Is it posible to duplicate an entire MySQL database on a linux server?
I know I can use export and import but the original database is >25MB so that's not ideal.
Is it possible using mysqldump or by directly duplicates the database files?
First create the duplicate database:
CREATE DATABASE duplicateddb;
Make sure the user and permissions are all in place and:
mysqldump -u admin -p originaldb | mysql -u backup -pPassword duplicateddb;
To remote server
mysqldump mydbname | ssh host2 "mysql mydbcopy"
To local server
mysqldump mydbname | mysql mydbcopy
I sometimes do a mysqldump and pipe the output into another mysql command to import it into a different database.
mysqldump --add-drop-table -u wordpress -p wordpress | mysql -u wordpress -p wordpress_backup
Create a mysqldump file in the system which has the datas and use pipe to give this mysqldump file as an input to the new system. The new system can be connected using ssh command.
mysqldump -u user -p'password' db-name | ssh user#some_far_place.com mysql -u user -p'password' db-name
no space between -p[password]
Making a Copy of a Database
# mysqldump -u root -p password db1 > dump.sql
# mysqladmin -u root -p password create db2
# mysql -u root -p password db2 < dump.sql
Here's a windows bat file I wrote which combines Vincent and Pauls suggestions. It prompts the user for source and destination names.
Just modify the variables at the top to set the proper paths to your executables / database ports.
:: Creates a copy of a database with a different name.
:: User is prompted for Src and destination name.
:: Fair Warning: passwords are passed in on the cmd line, modify the script with -p instead if security is an issue.
:: Uncomment the rem'd out lines if you want script to prompt for database username, password, etc.

SUCCESSFUL!!!
This won't work for InnoDB.
Use this workaround only if you are trying to copy MyISAM databases.
If locking the tables during backup, and, possibly, pausing MySQL during the database import is acceptable, mysqlhotcopy may work faster.
E.g.
Backup:
# mysqlhotcopy -u root -p password db_name /path/to/backup/directory
Restore:
cp /path/to/backup/directory/* /var/lib/mysql/db_name
mysqlhotcopy can also transfer files over SSH (scp), and, possibly, straight into the duplicate database directory.
E.g.
# mysqlhotcopy -u root -p password db_name /var/lib/mysql/duplicate_db_name
This worked for me with command prompt, from OUTSIDE mysql shell:
# mysqldump -u root -p password db1 > dump.sql
# mysqladmin -u root -p password create db2
# mysql -u root -p password db2 < dump.sql
This looks for me the best way. If zipping "dump.sql" you can symply store it as a compressed backup. Cool! For a 1GB database with Innodb tables, about a minute to create "dump.sql", and about three minutes to dump data into the new DB db2.
Straight copying the hole db directory (mysql/data/db1) didn't work for me, I guess because of the InnoDB tables.
For me the following lines of code did the trick
mysqldump --quote-names -q -u username1 --password='password1' originalDB | mysql -u username2 --password='password2' duplicateDB
Once upon a time in MySQL you could just copy all the table files to another directory in the mysql tree
mysql cli - create database db2
linux cli - cp db1 db2

Hi i would like to import a large mysql dump file into localhost maria db...but found this error
my command is just like so
mysql -u root -p dbname < dumpfile.sql
$ mysql --help | grep user
-u, --user=name User for login if not current user.
So try mysql -uroot -p dbname < dumpfile.sql (your screenshot doesn't use -u)
I want to backup all privileges related to specific user (for example u_1) from a MySQL database and restore that in another server. As described here, The 'mysql' database contains users/privileges/passwords. So I have to backup all related data from all tables of mysql database (mysql.user,mysql.db, ...). I can run this command:
$ mysqldump -u root --flush-privileges -r mysql.sql -p mysql
But of course the mysql.sql contains all users and all privileges.
Also I tried this command:
$ mysqldump -u root -p --where="user.user='u_1'" mysql user> mysql.sql
But as expected, it only contains a row of mysql.user table.
