여러 IP 주소를 사용하고 동일한 포트를 실행하려고 합니다. 이는 다중 기술 및 전용 IP 주소에 적용됩니다.
내 네트워크 인터페이스는 다음과 같이 설정되어 있습니다.
ifcfg-eno1
ifcfg-eno1:0
ifcfg-eno1:1
ifcfg-eno1:2
ifcfg-eno1:3
그리고 IP 주소를 192.xxx.xxx.147,148,149,150으로 변경하세요.
ping을 하면 서버로 돌아가지만 multicraft를 사용하려고 하면 포트에 바인딩할 수 없습니다.
이것이 인터페이스입니다(각 인터페이스의 IP를 변경하면 됩니다).

답변1
동일한 머신에서 모두 동일한 포트를 사용하는 다중 다중 인스턴스를 허용하려면 각 인스턴스에 대해 특정 주소를 설정해야 합니다. 인스턴스가 이를 사용하도록 구성된 경우 0.0.0.0모든 인터페이스에 바인딩되며 다른 인스턴스는 바인딩할 수 없습니다.
예, 주소의 예:
## The daemon will listen on the following IP/port.
## 0.0.0.0 to listen on all available interfaces (all IPs). Note that
## you will have to use the "externalIp" setting below if you set this
## to 0.0.0.0 as the control panel needs to know where to connect.
ip = 192.xxx.xxx.147
port = 25465
192.xxx.xxx.147이 주소를 실제 주소로 변경해야 합니다 .
