I have a MySQLdb running on my Ubuntu Laptop. I have created a database.
I need to access this database on my laptop from my Raspberry pi.
I have installed PyMySQL on my raspberry pi. I have also configured the mysqld.conf file in my laptop and commented out the bind address line.
But eherytime i use the following command on my RPi
conn = pymysql.connect(host='192.168.10.7', port='3306', user='root', passwd='password', db='temps')
192.168.10.7 is my laptop ip address. This IP address can be pinged from my RPi.
but i get error
pymysql.err.InternalError: (1130, "Host '192.168.10.7' is not allowed to connect to this MSQL server")
Do I need to make anymore changes in the configuration? If yes, can you please guide me?
By default MySQL Server on Ubuntu run on the local interface, This means remote access to the MySQL Server is not Allowed. To enable remote connections to the MySQL Server you need to change value of the bind-address in the MySQL Configuration File.
Open the /etc/mysql/mysql.conf.d/mysqld.cnf file (/etc/mysql/my.cnf in Ubuntu 14.04 and earlier versions).
Under the [mysqld] Locate the Line,
bind-address = 127.0.0.1
And change it to,
bind-address = 0.0.0.0
Then, Restart the Ubuntu MysQL Server.
systemctl restart mysql.service
Now Ubuntu Server will allow remote access to the MySQL Server, But still you need to configure MySQL users to allow access from any host.
For example, when you create a MySQL user, you should allow access from any host.
CREATE USER 'username'#'%' IDENTIFIED BY 'password';

I installed MySQL Server 8.0 on Windows Server 2019, during installation I created user 'superna' # ' %' with DBAdmin rights. When connecting from a local machine, there are no problems (mysql -u superna -p), but when trying to connect from a remote machine (mysql -h 10.165.1.20 -u superna -p), error 1045 is returned.
I checked the availability of port 3306 using nmap, port is open.
When installing mysql server on Windows 10, such problems are not observed, the connection from the remote machine works correctly. Can you tell me what point in the settings I might be missing?
Can you confirm if your my.cnf file have this line? If it hasn't, add it and restart mysql.
bind-address = 0.0.0.0
Problem solved. The server was configured to NAT port 3306 to another machine on the network.
I have visited many websites for remote connection of MariaDb.
I have executed the command as below to create user with password in sql.
GRANT ALL PRIVILEGES ON . TO 'root#(my server ip)' IDENTIFIED BY '(my password)'
And i've added one line below [mysqld] in the file of /etc/my.cnf.d
bind-address = 0.0.0.0
Then restart MariaDb service as below
sudo systemctl restart mariadb
Everything runs good.
However when i access by below command, it runs failed.
mysql -u root -p -h (my server ip)
I've turn off my firewall in my server, and turn on the port 3306 in GCP server, and it can be expected, i must fail to connect in my local machine.
Since you want to use a TCP connection, I assume that you want to connect to a remote server, not to a server running on the same machine.
Make sure that you are able to connect physically to the database server, e.g. with telnet server_ip:3306.
Determine the IP address of the computer from which you want to connect to the server (= client_ip).
Add a user on the server:
GRANT ... TO root#client_ip
If client and server are running on the same machine, the preferred way is to use a linux socket (user#localhost) which is way faster.
I'm trying to set up a MySQL server on Windows that will allow another computer to connect to it remotely. The client computer is getting a 'Can't connect to MySQL server' error in MySQL Workbench.
Both computers are on the same network, and the server is using a static IP address (I have forwarded ports in my router to allow external connections to the public IP address).
What I've tried (suggested by other threads):
In my.ini, setting bind-address = 0.0.0.0 / commenting out bind-address / commenting out skip-networking
Running GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'#'IP' IDENTIFIED BY 'PASSWORD';. When I run this, I get the error Using GRANT statement to modify existing user's properties other than privileges is deprecated and will be removed in a future release; however I can confirm that in Workbench, the user's privileges are all checked (under the 'Users and Privileges' screen).
