Docker error : MySQLdb._exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")
我正在尝试通过 docker-compose up
启动服务器
我收到一个错误：
MySQLdb._exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)")
但我可以使用以下命令连接到 mysql
docker exec -it containername mysql -uroot -p
docker-compose.yml
version: '3.1'
services:
db:
image: mysql
command: --default-authentication-plugin=mysql_native_password

DE 配置：
from flask_mysqldb import MySQL,MySQLdb
app = Flask(__name__)
app.config['MYSQL_HOST'] = 'localhost'

app.config['MYSQL_PASSWORD'] = '****'
app.config['MYSQL_DB'] = 'emp'
app.config['MYSQL_CURSORCLASS'] = 'DictCursor'
mysql = MySQL(app)
谁能帮我解决这个问题。谢谢大家
