I have added secure-file-priv = "" to my nano /etc/my.cnf file for mysql and now I'm not able to remove it.When I remove that line and try to save it, it's asking me to write to a file and the changes are not saved
I tried to uninstall and install mySQL but due to this the server is not able to start.
Error Messages:
my_print_defaults: [ERROR] Found option without preceding group in config file /etc/my.cnf at line 1.
my_print_defaults: [ERROR] Fatal error in defaults handling. Program aborted!

Is there any way I can fix this error, I tried a lot but couldn't find any solution
"errors when saving" are often linked to access rights issues.
run ls -l /etc/my.cnf to confirm that this file is owned by root.
in the vast majority of cases, system wide configuration files are owned by root. To edit a root file, you should do it with root privileges, e.g :
sudo nano /etc/my.cnf
(that's probably how you were able to add the config parameter in the first place)
OS: Mac OS X Hi Sierra(10.13.1)
MySQL: 5.7.20 (install by homebrew)
I want to enable bin log, so I should edit my.cnf file,
I typed below command to find my.cnf file
mysql --verbose --help | grep my.cnf
and result
/etc/my.cnf /etc/mysql/my.cnf /usr/local/etc/my.cnf ~/.my.cnf
/etc/my.cnf, /etc/mysql/my.cnf isn't exist in my mac.
So, I edit /usr/local/etc/my.cnf file.
[mysqld]
bind-address = 127.0.0.1
log-bin = ~/log
and I start mysql but it can't start.
mysql.server start
Starting MySQL
... ERROR! The server quit without updating PID file (/usr/local/var/mysql/*.pid).
When I remove bin-log in my.cnf, it can start!
How can I enable bin log??

I missed server-id property in my.cnf...

chown -R mysql:mysql /var/lib/mysql
/etc/init.d/mysqld start

systemctl restart systemd-logind
rebooted the server
Still no luck.

/etc/init.d/mysql stop
service mysql stop
killall -KILL mysql mysqld_safe mysqld
/etc/init.d/mysql start
service mysql start
I had the same error, the problem was because I no longer had disk space.
to check the space run this:
$ df -h
Then delete some files that you didn't need.
After this commands:
service mysql start
systemctl status mysql.service
mysql -u root -p
After entering with the root password verify that the mysql service was active
I met this problem today, and fix it with bellowed steps.
1, Check the log file /var/log/mysqld.log
tail -f /var/log/mysqld.log
2017-03-14T07:06:53.374603Z 0 [ERROR] /usr/sbin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2 - No such file or directory)
2017-03-14T07:06:53.374614Z 0 [ERROR] Can't start server: can't create PID file: No such file or directory
The log says that there isn't a file or directory /var/run/mysqld/mysqld.pid
2, Create the directory /var/run/mysqld
mkdir -p /var/run/mysqld/
3, Start the mysqld again service mysqld start, but still fail, check the log again /var/log/mysqld.log
2017-03-14T07:14:22.967667Z 0 [ERROR] /usr/sbin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 13 - Permission denied)
2017-03-14T07:14:22.967678Z 0 [ERROR] Can't start server: can't create PID file: Permission denied
It saids permission denied.
4, Grant the permission to mysql
chown mysql.mysql /var/run/mysqld/
5, Restart the mysqld
# service mysqld restart
Restarting mysqld (via systemctl): [ OK ]
These are the steps I took to correct this:
Back up your my.cnf file in /etc/mysql and remove or rename it
sudo mv /etc/mysql/my.cnf /etc/mysql/my.cnf.bak
Remove the folder /etc/mysql/mysql.conf.d/ using
sudo rm -r /etc/mysql/mysql.conf.d/
Verify you don't have a my.cnf file stashed somewhere else (I did in my home dir!) or in /etc/alternatives/my.cnf use
sudo find / -name my.cnf
Now reinstall every thing
sudo apt purge mysql-server mysql-server-5.7 mysql-server-core-5.7
sudo apt install mysql-server
In case your syslog shows an error like "mysqld: Can't read dir of '/etc/mysql/conf.d/'" create a symbolic link:
sudo ln -s /etc/mysql/mysql.conf.d /etc/mysql/conf.d
Then the service should be able to start with sudo service mysql start.
I hope it work
In my particular case, the error was appearing due to missing /var/log/mysql with mysql-server package 5.7.21-1 on Debian-based Linux distro. Having ran strace and sudo /usr/sbin/mysqld --daemonize --pid-file=/run/mysqld/mysqld.pid ( which is what the systemd service actually runs), it became apparent that the issue was due to this:
2019-01-01T09:09:22.102568Z 0 [ERROR] Could not open file '/var/log/mysql/error.log' for error logging: No such file or directory
I've recently removed contents of several directories in /var/log so it was no surprise. The solution was to create the directory and make it owned by mysql user as in
$ sudo mkdir /var/log/mysql
$ sudo chown -R mysql:mysql /var/log/mysql
Having done that I've happily logged in via sudo mysql -u root and greeted with the old and familiar mysql> prompt
if your problem not fix, you can try check more problem.
maybe mysql crash , like this :
you can check log in
sudo cat /var/log/mysql/error.log
or you check
sudo ls /var/crash
try
sudo chown mysql:mysql -R /var/lib/mysql
then start your mysql service
systemctl start mysqld

