This is my problem in mysql when starting service this is from log. I did not yet google solution because FREEBSD OS
It seems like you have hit this FreeBSD bug, which was reported for package mysql57-server-5.7.12.
A workaround is to change the permissions of file /usr/local/etc/mysql/my.cnf to something like 646 (the key point is that others need write permissions).
You can also see this this FreeBSD forum thread for more information..

Sorry my english is not fluent. I am a newbie in MySQL database. I use MySQL 8.0.30 on Windows Server 2022 Datacenter. I have problem that MySQL crashes frequently (the MySQL service stops) always with same error log. I've tried to find the source of the problem but it's not resolved.
For the information I used Grafana Web Server and MySQL on same device with the following specs:
Processor Intel(R) Xeon(R) Silver 4208 CPU # 2.10GHz 2.10 GHz
Installed RAM 16.0 GB (15.6 GB usable)
System type 64-bit operating system, x64-based processor
Please give me an advice to resolve this trouble.
Thanks before
Here is the error MySQL log details :
10:01:25 UTC - mysqld got exception 0xc0000005 ;
Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.

where mysqld died. If you see no messages after this, something went
terribly wrong...

information that should help you find out what is causing the crash.
I have tried reducing the data read and written, then increasing the client connection limit
Rate Per Second = RPS
Suggestions to consider for your my.ini [mysqld] section to possibly avoid unplanned shutdowns.
innodb_thread_concurrency=10 # from 33 for reasonable limit for your 16 available total threads
innodb_redo_log_capacity=96M # from innodb_log_file_size name and 48M limit
**** this is current name rather then deprecated innodb_log_file_size per error log
innodb_buffer_pool_size=8G # from 124M for about 1/2 available RAM to reduce innodb_data_reads RPS of 31.
read_rnd_buffer_size=32K from 256K to reduce handler_read_rnd_next RPS of 63,041
thread_cache_size=128 # from 10 to reduce threads_created RPS of ~ 5
Please view profile for contact info. You have many opportunities to improve performance with additional Global Variable changes.
Would like to hear your story of how you get this much activity in 96 seconds of uptime. :)
i am facing the following error recently. Mysql was hosted by XAMPP in local, and recently getting repetitively Error.

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.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.3.16-MariaDB
key_buffer_size=33554432
read_buffer_size=262144
max_used_connections=11
max_threads=65537
thread_count=9
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 36501 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Once this happen, the XAMPP's MYSQL service will be forced stop. And i will have to restart it again.
Anyone know how to fix/encounter this issue? Any guide or comment will be much appreciate
I’m running WAMP64 on Windows 10 (development machine), with MySQL 5.7.19. I’ve installed the keyring_file plugin. MySQL starts, but the keyring_file is not found, so the following errors:
[ERROR] Plugin keyring_file reported: 'File
'C:/wamp64/bin/mysql/mysql5.7.19/lib/plugin/keyring_file.dll' not
found (Errcode: 13 - Permission denied)' [ERROR] Plugin keyring_file
reported: 'keyring_file initialization failure. Please check if the
keyring_file_data points to readable keyring file or keyring file can
be created in the specified location. The keyring_file will stay
unusable until correct path to the keyring file gets provided'
The file is on the specified path:
My.ini includes:
The variables loads:
The plugin appears to load:
And the mysql service has Local System permission:
I have tried uninstalling and re-installing the plugins, granting broader permissions on the keyring.dll file, and of course I have re-started the MySQL service after each test.
So my question is why am I getting Errcode 13, permission denied? What am I missing here? Thanks.
The issue is that you are specifing the .dll file for the keyring_file_data variable, not the location of a file to use for the keyring. It should be something like:
keyring_file_data=C:/some/path/to/keyring
https://dev.mysql.com/doc/refman/5.7/en/keyring-file-plugin.html
I'm using the MySql Server which comes with Cygwin. No matter whether I start it like this:
mysqld --tmpdir=/cygdrive/c/temp start
or like this:
mysqld start --tmpdir=/cygdrive/c/temp
I always get the error message
151104 15:50:48 [Note] mysqld (mysqld 5.5.45) starting as process 8784 ...
151104 15:50:48 [Warning] Can't create test file /var/lib/mysql/CMTCL033974.lower-test
151104 15:50:48 [Warning] Can't create test file /var/lib/mysql/CMTCL033974.lower-test
It looks as if the --tmpdir option would be ignored.
BTW, the directory /cygdrive/c/temp exists and is writeable.
It seems to be easy: --tmpdir does not affect the location of these files. They always have to be under /var/lib, so I manually created /var/lib/mysql, and the error message disappeared.
However, mysqld now complains about the start parameter, but this is an unrelated issue, where I will open a separate thread for it, if I can't figure it out by myself....
I am getting this error while installing MySQL 5.6.10. I have other versions of MySQL (5.1 and 4.1) installed and there seems to be a conflict in the my.cnf.
Removing /etc/my.cnf is not an option.

================
"log=/var/lib/mysql/mysql.log" is defined in the /etc/my.cnf and cant be removed. (Cant be changed as globally used)
I also tried to install using --defaults-file=/usr/local/mysql5610/my.cnf but that didn't work.
http://dev.mysql.com/doc/refman/5.6/en/server-options.html#option_mysqld_log
The --log option was removed in MySQL 5.6.1 (along with the log system variable). Instead, use the --general_log option to enable the general query log and the --general_log_file=file_name option to set the general query log file name.
In fact, the log option has been deprecated since MySQL 5.1.29 (circa October 2008).
You don't have to remove your my.cnf, but you cannot use the log option anymore. You must change it according to the instructions above, and it will work on all your other instances of MySQL 5.1 and greater.
