从EC2实例i-78a8df00,我正在尝试连接到RDS实例mysql.************.us-east-1.rds.amazonaws.com.他们都在美国东部地区.我将EC2实例的安全组(sg-********)添加到RDS安全组,但这没有帮助.它似乎是防火墙/ DNS问题,因为它在运行此命令时超时:
ubuntu@ip-10-195-189-237:~$ mysql -h mysql.************.us-east-1.rds.amazonaws.com
ERROR 2003(HY000):无法连接到'mysql上的MySQL服务器.************.us-east-1.rds.amazonaws.com'(110)
我可以使用与上面相同的行从本地计算机连接到RDS实例.我尝试了各种论坛解决方案,但那些没有帮助.
我在我的React项目中使用重构 https://github.com/acdlite/recompose/
这是一个很棒的图书馆.我正在使用该compose实用程序作为容器组件,将状态向下作为道具传递给表示组件,如下所示:
const enhance = compose(
lifecycle({
componentDidMount() {
myCall
.getResponse([productId])
.then(products => {
setIsReady(true);
});
},
}),
withState('isAvailable', 'setIsAvailable', false),
withState('isReady', 'setIsReady', false),
mapProps(({
setIsAvailable,
setIsReady,
...state,
}) => ({
onLogoutTouchTap: () => {
...
请注意其中的setIsReady(true)电话componentDidMount.这是我想要做的,但是lifecycle/componentDidMount无权访问setIsReady.如何componentDidMount通过重构来完成更新状态的预期结果？
我尝试下载并使用gcloud bash工具来管理我的帐户,但是我使用该工具所做的一切都非常慢.MINUTES需要回复键入的命令.
是否可能需要在我的路由器或其他东西上打开防火墙以使其快速运行,就像它应该的那样？例如,此视频中的"安装..."行https://youtu.be/4y4-xn4Vi04?t=1m21s - 您会发现它们在几秒钟内完成了教程.在我的机器上完成这需要10多分钟.
我正在使用更新的Macbook Air,而所有其他互联网/等等都非常快.AT&T Uverse(30mbps/3mbps)的互联网连接速度很快.所有其他浏览都快速而且很好,我唯一能解决的问题是这个gcloud工具.
谢谢!标记
我随机(并且一直)在uwsgi中得到一根破损的管道......如下所示.知道是什么导致这个或我如何调试？
我在django(tastypie),uwsgi,nginx,并在aws上运行m3.medium(ubuntu 14.04).

[pid: 1516|app: 0|req: …我在Google Cloud上使用Kubernetes部署了Meteor应用程序,配置了Nginx作为SSL终止.一切正常.
但是,似乎如果两个不同的客户端连接到两个不同的SSL容器,则更新不会在相应的应用程序上显示最多10秒,这使得Websockets看起来不起作用,但轮询正在生效.我已确认所有客户端都与Websockets连接,但由于更新不会立即传播,因此Nginx可能未配置为与Meteor应用程序正确通信.
这是我的SSL/Nginx服务:

升级到ElCapitán为我的Meteor应用程序后,我遇到了无法通过Xcode iOS模拟器登录的问题.我重新安装了Xcode,但这似乎没有帮助.
然后我从我的Meteor应用程序(cordova-plugin-statusbar@1.0.1,ionic-plugin-keyboard@1.0.4)中删除了我的cordova插件,清除了.meteor/local/cordova-plugins,然后去重新测试我的应用程序:

Adding platform iOS to Cordova project
=> Errors executing Cordova commands:
While adding platform iOS to Cordova project:
Cordova error: CordovaError: Failed to fetch platform ios
Probably this is either a connection problem, or platform spec is incorrect.
Check your connection and platform name/version/URL.
