RabbitMQ 使用哪些端口?
默认值:5672,手册有答案。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 配置文件中更改该数字可能会有所不同:
vi /etc/rabbitmq/rabbitmq-env.conf
询问 nmap 是否可以看到:
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 是否可以看到:
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
哦,看 5672。
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)
使用另一台机器上的 nmap,查看 5672 是否打开:
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 已关闭:
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 已打开:
telnet localhost 5672
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
检查您的防火墙:
sudo cat /etc/sysconfig/iptables
它应该告诉您打开了哪些端口:
-A INPUT -p tcp -m tcp --dport 5672 -j ACCEPT
重新应用防火墙:
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 ]
