Manage Servers
2. Select MySQL Database
3. Click on Configure on your right
4. Change your port number to 3307
5. Click OK
6. Close your Control Panel and relaunch it.

You are now good to go.

Answer 4

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

Answer 5

I've tried all these methods with no luck (including of course rebooting) but when I

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

I simply get:

Starting MySQL
. ERROR! 

Not exactly the most helpful information!

Answer 6

尝试在终端中运行这两个命令：

1. sudo killall mysqld
2. sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Answer 7

For me the following worked: Change permission into 'read only' for 'everyone' to the file /Applications/XAMPP/xamppfiles/etc/my.cnf . Then start MySQL from XAMPP manager.

Answer 8

I first couldn't manage to kill mysql daemon with the commands posted here. So I remembered my linux times and did the following:

I monitored the running processes by running top in one terminal window. Then I killed mysqld via sudo killall mysqld (screw the PID ;-) ) in another and restarted via sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start .

Answer 9

1. close XAMPP control
2. sudo killall mysqld
3. sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Answer 10

it happened to me. and

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

not work for me.

so, i reinstall the xampp, then fix it.

attention:

reinstall the xampp, will not delete mysql data, no need to worry about that.

Answer 11

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.

Answer 12

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start    

这对我有用。

Answer 13

I had success with easy killing all active mysql processes in Monitor Activity tool:

1) close XAMPP control

2) open Monitor Activity

3) select filter for All processes (default is My processes)

4) search for: mysql

5) force quit all the mysql

6) relaunch XAMPP control and launch apache again

Enjoy

Answer 14

从终端尝试这两行

1. sudo killall mysqld
2. sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start

Answer 15

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.

Answer 16

What I did was the following: In XAMPP Control Panel I edited the my.ini file of configuration of MySql and changed the port from 3306 to 3307 and it worked, hope it helped!

Edit: after you save this changes be sure that the service is off and then restart the service. I had this same problem when I installed MySQL, it's just the port.

Answer 17

I encountered this problem just now. I checked log file and found it is caused by the server was not shutdown correctly. So I found this http://rivenlinux.info/how-to-recover-innodb-corruption-for-mysql/ and add a simple configuration "innodb_force_recovery = 1" in [mysqld] in my.cnf. Then the problem was solved.

The log file is located /Applications/XAMPP/xamppfiles/var/mysql and it named accroding to your server name. Just link this XXX-MacBook-Pro.local.err

Answer 18

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 (ie, 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.

:)

Answer 19

if you are getting this error

.............ERROR! The server quit without updating PID file 

Try this

Go to /Applications/XAMPP/xamppfiles/var/mysql/

if there is no file with the name Your_Username.local.pid

Your_Username should replace with your Mac Username

Create a file with this name

Then try

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start    

its worked for me

Answer 20

It had the same problem, all I did was give read-only permissions for ALL users (system included) and all items included in the following folders:

/Applications/XAMPP/xamppfiles/etc
/Applications/XAMPP/xamppfiles/sbin

and relaunch XAMPP control and launch mysql server again or

sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start   

Answer 21

I have same problem and get this error in hostname.err in directory /Applications/XAMPP/xamppfiles/var/mysql

2016-09-06 15:32:45 140735322399488 [Note] Plugin 'FEEDBACK' is disabled. 2016-09-06 15:32:45 140735322399488 [Note] Heuristic crash recovery mode 2016-09-06 15:32:45 140735322399488 [Note] Please restart mysqld without --tc-heuristic-recover 2016-09-06 15:32:45 140735322399488 [ERROR] Can't init tc log 2016-09-06 15:32:45 140735322399488 [ERROR] Aborting

2016-09-06 15:32:48 20004 mysqld_safe mysqld from pid file /Applications/XAMPP/xamppfiles/var/mysql/hostname.pid ended

Then I removed tc.log and It works fine after restart mysql through manager-osx

Answer 22

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!

Answer 23

on

macOs High Sierra

if mysql is not getting started from manager- oxs and have tried direct command ie

sudo /Applications/XAMPP/bin/mysql.server start

too than go to path edit

/Applications/XAMPP/xamppfiles/etc/

find file :

my.cnf

edit it

under the [mysqld] section, add following line:

innodb_force_recovery = 1

after it save and run or can be done from manager-osx

sudo /Applications/XAMPP/bin/mysql.server start

it should start the mysql.

once its run you need to again edit the

my.cnf

file and remove the line just added

innodb_force_recovery = 1

stop and start mysql again. by command

sudo /Applications/XAMPP/bin/mysql.server start 

or by manager-osx

it will be working fine.

Answer 24

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 ur 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

Answer 25

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.

Answer 26

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.

Answer 27

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

Answer 28

试试这个， sudo service mysql stop它将停止任何其他 mysql 服务，然后重新启动 xampp

Answer 29

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.

Answer 30

It had the same problem, all I did was give read-only permissions for all users and all items included in the following folders:

/Applications/XAMPP/xamppfiles/etc
/Applications/XAMPP/xamppfiles/sbin

Answer 31

Well, sometime there is just ERROR! message is shown in mysql comment on terminal. Then, just reinstall (overwrite) XAMPP, then it can be solved.
