安装magento2.4.3, mysql报错

执行命令:php bin/magento setup:install --base-url=http://mg2.localhost --base-url-secure=https://mg2.localhost --db-host=localhost --db-name=magento2 --db-user=magento2 --db-password='bIVVp4wM' --admin-firstname=dylan --admin-lastname=wang [email protected] --admin-user=admin --admin-password=1vrf4_3S --language=en_US --currency=USD --timezone=America/Chicago --use-rewrites=1 --search-engine=elasticsearch7 --elasticsearch-host=localhost --elasticsearch-port=9200

报错信息:SQLSTATE[HY000] [2002] No such file or directory

localhost换成127.0.0.1的话会变成:SQLSTATE[HY000] [2002] Connection refused
