This indicates that skip-innodb is enabled in the my.cnf file ..

ERROR 3 (HY000): Error writing file ‘/tmp/MY68ie0h’ (Errcode: 28)

this is due to a storage issue with the partition that is holding /tmp

You have two ways to fix this .

1) use a mysql_close() statement within your code. this is not needed for non-persistent connection per the PHP manual
PHP Manual

2) disallow persistent connection by turning it off within the php.ini file.

Persistent connection keeps the last connection active with mysql which goes into sleep mode.

Nice script to run via shell

I’ve small handy shell script that removes all tables without dropping and creating MySQL database again.

#!/bin/bash
MUSER="$1"
MPASS="$2"
MDB="$3"

# Detect paths

MYSQL=$(which mysql)
AWK=$(which awk)
GREP=$(which grep)

if [ $# -ne 3 ]
then
	echo "Usage: $0 {MySQL-User-Name} {MySQL-User-Password} {MySQL-Database-Name}"

	echo "Drops all tables from a MySQL"
	exit 1
fi

TABLES=$($MYSQL -u $MUSER -p$MPASS $MDB -e 'show tables' | $AWK '{ print $1}' | $GREP -v '^Tables' )

for t in $TABLES
do
	echo "Deleting $t table from $MDB database..."
	$MYSQL -u $MUSER -p$MPASS $MDB -e "drop table $t"

done

Fix

———–

you will need to edit the mysql config file

add skip-grant-tables under mysqld

/etc/my.cnf

then restart mysql

connect to the mysql db

issue the following command

UPDATE mysql.user SET Password=PASSWORD('new_pwd') WHERE User='admin';

then

FLUSH PRIVILEGES;

exit mysql ,

remove the skip-grant-tables from the mysqld config

restart mysql

*also very the password matches /etc/psa/.psa.shadow

cat /etc/psa/.psa.shadow

Reference

INSERT INTO reguser_active (test1, test2) values (”,”);

” tells mysql to insert a empty string into the column , you may also insert a
null value into the not null column as such

INSERT INTO reguser_active (test1, test2) values (‘null’,'null’);

and lastly you can modified your columns to allow null values.