Is there a way to strip out other users except of u_1?
Try these options (line breaks for clarity):
$ mysqldump -u root -p
--where="user='u_1'"
--complete-insert
--extended-insert
--no-create-info
mysql
user db tables_priv columns_priv procs_priv proxies_priv
> mysql.sql
Or... let's call the above solution "the hard way."
This should be the easy way:
$ mysql -u root -p
--skip-column-names
-e "SHOW GRANTS FOR 'u_1';"
> grants.sql
I would use:
pt-show-grants --only u_1
pt-show-grants is a tool in the free Percona Toolkit.
See https://www.percona.com/doc/percona-toolkit/LATEST/pt-show-grants.html
I know how mysqldump works.
But dont know where to use it?
If I execute this command after starting mysql program then it says error.
I am using ubuntu. So how can I use this utility?
Backup your database this way too..
mysql -u root -p DB_NAME > db_name_backup.sql
If you want to backup all database simply run this
mysql -u root -p > mysql_db_backup.sql
You will learn more about mysql and mysqldump here..

mysqldump and mysql
MySQL Database Backup using mysqldump
shell> mysqldump --opt db_name > backup-file.sql
You can read the dump file back into the server like this:
shell> mysql db_name < backup-file.sql
Or like this:
shell> mysql -e "source /path-to-backup/backup-file.sql" db_name
mysqldump is also very useful for populating databases by copying data
from one MySQL server to another:
shell> mysqldump --opt db_name | mysql --host=remote_host -C db_name
It is possible to dump several databases with one command:
shell> mysqldump --databases db_name1 [db_name2 ...] > my_databases.sql
If you want to dump all databases, use the --all-databases option:
shell> mysqldump --all-databases > all_databases.sql
If tables are stored in the InnoDB storage engine, mysqldump provides a
way of making an online backup of these (see command below). This
backup just needs to acquire a global read lock on all tables (using
FLUSH TABLES WITH READ LOCK) at the beginning of the dump. As soon as
this lock has been acquired, the binary log coordinates are read and
lock is released. So if and only if one long updating statement is
running when the FLUSH... is issued, the MySQL server may get stalled
until that long statement finishes, and then the dump becomes
lock-free. So if the MySQL server receives only short (in the sense of
"short execution time") updating statements, even if there are plenty
of them, the initial lock period should not be noticeable.
shell> mysqldump --all-databases --single-transaction > all_databases.sql
For point-in-time recovery (also known as “roll-forward”, when you need
to restore an old backup and replay the changes which happened since
that backup), it is often useful to rotate the binary log (see
Section 8.4, “The Binary Log”) or at least know the binary log
coordinates to which the dump corresponds:
shell> mysqldump --all-databases --master-data=2 > all_databases.sql
or
shell> mysqldump --all-databases --flush-logs --master-data=2 > all_databases.sql
The simultaneous use of --master-data and --single-transaction works as
of MySQL 4.1.8. It provides a convenient way to make an online backup
suitable for point-in-time recovery if tables are stored in the InnoDB
storage engine.
For more information on making backups, see Section 6.1, “Database
Backups”.
mysqldump -u MYSQL_USER -h MYSQL_SERVER -pMYSQL_PASS --all-databases > "dbs.sql"
You use it directly on the terminal, just like mysql it self, and pass the parameters directly to it.
mysqldump -u [user] -p[password] [database name] > dumpfilename.sql
yes you can.
see http://dev.mysql.com/doc/refman/5.0/en/mysqldump.html for more information on the tool.
