Question

我的HapiJS + MySQL服务器在发出大量请求后仍然崩溃。

const MySQL= require('mysql');
const pool = MySQL.createPool({
      host     : 'localhost',
      user     : 'aUser',
      password : 'aPWD',
      database : 'DB'
    })};

pool.getConnection(function(err, connection) {
    query = 'SOMETHING';

    connection.query(query,function (error, results, fields){
                connection.release();
                reply(results);

    });

});

我的感觉是错误发生，因为池用完了连接？它失败，因为connection未定义。

这是错误：

我通过将值socketPath的{{1}}添加到数据库配置来解决了我的问题

/var/run/mysqld/mysqld.sock

这可能有助于有同样问题的人reference

HapiJS＆amp;一段时间后MySQL崩溃了
