How does ganache-cli specify listening ports and addresses

In view of how ganache-cli specifies the listening port and address, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Simulator ganache-cli is an essential tool for the development of ethernet smart contracts and decentralized applications (DApp). The following describes how to customize the listening port and address when starting ganache-cli.

Specify listening port

By default, ganache-cli listens on port 8545, and you can change this default behavior using the-p or-- port startup options. For example, the following command starts ganache-cli snooping on port 7878:

~ $ganache-cli-p 7878 specify the listening address

By default, the listening address of ganache-cli is 0.0.0.0, which means that this node can be accessed from any computer on the network where the emulator is located. You can change this default behavior by using the-h or-- host startup options. For example, the following command starts ganache-cli snooping at address 127.0.0.1 so that only applications on the local machine can access the emulation node:

~ $ganache-cli-h 127.0.0.1 specify both the listening address and the listening port

Use both the-h and-p startup options to set the listening address and port. For example, the following command starts ganache-cli snooping on port 7878 at address 127.0.0.1:

~ $ganache-cli-h 127.0.0.1-p 7878 this is the answer to the question about how ganache-cli specifies the listening port and address. I hope the above content can be of some help to you.
