When using a combination of pi / windows it gives a headache as some work some don’t. In my mind it would be better if it was at least an array that you could go through. Running a project on a Raspberry Pi has the same effect, it pulls the loopback instead of eth0, on a windows PC the tag is fine through. When configuring a MySQL database server, it is important to bind it to an IP address by respecting some security strategies.This is definitely a bug/undesirable consequence. The related article above explains how to bind a MySQL server to an IP address. How to Bind a MySQL Server to an IP Address?.Theoretically, if too many interfaces were specified by the –bind-address option, it could result in the “Too many open files” error if the MySQL server configuration had already opened a large number of files. Every created server socket counts against the limit specified by the –open-files-limit option. ![]() MySQL tried to bring more facilities by allowing multiple addresses to listen, but there is a side effect. Then, restart the firewall service: $ sudo ufw disable & sudo ufw enable Conclusion Instead of using the IP address, we will use the interface name corresponding to each IP address: $ sudo ufw allow in on ens33 to any port 3306 $ sudo ufw allow in on ens34 to any port 3306 $ sudo ufw allow in on ens35 to any port 3306 We will only allow MySQL port 3306 to the specified IP address (interfaces) that we have checked before for additional security. Now that you have configured MySQL and the user for the remote database access, you need to allow the MySQL protocol within your firewall. Change ‘localhost’ to your remote MySQL server’s IP address or full hostname. ssh -L localhost:2000:localhost:3306 serverpilotSERVERIPADDRESS. Mysql> GRANT ALL PRIVILEGES ON userdb.* TO FLUSH PRIVILEGES To create an SSH tunnel from Mac or Linux, you can run the command line SSH command with the -L to enable local port forwarding. We will create the database and the user below to show you the process: mysql> CREATE USER IDENTIFIED BY 'your_db_password' You can connect to MySQL and allow remote access. You should make sure the database user you are using is allowed remote access to your database. Make sure you have your remote database user: Allow Remote Access for the MySQL User NB: The mysqlx-bind-address directive is for the X plugin, which is the interface between the MySQL server and the clients. ![]() Restart the MySQL service to save the modifications: $ sudo systemctl restart mysql The directive to edit is the bind-address. If you want to configure MySQL and bind the IP addresses, you should edit the configuration file /etc/mysql//mysqld.cnf and change the default IP address value by separating each address with a comma. Configure MySQL Binding for Multiple IP Addresses You can see that our server has the following IP addresses: We will choose a Pay-As-You-Go instance:Ĭontinue with the configuration of your instance until the end:Ĭheck Your IP Interfaces and IP Addressesīefore binding your IP addresses to MySQL, it is important to check your IP so you will not make a misconfiguration afterward: $ ip a Log in to your Alibaba Cloud account and go to Elastic Compute Service (ECS):Ĭreate a new instance. The following step-by-step guide explains how to run your MySQL server from the Alibaba Cloud console. This way, it can allow specifying bind-addresses for several network interfaces. It could be useful to allocate more than one network interface for specific use. The MySQL server listened to incoming connection requests on one or all configured network interfaces by default. ![]()
