為什麼 bitcoin-cli 不知道 bitcoind 的工作目錄？

我有/ect/systemd/system/bitcoin.service以下內容，我想知道，為什麼bitcoin-cli getinfo告訴我其他地方的配置文件：

error: Could not locate RPC credentials. No authentication cookie could be found, and RPC password is not set.  See -rpcpassword and -stdinrpcpass.  Configuration file: (/home/pi/.bitcoin/bitcoin.conf)

的內容bitcoin.service，尤其是-conf=/home/bitcoin/.bitcoin/bitcoin.conf：

[Unit]
Description=Bitcoin daemon
After=network.target
[Service]
ExecStart=/usr/local/bin/bitcoind -conf=/home/bitcoin/.bitcoin/bitcoin.conf -pid=/home/bitcoin/.bitcoin/bitcoind.pid

RuntimeDirectory=bitcoind

bitcoin-cli必須以與 相同的方式user執行bitcoind。

否則它將檢查錯誤目錄中的配置文件，因為預設目錄是home執行該程序的使用者的目錄。

bitcoin-cli使用bitcoin-rpc，所以對於使用bitcoin-cli，你必須執行bitcoind的配置，如果沒問題，你可以使用bitcoin-cli獲取命令

一個簡單的文件配置可能是它

##
## bitcoin.conf configuration file. Lines beginning with # are comments.
##
# On client-side, you add the normal user/password pair to send commands:
rpcuser=alice
rpcpassword=bob

或者你可以執行bitcoind with this command bitcoind -rpcuser=alice -rpcpassword=bob
