Mysql tcp port9/2/2023 ![]() Note that, enabling remote connections to MySQL server is not good practice from a security standpoint. Here 192.168.1.100 is the IP address of my Ubuntu Server where MySQL server is running. ![]() To test the connection, try to access the MySQL server from a remote computer: mysql -h 192.168.1.100 -u username -p CREATE USER identified by 'new-password' Then you can grant access to databases using the GRANT ALL command: GRANT ALL PRIVILEGES ON dbname.* TO you want to grant access to all databases on the server, run: GRANT ALL PRIVILEGES ON *.* TO you want to create a user that is only allowed to login from a specific host, replace '%' with host IP or domain name when creating the user. To create a mysql user that is allowed to connect from any host, login in the MySQL console and run: CREATE USER IDENTIFIED BY 'new-password' Now that our MySQL server allows remote connections, we still need to have a mysql user that is allowed to access the server from outside the localhost. nmap 192.168.1.100 Create Remote MySQL user and grant remote access to databases sudo ufw allow 3306/tcpĬlick the following link to learn more about UFW Ubuntu Firewall.įrom a another Linux machine, you can run nmap against your server IP to check whether port 3306 is open or not. UFW firewall is disabled by default in Ubuntu 18.04, so you don't have to worry about opening mysql port 3306 if you didn't enable UFW.īut if have enabled UFW then it will block the mysql remote access, so you need to add firewall rule to open the port 3306. bind-address = 0.0.0.0īy changing value to 0.0.0.0, we instruct MySQL to bind to all available interfaces and by doing that we allow remote connections to the MySQL Server on Ubuntu 18.04. To allow remote access, we changed the value of the bind-address to: "0.0.0.0". By default it is set to: "bind-address = 127.0.0.1" which prevents other hosts from accessing our mysql server. This setting is controlled by the bind-address in the MySQL/MariaDB configuration file. The output should be similar to the following: tcp 0 0 0.0.0.0:3306 0.0.0.0:* LISTEN 622/mysqld How it works.īy default the mysql daemon on Ubuntu 18.04 is only listening for connections on localhost (127.0.0.1), which mean you cannot login to the server from a remote computer. Run the netstat command and make sure that mysql server listen on socket 0 0.0.0.0:3306. Save the configuration file, and restart the MySQL server: sudo systemctl restart mariadb Under the section, locate the line: bind-address = 127.0.0.1 Open the /etc/mysql//50-server.cnf file (or /etc/mysql//mysqld.cnf). ![]() If you are using MariaDB Database server, configuration file going to be "/etc/mysql//50-server.cnf", If you have installed MySQL Database server configuration file is: "/etc/mysql//mysqld.cnf". Note that to allow mysql remote connections we need to edit the MySQL main configuration file. ![]() Which prevent us from accessing the database server from the outside. The default behavior of the Ubuntu MySQL Server blocks all remote connections. This tutorial explains how to allow remote connections to the MySQL/MariaDB server on Ubuntu 18.04.
