客户端无法连接到本地主机上的 RabbitMQ 服务器 [英] Client can't connect to RabbitMQ server on localhost
问题描述
我通过 apt-get 在 ubuntu 12.04.2 LTS 上安装了新的 RabbitMQ 3.1.3,并尝试在同一台服务器上启动消费者,但我有连接问题:
I installed fresh RabbitMQ 3.1.3 on ubuntu 12.04.2 LTS by apt-get, and try to start consumers on the same server, but I have connection problem:
[PhpAmqpLib\Exception\AMQPRuntimeException]
Error Connecting to server(113): No route to host
有工作服务器的状态:

...done.
我对 iptables(端口)没有任何限制:
I don't have any limitations by iptables (ports):
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
而且 etc/hosts
没问题.
127.0.0.1 localhost
{IP-ADDRESS} ns1.***.org ns1
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
我做错了什么?
更新:sudo netstat -nlp |grep 5672
返回:tcp6 0 0 ::::5672 ::* LISTEN 2106/beam.smp
来自rabbitMQ日志:
From rabbitMQ logs:
=INFO REPORT==== 2-Jul-2013::16:05:11 ===

=INFO REPORT==== 2-Jul-2013::16:05:11 ===

=INFO REPORT==== 2-Jul-2013::16:35:04 ===

我尝试将 localhost
更改为 ip6-localhost
有时尝试启动消费者时,它返回:
I tried to change localhost
to ip6-localhost
and sometimes when try to starting consumer, it returns:
[PhpAmqpLib\Exception\AMQPRuntimeException]
Error Connecting to server(110): Connection timed out
UPD2 如果我使用调试标志和 --env=prod
(php .../app/console rabbitmq:consumer -w -dconsumer_name
),消费者开始工作.
UPD2 If I start consumer with debug flag and --env=prod
(php .../app/console rabbitmq:consumer -w -d consumer_name
), consumer starts and working.
推荐答案
问题已修复,将侦听地址从 0.0.0.0:5672 重新配置为 127.0.0.1:5672,并在操作系统中进行了一些小的安全修复.
Problem was fixed with reconfiguring listen address from 0.0.0.0:5672 to 127.0.0.1:5672 and small security fixes in OS.
