There are a little different to do this on Windows.
Create a bat file, contains mysql database backup command text.
Create a task in Windows Task Schedule to execute this bat file.
Then you could config this task as your wish, and do restore.
1: Backup Database.
#ECHO OFF
set filename=%date:~0,4%%date:~5,2%%date:~8,2%%time:~0,2%%time:~3,2%%time:~6,2%
"C:\Program Files\MySQL\MySQL Server 5.7\bin\mysqldump.exe" -uroot -p123456 -hlocalhost databaseName > C:\Danny\MySql-BackUp\databaseName-%filename%.sql
Format Explain:
mysqldump.exe –e –u[username] -p[password] -h[hostname] [database name] > C:[filename].sql
Run batch file, you will get a sql file contains all database info.
2:Restore database using backup sql.
Get into Mysql root path in CMD, and execute below command:
C:\Program Files\MySQL\MySQL Server 5.7\bin>mysql.exe -uroot -p123456 -hlocalhost databaseName < C:\Danny\MySql-BackUp\databaseName-201801311848321.sql

Some one please correct the below syntax to restore the mysql backup file using
command prompt.
"C:\MySQL\MySQL Server 5.7\bin\mysql.exe" -u root -pmypassword source C:/Program Files/Default Company Name/Setup2/Dump20160805.sql
"C:\MySQL\MySQL Server 5.7\bin\mysqldump.exe" -uroot -pmypassword > C:/Program Files/Default Company Name/Setup2/Dump20160805.sql
I am working on Linux (Ubuntu), and I want to export the whole schema from .sh file to .sql in order to open it in MySQL Workbench - but how can I do it?
I have tried with mysqldump but it doesn't work, I wrote this command after opening .sh database, but I am not sure if it has some influence.
Command line in terminal:
mysql> mysqldump -uuser -ppassword db > db.sql
And it doesn't work - MySQL syntax error displays after that
Here .sh means a script file extension in which you will write your commands and .sql means a backup/dump file.
Example
Execute below command on linux prompt-
sudo vi backup_script.sh
It will open a blank file you can write your script here like -
cd /root/backup/
mysqldump -uroot -proot123 mydb > /root/backup/mydb.sql
Now save this file by Esc + : + wq
Note: backup folder should exist in root else you can create by below command-
mkdir /root/backup
Now you can execute backup_script.sh by below command-
sh backup_script.sh
It wil take your mydb database backup at /root/backup/ path.
1.Install mysql-client which includes mysqldump
user#local:~$ sudo apt-get install mysql-client-5.1
2. backup database
user#local:~$ mysqldump -u root -p[root_password] [database_name] > dumpfilename.sql
3. if you need you can import
user#local:~$ mysql -u root -p[root_password] [database_name] < dumpfilename.sql
Is there any way to copy all the Database - Tables,Stored Procedures
into a file and save on a flash disk?
I want to be able to open it from anywhere.
Also is there anyway that I can pass the permission while I do so?
If you have mySql database with name "mydatabase" to backup you have to execute following code from a command line:
mysqldump -u root -p mydatabase > mydatabase.sql
and after that put your password
To restore it on another server, copy mydatabase.sql and execute from the command line:
mysql -u root -p mydatabase < mydatabase.sql
I have copy of .sql file that contains large data. I saved it from phpmyadmin while I was using WAMP for development. Now I am working with CentOS, and I have transferred the data to my VirtualBox running CentOs already.
So, the problem is not about transferring the file but running the .sql file using shell, so the data can be transferred to the new mysql server.
Does anyone know any commands?
Initially I thought moving this entire directory:
C:\wamp\bin\mysql\mysql5.5.24\data
To my new server environment would be a good idea, but I can't seem to find where the data folder is kepyt in centos-mysql.
whereis mysql gives mysql: /usr/bin/mysql /usr/lib/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz
I have checked all this folders to find the data folder but to no avail.
if you created the .sql file with mysqldump or if it is otherwise a legal mysql script containing sql commands you can simply pipe this contents to your centOs mysql instance:
$ mysql -uroot -p dbname < dump.sql
where dbname is the name of your database and dump.sql your .sql file.
