这个错误通常表示无法连接到 MySQL 服务器。可能有几个原因导致这个错误:
1. MySQL 服务器未启动:请确保 MySQL 服务器已经正确地安装并且正在运行。你可以尝试在命令行中运行 `mysql.server start` 或者 `service mysql start` 来启动服务器。
2. 主机名或端口号错误:请检查你的连接字符串中的主机名和端口号是否正确。默认情况下,MySQL 服务器的主机名是 `localhost`,端口号是 `3306`。如果你使用的是不同的主机名或端口号,请相应地修改连接字符串。
3. 防火墙阻止连接:防火墙可能会阻止对 MySQL 服务器的连接。确保防火墙允许从本地主机连接到 MySQL 服务器的端口。你可以尝试禁用防火墙或者配置防火墙规则以允许 MySQL 的连接。
4. MySQL 配置错误:检查 MySQL 服务器的配置文件,确保它已正确地配置为监听指定的主机和端口。你可以尝试编辑配置文件(通常位于 `/etc/mysql/my.cnf` 或 `/etc/my.cnf`)来进行必要的更改。
请根据具体情况逐一排查以上可能的原因,并确保你的 MySQL 服务器能够正常运行和接受连接。
