错误 2002 (HY000)：在运行 sudo mysql -e 时，无法通过套接字“/var/run/mysqld/mysqld.sock”连接到本地 MySQL 服务器”

Question

我在运行命令sudo mysql -e "SET Password=PASSWORD('rootpassword')"时收到此错误，请查看 ci.yaml 文件中的问题。

它说：-错误2002（HY000）：无法通过套接字'/var/run/mysqld/mysqld.sock'（2）连接到本地MySQL服务器

我正在将.travis.yml 文件转换为 ci.yml 文件，并在同一期间收到此错误

这是代码