Follow these steps:
1- In your Windows Environment, from command line(CMD), go to the folder:
cd "C:\wamp\bin\mysql\mysql5.5.24\bin
2- Run: mysqldump -uroot -pYourPassword DataBaseName > myBackup.sql
3- On your centOs machine, open a terminal:
mysql -uroot -p
4- In mysql console:
create database DataBaseName;
exit;
5- Transfer the myBackup from your Windows System, to centOS, open a terminal in
the same directory where myBackup.sql lives:
mysql -uroot -p DataBaseName < myBackup.sql
I want to copy my mysql database from my computer to another computer. How can I do this?
How to copy Mysql database from one Computer to another / backup database using mysqldump
We can transfer a MySQL database from one PC to another PC using
mysqldump command.
We have to create dump file of database to transfer database from
one PC to another PC.
MySQL database is not portable database i.e. we cannot transfer it
from one PC to another PC by copying and pasting it.
We can use following method to transfer database.
Creating a dumpfile from database/ Taking backup of MySQL database:
Open command prompt.
Execute following commands to change directory
>c: “press enter”
>cd program files/MySQL/MySQL Server 5.1/ bin “press enter”
>mysqldump -u root -p database_name > database_name.sql “press enter”
Enter password: password of MySQL
Copy sql file and paste it in PC where you want to transfer database.
2. Dumping sql file into database:-
- Open MySQL command line client command prompt.
- Execute following command to create database.
create database database_name;
“press enter” Database name is must as that of your database_name.
Copy that sql file into location “c:/program files/MySQL/MySQL Server 5.1/bin”
*- Now open command prompt and execute following commands.*
>C: “press enter”
>cd program files/MySQL/MySQL Server5.1/bin “press enter”
>mysql –u root –p database_name < database_name.sql “press enter”
Your database is created on PC.
Now in MySQL command prompt check your database.

This best and the easy way is to use a db tools(SQLyog)
http://www.webyog.com/product/downloads
With this tools you can connect the 2 databases servers and just copy one database on server a to server b.

For a database named "lbry", try this:
mysqldump -u root -p lbry > dump-lbry.sql
Create a database of the same name ("lbry" in this example) on the computer to which you wish to copy the database contents
Then import it:
mysql -u root -p lbry < dump-lbry.sql
You can do by this process step-by-step using MySQL WorkBench.
Install MySQL Workbench
Connect to existing Database
Go to Navigator -> Management -> Data Export.
(this will dump queries of tables one by one in a separate folder, Workbench uses the same folder to import)
Create Database on target PC.
Connect to Target Database (would consist of 0 tables in DB)
Go to Navigator -> Management -> Data Import/Restore.
(this will use the dump folder and create tables in your target Database).
Hope this helps.
The only SAFE way to copy databases from one machine to another is to first quiesce the database (make sure no clients are modifying it), then use the mysqldump command to create a text representation of your schema and the contents of your tables. Then copy that text file over to the other machine and read it in by specifying it as the input to the mysql command.
Attempting to copy the actual mysql data directories over is asking for trouble, since they are dependent on the architecture of the machine that mysql is running on and likely on the version of mysql and whatever storage engine is in use.
