node.js的generic-pool与mysql结合，mysql连接池

var generic_pool = require(‘generic-pool‘);

var pool = generic_pool.Pool({

name: ‘mysql‘,

max: 10,

create: function(callback) {

var Client = require(‘mysql‘).createConnection({

host:‘127.0.0.1‘,

user:‘root‘,

password:‘123456‘,

database: ‘weibo_gs‘

});

callback(null,Client);

},

destroy: function(db) {

db.disconnect();

}

});

pool.acquire(function(err, client) {

if (err) {

// handle error - this is generally the err from your

// factory.create function

}

else {

client.query("select * from gs_scrapy", [], function(err,data) {

console.log(data);

// return object back to pool

pool.release(client);

});

}

});
