8/26/2023 0 Comments Mysql port 3306 in useIf the address is an IPv4-mapped address, the server accepts TCP/IP connections for that address, in either IPv4 or IPv6 format. If the address is ::, the server accepts TCP/IP connections on all server host IPv4 and IPv6 interfaces. If the address is 0.0.0.0, the server accepts TCP/IP connections on all server host IPv4 interfaces. Use this address to permit both IPv4 and IPv6 connections on all server interfaces. ![]() If the address is *, the server accepts TCP/IP connections on all server host IPv6 and IPv4 interfaces if the server host supports IPv6, or accepts TCP/IP connections on all IPv4 addresses otherwise. We needed to bind MySQL to both localhost and a network interface, but according to the official documentation, MySQL can be bound to just one address at once in order to accept connections, this address’ value being one of the following: The Explanation About binding MySQL to external interfaces Grant the privileges you need to this user on the desired schemas and tables, or just grant all (strongly not recommended for production environments, select just the needed privileges instead): GRANT ALL PRIVILEGES ON *.* TO would be all. Optionally, create an user to give remote access to, or just skip this step and use an existing one: CREATE USER IDENTIFIED BY 'barpassword' Then reload the firewall configuration firewall-cmd -reloadĪs stated above, if it didn’t work because of command not found errors, open the port with the command below, replacing and with your system setup: iptables -I INPUT -i -p tcp -destination-port -j ACCEPTĮxample: iptables -I INPUT -i eth0 -p tcp -destination-port 3306 -j ACCEPT 3 – Grant remote access to a MySQL user Run the command below for any zone shown on the screen, replacing and with your system’s current setup: firewall-cmd -zone= -add-port=/tcp -permanentĮxample: firewall-cmd -zone=public -add-port=3306/tcp -permanent Which could print a single public zone or a few, like public and dmz. The first thing here is to find your active zone(s), this can be done by the following command: firewall-cmd -get-active-zones If your operational system is CentOS 7 or superior, you might be able to control your firewall rules through firewall-cmd commands, but if it fails with a command not found error, move straight to the iptables command. MySQLs default port is 3306, but if you are running your MySQL installation on a different port, replace 3306 at the next steps with your current port. Save and close the file, then restart MySQL: service mysqld restart 2 – Open MySQL firewall port If the parameter skip-networking exists, comment it with a leading #.If the parameter bind-address exists, comment it with a leading #.Locate the section in the file, which may look like the following: Then edit the file we’ve just found: sudo vi /etc/my.cnf ![]() Which might print something like the following: /etc/my.cnf Locate your my.cnf file running the command below: locate my.cnf I am going straight to the solution to make your MySQL avaiable for remote access, but you can find a detailed explanation at the end of this post. It is important to mention that the following solution was tested against CentOS 7.2, but it’s very likely to work on other Linux versions and/or distributions. ![]() The ProblemĪ fresh MySQL installation has its remote access disabled by default for security reasons, however, it can be enabled by taking a few simple steps. Restart your device and check the status.This tutorial will show how to enable MySQL remote access in order to make it accept connections from the network instead of just local connections. Now explore the following locations and delete following folders.Īnd if exists, delete the folder from the location. Select the View tab and select Show hidden files and folders. Run Command Prompt as Administrator and execute the following command to stop and remove MySQL service.Ĭlick on Start, type in Show hidden files and folders. If you need any of that data, be sure to back it up. Go to Control Panel > Programs and Features > Select MySQL > Click on Uninstall.Īfter you have uninstalled MySQL through Add/Remove programs, you now need to remove the existing database information which includes your actual data. If you are on a Windows machine, I suggest you to follow the steps mentioned below to uninstall MySQL from the device.