I was also facing same issue .
root#*******:/root >mysql -uroot -password

I found ROOT FS was also full and then I killed below lock session .

Finally Issue solved .
open my.cnf and copy the log-error path
then check the permission for the copied log file using
$ ls -l /var/log/mysql.log
if any log file permission may changed from mysql:mysql, please change the file permission to
$ chown -R mysql:mysql /var/log/mysql.log
then restart the mysql server
$ service mysql restart || systemctl restart mysqld
note: this kind of errors formed by the permission issues. all the mysql service start commands using the log file for writing the status of mysql. If the permission has been changed, the service can't be write anything into the log files. If it happens it will stopped to run the service
remove any command of "secure_file_priv" in /etc/mysql/my.cnf and restart mysql.
If you want to use a file in mysql, copy those files to the main folder.
The main folder is obtained this way : SHOW VARIABLES LIKE "secure_file_priv";
You can purge all mysql-related packages and reinstall them with the following commands:
PACKAGES="mysql-server mysql-community-server mysql-community-server-core mysql-client mysql-client mysql-community-client mysql-community-client-core mysql-common mysql-community-client-plugins php-mysql"
apt purge $PACKAGES
echo "any remaining installed packages:"
dpkg -l|grep ii|grep mysql
apt install --reinstall mysql-common
apt install $PACKAGES
If there are any remaining packages (apart from mysql-core), add those to your list
Backup your config or data and reinstall mysql
sudo apt remove --purge mysql-server
sudo apt purge mysql-server
sudo apt autoremove
sudo apt autoclean
sudo apt remove dbconfig-mysql
sudo apt-get remove --purge mysql* -y
sudo apt-get autoremove -y
sudo apt-get autoclean
Then install it again.
That works here.
i have got the same "systemctl status mysql.service" and "journalctl -xe" for details. ERROR.
after repeated deinstallation and installation does not work at all.
but this one work well> https://linuxtut.com/en/5a5b0f46620ae1b27b10/
you just need to remove everything from my.cnf file except [mysqld] and start the server. this really work. but you might not have the password for root in that case skip-grant-tables and restart server in safe mode and use mysql and
update mysql.user set authentication_string=null where user='root' and then can alter user 'root'#'localhost' identified by 'your_$$new_99pwd#';
then login to secure mode and then you can create new user.
Also don't forget to check on your docker containers, for me it was my docker has mysql running on the background.
Connect to the server using SSH.
Stop the affected MySQL service and the service plesk-web-socket to prevent it from attempting to start MySQL:
service mysql stop || service mariadb stop && service plesk-web-socket stop
Back up all the MySQL data storage files. By default, they are located in the directory /var/lib/mysql/.
For example:
cp -a /var/lib/mysql /root/mysql_backup
Add the parameter innodb_force_recovery to the section [mysqld] of the MySQL configuration file. This option allows starting MySQL service in the recovery mode and try creating dumps of databases.
For example:
vi /etc/my.cnf
[mysqld]
innodb_force_recovery = 2
Start the MySQL service.
after having tested several solutions without success, the one that finally worked is the following:
you can load the default configuration of your apache server
sudo a2ensite 000-default.conf
sudo a2dissite my.conf
systemctl reload apache2
then reload the configuration for your website
sudo a2ensite my.conf
sudo a2dissite 000-default.conf
systemctl reload apache2
I had the same issue and after hours the solution was for me:
Open this file nano /etc/mysql/my.cnf
#I use mysql service if you use mysqld service, type mysqld instead of mysql
[mysql]
innodb_force_recovery = 1
Had the same problem. Solved as given below.
Use command :
sudo tail -f /var/log/messages|grep -i mysql
to check if SELinux policy is causing the issue. If so, first check if SELinux policy is enabled using command #sestatus. If it shows enabled, then disable it.
To disable:
# vi /etc/sysconfig/selinux
change 'SELINUX=enforcing' to 'SELINUX=disabled'
restart linux
check with sestatus and it should show "disabled"
Uninstall and reinstall mysql. It should be working.
so i've been trying for a good 2-3 hours now to fix several issues when it came to installing mysql.
Now, i'm currently stuck on this one:
when typing: mysql.server restart
this prints out in the terminal:

