mysql使用
安装mysql 模块:
在安装根目录 cmd命令行执行命令
npm install mysql
安装成功后、
mysql数据库表 已存在的情况下。
在nodejs根目录 新建mysql.js:
var sys = require('util'); var mysql=require('mysql'); console.log('正在连接MySQL...'); var http = require("http"); var server=http.createServer(function(request, response) { response.writeHead(200, {"Content-Type": "text/html;charset:utf-8"}); response.write("<!doctype html><html><meta charset='utf-8'/>"); var client = mysql.createConnection({'host':'localhost','port':3306,'user':'testmysql','password':'123456'}); clientConnectionReady = function(client) { client.query('use test', function(error, results) { if(error) { console.log('ClientConnectionReady Error: ' + error.message); client.end(); return; }else{ response.write("nodejs 服务器已经开始工作...<br/>"); response.write("已经连接上MySQL....<br/>"); } clientReady(client); }); }; clientReady = function(client) { var values = ['不错啊']; client.query('insert into nodemysql set names = :1', values, function(error, results) { if(error) { console.log("ClientReady Error: " + error.message); client.end(); return; } console.log('Inserted: ' + results.affectedRows + ' row.'); console.log('Id inserted: ' + results.insertId); } ); getData(client); } getData = function(client) { client.query( 'select * from nodemysql', function selectCb(error, results, fields) { if (error) { console.log('GetData Error: ' + error.message); client.end(); return; } var data = ''; for(var i=0; i<results.length; i++){ var firstResult = results[i]; data += 'id: ' + firstResult['id']+' name: ' + firstResult['names']+"<br/>"; } response.write(data); response.write("关闭MySQL连接..."); response.write("</html>"); response.end(); } ); client.end(); }; clientConnectionReady(client); }); server.listen(8033,"127.0.0.1"); var sys = require("util"); sys.puts("Server running at http://localhost:8033/"); 运行 node mysql.js 。
浏览器 访问 http://localhost:8033 即可看到效果。
配置oracle支持
在oracle网站下载oracle数据库客户端连接包
instantclient-basic-linux，instantclient-sdk-linux
解压oracle客户端连接模块
$ unzip instantclient-basic-linux-11.2.0.3.0.zip $ unzip instantclient-sdk-linux-11.2.0.3.0.zip $ sudo mv instantclient_11_2/ /opt/instantclient $ cd /opt/instantclient $ sudo ln -s libocci.so.11.1 libocci.so $ sudo ln -s libclntsh.so.11.1 libclntsh.so
