I have a MySQL Server on some workplace running, now I want to connect to it from my homeplace, get the databases, etc...
I have the IPAdress of the workplace computer, but I cannot get access to it from my home MySQL Program if I enter the ip-adress in the connection string...
seems not to be accessible from publice.. is it possible to do it nevertheless? or impossible?
With MySQL you need to grant access to the IP you're trying to connect to it from..
GRANT USAGE ON *.* to root#xxx.xxx.xxx.xxx IDENTIFIED BY 'rootPassword';
GRANT ALL PRIVILEGES ON *.* TO root#xxx.xxx.xxx.xxx WITH GRANT OPTION;
Where XXX.XXX.XXX.XXX is the IP of the machine your trying to connect from, which you can find out by typing in google, "whatsmyip"
If you have a firewall enabled on your workstation, you also must permit your IP in the firewall as well.
You need also change bind-address in MySQL configuration. Default MySQL is running on localhost (127.0.0.1), you need change it to 0.0.0.0 (all interfaces).
If you don't have public address IP, you need use some VPN, read another topic: https://askubuntu.com/questions/64016/access-workstations-without-public-ip-maybe-with-vpn

I want to connect to a remote mysql database and fill in an IP address, but what is prompted here is another IP address（My local ip). What should I do? How can I solve it?
I haven't searched related questions, only found a jdbc: rmi://, but mysql does not seem to need rmi.
The connection to the remote server succeeded. But the user connecting is not allowed to. The message you've got is from MySQL.
So you need to use a user that can connect remotely or you need to grant access for 'root'#'171.221.xxx.yyy' e.g. GRANT ALL PRIVILEGES on database.* to 'root'#'171.221.xxx.yyy' identified by 'aPassword'
I've looked in so many areas to try to fix this problem and I can't seem to find a solution. Im running ubuntu linux with the latest mysql and phpmyadmin installation. I found that connecting to the database locally works but if I try to connect remotely it keeps denying the connections. The only way I can login to phpmyadmin is if I put the ip address in the bar, connecting via the web address will not work.
Are you trying to connect to MySQL remotely or PHPMyAdmin remotely?
If you are trying to access MySQL remotely, you need to do the following:
Edit the bind-address variable in /etc/my.cnf, to 0.0.0.0 or the IP address of your server
Make sure your MySQL user has permissions from remote hosts, do this using:
CREATE USER 'myuser'#'localhost' IDENTIFIED BY 'mypass';
CREATE USER 'myuser'#'%' IDENTIFIED BY 'mypass';
Then:
GRANT ALL ON . TO 'myuser'#'localhost';
GRANT ALL ON . TO 'myuser'#'%';
Then go ahead and restart the mysql instance on your server. This also assumes you have set IP tables up to allow port 3306 TCP incoming to your server.
I am not so into DB and I have the following problem.
I have installed a MySql 5.7.17 on a remote Ubuntu 16.04 server and I have to connect to this server from a client installed on my laptop.
So The first thing that I have done is that I have changed the bind-address directive values (into the /etc/mysql/mysql.conf.d/mysqld.cnf file) from:
Bind-address=127.0.0.1
to:
bind-address = 0.0.0.0
to allow also external connection.
The problem is that when I try to connect from my client (installed on my laptop) I obtain this error:
Host 'XXX.YYY.ZZ.JJ' is not allowed to connect to this MySQL server
(where **XXX.YYY.ZZ.JJ* is my laptop IP address).
From what I have understood I also have to give to the mysql user w the db permissions to connect from any host and not just from localhost.
I think that it should be something related to the grant: https://dev.mysql.com/doc/refman/5.5/en/grant.html
What exactly have I to do? I think that I have to access to MySql from my server shell (via SSH) and then perform a query that grant some privileges to the root user (the MySql user) to allow to access from outside.
But I don't know what exactly I have to do. How can I allow this external connection for the roo user?
