MySql version 5.7.12 getting crashed - mysql

We have migrated from SqlServer 2008 to MySql version 5.7.12 on AWS EC2 instance of Ubuntu 14.04 LTS Version. The server is getting crashed repeatedly. The logs are as below:

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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=52428800
read_buffer_size=20971520
max_used_connections=284
max_threads=214
thread_count=283
connection_count=283
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 8843311 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x7fe34c6be4d0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

07:08:48 UTC - mysqld got signal 11 ;
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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=52428800
read_buffer_size=20971520
max_used_connections=72
max_threads=214
thread_count=58
connection_count=58
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 8819493 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x7fe5f4402670
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
stack_bottom = 7fe6b1d60e40 thread_stack 0x40000
/usr/sbin/mysqld(my_print_stacktrace+0x2c)[0xebef8c]
/usr/sbin/mysqld(handle_fatal_signal+0x451)[0x7acb61]
/lib/x86_64-linux-gnu/libpthread.so.0(+0x10340)[0x7fe99f0de340]
Trying to get some variables.
Some pointers may be invalid and cause the dump to abort.
Query (7fe5f590f5c0): is an invalid pointer
Connection ID (thread ID): 102
Status: NOT_KILLED
Any pointers or help as to where we are going wrong will be greatly appreciated? Also, a small update, we had upgraded the MySql from 5.7.8 RC version? Can upgradtion also be an issue for error of this type to occur?

Your read_buffer_size of 20971520*max_threads means this one memory requirement is 4G of the 8,819,493 K bytes required. Tell us how much memory your machine has, please.
Since read_buffer_size serves scanning tables sequentially, a possible reasonable request would be read_buffer_size=1048576. A scan of 10M data would only require 10 reads.
If you could post show global variables and show global status, we could better assist.

The problem was resolved by setting of the variables in the my.cnf file. The variables were calculated with the help of My Sql Calculator with the help of which I was able to calculate the optimal amount of memory allocated for various purposes. One of the mistake that was done was that sort buffer size was set to 40 mb. That resulted is very less not of connections (< 270) while the DB system required about 1200 connections in total. That was a major relief. We had also given 15GB memory to the innodb_buffer_pool_size.
There was another issue with the slow running queries. In MS SQL, most of our select queries were run with(nolock) on tables. We had done that global level change through config by setting the configuration to read uncommited (default is repeatable read) that had boosted the performance of the queries significatly. (This may not be suitably desired for many others). But, for us it worked well.
Also, in the stored procedures, dropping the temporary tables did a reasonable work. Earlier, we were under wrong impression that as soon as the connection from the application is closed, the temporary table will be dropped which turned out to be false. So, we had manually dropped the temporary table created. (We were using temporary tables to emulate the functionality of rank, dense rank as in sql server). With this, we were able to convert the migration reasonably well.

How to access db [Error: ER_ACCESS_DENIED_ERROR: Access denied for user 'root'#'172.18.0.3' (using password: YES)] in docker container

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.

Can someone tell me what I am doing wrong? Or fix the code/stack I tried to run? I'm not an experienced user.
I had other installations of Wordpress in the past that I deleted and I am thinking that may be causing the conflicts... I don't know... I tried some diferences in the stack files that I searched the internet, renamed the containers, but I keep getting the same errors, and I am out of ideas.
Any solution will be appreciated. Thanks.
I'm running Open Media Vault > Docker > Portainer.
You are binding multiple volumes under same root of wordpress_multi_2.This is not a good way to mount volumes. Split them to separate folders (example for /wp and /db). And do not bind ports under 1024, as they are reserved, common convention for plaintext HTTP ports is like 8080 on development machines.
wordpress_multi_1:
...
ports:
- 8080:80
...
volumes:
- /srv/dev-disk-by-label-1TB/Config/wordpress_multi_1/wp:/var/www/html
db_multi_1:
...
volumes:
- /srv/dev-disk-by-label-1TB/Config/wordpress_multi_1/db:/var/lib/mysql
wordpress_multi_2: #2nd_instance
...
ports:
- 8081:80
...
volumes:
- /srv/dev-disk-by-label-1TB/Config/wordpress_multi_2/wp:/var/www/html
db_multi_2: #2nd_instance
...
volumes:
- /srv/dev-disk-by-label-1TB/Config/wordpress_multi_2/db:/var/lib/mysql
I finally got it to work!! And i even run a second Stack with a 3 and 4 installation just to check!
Following your advice, i changed the paths and the ports, and also added some things to the code, to be honest i´m not sure on what worked, but it´s working!
i added this:
links:
- db_multi_1
depends_on:
- db_multi_1
command: --default-authentication-plugin=mysql_native_password
One thing i noticed is that mysql container takes some minutes to fully start, only after that, the wordpress / MY-IP:8001 can work correctly.
Thanks for pointing me in the wright direction.

