MySQL Dump All Databases and Create (or Recreate) them on Import?
提问by Garrett
I was wondering how I can get the following file,
我想知道如何获得以下文件,
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 should recreate it (overwriting the old one).
在导入时自动创建任何尚未创建的数据库。此外,如果一个数据库已经存在,它应该重新创建它(覆盖旧的)。
Is this possible? Thanks!
这可能吗?谢谢!

Export: mysqldump -u root -p --all-databases > all_dbs.sql
Import: mysql -u root -p < all_dbs.sql

Export:
出口:
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:
查找 mysqldump 的文档。您可能想使用评论中提到的一些选项:
mysqldump -uroot -p --opt --all-databases > alldb.sql
mysqldump -uroot -p --all-databases --skip-lock-tables> alldb.sql
Import:
进口:
mysql -u root -p < alldb.sql
I Just found a new solution:
我刚刚找到了一个新的解决方案:
Create a bash script. It backs up each database into a different file
创建一个 bash 脚本。它将每个数据库备份到不同的文件中
#!/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.
不要使用“mysql”命令导出数据。请改用“mysqldump”。