If it's an entire DB, then:
$ mysqldump -u [uname] -p[pass] db_name > db_backup.sql
If it's all DBs, then:
$ mysqldump -u [uname] -p[pass] --all-databases > all_db_backup.sql
If it's specific tables within a DB, then:
$ mysqldump -u [uname] -p[pass] db_name table1 table2 >
table_backup.sql
You can even go as far as auto-compressing the output using gzip (if your DB is very big):
$ mysqldump -u [uname] -p[pass] db_name | gzip > db_backup.sql.gz
If you want to do this remotely and you have the access to the server in question, then the following would work (presuming the MySQL server is on port 3306):
$ mysqldump -P 3306 -h [ip_address] -u [uname] -p[pass] db_name >
db_backup.sql
To IMPORT:
ype the following command to import sql data file:
$ mysql -u username -p -h localhost DATA-BASE-NAME < data.sql
In this example, import 'data.sql' file into 'blog' database using vivek as username:
$ mysql -u sat -p -h localhost blog < data.sql
If you have a dedicated database server, replace localhost hostname with with actual server name or IP address as follows:
$ mysql -u username -p -h 202.54.1.10 databasename < data.sql
OR use hostname such as mysql.cyberciti.biz
$ mysql -u username -p -h mysql.cyberciti.biz database-name < data.sql
If you do not know the database name or database name is included in sql dump you can try out something as follows:
$ mysql -u username -p -h 202.54.1.10 < data.sql
REfer: http://dev.mysql.com/doc/refman/5.6/en/mysqldump.html
I'm under VPN and I don't have SSH access to remote server.
I can connect to remote database by console
mysql -u username -p -h remote.site.com
Now I'm trying to clone the remote database to local computer
mysqldump -u username -p -h remote.site.com mysqldump | mysql -u root -ppassword webstuff
And I've got error
mysqldump: Got error: 1045: Access denied for user 'webstaff'#'10.75.1.2'
(using password: YES) when trying to connect
How to copy mysql database from remote server to local computer?
Assuming the following command works successfully:
mysql -u username -p -h remote.site.com
The syntax for mysqldump is identical, and outputs the database dump to stdout. Redirect the output to a local file on the computer:
mysqldump -u username -p -h remote.site.com DBNAME > backup.sql
Replace DBNAME with the name of the database you'd like to download to your computer.
Check syntax and execute one command at a time, then verify output.
mysqldump -u remoteusername -p remotepassword -h your.site.com databasename > dump.sql
mysql -u localusername -p localpassword databasename < dump.sql
Once you've matched all passwords, you can use pipe.
Often our databases are really big and the take time to take dump directly from remote machine to other machine as our friends other have suggested above.
In such cases what you can do is to take the dump on remote machine using MYSQLDUMP Command
MYSQLDUMP -uuser -p --all-databases > file_name.sql
and than transfer that file from remote server to your machine using Linux SCP Command
scp user#remote_ip:~/mysql_dump_file_name.sql ./
This can have different reasons like:
You are using an incorrect password
The MySQL server got an error when trying to resolve the IP address of the client host to a name
No privileges are granted to the user
You can try one of the following steps:
To reset the password for the remote user by:
SET PASSWORD FOR some_user#ip_addr_of_remote_client=PASSWORD('some_password');
To grant access to the user by:
GRANT SELECT, INSERT, UPDATE, DELETE, LOCK TABLES ON YourDB.* TO user#Host IDENTIFIED by 'password';
Hope this helps you, if not then you will have to go through the documentation

Copy mysql database from remote server to local computer
I ran into the same problem. And I could not get it done with the other answers. So here is how I finally did it (yes, a beginner tutorial):
Step 1: Create a new database in your local phpmyadmin.
Step 2: Dump the database on the remote server into a sql file (here I used Putty/SSH):
mysqldump --host="mysql5.domain.com" --user="db231231" --password="DBPASSWORD" databasename > dbdump.sql
Step 3: Download the dbdump.sql file via FTP client (should be located in the root folder)
Step 4: Move the sql file to the folder of your localhost installation, where mysql.exe is located. I am using uniform-server, this would be at C:\uniserver\core\mysql\bin\, with XAMPP it would be C:\xampp\mysql\bin
Step 5: Execute the mysql.exe as follows:
mysql.exe -u root -pYOURPASSWORD YOURLOCALDBNAME < dbdump.sql
Step 6: Wait... depending on the file size. You can check the progress in phpmyadmin, seeing newly created tables.
