安装rabbitmq 之后可以通过默认的15672端口访问web界面进行管理，rabbitmq一些默认端口如下：
- 4369: epmd, a peer discovery service used by RabbitMQ nodes and CLI tools
- 5672, 5671: used by AMQP 0-9-1 and 1.0 clients without and with TLS
- 25672: used by Erlang distribution for inter-node and CLI tools communication and is allocated from a dynamic range (limited to a single port by default, computed as AMQP port + 20000). See networking guide for details.
- 15672: HTTP API clients and rabbitmqadmin (only if the management plugin is enabled)
- 61613, 61614: STOMP clients without and with TLS (only if the STOMP plugin is enabled)
- 1883, 8883: (MQTT clients without and with TLS, if the MQTT plugin is enabled
- 15674: STOMP-over-WebSockets clients (only if the Web STOMP plugin is enabled)
- 15675: MQTT-over-WebSockets clients (only if the Web MQTT plugin is enabled)
如果默认15672端口页面无法访问，先检查一下防火墙，添加端口或者关闭防火墙，centos6.5 关闭防火墙：
[root@localhost ~]#servcie iptables stop --临时关闭防火墙，重启后复原
[root@localhost ~]#chkconfig iptables off --永久关闭防火墙，重启后不会复原
[root@localhost ~]# service iptables status 查看防火墙状态
若关闭防火墙之后还是无法访问，则是由于在3.3.1和之后的版本，出于安全的考虑，guest这个默认的用户只能通过http://localhost:15672 登录，无法直接使用远程ip登录访问，需要进行配置，在配置之前先创建一个admin账号，并进行授权：
查看用户 ：rabbitmqctl list_users
创建一个admin用户：rabbitmqctl add_user admin admin
用户授权 ：rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_permissions -p / asdf ".*" ".*" ".*"
创建用户之后需要进行配置，若使用rpm安装，则修改配置/etc/rabbitmq/rabbitmq.config,配置内容大致如下：
[
{rabbit,
[%%
%% Network Connectivity
%% ====================
%%
%% By default, RabbitMQ will listen on all interfaces, using
%% the standard (reserved) AMQP port.
%%
{tcp_listeners, [5672]},
{loopback_users, ["admin"]}
]}
].
配置之后，如果rabbitmq无法正常启动，出现错误：
init terminating in do_boot () Crash dump is being written to: erl_crash.dump...done
此时有可能是配置文件配置有问题，确保配置文件没问题之后，重启即可。
