rabbitmq使用报错总结
最近公司重构服务器架构,需要用到rabbitmq,在公司搞了一个下午还是连接不上,后来细看了英文说明,测试连接成功,得出如下报错几点。
我用的安装包:otp_win64_21.3.exe(erlang vm)和rabbitmq-server-3.7.13.exe ,最后测试成功。
连接的代码片段如下
com.rabbitmq.client.ConnectionFactory factory = new com.rabbitmq.client.ConnectionFactory();
factory.setHost("localhost");
factory.setPort(5672);
factory.setUsername("guest");
factory.setPassword("guest");
默认安装好rabbitmq就有服务(windows服务 IP:5672),或者中间代理(IP:5672),也有web监控(IP:15672);
默认的端口就是5672,用户guest密码guest,但这个用户名只能在本机访问,如果要网络访问,需要做用户管理;
1、如果写错了host (如:factory.setHost("locathost"); )报错:
Exception in thread "main" java.net.UnknownHostException: locathost
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
3、如果写错端口PORT(如:factory.setPort(5678);) 报错:
Exception in thread "main" java.net.ConnectException: Connection refused: connect
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.