This tutorial is in Ubuntu but will work on Redhat, Centos, Fedora, Suse
We can dump database, transfer it to another server, and restore it
It will show how to take care of things like modified credentials as a result and moving debain.cnf file
4 dump restore will slow down the serverHow it works
4.1 Run mysqldump on source server:this builds a MySQL executable script for the destination server.
During this time the MySQL server will queue queries
4.2 Copy dump file to the destination server
4.3 Empty destination server
4.4 Execute dump file on the destintion server
Server A(Source Server)
Server B (Destination Server)
Case 1:Server A
root#source$ mysql --defaults-file=/etc/mysql/debain.cnf
mysql>show databases;
mysql>use testdb;(The database to dump)
mysql>show tables;(To Check the tables)
mysql>^c
-- now dump the databses
root#surce$ mysql --defaults-file=/etc/mysql/debain.cnf --all-databses | gzip -c > dump.sql.gz
root#surce$ gzip -dc dump.sql.gz
To copy the files create a ssh key on the source server
root#surce$ ssh-keygen
root#surce$ cat /root/.ssh/id_rsa.pub
select and copy all the ssh key string
root#surce$ scp dump.sql.gz ubuntu#destination:
goto destination server
last step copy the contents of debain.cnf file
root#surce$ cat /etc/mysql/debain.cnf
[client]
host = localhost
user = debain-sys-maint
password = mysecret
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = debain-sys-maint
password = mysecret
socket = /var/run/mysqld/mysqld.sock
basedir = /usr
select all and copy this file to detination server.
Note: The sockey path can be different in your machine .use locate command to find the exact path
Case 2. Server B
drop all databses
root#destination$ echo show databases | mysql --defaults-file=/etc/mysql/debian.cnf --skip-column-names | awk '{print "drop database "$1";"}'
if this command doesnot drop databses use it with -force option
root#destination$ echo show databases | mysql --defaults-file=/etc/mysql/debian.cnf --skip-column-names | awk '{print "drop database "$1";"}' | mysql --defaults-file=/etc/mysql/debian.cnf -f
copy the ssh key on the destination server
root#destination$ echo "paste the key here" >> /home/ubuntu/.ssh/authorised_keys
goto source Server and use scp command to move the dump on the destination server
(inject the file)
root#destination$ gzip -dc /home/ubuntu/dump.sql.gz | mysql --defaults-file=/etc/mysql/debain.cnf
root#destination$ > /etc/mysql/debain.cnf
root#destination$ nano /etc/mysql/debain.cnf
paste the contents of .cnf file from source server here and save the file
:x
root#destination$ mysql --defaults-file= /etc/mysql/debain.cnf
if you get the mysql prompt then everything should be working file

I was able to restore a backup that was shared with me following this thread, specifically #jmail's answer, but, I thought that I could provide a bit more concise answer for future users. I received a dump file with a .sql extension, not a .dump extension as I would have expected.
I tried to place it in my project folder and restore it but I got error 22, referring to access privileges. I moved it to “c:/program files/MySQL/MySQL Server 5.1/bin” and then ran it by:
1) Starting MySQL in the command prompt.
2) Creating the new database that I wanted to restore to
3) Switching to the database
USE new_DB;
4) Running
source c:/program files/MySQL/MySQL Server 5.1/bin/backup.sql
I'm not sure how the backup.sql file was created but this worked for restoring it on my Windows 10 system.
mysqldump --databases dbname -hsource_server_ip -usource_server_userName -psource_server_passcode | mysql
-udest_server_user_name -pdest_server_user_passcode &
There are three general ways to invoke mysqldump:
shell> mysqldump [options] db_name [tbl_name ...]
shell> mysqldump [options] --databases db_name ...
shell> mysqldump [options] --all-databases
If you do not name any tables following db_name or if you use the --databases or --all-databases option, entire databases are dumped.
mysqldump does not dump the INFORMATION_SCHEMA database by default. MariaDB dumps the INFORMATION_SCHEMA if you name it explicitly on the command line, although currently you must also use the --skip-lock-tables option.
To see a list of the options your version of mysqldump supports, execute mysqldump --help.
I just summarize jmail's answer:
Database to SQL file at computer 1:
mysqldump --user <user name> --password <database> > <output file> for example mysqldump --user root --password movie > movie.sql
SQL file to database at computer 2:
mysql --user <user name> --password <database> < <output file> for example mysql --user root --password movie < movie.sql
