我正在尝试使用多个 IP 地址并运行相同的端口。这适用于 multicraft 和专用 IP 地址。
我的网络接口设置为：
ifcfg-eno1
ifcfg-eno1:0
ifcfg-eno1:1
ifcfg-eno1:2
ifcfg-eno1:3
并将 IP 地址更改为 192.xxx.xxx.147,148,149,150。
当我 ping 时，它确实返回到服务器，但当我尝试使用 multicraft 时，它无法绑定到端口。
这是接口（只是每个接口改变了ip）

答案1
允许在同一台机器上使用多个 multicraft 实例，所有实例都使用相同的端口，您需要为每个实例设置一个特定的地址。如果实例配置为使用0.0.0.0它将绑定到所有接口，并且任何其他实例将无法绑定。
一个实例，一个地址的示例：
## 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
请注意，您需要将其更改192.xxx.xxx.147为真实地址。
