Not able to create new account in geth for private ethereum blockchain

Question

I am not able to create a new account in geth. I entered into geth console using the following command:

geth attach http://127.0.0.1:8543

Output:

Welcome to the Geth JavaScript console!
instance: Geth/v1.8.18-stable-58632d44/linux-amd64/go1.10.4
 modules: eth:1.0 net:1.0 rpc:1.0 web3:1.0
> eth.accounts
[]

Now when I am trying to create a new account, I am facing error as mentioned below:

> personal.newAccount('seed')
Error: The method personal_newAccount does not exist/is not available

Answer 1

personal.newAccount() is not a default geth method. This method is of API used for geth. For this command to work, you will have to include the APIs while starting the Blockchain. Try this:

geth --datadir ./myDataDir --networkid 1114 console 2 --rpc --rpcport 8543 --rpcaddr 127.0.0.1 --rpccorsdomain "*" --rpcapi "eth,net,web3,personal,miner"

Now, you should be able to to create a new account

$ geth attach http://127.0.0.1:8543

> personal.newAccount('seed')
