# Example MySQL config file for small systems.## This is for a system with little memory (<= 64M) where MySQL is only used# from time to time and it‘s important that the mysqld daemon# doesn‘t use much resources.## You can copy this file to# C:/xampp/mysql/bin/my.cnf to set global options,# mysql-data-dir/my.cnf to set server-specific options (in this# installation this directory is C:/xampp/mysql/data) or# ~/.my.cnf to set user-specific options.## In this file, you can use all long options that a program supports.# If you want to know which options a program supports, run the program# with the "--help" option.# The following options will be passed to all MySQL clients[client] password = 123456port = 3306 socket = "C:/xampp/mysql/mysql.sock"# Here follows entries for some specific programs # The MySQL server[mysqld]port= 3306socket = "C:/xampp/mysql/mysql.sock"basedir = "C:/xampp/mysql" tmpdir = "C:/xampp/tmp" datadir = "C:/xampp/mysql/data"pid_file = "mysql.pid"# enable-named-pipekey_buffer = 16Mmax_allowed_packet = 1Msort_buffer_size = 512Knet_buffer_length = 8Kread_buffer_size = 256Kread_rnd_buffer_size = 512Kmyisam_sort_buffer_size = 8Mlog_error = "mysql_error.log"# Change here for bind listeningbind-address="0.0.0.0" # bind-address = ::1 # for ipv6# Where do all the plugins liveplugin_dir = "C:/xampp/mysql/lib/plugin/" # Don‘t listen on a TCP/IP port at all.

　　可直接复制使用：

注意注意！！！！！！一定要将

：# Change here for bind listening
bind-address="0.0.0.0"  配置成0.0.0.0  表示可远程：

 链接名字随便填：主机名字为阿里云公网IP

 点击：Mysql那栏start连接后 点击config就会跳出配置文件：

按我上面的配置就ok了：
