我在Spring Tool Suite IDE中使用嵌入式Tomcat服务器。我的问题是,当我运行我的项目时,出现如下错误:
***************************
APPLICATION FAILED TO START
***************************
Description:
The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigur
当我试图在端口8080上运行一个服务(RavenDB)时,它会停止,而Windows日志显示了以下错误:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Net.HttpListenerException: Failed to listen on prefix 'http://+:8080/' because it conflicts with an existing registration
我正在尝试侦听端口8080的socket.io,但是我得到了错误:
http://localhost:8080/socket.io/?EIO=3&transport=polling&t=Lai1FQh net::ERR_CONNECTION_REFUSED
我正在使用来自数字海洋的ubuntu虚拟机,当我第一次登录ssh时,我收到消息:
The "ufw" firewall is enabled. All ports except for 22, 80, and 443 are BLOCKED。
我是这方面的初学者,但这并不意味着端口8080被阻塞。
我如何解决
我有一个节点项目,它还有Dockerfile和docker-compose.yml。
Dockerfile
FROM node:lts-alpine as build-stage
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
FROM nginx:stable-alpine as production-stage
COPY --from=build-stage /app/dist /usr/share/nginx/html
EXPOSE 80
CMD ["nginx"
我想在一个特定的端口上运行一个测试监听器,以检查该端口是否打开,但是每当我使用netcat启动一个监听器时,它都与0.0.0.0:8080 Ip地址绑定。我想启动一个通配符服务,比如:::8080 using netcat -l -p 8080或任何已知的方式。 我用来检查可用性的脚本 with closing(socket.socket(socket.AF_INET, socket.SOCK_STREAM)) as sock:
if sock.connect_ex((ip,port)) == 0:
print "Port is open";

当我在Eclipse中启动WildFly时,我得到了这个错误:
