I have a hosting account, on database section i have "MySQL® Databases",
"MySQL® Database Wizard","phpMyAdmin" and "Remote MySQL" Options
Error i am getting is
Database ErrorHost 'adonis.havehost.com' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts'
Write a server application that sends the query:
FLUSH HOSTS
to MySQL.
If you have shell access to the server, you can login and do:
mysql -u root -p -e 'flush hosts'
This must solve your issue.
mysql -u root -p -e 'flush hosts'
mysql -u root -p -e 'flush hosts'
And you can even contract your server provider
In MySql,run the following query:
FLUSH HOSTS;
Using mysqladmin you can execute this command:
mysqladmin flush-hosts;
and
mysqladmin flush-status;
This will remove the error shown by your MySQL server.
log in to your server by putty SSH, and just type this command
mysql -u root -p -e 'flush hosts'
and enter your root password after that your host name will be flushed , with out showing any massage in Shell.

I'm trying to connect to a database and I'm getting this error:
ERROR 1130 (HY000): Unknown error 1130
Here is a command which I'm using:
mysql --host HOSTNAME --user MYUSERNAME -p MYDATABASENAME
I'm using Arch Linux. Thanks in advance for the help !
mysql --host HOSTNAME --user MYUSERNAME -p MYDATABASENAME
MYDATABASENAME - Should be Password not DatabaseName..
Syntax:
shell> mysql --host=localhost --user=myname --password=password mydb
shell> mysql -h localhost -u myname -ppassword mydb
Ref: https://dev.mysql.com/doc/refman/5.7/en/connecting.html
ERROR 1130 translates into Host '<hostname/IP>' is not allowed to connect to this MariaDB server, not sure why you see it as unknown error.
It means that there are no users configured with host=<your hostname/IP> on the server where you are connecting to -- that is, there is no user MYUSERNAME#<your hostname/IP>, or even <anything>#<your hostname/IP>, or <anything>#'%'.
Hi this is similar to phpMyAdmin Remote Access
Basically you have to first configure remote access. Here is a link for MariaDB on Arch Linux remote access configuration. https://dominicm.com/install-mysql-mariadb-on-arch-linux/
Edit config locally.
Config file sudo nano /etc/mysql/my.cnf
Grant privilege to table for user
GRANT ALL PRIVILEGES ON databasename.* TO 'dbusername'#'%' IDENTIFIED BY 'dbpassword';
Restart Mysql/MariaDB
Hopefully this helps.
try mysqld --skip-grant-table
Not sure why but it helped my teammate as she reported.
More details here. https://www.howtoforge.com/setting-changing-resetting-mysql-root-passwords
I am trying to figure out what the mysql -u root -p command does.
I have googled the command but I can't find any good results.
mysql -u root -p means, that you trying to connect to MySQL shell with parameters - -u parameter specified MySQL user name.
-u, --user=name User for login if not current user.
In your case it's root user.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's asked from the tty.
You can type mysql --help from the command line for more information about all available parameters.
Good luck.
It logs you into mysql as the root user. After -p (Immediately after it incidentally, no spaces) you would include the password.
`mysql -u root -p`
Its initiate a connection of MySQL.
-u means that we are going to connect with a username root
-p means that we will enter username's password
Check man mysql
Your command tries to connect to MySQL on localhost with user "root" and asking for a password
I have gone through similar cases listed here but it doesn't seem to work.
I was using MySQL Workbench to establish a connection with my database which is hosted on another server. Tried a few times and unable to connect followed by this error. I am confused as to where I should even do this flush. On PhpMyadmin under the SQL query? Cos when I tried to input the following command, it returns as syntax error. I am using a windows OS thus no shell shell scripting for me to input this information either. I am accessing the database temporarily via Cpanel/ phpmyadmin now.
