I am having mysql server in centos which is running fine, i recently got a script to dump all individual databases to one folder, when i run that script to dump, i'm getting this error when ever i run the script
mysqldump: Couldn't execute 'UNLOCK TABLES': MySQL server has gone away (2006)
Db_1
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (111) when trying to connect
DB2
i even have /var/lib/mysql/mysql.sock
in server, what is wrong, i even tried different scripts to execute my task every time i get the same problem,
but i can login using mysql -u root -p
i can dump using mysqldump -u root -p db_1 > db_1.sql
nothing creating problem, but only when i run through script it is creating problem
the script lines as follows,
databases=`$MYSQL --user=$MYSQL_ROOT_USER --password=$MYSQL_ROOT_PASSWORD -e "SHOW DATABASES;" | tr -d "| " | grep -v Database`
for db in $databases; do
echo $db
$MYSQLDUMP --force --opt --user=$MYSQL_ROOT_USER --password=$MYSQL_ROOT_PASSWORD --databases $db > "$OUTPUTDIR/$db.sql"
done
please suggest solutions.