Pasting the code that was in my.cfn and using sublime text 2 to save it did the trick...
Hi i have been trying this for hours upon hours, this forum is my last resort
sfter googling hundreds of pages.
PROBLEM:
Sorry for the length but i am supplying in detail of what i have tried
I have set up mysql and its working fine, i now need to change the data-storage to point at my External HD.
With mac osx there is no default my.cnf so i copied
my-huge.cnf from /usr/local/mysql-5.1.53-osx10.6-x86/support-files, now if it makes any odds i also have a 'mysql' folder in local also.
when i place and rename my-huge.cnf into /etc
i renamed it to my.cnf like instructed,
it works as normal if i dont add a datadir field which looks like this
datadir= /Volumes/Elements/database,
i have also copied my old data to my new location using
sudo cp -R -p /var/lib/mysql /Volumes/Elements/database
Everything workds fine unless i add the field datadir = /Volumes/Elements/database
to the my.cnf file, if i do i get the error
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
my.cnf file looks like the following
Macintosh-100:support-files seanf$ cd /etc
Macintosh-100:etc seanf$ sudo nano my.cnf
Password:
Macintosh-100:etc seanf$ nano my.cnf
Macintosh-100:etc seanf$ my.cnf > /Desktop/blah.txt
-bash: /Desktop/blah.txt: No such file or directory
Macintosh-100:etc seanf$ my.cnf < /Desktop/blah.txt
-bash: /Desktop/blah.txt: No such file or directory
Macintosh-100:etc seanf$ nano my.cnf

[mysqld]l
datadir = /Volumes/Elements/database
port = 3306
socket = /tmp/mysql.sock
skip-locking
key_buffer_size = 384M
etc....
I hope someone can shed light on this, i have an assignment due and have spent 2 days trying to get this working on my external
Also even when mysql is working and i type mysqld i get errors if this is an issue?
Macintosh-100:lib s$ mysqld

Thanks for your time i hope an expert can answer this
Though I haven't played with datadir property but I've changed data storage location to the external HD by mounting default location to it as follows:
Backup your current data directory
Delete everything from your data directory
Mount it to your external HD (mount /var/lib/mysql/data /dev/XXX)
I've done it at Ubuntu Server. When changing InnoDB specific directories I've noticed that one have to be careful with rights (apparmord in case of ubuntu). When mysql cannot perform some filesystem operation I find its error messages very misleading. Sometimes it is really helpful to study it's error.log (/var/log/mysql/error.log in my case).
Hope this helps you to resolve your issue ASAP.
Use:
rsync -Pa /var/lib/mysql /Volumes/Elements/database
instead of:
cp -R -p /var/lib/mysql /Volumes/Elements/database
"rsync -a" can keep some permissions important for mysql.
