MySQL Dump All Databases and Create (or Recreate) them on Import?
I was wondering how I can get the following file,
mysqldump -h server -u root -p --all-databases > all_dbs.sql
to automatically create any databases that are not yet created, when imported. Also, if a database is already present, it 开发者_StackOverflowshould recreate it (overwriting the old one).
Is this possible? Thanks!
Export: mysqldump -u root -p --all-databases > all_dbs.sql
Import: mysql -u root -p < all_dbs.sql
Export:
mysqldump -uroot -p --all-databases > alldb.sql
Look up the documentation for mysqldump. You may want to use some of the options mentioned in comments:
mysqldump -uroot -p --opt --all-databases > alldb.sql
mysqldump -uroot -p --all-databases --skip-lock-tables> alldb.sql
Import:
mysql -u root -p < alldb.sql
I Just found a new solution:
Create a bash script. It backs up each database into a different file
#!/bin/bash
USER="zend"
PASSWORD=""
#OUTPUT="/Users/rabino/DBs"
#rm "$OUTPUTDIR/*gz" > /dev/null 2>&1
databases=`mysql -u $USER -p$PASSWORD -e "SHOW DATABASES;" | tr -d "| " | grep -v Database`
for db in $databases; do
if [[ "$db" != "information_schema" ]] && [[ "$db" != "performance_schema" ]] && [[ "$db" != "mysql" ]] && [[ "$db" != _* ]] ; then
echo "Dumping database: $db"
mysqldump -u $USER -p$PASSWORD --databases $db > `date +%Y%m%d`.$db.sql
# gzip $OUTPUT/`date +%Y%m%d`.$db.sql
fi
done
do not use "mysql" command to export data. Please use "mysqldump" instead.
I have to administrate a server that saves only:
\n
Exiting...
after executing "mysql --user=username --password=passord > somefile.sql"
/applications/MAMP/library/bin/mysqldump -u root -p --all-databases > all_dbs.sql
