SHOW GRANTS FOR 'hive'@'localhost'; bash: SHOW: 未找到命令

`SHOW GRANTS` 并不是一个在命令行中执行的命令,而是在 MySQL 或 MariaDB 中使用的 SQL 命令。
要查看用户 `hive` 在本地主机上的授权信息,需要在 MySQL 或 MariaDB 中执行以下命令:
```
SHOW GRANTS FOR 'hive'@'localhost';
```
需要确保已经以具有足够权限的用户身份登录到 MySQL 或 MariaDB 中。

ERROR 1045 (28000): Access denied for user hive @ localhost (using password: YES)
这个错误通常意味着你正在尝试使用一个没有权限的用户和密码连接到MySQL数据库。你需要检查以下几点:
1. 确认你正在使用正确的用户名和密码。如果你不确定,可以尝试使用root用户登录(如果你有root权限),或者联系数据库管理员获得正确的用户名和密码。
2. 确认你的用户在MySQL数据库中具有正确的权限。你可以使用以下命令检查用户的权限:
```
SHOW GRANTS FOR 'hive'@'localhost';
```
如果用户没有访问数据库的权限,你需要使用管理员用户(如root)的权限授予该用户访问数据库的权限。
3. 确认MySQL服务器正在运行,并且你正在使用正确的端口进行连接。你可以尝试使用以下命令检查MySQL服务器是否正在运行:
```
systemctl status mysqld
```
如果MySQL服务器没有运行,你需要启动它。如果MySQL服务器正在运行,你可能需要检查你的连接字符串中的端口号是否正确。
如果你已经检查了以上几点,仍然无法解决问题,那么你可能需要联系数据库管理员或MySQL社区获得更多的帮助。
mysqladmin:connect to server at 'localhost' failed error :'Access denied for user'root'@'::1'(using password:NO)')
This error message indicates that the MySQL admin tool (mysqladmin) was unable to connect to the MySQL server running on the local machine (localhost) using the root user account. The error message suggests that the root user account is not authorized to connect from the IPv6 loopback address (::1) without a password.
To resolve this issue, you can try the following steps:
1. Check that the MySQL server is running and accepting connections. You can use the command "systemctl status mysql" (on Linux) or "netstat -an | grep 3306" to verify this.
2. Check that the root user has the correct privileges to access the MySQL server. You can use the command "sudo mysql -u root -p" to log in to the server as root and run the command "show grants for 'root'@'localhost';" to check the privileges.
3. If the root user does not have the correct privileges, you can grant them using the command "GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;"
4. If the root user has the correct privileges, but you are still unable to connect, you may need to specify a password in the mysqladmin command. Use the command "mysqladmin -u root -p" and enter the root user password when prompted.
5. If you are still unable to connect, you may need to check the MySQL server logs for any error messages or consult the MySQL documentation for further troubleshooting steps.
