How can I do a mysqldump from a server by using the Terminal?
I did the following:
First of all I logged in:
ssh root#123.456.78.90 // then I enter my password
then I do:
mysql->show databases;
after that:
use the_database;
then I do:
mysqldump -u myusername -p the_database > db_backup.sql
after that, obviously, nothing happens and I do not get an error. So my question is, where does it save the backup and how can I get a the mysqldump on my local machine?
There are multiple ways of how and where to backup, but most probably you would not like to store your backup in the same server where you are running the database.
If you have ssh access to the server you could create an ssh-tunnel, the most basic example of this could be:
$ ssh -L 3307:localhost:3306 root#123.456.78.90
What this will do is to open port 3307 locally (just in case you already are using 3306) and forward it to localhost:3306 going through 123.456.78.90
Then you could do something like:
$ mysqldump -h localhost -P 3307 -u myusername -p the_database > db_backup.sql
To know your current path, run pwd it will print your current directory and in where the db_backup.sql will be created in case you don't specify and absolute path.
Without using ssh you could also try to connect directly by just specifying the host:
$ mysqldump -h 123.456.78.90 -u myusername -p the_database > db_backup.sql
In case the port is open probably you will need just to modify/grant the user permissions to allow your IP to access:
mysql> GRANT ALL ON the_database.* TO your_user#'123.456.78.90' IDENTIFIED BY 'secret';
Connect to your server using ssh command.
run below code
mysqldump -u userName -p databaseName > /path/to/backup.sql
the location path must be on same server
Hi when I try to connect remote mysql
mysql -u root -p xxxx -h xxxx -P 80
mysql: [Warning] Using a password on the command line interface can be insecure.
then I hang at here
Does anyone knows how to slove this
In your command you are specifyng port 80. By default MySQL works on port 3306.
I am running the following command as given on web to connect the mysql data base but it gives syntax error new line expected here is the command i am entering.
mysql -<hivelettest.c0e9graawyhr.us-west-2.rds.amazonaws.com -p 3306 -u <user> -p <pass>
The <> parts of the command were given to show where the username and password should go. They shouldn't be in the command:
mysql -hmydbserver.co.uk -P3306 -u username -pmypassword
Try this, and make sure that there is no space between -u or -p. And if you are using PORT you need to write it differently. The password parameter must then be --password=
mysql -hmydbserver.co.uk -P 3306 -uUsername --password=yourpassword
Since 3306 is the standard one you could leave it out, then you can write it like this.
mysql -hmydbserver.co.uk -uUsername -pYourpassword
If you want to pass with a command, do it like this.
mysql -hmydbserver.co.uk -P 3306 -uUsername --password=yourpassword nameofdatabase
-e "SELECT * FROM tablename"
I have a server with Rackspace. I want to access the database from my local machine command line.
I tried like:
mysql -u username -h my.application.com -ppassword
But it gives an error:
ERROR 2003 (HY000):
Can't connect to MySQL server on 'my.application.com' (10061)
What causes this error and how can I connect to the remote database?
To directly login to a remote mysql console, use the below command:
mysql -u {username} -p'{password}' \
-h {remote server ip or name} -P {port} \
-D {DB name}
For example
mysql -u root -p'root' \
-h 127.0.0.1 -P 3306 \
-D local
no space after -p as specified in the Using Options on the Command Line documentation
It will take you to the mysql console directly by switching to the mentioned database.
simply put this on terminal at ubuntu:
mysql -u username -h host -p
Now hit enter
terminal will ask you password, enter the password and you are into database server
edit my.cnf file:
vi /etc/my.cnf:
make sure that:
bind-address=YOUR-SERVER-IP
and if you have the line:
skip-networking
make sure to comment it:
#skip-networking
don't forget to restart:
/etc/init.d/mysqld restart
For Mac, use the following command:
mysql -u app -h hostaddress -P port -D dbname -p
and then enter the password when prompted.
If you want to not use ssh tunnel, in my.cnf or mysqld.cnf you must change 127.0.0.1 with your local ip address (192.168.1.100) in order to have access over the Lan. example bellow:
sudo nano /etc/mysql/mysql.conf.d/mysqld.cnf
Search for bind-address in my.cnf or mysqld.cnf
bind-address = 127.0.0.1
and change 127.0.0.1 to 192.168.1.100 ( local ip address )
bind-address = 192.168.1.100
To apply the change you made, must restart mysql server using next command.
sudo /etc/init.d/mysql restart
Modify user root for lan acces ( run the query's bellow in remote server that you want to have access )
root#192.168.1.100:~$ mysql -u root -p
..
