You can test whether the MySQL server is working by executing any of the following commands:您可以通过执行以下任意命令来测试MySQL服务器是否正常工作：

C:\> "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqlshow"
C:\> "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqlshow" -u root mysql
C:\> "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysqladmin" version status proc
C:\> "C:\Program Files\MySQL\MySQL Server 8.0\bin\mysql" test

If mysqld is slow to respond to TCP/IP connections from client programs, there is probably a problem with your DNS. 如果mysqld对来自客户端程序的TCP/IP连接的响应很慢，那么您的DNS可能有问题。In this case, start mysqld with the skip_name_resolve system variable enabled and use only localhost and IP addresses in the Host column of the MySQL grant tables. 在这种情况下，在启用skip_name_resolve系统变量的情况下启动mysqld，并仅使用MySQL授权表的Host列中的localhost和IP地址。(Be sure that an account exists that specifies an IP address or you may not be able to connect.)（请确保存在指定IP地址的帐户，否则您可能无法连接。）

You can force a MySQL client to use a named-pipe connection rather than TCP/IP by specifying the --pipe or --protocol=PIPE option, or by specifying . (period) as the host name. 通过指定--pipe或--protocol=PIPE选项，或者通过指定.（句点）作为主机名，可以强制MySQL客户端使用命名管道连接，而不是TCP/IP。Use the --socket option to specify the name of the pipe if you do not want to use the default pipe name.如果不想使用默认管道名称，请使用--socket选项指定管道名称。

If you have set a password for the root account, deleted the anonymous account, or created a new user account, then to connect to the MySQL server you must use the appropriate -u and -p options with the commands shown previously. See Section 4.2.4, “Connecting to the MySQL Server Using Command Options”.如果您已经为root帐户设置了密码，删除了匿名帐户，或者创建了新的用户帐户，那么要连接到MySQL服务器，您必须使用前面显示的命令使用相应的-u和-p选项。请参阅第4.2.4节，“使用命令选项连接到MySQL Server”。