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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=8388608
read_buffer_size=65536
max_used_connections=48
max_threads=200
thread_count=7
connection_count=7
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 74620 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Ubuntu Server is randomly going down

I am having some trouble with my Digital Ocean's server which has a blog running on Wordpress.
Randomly the server goes on 100% memory/processing and over 200MB/s Disk IO until the blog crashes.
If I restart apache the server comes back to normal.
This is happening over three times a week and it has nothing to do with many users using the site at the same time.
I have browsed the internet and used some solutions and nothing has really helped.
I am using the following:
- Wordpress version: 4.7.2
- Php version:
PHP 5.6.28-1+deb.sury.org~xenial+1 (cli)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend Technologies
- Linux Version:
Linux 3.13.0-57-generic #95-Ubuntu SMP Fri Jun 19 09:28:15 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Ubuntu 16.04 server
I've spent some time looking on logfiles and the dmesg, fail2ban, faillog, and syslog does not have anything unusual.
However the apache error.log and access.log has some interesting things.
On the error log I've seen a lot of lines like these ones:
[Wed Oct 25 16:43:31.234364 2017] [:error] [pid 23211] [client 172.68.26.39:37081] PHP Warning: Error while sending QUERY packet. PID=23211 in public_html/wp-includes/wp-db.php on line 1877, referer: https://sitename/blogpostname/comment-page-6/

Went on the wp-db.php file on line 1877 and it is a random usual line on the file, nothing wrong with it.
After a google search I've seen a lot of people with the same problem changing some variables on the php and apache configuration files.
So I've increased the following variables:
max_execution_time
max_allowed_packet_size
max_user_connections
max_connections
And disabled the W3 Total Cache plugin
Still with no Luck.
Checked the cronjobs and it doesn't have any job which trigger at the same time that I had this problem.
I am putting the apache's error.log and access.log and mysql error.log on the above links, in case you need them.
Last time I had this issue was 25 OCT 16:40h until the restart of the apache service at 16:57h

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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 76382 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

innodb_print_all_deadlocks=1 # from OFF to record in error log for CORRECTION
slow_query_log=1 # from OFF to record for possible CORRECTION
innodb_log_buffer_size=838860800 REMOVE to allow default of 16M (buffer size is larger than file size today and likely your most significant difficulty) NOT a dynamic variable
thread_cache_size=100 #from 8 to support 500 created threads since start
innodb_read_ahead_threshold=8 #from 56 for your intensity of reading
innodb_stats_sample_pages=32 #from 8 for more accurate cardinality of ndx's
have_query_cache=NO #from yes default since you have no intention of using qc
query_cache_size=0 #from 16M to conserve RAM
key_buffer_size=1M #from 16M, only used by ISAM. Low requirements
key_cache_age_threshold=64800 #from 300 seconds, avoid RD for 8 hours
max_write_lock_count=128 #from enormous number to allow RD after this nn
sql_select_limit=1000000000 #from enormous number to 1 Billion rows selected limit
table_open_cache= 10000 #from 2000 to support 40,000 opened since start.
ulimit needs to be reviewed and made more tolerant, if possible.
When appropriate, provide feedback, please.
