# 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
```bash
yarn add ssh2-connect-mysql
OR
npm i ssh2-connect-mysql
```
```javascript
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();
});
});
```