Please help to tell where I should input this data and if my syntax is wrong. Thanks for help.
mysqladmin flush-hosts;
or
mysqladmin -umyname -pmypassword flush-hosts;
My error message as follows:
Failed to connect to MYSql at 192...* with user myName
Host 'host-92...*.as13285.net' is blocked because of many connection
errors; unblock with 'mysqladmin flush-hosts'
mysqladmin is not a SQL statement. It's a little helper utility program you'll find on your MySQL server... and "flush-hosts" is one of the things it can do. ("status" and "shutdown" are a couple of other things that come to mind).
You type that command from a shell prompt.
Alternately, from your query browser (such as phpMyAdmin), the SQL statement you're looking for is simply this:
FLUSH HOSTS;
http://dev.mysql.com/doc/refman/5.6/en/flush.html
http://dev.mysql.com/doc/refman/5.6/en/mysqladmin.html
You should put it into command line in windows.
mysqladmin -u [username] -p flush-hosts
**** [MySQL password]
or
mysqladmin flush-hosts -u [username] -p
**** [MySQL password]
For network login use the following command:
mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
you can permanently solution your problem by editing my.ini file[Mysql configuration file]
change variables max_connections = 10000;
or
login into MySQL using command line -
mysql -u [username] -p
**** [MySQL password]
put the below command into MySQL window
SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;
check veritable using command-
show variables like "max_connections";
show variables like "max_connect_errors";
You can easily restart your MySql service. This kicks the error off.
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.
For more details see:
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
I got a database server failure, says host is blocked because of many connection errors. It ask me to unblock with 'mysqladmin flush-hosts'
how and where should I run this command to our amazon rds database server?
thank you
For normal MySQL, just connect as the 'root' administrative super user, and issue the command:
FLUSH HOSTS
Even in the case of too many connections, MySQL should be keeping a connection in reserve so that a super user can connect.
The mysqladmin client generally connects as root anyway and issues the above SQL.
Login to any other EC2 instance you have that has access to the RDS instance in question and has mysqladmin installed and run
mysqladmin -h <RDS ENDPOINT URL> -P 3306 -u <USER> -p flush-hosts
you will be prompted for your password
When an Amazon RDS instance is blocked because the value of max_connect_errors has been exceeded, you cannot use the host that generated the connection errors to issue the "flush hosts" command, as the MySQL Server running on the instance is at that point blocking connections from that host.
You therefore need to issue the "flush hosts" command from another EC2 instance or remote server that has access to that RDS instance.
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
If this involved launching a new instance, or creating/modifying security groups to permit external access, it may be quicker to simply login to the RDS user interface and reboot the RDS instance that is blocked.
I fixed this error on my RDS instance by rebooting it from the AWS management console. HTH
[edit: lol downvotes]
On Amazon RDS FLUSH HOSTS; can be executed from default user ("Master Username" in RDS info), and it helps.
Since the hosts is blocked. try connect it from other host and execute the mysqladmin flush-hosts command.
mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
You will have to connect your RDS through a computer which as mysql installed on it
I used one of my hosting VPS using SSH
After i was logged in my VPS ( i used putty ) It was simple, in the prompt i entered the following command:
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
You can restart the database on RDS Admin.
You can flush hosts local MySQL using following command:
mysqladmin -u [username] -p flush-hosts
**** [MySQL password]
or
mysqladmin flush-hosts -u [username] -p
**** [MySQL password]
Though Amazon RDS database server is on network then use the following command as like as flush network MySQL server:
mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts
mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts
In additional suggestion
you can permanently solve blocked of many connections error problem by editing
my.ini file[Mysql configuration file]
change variables max_connections = 10000;
or
login into MySQL using command line -
mysql -u [username] -p
**** [MySQL password]
put the below command into MySQL window
SET GLOBAL max_connect_errors=10000;
set global max_connections = 200;
check veritable using command-
show variables like "max_connections";
show variables like "max_connect_errors";
got this error today on a customer rds while they were using Heidi Sql client.
We simply used 'mysqlroot' on the ec2 that talks to the rds in question to connect, followed by issuing the 'flush hosts;' cmd.