Step 7: Done. Go to your local phpmyadmin to check if the database has been filled with the entire data.
Hope that helps. Good luck!
Note 1: When starting the uniformer-server you can specify a password for mysql. This is the one you have to use above for YOURPASSWORD.
Note 2: If the login does not work and you run into password problems, check your password if it contains special characters like !. If so, then you probably need to escape them \!.
Note 3: In case not all mysql data can be found in the local db after the import, it could be that there is a problem with the mysql directives of your dbdump.sql
Better yet use a oneliner:
Dump remoteDB to localDB:
mysqldump -uroot -pMypsw -h remoteHost remoteDB | mysql -u root -pMypsw localDB
Dump localDB to remoteDB:
mysqldump -uroot -pmyPsw localDB | mysql -uroot -pMypsw -h remoteHost remoteDB
C:\Users\>mysqldump -u root -p -h ip address --databases database_name -r sql_file.sql
Enter password: your_password
This answer is not remote server but local server. The logic should be the same. To copy and backup my local machine MAMP database to my local desktop machine folder, go to console then
mysqldump -h YourHostName -u YourUserNameHere -p YourDataBaseNameHere > DestinationPath/xxxwhatever.sql
In my case YourHostName was localhost. DestinationPath is the path to the download; you can drag and drop your desired destination folder and it will paste the path in.
Then password may be asked:
Enter password: xxxxxxxx
How can i use mysqldump to backup and restore database to a remote server?
Both have root access. I am using putty to perform this.
So far I tried the following:
mysqldump -u root -p >z*x311a!# masdagn_joom15 | mysql \ -u root -p g2154hE6-AsXP --host=207.210.71.26 -C masdagn_joom15temp \g
but it refused
the local password is: >z*x311a!#
the remote password is: g2154hE6-AsXP
This link provides information on backing up and restoring with mysqldump. It also gives some examples with a remote server.
The important commands from that link being:
backup:
mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
restore:
mysql -u root -p[root_password] [database_name] < dumpfilename.sql
[local-server]# mysqldump -u root -prootpswd db | mysql \
-u root -ptmppassword --host=remote-server -C db1
[Note: There are two -- (hyphen) in front of host]
Please note that you should first create the db1 database on the remote-server before executing the following command.
mysqldump --user=username --password=pwd db_name | bzip2 -c > /backup_dir/db_name.sql.bz2
you can embed this part in a script, afterward you can use FTP to transfer to the other location.
To restore, you can
bzip2 -d db_name.sql.bz2
mysql --user=username --password=pwd db_name < db_name.sql
Your local password contains the > character, which is interpreted as a redirect character by most shells. As a general rule, it will make your life considerably easier if you keep your MySQL passwords alphanumeric [A-Za-z0-9]. And it will make your system more secure if you avoid publicly posting your passwords.
here is what I do for a quick dump to another remote server...
assuming that you have setup an ssh key between the 2 servers
create file dump-to-server.sh
chmod to executable (chmod 0755 dump-to-server.sh)
run your sync ./dump-to-server.sh schema_name root#remote.server.net
dump-to-server.sh
\#!/bin/bash
if [[ -z "$1" || -z "$2" ]]; then
echo "--------- usage ---------";
echo "./dump-to-server.sh schema_name root#remote.server.net";
echo "";
else
mysqldump --opt "$1" | gzip -c | ssh "$2" "gunzip -c | mysql $1"
fi
For a single DB, Taking backup from a remote server is :
mysqldump -u<user> -p<pwd> -h<remote-host> [database-name] > dump.sql
Restore is:
mysql -u<user> -p<pwd> -h<remote-host> [database-name] < dump.sql
more details about options of mysqldump are available here:
