Open Mysql 3306 port remote access under Ubuntu 16.04

Original address: Portal

0. Preface

I saw a lot of open Mysql remote access ports on the Internet, but I couldn't find the modified configuration files.

Checked out my Linux version specifically

$ sudo lsb_release -a

The display is as follows:

Distributor ID: Ubuntu
Description:    Ubuntu 16.04.1 LTS
Release:        16.04
Codename: Great

 

1. Check whether port 3306 is normal

root@node1:~# netstat -an | grep 3306
tcp        0      0 127.0.0.1:3306          0.0.0.0:*               LISTEN

Note: The current IP address bound to port 3306 is the local 127.0.0.1

 

2. Modify the Mysql configuration file (note the path, which is different from many previous versions on the Internet)

root@node1:~# vim /etc/mysql/mysql.conf.d/mysqld.cnf

turn up

bind-address            = 127.0.0.1

Add # in front of it to comment out

 

3. Restart Mysql

root@node1:~# /etc/init.d/mysql restart
[ ok ] Restarting mysql (via systemctl): mysql.service.

 

4. Check the port information again

root@node1:~# netstat -an | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN

 

OK!
