mysql dumps from linux terminal in seperate files for each table - mysql

I am trying to take backups of the tables in a Database from linux terminal. I am using the following script to do it
GIT_MYSQL=/data/database/location to store
for T in `mysql -u [user] -h [Hostname] -p [database] -N -B -e 'show tables from database_name'`;
do
echo "Backing up $T"
mysqldump --skip-comments --compact -u [user] -p [password] [database] $T > $GIT_MYSQL/$T.sql
done;
I get the following error:
mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) when trying to connect
My mysql.sock is not present in the folder

You need the -h [Hostname] option to mysqldump, otherwise it will try to dump from a local database rather than the remote server that you got the list of tables from.
And to provide a password on the command line rather than prompting for it, you need to use --password=[password] or -p[password]; you can't have a space before the password.
mysqldump --skip-comments --compact -u [user] -h [Hostname] -p'[password]' [database] $T > $GIT_MYSQL/$T.sql

Making a copy of a existing database with out data in it

I want to copy a Database without copying its data, I mean I just want to copy the stucture and tables and foreign key and ... not the data in it.
The answer is here but I do not know where should I copy it ? In shell? In workbench? In query?
I entered it in query in workbenck and it has error !
Thank you in advance!
Edit
When I run it in my mysql shell I get this:
MySQL JS > mysqldump -u myusername -pmypassword -d olddb | mysql -u myusername -pmypassword -D newdb
SyntaxError: Unexpected identifier.
You'll need to run it on the command line for your OS (not the shell for MySQL as you tried earlier).
Under Linux (including Macs) it would look something like:
smm#smm-HP-ZBook-15-G2:~/$ mysqldump -u myusername -pmypassword -d olddb | mysql -u myusername -pmypassword -D newdb
Under Windows:
C:\> mysqldump -u myusername -pmypassword -d olddb | mysql -u myusername -pmypassword -D newdb
This is assuming mysqldump is in the PATH for your command line (it isn't if you get a command not found error). How to use a command line and set up the PATH depends on the OS and is beyond the scope of this answer.

MySQL 5.7 - Export Dump [duplicate]

