Somebody please help,
mysqld just crash recently. How to troubleshoot this issue?
It's my first-time to encounter this problem.
After a couple of minutes
screenshot_mysqld_service
I rechecked for mysqld status
sudo systemctl status mysqld
status_mysqld_service
And I just checked for syslog and this is what I got

I have a problem: I can't do anything in a database.
It will return the following directly to me when any action is currently performed, But this error seems to be only targeted at one of my databases:
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
Connection id: 8
Current database: gomeet
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/home/mysql/software/mysql.sock' (111)
ERROR:
Can't connect to the server
It seems that I send any instruction in the gomeet database and dataserver.err will return me a similar error:
InnoDB: Error: trying to access page number 0 in space 3090,
InnoDB: space name gomeet/api_worker_face_back,
InnoDB: which is outside the tablespace bounds.
InnoDB: Byte offset 0, len 16384, i/o type 10.
InnoDB: If you get this error at mysqld startup, please check that
InnoDB: your my.cnf matches the ibdata files that you have in the
InnoDB: MySQL server.

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.
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.
key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=40
max_threads=1500
thread_count=40
connection_count=40
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 604688 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

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

Adding this line into my.cnf file solves your problem.
This is useful when the columns have large values, which cause the issues, you can find the explanation here.
On Windows this file is located at: "C:\ProgramData\MySQL\MySQL Server 5.6"
On Linux (Ubuntu): /etc/mysql
Check this out: https://dev.mysql.com/doc/refman/8.0/en/replication-features-max-allowed-packet.html
I have the following docker-compose.yml file.
I would like to buildthem and connect to DB
version: '3'
services:
api-server:
build: ./api
links:
- 'db'
ports:
- '3000:3000'
volumes:
- ./api:/src
- ./src/node_modules
tty: true
container_name: api-server
db:
build:
context: .
dockerfile: ./db/Dockerfile
restart: always
hostname: db
environment:
MYSQL_ROOT_PASSWORD: test
MYSQL_USER: root
MYSQL_PASSWORD: test
MYSQL_DATABASE: db
volumes:
- './db:/config'
ports:
- 3306:3306
container_name: db
After docker-compose build
then docker-compose up -d
And then `docker exec -it api-server sh'
I could enter containers. and tried
yarn ts-node node_modules/.bin/typeorm migration:show
typeorm command which connect to DB
But it returned
Error during migration show: Error: ER_ACCESS_DENIED_ERROR: Access denied for user 'root'#'172.18.0.3' (using password: YES)
Are there any way to fix it?
Where is the wrong point of it ?
Thanks

The reason is in MySQL database mysql, table users. The user you are connecting with doesn't have permission - either because it doesn't exist, you have the wrong password, or you have no rights to connect from your IP to the target database.
In many cases, MySQL docker containers come configured to only allow connections to localhost (127.0.0.1) which means you must either (a) use port forwarding or (b) grant the user permission to connect from anywhere (i.e. %). Sometimes there is also a configuration switch that will automatically do this for you - read the documentation for your db container.
I have problem with mysql server. When I start MAMP Mysql server won't start. I tried to change port but it didn't help. I check the error log where I find this:

I hope someone can help me how to solve this problem.
I don't know if this will be your problem, but I tried killing mysqld with killall -9 mysqld and tried looking for mysqld running in Activity Monitor, but it wasn't there.
Eventually I worked it out: What had happened before the problem for me was that a mysqldump had been interrupted. That had corrupted a tablespace. So I quit and restarted MAMP PRO (servers are not set to auto start). Then changed my.cnf using MAMPs File > Edit template. And added the line innodb_force_recovery = 1. The servers started fine after that. I commented out that line after the fix.
Rename all files ib_logfileN (N being the number) from the MAMP/db/mysql56 folder.
mv tmp_ib_logfileN
Then restart MAMP.
Enjoyed
aI have the problem that both services won't start. On both, I get the Message
Error: MySQL shutdown unexpectedly. (The same with apache).
I already changed the ports of the apache server from 80 to 8080 and 443 to 4433, and also to others to check, that doesn't help.
I tried some solutions on similar posts here, like deleting the ibdata1-file in the mysql-folder, but none of these seem to work. I even don't think these might solve it, because both services are affected.
Another idea I had was that I had not enough rights on the pc to run these services, but I am logged in as administrator and I also have a postgres-service running which I am able to stop and restart.
I am using Windows 10, but had XAMPP running on it before.

httpd.exe: Syntax error on line 37 of E:/Data/Xampp/apache/conf/httpd.conf: ServerRoot must be a valid directory
The File errmsg.sys exists though.
I found another solution that worked for me!
If anyone has that problem, try to start apache via batch file "apache_start" located in xampp-directory. that gave me the error:
ServerRoot must be a valid directory
This again could be solved by running the "setup_xampp" batch file, located in the same directory. After completion, apache & mysql were running again.
I installed mysql thorugh source code .I followed all instruction from http://dev.mysql.com/doc/refman/5.5/en/installing-source-distribution.html
but after installation when i am trying to start mmysql server ,It is giving me below error:
[root#sumit bin]# ./mysqld_safe &
