问题
Hi I am new to blockchain topic and I am trying to make an Ethereum smart contract. First step I installed truffle and when I try to migrate it throws an error because I have no ethereum client. For solving this problem truffle develop, ganache, geth are recommended but I couldnt decide to which one is more suitable and I dont understand the difference of ganache and geth. Basically are they serving same thing or not? Here is error:
Could not connect to your Ethereum client with the following parameters:
- host > 127.0.0.1
- port > 7545
- network_id > *
Please check that your Ethereum client:
- is running
- is accepting RPC connections (i.e., "--rpc" option is used in geth)
- is accessible over the network
- is properly configured in your Truffle configuration file (truffle-config.js)

Truffle
As you already did, you migrated a contract. So Truffle can be used for contract compilation and migration. It aims for easy and fast migration.
Geth
Is an Ethereum-client, which means that you can run your own private blockchain with it. You can adjust your needs by defining for example the amount of threads you offer for mining. Geth itself is a command line tool, which can run a full Ethereum node implemented in Go. It provides the command lines, a Json-rpc server and an interactive console, where you can run your own scripts written in javascript.
Ganache
If you want a GUI, where you can track all deployments and transactions on your blockchain, you can choose Ganache. It allows you to create your own private blockchain mainly for testing purposes. It is used for deployment-testing for example, because there are no real miners on a "ganache-blockchain", so you can test if your contracts work.
I would suggest you to use Geth and Truffle if you want to set up your own blockchain on your local node and then deploy some contracts on it. There are plenty of manuals online on how to set up your own local node. For example:
- Create your own local node with geth
- Setting up Ethereum development environment
After you created your node, you can deploy some contracts with truffle to it. I hope I could help you.
