Rabbitmq安装及连接错误问题
本人在学习spingcloud的时候，学习到消息总线时遇到的问题，
首先需要安装下载Rabbitmq
借鉴这位博主的文章：
添加用户修改密码：
我的配置： host:也可以写成127.0.0.1本机端口。远程请写成自己本地的端口 就是因为我自己新添加的用户没有修改权限就出现了第三种错误：
找了好多资料，看到了这个：
1、如果写错了host （如：factory.setHost(“locathost”); ）报错
Exception in thread “main” java.net.UnknownHostException: locathost at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:195) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:529) at com.rabbitmq.client.impl.FrameHandlerFactory.create(FrameHandlerFactory.java:32) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:588) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612) at com.aaa.test.Send.main(Send.java:19)
2 、如果写错了HOST的IP（如：factory.setHost(“192.168.1.10”); ）无此地址， 报错：
Exception in thread “main” java.net.ConnectException: Connection timed out: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:213) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:200) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:529) at com.rabbitmq.client.impl.FrameHandlerFactory.create(FrameHandlerFactory.java:32) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:588) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612)
3、如果写错端口PORT（如：factory.setPort(5678);） 报错：
Exception in thread “main” java.net.ConnectException: Connection refused: connect at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:351) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:213) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:200) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:366) at java.net.Socket.connect(Socket.java:529) at com.rabbitmq.client.impl.FrameHandlerFactory.create(FrameHandlerFactory.java:32) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:588) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612) at com.aaa.test.Send.main(Send.java:19)
4、如果写错用户名或者密码，报错：
Exception in thread “main” com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile. at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:338) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:590) at com.rabbitmq.client.ConnectionFactory.newConnection(ConnectionFactory.java:612) at com.aaa.test.Send.main(Send.java:19)
5、解决方法
1.首先点击用户 图片:
2.点击自己注册的用户名 图片：
3.点击Set permission进行授权 图片：
嗯哼，完成！
