I have a problem running MySQL 8 where the error logs are not being written. The contents of /etc/mysql/my.cnf includes:
[mysqld]
log_error_verbosity=2
log_error=/var/log/mysql/error.log
slow_query_log_file=/var/log/mysql/slow.log
long_query_time=5
slow_query_log=1
general_log_file=/var/log/mysql/general.log
general_log=1
With this configuration, both the slow.log and the general.log files are written correctly. The owner of these files is mysql:adm.
However, none of the error logs are written. The only thing that gets written to this file is the system messages when mysql is restarted.
The one thing I see different with error.log is that the owner of this file is mysql:mysql. I tried changing the owner of this file to mysql:adm, but still, no error logs are being written.
Any ideas would be greatly appreciated!

Load data infile has always been a pain in the ass to set up and there does not seem to be standard way to get it to work but I have always been able to get it to work ….eventually except now.
I am struggling with
Error Code: 29. File '/loadinfile/file.csv' not found (OS errno 13 - Permission denied)
The system is as follows:
MySQL version 8.0.29-0ubuntu0.22.04.2
Ubuntu 22.04
The load file directory is owned by mysql:mysql and same with the file and I have tried chmod 757 and even 777
In the config file I have tried the following variations:
secure_file_priv = "/loadinfile/"
secure_file_priv = '/loadinfile/'
secure_file_priv = ""
secure_file_priv = ''
The following is also set :
[mysqld]
local-infile = 1
[client]
loose-local-infile=1
Changing
LOAD DATA INFILE '/loadinfile/file.csv' INTO TABLE table
to
LOAD DATA LOCAL INFILE '/loadinfile/file.csv' INTO TABLE table
changes the error message to:
Error Code: 2. File '\loadinfile\file.csv' not found (OS errno 2 - No such file or directory)
Error Code: 2. File '\loadinfile\file.csv' not found (OS errno 2 - No such file or directory)
Above message indicates that your directory where the file is located is wrong! You must define the full path:
For example In Mac If your file resides on Desktop,It must be like this :
LOAD DATA LOCAL INFILE '/Users/computer_name/Desktop/filename.file_extension' INTO TABLE table
In windows
LOAD DATA LOCAL INFILE 'C:\Users\computer_name\Desktop\filename.file_extension' INTO TABLE table
I hope It solves your problem.
Error Code: 2. indicates invalid file path. Keep the LOCAL INFILE option and either specify the full path of the CSV file or make sure the CSV file path is correct. give it a try with Full path and see if it solves the problem or not.
From MySQL Docs
If LOCAL is specified, the file must be located on the client host.
The client program reads the file, locating it as follows:
If the file name is an absolute path name, the client program uses it
as given.
If the file name is a relative path name, the client program looks for
the file relative to its invocation directory
Edited
Make sure your mysqld.cnf or your main MySQL config file has the following variables
secure_file_priv = ""
local_infile=1
And your Global variable local_infile is OFF, turn it ON.
you can check that if you run this query
SHOW GLOBAL VARIABLES LIKE 'local_infile';
if it is OFF, turn it ON
And lastly, Make sure you restart your SQL service to reflect the changes. you can do that if you execute
service mysql restart
Hope that solves your problem
Internal Server Error
The server encountered an internal error or mis configuration and was unable to complete your request.
Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
You can increase memory limit in 3 ways,
Edit your wp-config.php file
define('WP_MEMORY_LIMIT', '256M'); // if this is not in your wp-config file.
Edit your PHP.ini file
If you have access to your PHP.ini file, change the line in PHP.ini
memory_limit = 256M ; Maximum amount of memory a script may consume (64MB) //If your line shows 64M try 256M:
Edit your .htaccess file
If you don’t have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 256M
Hope this will help you.
it is friday but no weekend yet. :( My colleague is on vacation and I myself am not a MySQL Pro.
So this morning today our pages stopped working and I am trying to fix for hours now but couldn't solve it myself.
So, baseline error is:
"Status: "InnoDB: Fatal: Trying to access page number 62087 in space 0 space name /var/lib/mysql/db/ibdata1, which is outside the tablespace bounds. Byte offset 0, len 16384 i/o type 10.Please check that the configuration matches the InnoDB system tablespace location (ibdata files)""
I did find a quite similar problem here: https://dba.stackexchange.com/questions/183862/trying-to-solve-outside-tablespace-bounds-mysql-error-but-recovering-table-wi
Sadly there is no solution provided.
The command "mysqldump" from the post above won't work anyway, as the whole service is not starting up.
I recreated the DB status from yesterday using snapper -> that is why I absolutely have no clue why it does not work now. Tried the timestamp from Wednesday - same issue.
Configuration reads:
[mysqld]
datadir=/var/lib/mysql/db
socket=/var/lib/mysql/mysql.sock
innodb_data_home_dir = /var/lib/mysql/db
innodb_data_file_path = ibdata1:10M:autoextend
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
# include all files from the config directory
#
!includedir /etc/my.cnf.d
innodb_force_recovery=4
Moving / renaming the original ibdata1 did not solve anything. The thought was that maybe letting the system recreate the file would solve the problem.
Any input on this is highly appreciated.
I do not much care about data loss as long as the service will be running again, which has the highest priority right now.
Thanks a lot

when i try to start the zabbix-server i am getting and run/zabbix/zabbix_server.pid not readable (yet?) error,
ls -al

my zabbix-server config file

Please help. suggest me a solution
I've had this issue when building a zabbix 4.0 server. To fix the issue I made sure that the path to the PID file was correct on '/etc/zabbix/zabbix_server.conf' and '/lib/systemd/system/zabbix-server.service'.
Interestingly restarting the service alone did not get rid of the error. I needed to reboot the server and this fixed the problem.
close the selinux on centos7
It works for me.
just close selinux for this time
setenforce 0
Close selinux forever
vi /etc/selinux/config
SELINUX=disabled
That message only indicates that the server failed to start. Check the server log (/var/log/zabbix/zabbix_server.log according to your config file), it will contain a more meaningful error message.
In my case, it was a issue connecting with the database.
Remove current pid file + be sure that no zabbix_server process is running on your machine.
Zabbix server does not accept special chars like: !##$%^&*()_+,./;'[]}{|":?>< in DBPassword variable.
I've created this config for redis [/etc/redis/map.conf]:
include /etc/redis/ideal.conf
port 11235
pidfile /var/run/redis-map.pid
logfile /var/log/redis/map.log
dbfilename map.rdb
As you can see, it includes /etc/redis/ideal.conf; this file actually exists and we have read permissions.
Also there is another file, slightly different; consider [/etc/redis/storage.conf]:
include /etc/redis/ideal.conf
pidfile /var/run/redis-storage.pid
port 8000
bind 192.168.0.3
logfile /var/log/redis/storage.log
dbfilename dump_storage.rdb
My problem is: I can launch redis-server with storage.conf (and everything works fine), but map.conf leads to the following error:
Reading the configuration file, at line 1
>>> 'include /etc/redis/ideal.conf'
Bad directive or wrong number of arguments
failed
Version of redis is 2.2.
Where did I go wrong?
Sorry guys.
I was using different instances of Redis.
Instance for storage.conf was launched by /usr/local/bin/redis-server, but map.conf launched by /usr/bin/redis-server; second one is broken.
Thank you anyway.