I have a database that is quite large so I want to export it using Command Prompt but I don't know how to.
I am using WAMP.
First check if your command line recognizes mysql command. If not go to command & type in:
set path=c:\wamp\bin\mysql\mysql5.1.36\bin
Then use this command to export your database:
mysqldump -u YourUser -p YourDatabaseName > wantedsqlfile.sql
You will then be prompted for the database password.
This exports the database to the path you are currently in, while executing this command
Note: Here are some detailed instructions regarding both import and export
Simply use the following command,
For Export:
mysqldump -u [user] -p [db_name] | gzip > [filename_to_compress.sql.gz]
For Import:
gunzip < [compressed_filename.sql.gz] | mysql -u [user] -p[password] [databasename]
Note: There is no space between the keyword '-p' and your password.
Well you can use below command,
mysqldump --databases --user=root --password your_db_name > export_into_db.sql
and the generated file will be available in the same directory where you had ran this command.
You could find more on the official reference for mysqldump: Import Export MySQL DB
Note: use --databases instead of --database since the last one is no more supported.
Enjoy :)
First of all
open command prompt then open bin directory in cmd (i hope you're aware with cmd commands)
go to bin directory of your MySql folder in WAMP program files.
run command
mysqldump -u db_username -p database_name > path_where_to_save_sql_file
press enter system will export particular database and create sql file to the given location.
i hope you got it :)
if you have any question please let me know.
Go to command prompt at this path,
C:\Program Files (x86)\MySQL\MySQL Server 5.0\bin>
Then give this command to export your database (no space after -p)
mysqldump -u[username] -p[userpassword] yourdatabase > [filepath]wantedsqlfile.sql
Locate your mysql instance with:
which mysql
If this is correct then export with the following (else navigate to the mysql instance in your mamp folder in bin):
mysqldump -u [username] -p [password] [dbname] > filename.sql
And if you wish to zip it at the sametime:
mysqldump -u [username] -p [password] [db] | gzip > filename.sql.gz
You can then move this file between servers with:
scp user#xxx.xxx.xxx.xxx:/path_to_your_dump/filename.sql.gz your_detination_path/
(where xxx.xxx.xxx.xxx is the server IP address)
And then import it with:
gunzip filename.sql.gz | mysql -u [user] -p [password] [database]
To export PROCEDUREs, FUNCTIONs & TRIGGERs too, add --routines parameter:
mysqldump -u YourUser -p YourDatabaseName --routines > wantedsqlfile.sql
The problem with all these solutions (using the > redirector character) is that you write your dump from stdout which may break the encoding of some characters of your database.
If you have a character encoding issue. Such as :
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ...
then, you MUST use -r option to write the file.
MySQL
mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump.sql
Using Docker
docker exec --rm -v $pwd:dump -it mysql:5:7 mysqldump -u user -pyour-password-without-space-between-letter-p-and-your-password --default-character-set=utf8 --host $HOST database-name -r dump/dump.sql
Note: this mounts the current path as dump inside the instance.
We found the answer here
Conversely, don't use < to import your dump into your database, again, your non-utf8 characters may not be passed; but prefer source option.
mysql -u user -pYourPasswordYouNowKnowHow --default-character-set=utf8 your-database
mysql> SET names 'utf8'
mysql> SOURCE dump.sql
Give this command to export your database, this will include date as well
mysqldump -u[username] -p[userpassword] --databases yourdatabase | gzip > /home/pi/database_backup/database_`date '+%m-%d-%Y'`.sql.gz
(no space after -p)
I have installed my wamp server in D: drive so u have to go to the following path from ur command line->(and if u have installed ur wamp in c: drive then just replace the d: wtih c: here)
D:\>cd wamp
D:\wamp>cd bin
D:\wamp\bin>cd mysql
D:\wamp\bin\mysql>cd mysql5.5.8 (whatever ur verserion will be displayed here use keyboard Tab button and select the currently working mysql version on your server if you have more than one mysql versions)
D:\wamp\bin\mysql\mysql5.5.8>cd bin
D:\wamp\bin\mysql\mysql5.5.8\bin>mysqldump -u root -p password db_name > "d:\backupfile.sql"
here root is user of my phpmyadmin
password is the password for phpmyadmin so if u haven't set any password for root just nothing type at that place,
db_name is the database (for which database u r taking the backup)
,backupfile.sql is the file in which u want ur backup of ur database and u can also change the backup file location(d:\backupfile.sql) from to any other place on your computer
mysqldump -h [host] -p -u [user] [database name] > filename.sql
Example in localhost
mysqldump -h localhost -p -u root cookbook > cookbook.sql
mysqldump --no-tablespaces -u username -p pass database_name > db_backup_file.sql
Syntax
(mysqldump.exe full path) -u (user name) -p (password) (database name) > (export database file full path)
Example
c:>d:\wamp\bin\mysql\mysql5.6.12\bin\mysqldump.exe -u root -p mydbname > d:\mydb.sql
where d:\wamp\bin\mysql\mysql5.6.12\bin\mysqldump.exe will be your actual mysqldump.exe path, mydbname is the name of database which you want to export and d:\mydb.sql is the path where you want to store the exported database.
For import:
mysql -u db_username -p newFileName < databasName.sql
For export:
mysqldump -u db_username -p databasName > newFileName.sql
I have used wamp server. I tried on
c:\wamp\bin\mysql\mysql5.5.8\bin\mysqldump -uroot -p db_name > c:\somefolder\filename.sql
root is my username for mysql, and if you have any password specify it with:
-p[yourpassword]
Hope it works.
For windows OS :
When you get error 1064 mysql (42000) while trying to execute mysqldump command, exit from current terminal. And execute mysqldump command.
mysql>exit
c:\xampp\mysql\bin>mysqldump -uroot -p --databases [database_name] > name_for_export_db.sql
I was trying to take the dump of the db which was running on the docker and came up with the below command to achieve the same:
docker exec <container_id/name> /usr/bin/mysqldump -u <db_username> --password=<db_password> db_name > .sql
Hope this helps!
mysql -u -p databaseName>fileToPutDatabase
Login in your databse server and then hit the below command:-
mysql -u username -p databasename > exportfilename.sql
Then it will ask for password Enter the password and hit enter,it will take some time your database will be exported.
You can use this script to export or import any database from terminal
given at this link: https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh

Copy mysql database from remote server to local computer

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

mysqldump backup and restore to remote server

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
