RabbitMQ使用哪些端口?
默认端口是5672,可以在手册中找到答案。它在RABBITMQ_NODE_PORT
变量中定义。
https://www.rabbitmq.com/configure.html#define-environment-variables
如果有人在RabbitMQ配置文件中更改了端口,则数字可能会不同:
vi /etc/rabbitmq/rabbitmq-env.conf
询问 nmap 是否能够检测到它:
sudo nmap -p 1-65535 localhost
Starting Nmap 5.51 ( http://nmap.org ) at 2014-09-19 13:50 EDT
Nmap scan report for localhost (127.0.0.1)
Host is up (0.00041s latency).
PORT STATE SERVICE
443/tcp open https
5672/tcp open amqp
15672/tcp open unknown
35102/tcp open unknown
59440/tcp open unknown
哦,看,5672和15672
询问netstat能否看到它:
netstat -lntu
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:15672 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:55672 0.0.0.0:* LISTEN
tcp 0 0 :::5672 :::* LISTEN
噢,看,5672.
使用lsof查看端口:
eric@dev ~$ sudo lsof -i | grep beam
beam.smp 21216 rabbitmq 17u IPv4 33148214 0t0 TCP *:55672 (LISTEN)
beam.smp 21216 rabbitmq 18u IPv4 33148219 0t0 TCP *:15672 (LISTEN)
使用不同的计算机,使用nmap工具,查看5672端口是否开启:
sudo nmap -p 5672 10.0.1.71
Starting Nmap 5.51 ( http://nmap.org ) at 2014-09-19 13:19 EDT
Nmap scan report for 10.0.1.71
Host is up (0.00011s latency).
PORT STATE SERVICE
5672/tcp open amqp
MAC Address: 0A:40:0E:8C:75:6C (Unknown)
Nmap done: 1 IP address (1 host up) scanned in 0.13 seconds
尝试使用 Telnet 手动连接端口,5671 端口处于关闭状态:
telnet localhost 5671
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
尝试使用telnet手动连接端口,5672已开放:
telnet localhost 5672
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
检查防火墙:
sudo cat /etc/sysconfig/iptables
它应该告诉你哪些端口是开放的:
-A INPUT -p tcp -m tcp --dport 5672 -j ACCEPT
重新应用您的防火墙:
sudo service iptables restart
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: [ OK ]
