I was getting an error that server quit without updating pid file. So I thought I would uninstall it and install it again.
I had installed it with homebrew last time so I did:
brew uninstall mysql
and to install it I did:
brew install mysql
Even after this however, I am still getting the same error.
$ mysql.server start
Starting MySQL
. ERROR! The server quit without updating PID file (/usr/local/var/mysql/Tirths-MBP.fios-router.home.pid).
If this mysql like a linux binaries; Try to regen PID with mysqld_safe as :
stop server
bin>$./mysql.server stop
regen PID file :
bin>$./mysqld_safe -u youruser&
then try to start mysql as :
bin>$./mysql.server start
p.s.
...and do you have etc/my.cnf file gen-ed ? It would be more helpful you to provide logs;
Hope this helps; Report your results please;
I know this is a widelly answered question but I cannot find one solution that apply to my case.
On OSX El Capitan, I recently switched from a MAMP install to a "manual" install of MySQL, using the dmg package (version 5.7.11).
Now I want to modify the datadir to a custom location ; it used to work but I stopped the server and it doesn't want to start anymore. I tried launching it using:
sudo mysql.server start
sudo mysqld_safe
...but I always get this error: The server quit without updating PID file (/Users/xxx/Documents/dev/MySQL/data/xxx.pid). But it starts whan I set back the datadir to its original location! (which is /usr/local/mysql/data)
First time I had this issue it was clearly documented in the .err file (error 13 if I remember well, which is an access problem) and it was fixed by the magic combination of sudo chown -R _mysql:wheel data/ and sudo chmod -R 777 data/. Now both original and custom datadir have the same owners (user and group) and same read/write permissions. But server will start for one and not for the other? And the .err file only logs:
mysqld_safe Starting mysqld daemon with databases from /Users/xxx/Documents/dev/MySQL/data
mysqld_safe mysqld from pid file /Users/xxx/Documents/dev/MySQL/data/xxx.pid ended
Which doesn't helps me much.
Any ideas please?
I have problem mysql starting, i was update to El captian on mac.
In terminal,
brew install mysql
mysql.server start
but it not working
this is error message.
Starting MySQL... ERROR! The server quit without updating PID file(/usr/local/var/mysql/Heo-MacBook-Pro.local.pid).
help me please!
I had the same problem using brew command to start mysql service.
If you are using MacOS, go to System Preferences and click on MySQL icon. Probably you'll see information message about permission denied in some directories. All you need to do is to give permission to that.
That's worked for me.
Open your terminal
Execute this command: sudo chown -R mysql /usr/local/mysql/data
Try this first:
/usr/local/var/mysql/support-files/mysql.server restart
If that doesn’t fix
Remove or backup the /etc/my.cnf
also try this method:
sudo /usr/local/var/mysql/support-files/mysql.server start
Starting MySQL
. ERROR! ....................
remove the .err files like so:
rm *.err /usr/local/var/mysql/data/
Solution working for my case:
Check your error log at /usr/local/var/mysql/Heo-MacBook-Pro.local.err
If there is something like this in the log: ...[Note] Unable to delete pid file: Permission denied..., which means mysql does not have the permission to your mysql folder
Use the following command in terminal to grant the permission: sudo chown -R mysql /usr/local/var/mysql/
The Problem could also be a version mismatch. My db was installed with Homebrew as version 5, later unintentionally upgraded to version 8.
Check the most recent error log at /usr/local/var/mysql/<your-computers-name.some.domain>.err
You can conveniently read the last couple of lines (e.g. 40) of the file with tail -n 40 <your-computers-name.some.domain>.err
You may find a hint about upgrading istructions in this case.
I know there are a lot of similar problems, but I have to post this because I am not finding a solution yet. Below is what happens when I try to run mysql. Not using homebrew here! I originally fixed the problem by killing the process ID for mysqld, but since I shut my computer down and relocated, then restarted, I am getting this error again. It seems to be the same except the difference with this error is the local.pid part. This was not in my original error message and wandering how to fix this?
