安装 OpenStack 时无法连接到“127.0.0.1”（111）上的 MySQL 服务器

Question

我正在尝试在本地计算机上安装 openstack。我遵循以下文档：开发栈。安装过程因以下错误而中断：-

ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1' (111)

我也尝试过改变

bind-address = 127.0.0.1

到

bind-address = localhost

我也尝试重新启动 mysql 服务器，但仍然出现同样的错误。

错误：-

 + sudo mysql -uroot -pstackdb -h127.0.0.1 -e 'GRANT ALL PRIVILEGES ON *.* TO  
   '\''root'\''@'\''%'\'' identified by '\''stackdb'\'';'