As you mentioned, you need to login to mysql server with root access and then run following command on mysql prompt
GRANT ALL PRIVILEGES ON your_db_name.* TO 'your_db_user_name'#'%' IDENTIFIED BY 'newpassword';
you can also specify a specific IP instead of %
GRANT ALL PRIVILEGES ON your_db_name.* TO 'your_db_user_name'#'your_IP_here' IDENTIFIED BY 'newpassword';
you can also specify a for all databases
GRANT ALL PRIVILEGES ON *.* TO 'your_db_user_name'#'your_IP_here' IDENTIFIED BY 'newpassword';
I need to connect a desktop application to a MySQL server. The website connect to the database 'localhost'. What would the the full path of the localhost be?
Using CentOS 6.5/apache/zpanel
The answer is probably so obvious that nobody has ever asked it before. But I rally can't figure it out. Here is the screenshot of what I have:
It's the IP address of the server which is running mysql (the same of the webserver, if you're connecting to it as localhost)
But many hosting companies disable remote MySQL by default, you may need to ask them to enabled it, or to whitelist the IP you are connecting from.
You have to grant access to the user you are using to connect from remote, on your case the root user so:
GRANT ALL PRIVILEGES ON *.* TO 'root'#'%'
IDENTIFIED BY 'password' WITH GRANT OPTION;
After this run this other command to refresh the new privileges
FLUSH PRIVILEGES;
The '%' is the option that you allow root to connect from anywhere. You can specify also an IP address.
I have my dev environment set up as a Ubuntu Server (with LAMP installation) inside a vmware. The vmware is running on my local windows 7 machine. When I try to access my mysql server via HeidiSQL program the connection fails. I get a:
Server Error 2003, can't connect to mysql server on <IP ADRESS HERE>
I can however access the db server via PhpMyAdmin. MySQL is running and my connection credentials and port are all correct.
I read that you should enter the IPs of the computer you are trying to connect from as the "bind address" in the my.cnf file. Which I did. I tried both the internal network IP as well as the online IP. Still no luck, same message.
Since this isn't a production environment I would ideally like to allow anyone to access that server, not limit it by IP. Especially since my ISP assigns dynamic IPS. So I would have to change it all the time, assuming that even works.
So does anyone know how I can connect to my MySQL server from a remote computer?
P.S. I assume this is something developers have to deal with that's why I posted it here and not Super User. If it must be migrated please send it to Server Fault not Super User.
Ok, be aware this gives the world and his dog access to your mysql server.
GRANT ALL ON *.* to '%'#'%' WITH GRANT OPTION;
But say you are on your home network of 192.168.1.2/16 then you can at least limit it like this.
GRANT ALL ON *.* to '%'#'192.168.%' WITH GRANT OPTION;
Another option is that you have a user and password but want to connect from anywhere
GRANT ALL ON *.* to 'mysecretuser'#'%' IDENTIFIED BY 'mysecretpassword' WITH GRANT OPTION;
first check the ip assigned to vmware using from cmd
ipconfig/all
suppose ipassigned to vmware is 192.168.11.1
now in vmware in ubuntu check the ipadress
ifconfig
suppose ip adress of ubuntu is 192.168.11.137
now open mysql configurations
sudo nano /etc/mysql/my.cnf
change the bind address to ubuntu ip address
bind-address = 192.168.11.137
restart mysql
now connect to mysql
mysql -u root -p
and create a user with all privileges and host ip of vmware i.e 192.168.11.1
GRANT ALL ON db.* TO user#'192.168.11.1' IDENTIFIED BY 'PASSWORD';
now try to connect from windows.
also open port of mysql
/sbin/iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT
restart mysql and try to connect on ubuntu host ip address 192.168.11.137
For Heidi SQL I was able to get it to work following the instructions on this article:
http://mysql-tools.com/en/articles/http-tunnel/73-heidisql-a-http-tunnel.html
It uses a program called HTTP Tunnel. It's a lot slower but at least it works. If you use Navicat it comes with a PHP file that you can upload to your server and it will connect via that.