Original error fixed by killing the process ID:
ERROR! The server quit without updating PID file (/Applications/XAMPP/xamppfiles/var/mysql/genevieve-ouellons-macbook-pro.pid)
The new error after shutdown, relocate and trying to start:
genevieve-ouellons-macbook-pro:bin genevieveouellon$ cd /Applications/XAMPP/xamppfiles/bin
genevieve-ouellons-macbook-pro:bin genevieveouellon$ ./mysql.server start
Warning: World-writable config file '/Applications/XAMPP/xamppfiles/etc/my.cnf' is ignored
Starting MySQL
. ERROR! The server quit without updating PID file (/Applications/XAMPP/xamppfiles/var/mysql/genevieve-ouellons-macbook-pro.local.pid).
Anyone have this problem?
Thanks
It worked by using these two commands:
cd /Applications/XAMPP/xamppfiles/bin
sudo ./mysql.server start
Using sudo is the keyword that made the difference this time around.
sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start
Above command worked in my case, only if the port is empty..
If this results error, restart server/mac and try the above command.. Hope this helps for someone..
Might've been deleted when you manually restarted mysql or renamed your machine. Not sure about XAMPP but when using mysql on OSX this is my go-to..
cd into /Applications/XAMPP/xamppfiles/var/mysql/
rm -rf *.local.err (deletes file)
touch YOURUSERNAME.local.pid (generates *.local.pid file the error thrown was complaining about)
cd back into your project and restart mysql using mysql.server start
Finally solved this issue... (3 days later)
Open up YOURUSERNAME.local.err in /Applications/XAMPP/xamppfiles/var/mysql/ with a text editor.
I had "InnoDB: Your database may be corrupt or you may have copied the InnoDB tablespace but not the InnoDB log files"
Then follow instructions on http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html as it states in the log file
Add innodb_force_recovery = 2 after line: [mysqld] to your my.cnf located in /XAMPP/xamppfiles/etc/
Then sudo /Applications/XAMPP/xamppfiles/bin/mysql.server start
Give it a minute and it should repair itself
Comment out with #innodb_foce_recovery = 2 in my.cnf
Unfortunately none of possible solutions did not helped me.
Still the Mysql was not able to start and in terminal I saw only /Applications/XAMPP/xamppfiles/var/mysql/: "ERROR!" without any further info
I simply reinstalled XAMPP again - worked
I am having an issue where MySQL isn't starting on my QNAP NAS.
I found this first by not being able to log in through phpMyAdmin - was getting error:
#2002 Cannot log in to the MySQL server
I then went to attempt to start mysql, as I guess this is a common issue with this, but it just gave a generic error.
I went through troubleshooting the mysql.sock file and everything, changing its permissions, but nothing is working.
I have rebooted my NAS many times.
I eventually tried to restart mysql. In doing so I get:
ERROR! MySQL manager or server PID file could not be found!
I can't find anything specific to the QNAP or any general type troubleshooting for this. Everything I find seems to be OSX related.
After a lot of searching, I was able to fix the "PID file cannot be found" issue on my machine. I'm on OS X 10.9.3 and installed mysql via Homebrew.
First, I found my PID file here:
/usr/local/var/mysql/{username}.pid
Next, I located my my.cnf file here:
/usr/local/Cellar/mysql/5.6.19/my.cnf
Finally, I added this line to the bottom of my.cnf:
pid-file = /usr/local/var/mysql/{username}.pid
Hopefully this works for someone else, and saves you a headache! Don't forget to replace {username} with your machine's name (jeffs-air-2 in my case).
I tried everything above, but saw no results until I got a hint from here: https://superuser.com/questions/159486/how-to-kill-process-in-mac-os-x-and-not-have-it-restart-on-its-own
I eventually went over to the activity monitor in my Mac, force Quit the PID, and ran the command:
sudo /usr/local/mysql/support-files/mysql.server restart
The magic was done!!!
If you have installed MySQL using brew the best way to go would be with homebrew
brew services restart mysql
after you run that command, all the problems that the update generated will be resolved
I ended up figuring this out on my own.
