我的前端连接到我的服务器,其中主机在AWS,从昨天起我得到503服务暂时不可用的错误。
在chrome控制台中,我有两个错误:
1:
http://myServerendpoint.com/getData 503 (Service Temporarily Unavailable)
2:
Failed to load http://myServerendpoint.com/getData : No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://myFrontEndPoint.com' is therefore not allowed access. The response had HTTP status code 503.
我已经将cors应用于服务器(它是nodejs):
app.use(cors({
allowedOrigin: ["*"],
credentials: true
}))
它一直工作到昨天。但从昨天开始,我一直在犯这个错误,没有任何线索。在aws日志中,我了解到:
container_linux.go:247: starting container process caused âexec: \â/usr/bin/node\â: stat /usr/bin/node: no such file or directoryâ
知道怎么了吗?
更新时间:
路径错误,我将其更改为正确的路径,即/usr/bin/node,但现在我获得的权限被拒绝错误:
container_linux.go:247: starting container process caused "exec: \"/usr/bin/node\": permission denied"
我的docker文件:
FROM node:6-onbuild
RUN apt-get update && \
apt-get -y install sudo
RUN mkdir -p /usr/bin/node
RUN chmod -R +x /usr/bin/node
RUN sudo chown -R $USER: /usr/bin/node
WORKDIR /usr/bin/node
COPY package.json /usr/bin/node
RUN npm install
COPY . /usr/bin/node
ENV PORT 80
EXPOSE ${PORT}
CMD [ "npm","run", "start" ]
新更新:
即使在使用buildkite构建之后,duckerfile配置也可以正常运行:

所以问题不是在构建之前,而是在构建之后,当我们发送http请求时,我们的权限被拒绝了!
