在 Mac OS 上将 Node.js 连接到 XAMPP MySQL 服务器时出现问题

Question

我一直在努力使用 MySql 模块将 Node.js 连接到我的 MySql DB。 数据库在我的 Mac 上通过 XAMPP 在本地运行。 这是我的连接脚本

var mysql_con = mysql.createConnection({
        socketPath: '/opt/lampp/var/mysql/mysql.sock',
        //port: '8080',
        host: '192.168.64.2',
        user: 'root',
        password: '',
        database: 'twitch_versus'
});
mysql_con.connect(function (err) {
        if(err) {
                console.log('mysql connect error: ' + err.stack);
                return;
        }
        console.log('mysql connected as ' + mysql_con.threadId);
});

运行此配置会出现此错误

我尝试使用套接字路径以及默认端口以及端口 8080。我尝试了 localhost、127.0.0.1 和您在上面看到的 ip。 我的 my.cnf 不包含绑定地址字段，并且跳过网络被注释掉。 使用端口 8080 和 localhost 时，大约 30 秒后出现此错误

返回

UNIX socket:        /opt/lampp/var/mysql/mysql.sock

像往常一样，非常感谢任何建议。

编辑 1：添加了 my.cnf

# Example MySQL config file for medium systems.
#
# This is for a system with little memory (32M - 64M) where MySQL plays
# an important part, or systems up to 128M where MySQL is used together with
# other programs (such as a web server)
#
# You can copy this file to
# /etc/my.cnf to set global options,
# mysql-data-dir/my.cnf to set server-specific options (in this
# installation this directory is /opt/lampp/var/mysql) 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   = your_password
port        =3306
socket      =/opt/lampp/var/mysql/mysql.sock

# if all processes that need to connect to mysqld run on the same host.
# All interaction with mysqld must be made via Unix sockets or named pipes.

# (via the "enable-named-pipe" option) will render mysqld useless!

# Replication Master Server (default)
# binary logging is required for replication
# log-bin deactivated by default since XAMPP 1.4.11
#log-bin=mysql-bin

# required unique id between 1 and 2^32 - 1
# defaults to 1 if master-host is not set
# but will not function as a master if omitted
server-id   =1

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
#
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>
#
# binary logging - not required for slaves, but recommended

编辑2：我认为我在评论的帮助下取得了进展。 我正在使用以下代码进行测试，它只是一个连接脚本

var mysql = require('mysql');

var con = mysql.createConnection({
  host: "192.168.64.2",
  user: "root",
});

con.connect(function(err) {
  if (err) throw err;
  console.log("Connected!");
});

这抛出

使用 nc -vz 192.168.64.2 3306 给出成功连接消息

Answer 1

当我尝试使用root登录时，我的机器上也出现了这个错误。 问题是 XAMPP 在自己的虚拟机中运行，因此他的localhost与我的 Mac 的localhost不同。 我已经通过在phpMyAdmin中创建一个具有主机名%的新用户来修复它，因此可以从任何地方访问它。

Answer 2

通过授予对 mysql 中所有数据库的访问权限来解决。

Answer 3

如果您使用的是带有 M1 芯片的 macOS，则为此使用 go

常量 mysql = 要求（'mysql2'）；

让池 = mysql.createPool({

host: '127.0.0.1',
user: 'root',
password: '',
database: 'database-name',

}）。承诺（）;

module.exports = 池；