In searching for my logs I went into
cd /usr/local/mysql/var
In there I found the file named [MyNAS].pid (replace [MyNAS] with the name of your NAS.
I then ran the following to remove the file
rm -rf /usr/local/mysql/var/[MyNAS].pid
I then restarted mysql
[/usr/local/mysql/var] # /etc/init.d/mysqld.sh restart
/mnt/ext/opt/mysql
/mnt/ext/opt/mysql
Try to shutting down MySQL
ERROR! MySQL manager or server PID file could not be found!
/mnt/ext/opt/mysql
Starting MySQL. SUCCESS!
I tested everything and it all works like a charm again!
Run the below commands and it will work.
Go to terminal and type
sudo chown -RL root:mysql /usr/local/mysql
sudo chown -RL mysql:mysql /usr/local/mysql/data
sudo /usr/local/mysql/support-files/mysql.server start
Just run mysqld (don't run as root) from your terminal. Your mysql server will restart and reset everything like shown in the picture below:
And use a command like so:
mysql -u root -h 127.0.0.1
ERROR! MySQL server PID file could not be found!
This might be due to issues with disk space, disk inode usage or innodb corruption which may lead to the error.
The issue was with the pid file and the solution was:
SSH login to server as a root
Create directory /var/run/mysql
mkdir /var/run/mysql
3) Create a file with name as mysqld.pid
touch mysqld.pid
Change its ownership and group to mysql:mysql
chown mysql:mysql mysqld.pid
Restart MySQL service
Done!
I had the same issue. It turns out I added incorrect variables to the my.cnf file. Once I removed them and restarted mysql started with no issue.
Check if your server is full first, thats a common reason (can't create the PID file because you have no space). Run this to check your disk usage..
df -h
If you get something like this, you are full..
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 40G 40G 6.3M 100% /
In that case, you need to start looking for what to delete to make room, or add an additional drive to your server.
Nothing of this worked for me. I tried everything and nothing worked.
I just did :
brew unlink mysql && brew install mariadb
My concern was if I would lost all the data, but luckily everything was there.
Hope it works for somebody else
Note: If you just want to stop MySQL server, this might be helpful.
In my case, it kept on restarting as soon as I killed the process using PID. Also brew stop command didn't work as I installed without using homebrew. Then I went to mac system preferences and we have MySQL installed there. Just open it and stop the MySQL server and you're done. Here in the screenshot, you can find MySQL in bottom of system preferences.
I know this is an older post, but I ran into the ERROR! MySQL server PID file could not be found! when trying to start MySQL after making an update to my.cnf file. I did the following to resolve the issue:
Deleted my experimental update to my.cnf
Deleted the .net.pid and .net.err files.
delete /usr/local/var/mysql/**<YourUserName>**-MBP.airstreamcomm.net.*
Ensured all MySQL processes are stopped.
ps -ax | grep mysql
kill **<process id>**
Started MySQL server as normal.
mysql.server start
First find PID of mysql service
ps aux | grep mysql
Then, you have to kill process
sudo kill <pid>
After you again start mysql service
mysql.server start
After doing setup of PHPMyAdmin, I was also facing the same problem,
Then I just stopped the MYSQL server by going into System settings, and then started again, and it worked.
root#host [~]# service mysql restart
MySQL server PID file could not be found! [FAILED]
Starting MySQL.The server quit without updating PID file (/[FAILED]mysql/host.pxx.com.pid).
root#host [~]# vim /etc/my.cnf

innodb_file_per_table=1
innodb_force_recovery = 1
Result

I have the same problem. I found the file {username}.local.err instead of {username}.local.pid inside /usr/local/mysql, then i changed the name *.err to *.pid and it works fine.
Starting MySQL.
SUCCESS!
My OS El Capitan 10.11.5
If you're using MySQL Workbench, the mysql.server stop/restart/start will not work.
You will need to login into the workbench and then click "shutdown server". See image attached.
I was able to solve this on OS X by shutting down the existing mysql.server that was running:
mysql.server stop
The starting:
mysql.server start
From there I could run mysql.server restart without throwing the ERROR.
