mysql ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)

当您遇到MySQL错误2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)时，这通常表示客户端无法连接到本地运行的MySQL服务器。原因可能有：

1. **服务未启动**：MySQL服务器可能没有在您的系统上正确运行，或者服务没有被自动启动。检查服务是否正在运行，可以通过命令行（对于Linux或Windows）运行 `net start mysql` 或者 `sudo service mysql start`。

2. **防火墙阻止**：如果防火墙设置阻止了MySQL的连接，您需要确认防火墙规则是否允许从本机访问MySQL的默认端口（通常是3306）。

3. **网络问题**：检查您的计算机是否能够正常访问网络，包括TCP/IP连接。

4. **权限问题**：如果您尝试连接的是root账户，确保您的账户有正确的权限，并且尝试使用正确的用户名和密码。

5. **端口更改**：如果MySQL的配置文件中已经改变了默认的3306端口，确保客户端使用了正确的端口号。

6. **驱动问题**：在使用数据库连接库（如phpMyAdmin、Python的MySQLdb等）时，确认库是否正确配置了连接参数。
