Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

ssh2-connect-mysql

ssh2 connection mysql

为了网络安全起见,数据库和后端服务一般不会直接部署在同一台机器上,且一般也不允许直接用账户+密码的方式直接连接,通常采取的方案是通过 ssh 的方式进行连接。

步骤

  1. ssh 建立连接

  2. 与 mysql 建立连接

  3. 得到 mysql 操作句柄

用法

yarn add ssh2-connect-mysql

OR

npm i ssh2-connect-mysql

const ssh2mysql = require('ssh2-mysql');
const fs = require('fs');

// see config: https://github.com/mscdex/ssh2
const ssh_conf = {
  host: 'xxx.xxx.xx.1',
  port: 22,
  username: 'realzzz',
  privateKey: fs.readFileSync('/path/to/my/key')
};
// see config: https://github.com/sidorares/node-mysql2
const db_conf = {
  host: 'xxx.xxx.xx.2',
  user: 'realzzzdb',
  password: 'qwer123..',
  database: 'mydb'
};

// example sql statement
const sql_statement = 'INSERT INTO book(name, author) VALUES(?, ?)';
const params = ['JavaScript高级程序设计', 'Nicholas C. Zakas'];

ssh2mysql.connect(ssh_conf, db_conf)
  .then(sql => {
    sql.query(sql_statement, params, (err, res) => {
      if (err) {
        console.log(err);
      }
      // success
      console.log(res);
      ssh2mysql.close();
    });
  });
