AccountsとPrivate Keysを初期状態で固定するには、-d optionをつけて起動

# ganache -d

(2) データの永続化のディレクトリ作成

# mkdir /opt/ganache/
# mkdir /opt/ganache/db

(3) データの永続化
–dbでsaveディレクトリを指定

# ganache --db /opt/ganache/db

３． データの永続化の確認

# cd /opt/ganache/db
# pwd
/opt/ganache/db
# ls
000003.log  CURRENT  LOCK  LOG  MANIFEST-000002
#
