Not able to deploy smart contract to private network

Question

I am trying to deploy a smart contract. I have written the smart contract. To start the network, I used the following command.

geth --datadir="./dataDir" --port 30303 --rpc --rpcport 8545 --rpcaddr localhost --networkid 1114 --rpccorsdomain="*" --rpcapi "eth,web3"

then I run ’truffle deploy', I get the message:

Error deploying SimpleStorage:
Account does not exist or account balance too low Deploy failed.

Answer 1

This could happen due to 3 possible reasons.

1. No account created

Solution: Create an account.

> personal.newAccount('<Enter seed phrase here>')

2. Account is locked

Solution: Unlock the account using the following command in geth console

personal.unlockAccount("<account_address>")

Enter the password when asked

3. Not enough ethers in account. 

Solution: Add more ethers, you can do this by mining.
