Magento 2 How to throw report error page (500 error) for testing purpose

 The goal is to get a report page for testing purpose 

So, we have to break magento somehow.

The fast way is:

1. pub/media is symlink to media folder

2. rename real media folder to media.bk

3. open PLP and enjoy the error

var/report will be:

Directory \"\/mnt\/data\/www\/project\/releases\/pub\/media\" cannot be created Warning!mkdir(): File exists" ...

Linux Bash check disk space

df --output=pcent / | tail -n +2 | tr -cd '0-9\n'

output available percent without header and symbol '%' - only number

#!/bin/bash

for mnt in / /var/log /var/www /mnt/shared; do

  chk_avail=`df --output=pcent $mnt | tail -n +2 | tr -cd '0-9\n'`

  flg=`echo $(( 100 - $chk_avail ))`

  if [ $flg -lt 15 ]; then

    echo 'Dataserver lack of free space, only '$flg' percent available in '$mnt' partition' | mail -s 'Dataserver lack of free space' alerts@gmail.com

  fi

done

Magento 2 Multistore one domain

domain.com/store1

domain.com/store2

1. Admin Panel: Stores/Settings/Stores (table store for checking code for MAGE_RUN_CODE)
   website: base, store: store1_code, store view: store1
   website: base, store: store2_code, store view: store2
2. Admin Panel: Configuration/Web/URL Options/Add Store Code to Urls - Yes

3. NGINX: 

   .php

       fastcgi_param  MAGE_RUN_TYPE    $MAGE_RUN_TYPE;

       fastcgi_param  MAGE_RUN_CODE    $MAGE_RUN_CODE;

   http

   map $request_uri $MAGE_RUN_CODE {

       ~^/store1 store1;

       ~^/store2 store2;

   }

   server
       set $MAGE_RUN_TYPE store;

find for time interval

 find . -maxdepth 1 -newermt '2019-01-01' ! -newermt '2021-02-15' -name "importexport_*" -exec ls -l '{}' \;

grep with wildcard

 If you have a file with data and you need only words which starts with ABCD- and three numbers at the end. You can use it

 egrep -ow ABCD-... the_file

-o, --only-matching

 -w, --word-regexp         force PATTERN to match only whole words

... - three any numbers
