How to import an account in private ethereum network

Question

I have created a new ethereum account using the following command: 

geth --datadir ./datadir account new

This was successful. Next, I created the genesis file with the account ID and allocated ethers to it. I initiated the genesis block and started the peer node.

All these steps were successful, I found no problem. 

But when I check the accounts, it shows not account.

> eth.accounts

[]

Why is this happening?

Answer 1

 When you create a new account, the data related to that account is stored in the UTC file. 

When you check the accounts from the geth console, it lists the details of accounts present in the ./data/keystore directory.

In your case, you have first created the account and then initialized the peer node which means the details of the newly created account is in the ./datadir(path mentioned in your command in the question) and not in the  ./data/keystore directory.

Copy the file from  ./datadir to ./data/keystore directory and then you will be able to see the account.
