我试图在我的服务器上部署Web应用程序,我得到这个mysql数据库异常"访问被拒绝用户'root'@'localhost'(使用密码:YES)(Mysql :: Error)"

我尝试从命令提示符访问数据库,Access denied for user 'root'@'localhost' (using password: YES) (Mysql::Error)我可以执行所有数据库操作.

什么是错误

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

我的基于Javascript的站点的用户经常需要创建一个事件,在该事件中他们发布事件名称,事件描述,开始时间和事件的结束时间以及日期.现在,他们想将这些活动详情添加到他们的Google日历或雅虎日历或iCal或Outlook,他们的标准库是什么？我试图弄清楚过去3天,虽然我知道谷歌api的,但我不知道iCal和Outlook甚至雅虎也.我正在寻找与此类似的" http://compute2011.doattend.com/ ".在右侧,您可以看到"将此添加到您的网站"部分,我想做同样的事情.

请帮我搞定.

我正在尝试在我的笔记本电脑上安装厨师和刀ec2插件来设置工作站.最初我使用厨师综合来安装厨师 - 客户端,但安装后我遇到了一些问题,所以一个快速的谷歌搜索让我到stackoverflow和几个线程建议我使用宝石安装厨师.我正在运行ruby 2.0.0-p0并且主厨和刀ec2已经安装了,但我现在遇到了另一个问题.我发布了这个问题,请好好看看.

请帮我解决这个问题

我正在寻找ruby on rails上的报告宝石或工具.它是一个电子商务应用程序,我需要生成大量的数据,如销售报告,营销报告等,我想让它更通用和开放,以便用户可以得到任何类型的报告.

我开发了Facebook应用程序,它克隆了我的网站的注册和sign_in部分.用户可以通过Facebook注册或登录我的网站.我创建了一个简单的HTML页面,并将该页面作为iFrame嵌入到facebook选项卡中.

当我以管理员的身份打开应用程序时,它工作正常,但当我让我的朋友检查出来时,它说页面无法加载并给出此错误

Error 102 (net::ERR_CONNECTION_REFUSED): The server refused the connection.

请帮我解决这个问题.

我正在运行tomcat server 6.0,当我尝试在此服务器上运行任何Web应用程序时,它给出了一个错误说"配置中定义的两个或多个Web模块具有相同的上下文根目录要启动此服务器,您需要删除重复项(一个或多个)".

我正在使用Eclipse 3.6 helios.

如何删除重复项？

我有几个bash脚本添加到指定时间的cron作业,但它需要以root用户身份执行.我正在尝试运行这些脚本,即crob作业,但它需要root用户权限,因为我在ubuntu ec2实例中运行此作业,其中root用户受到限制.以root用户身份运行这些脚本的工作原理是什么.

谢谢

我使用ruby企业版运行我的rails应用程序,独角兽作为app服务器.我运行这个命令

bundle exec unicorn -D -c /home/ubuntu/apps/st/config/unicorn.rb

我需要在系统重启或启动后立即运行此命令.我在ubuntu 10.04 LTS EC2实例上运行应用程序.我尝试了本网站以及本网站上提到的几个例子,但它对我不起作用.任何抬头

我已经创建了ubuntu 10.04 ec2映像,现在我需要在我的实例上安装tomcat apache和jdk6但是每当我使用命令sudo apt-get install sun-java6-jdk或者sudo apt-get install tomcat6 admin或者sudo apt-get install ec2-api-tools