CREATE USER 'root'#'%' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
If you want to have access only from specific ip address , change 'root'#'%' to 'root'#'( ip address or hostname)'
CREATE USER 'root'#'192.168.1.100' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'root'#'192.168.1.100' WITH GRANT OPTION;
FLUSH PRIVILEGES;
Then you can connect:
nobus#xray:~$ mysql -h 192.168.1.100 -u root -p
tested on ubuntu 18.04 server
Try this command mysql -uuser -hhostname -PPORT -ppassword.
I faced a similar situation and later when mysql port for host was entered with the command, it was solved.
try telnet 3306. If it doesn't open connection, either there is a firewall setting or the server isn't listening (or doesn't work).
run netstat -an on server to see if server is up.
It's possible that you don't allow remote connections.

How Do I Enable Remote Access To MySQL Database Server?
I assume you have MySQL installed on your machine. Execute the command below after filling missing details:
mysql -uUSERNAME -pPASSWORD -hHOSTNAME -P3306
mysql servers are usually configured to listen only to localhost (127.0.0.1), where they are used by web applications.
If that is your case but you have SSH access to your server, you can create an ssh tunnel and connect through that.
On your local machine, create the tunnel.
ssh -L 3307:127.0.0.1:3306 -N $user#$remote_host
(this example uses local port 3307, in case you also have mysql running on your local machine and using the standard port 3306)
Now you should be ale to connect with
mysql -u $user -p -h 127.0.0.1 -P 3307
There is simple command.
mysql -h {hostip} -P {port} -u {username} -p {database}
Example
mysql -h 192.16.16.2 -P 45012 -u rockbook -p rockbookdb
you can use the following code to connect to a remote MY SQL database
mysql -u {database_user} -p{db_password} -h {host_name} -P {port_number}
mysql -u admin -p'your_password' -h your-company.aws.com -P 3306
Must check whether incoming access to port 3306 is block or not by the firewall.
this solution worked for me:
On your remote machine (example: 295.13.12.53) has access to your target remote machine (which runs mysql server)
ssh -f -L 295.13.12.53:3306:10.18.81.36:3306 user#295.13.12.53
Explained:
ssh -f -L your_ssh_mashine_ipaddress:your_ssh_mashine_local_port:target_ipaddress:target_port user#your_ip_address -N
your_ssh_mashine_ipaddress - it is not local ip address, it is ip address
that you ssh to, in this example 295.13.12.53
your_ssh_mashine_local_port -this is custom port not 22, in this example it is 3306.
target_ipaddress - ip of the machine that you trying to dump DB.
target_port - 3306 this is real port for MySQL server.
user#your_ip_address - this is ssh credentials for the ssh mashine that you connect
Once all this done then go back to your machine and do this:
mysqldump -h 295.13.12.53 -P 3306 -u username -p db_name > dumped_db.sql
Will ask for password, put your password and you are connected.
Hope this helps.
Try this, Its working:
mysql -h {hostname} -u{username} -p{password} -N -e "{query to execute}"
This one worked for me in mysql 8, replace hostname with your hostname and port_number with your port_number, you can also change your mysql_user if he is not root
mysql --host=host_name --port=port_number -u root -p
Further Information Here
You should put your password with 'p'
mysql -u root -u 1.1.1.1 -p'MyPass'
I was too getting the same error.
But found it useful by creating new mysql user on remote mysql server ans then connect. Run following command on remote server:
CREATE USER 'openvani'#'localhost' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'openvani'#'localhost WITH GRANT
OPTION;
CREATE USER 'openvani'#'%' IDENTIFIED BY 'some_pass';
GRANT ALL PRIVILEGES ON *.* TO 'openvani'#'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
Now you can connect with remote mysql with following command.
mysql -u openvani -h 'any ip address'-p

If you are on windows, try Visual Studio Code with MySQL plugins, an easy and integrated way to access MySQL data on a windows machine. And the database tables listed and can execute any custom queries.
If port is default, some version required data base name which you trying to connect.
mysql -u <<your username>> -h <<your host>> <<your db name >> -p
This will prompt password Then type your password. If port is not default 3306
Then:
mysql -u <<your username>> -h <<your host>> -P <<your port>> <<your db name >> -p
Can anybody tell me that how to get DB backup script from Remote Server in MySQL using command-line utility?
I'm using a command as follows, but not working:
C:\>mysqldump -h <server ip> -u <user-id> -p <password> <db name> >
E:\dumpfilename.sql
The syntax for the password is wrong. You need to write the password immediately after the -p, without a space. That's why the password is interpreted as the database name.
Write this instead:
C:\>mysqldump -h <server ip> -u <user-id> -p<password> <db name> >
E:\dumpfilename.sql
Notice how there is no space after -p. An example would be -phunter2, where the password is "hunter2".