In my router settings, forwarded port 3306 on the server's static IP address
Disabling the Windows Firewall on the server.
Verified that the MySQL Server Windows Service is running.
Can anyone advise?
Ref: Try connecting with mysql cli instead of work bench from the remote machine, so u can isolate that cli client u r able to access the remote DB. because the following reason might be causing connectivity issue in Workbench.
mysql cli cmd
install mysql.exe client program
from cmd prompt> mysql -hhostname -uusername -ppass dbname
Cannot connect to Database server (mysql workbench)
In MySQL Workbench (5.2.47 CE)
click Mange Server Instances (bottom right corner)
click Connection
in the Connection box select:
Local Instance ($ServerName) - root#127.0.0.1:3306 '<'Standard(TCP/IP)>
click Edit Selected...
under Parameters, Hostname change localhost or 127.0.0.1 to your NetBIOS name
click Test Connection
I deploy a mysql service on my company remote develop CentOS machine, I'm sure the service is turn on, and it can be access from an other reomte linux machine.
However, I can't connect it from my own Windows PC. I tried mysql workbench client and HeidiSQL client, both failed. I can ping through the remote IP address. I have tried anything I can found on google. Like
add bind-address = 127.0.0.1 to cnf file, and comment out the skip-networking.
I also tried the answer on another question Can't connect to remote server using MySQL Workbench on mac, which allow all machine can access to the service.
But my PC still can't connect to it, which report code 10060 error. So what should I do?
That bind-address = 127.0.0.1 config option means that your mysql server only accepts connections from the localhost, which is your actual CentOS machine. Make sure to set bind-address = 0.0.0.0.
Also, make sure that:
you have connectivity from your windows machine to the CentOS one
no firewall blocks the external connections to the local mysql port
Regarding potential security concerns from opening your mysql instance to the whole internet - first make it work, then make it better
I had the same issue here man,and i discovered that we need to create a user that isnt the root user. I my case, i don't know why yet, the issue was that.
The solution
Steps:
1 - Check the firewall (create a rule for port 3306 or disable it).
2 - Comment the line # bind-address=0.0.0.0 at [mysqld] config optin in C:\ProgramData\MySQL\MySQL Server 5.7\my.ini
3 - Create the user to remote access:
mysql> CREATE USER 'net'#'%' IDENTIFIED BY '123';
mysql> GRANT ALL PRIVILEGES ON *.* TO 'net'#'%' WITH GRANT OPTION;
In my case, solved.
I have been using ubuntu 14.04 LTS OS and now i want to give permission of my local mysql server for my colleague system in my network. I need the answes for the following question,
How to bind my system IP address to mysql server. If i execute the command line "mysql -uroot -proot -h192.168.1.198", then received the error message below
ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.1.198' (111)
Then how to give permission to other system user to access my local mysql server.
Your MySQL service is bound to serve localhost only (interface binding). This is the default for security reasons. If you really need to access it directly from other hosts, there is a nice How to enable remote access to MySQL on Ubuntu which you could follow:
as root, open your /etc/mysql/my.cnf with your favorite editor
look for the [mysqld] section, and in there for the bind-address keyword. This usually is set to 127.0.0.1 -- change that to match your "normal" IP-address
save the file, and reload the service (e.g. using service mysql restart)
Remember you must enable your remote users to access their database(s) from remote, by setting the appropriate GRANTs -- e.g.
GRANT ALL ON mydb.* TO remoteuser#'%' IDENTIFIED BY 'SomePASSWORD';
Note the #'%', which means "from any host".
Try to telnet MySql server from that PC
telnet 192.168.1.198 3306
If that fails there are two cases:
You have not properly opened MySql Server required ports (default: 3306)
Go to my.ini (or my.cnf) and comment out bind-address and change it to 0.0.0.0 (to listen to all available interfaces) or perhaps the server's LAN IP (192.168.1.XYZ).
