ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost:3306’(10061)

ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost:3306’(10061) 这个错误提示表明无法连接到MySQL服务器。可能的原因是MySQL服务器没有运行，连接设置不正确或者防火墙阻止了连接。解决此问题的三个步骤如下：
1. 第一步，确保MySQL服务器正在运行。你可以通过检查MySQL服务状态来确认。你可以使用以下命令来检查服务状态：

   systemctl status mysql

如果MySQL服务正在运行，那么你应该看到"active (running)"的输出。如果服务没有运行，你可以使用以下命令启动MySQL服务：

   systemctl start mysql

2. 第二步，检查连接设置。请确保你使用的是正确的主机名和端口号。默认情况下，MySQL服务器使用本地主机和端口号3306。如果你使用的是不同的主机名或者端口号，请确保你在连接字符串中正确指定了它们。

3. 第三步，检查防火墙设置。防火墙可能会阻止你的MySQL服务器连接。你可以尝试暂时禁用防火墙来解决这个问题。具体的步骤取决于你使用的操作系统和防火墙软件。

ERROR 2003 HY000: Can't connect to MySQL server on 'localhost:3306' 10061 是一个MySQL数据库连接错误。这个错误表示无法连接到MySQL服务器。通常，这个错误是由于以下几个原因之一引起的：
1. MySQL服务器没有正确启动。
2. MySQL服务器的端口号不正确。
3. 防火墙或网络设置阻止了与MySQL服务器的连接。
4. MySQL服务器配置文件中的配置错误。
对于解决这个错误，你可以尝试以下几个步骤：
1. 确保MySQL服务器已经正确启动。你可以尝试通过命令行或者服务管理工具来启动MySQL服务器。
2. 检查MySQL服务器的端口号是否正确。默认情况下，MySQL服务器使用3306端口。如果你的MySQL服务器使用了其他端口，你需要相应地进行配置。
3. 检查防火墙或网络设置，确保允许与MySQL服务器的连接。你可以尝试暂时关闭防火墙来验证是否是防火墙导致的问题。
4. 检查MySQL服务器的配置文件，确保配置正确。特别是检查bind-address选项是否正确设置为允许连接的IP地址。
如果你尝试了以上步骤仍然无法解决问题，你可能需要进一步检查网络配置、MySQL服务器日志以及相关的错误信息来找出问题的具体原因。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

ERROR 2003 (HY000): Can t connect to MySQL server on localhost:3306 (10061)

This error message indicates that the MySQL server is not running or is not accessible on the specified port (3306) on the local machine. Possible causes of this error include:

1. The MySQL server is not running: You need to start the MySQL server by running the appropriate command for your operating system.

2. The MySQL server is running on a different port: Check if the MySQL server is running on a different port by looking at the configuration file.

3. Firewall or security software blocking the connection: Check if there is any firewall or security software that is blocking the connection to the MySQL server.

4. Incorrect MySQL server credentials: Check if you have provided the correct username and password to connect to the MySQL server.

5. Incorrect hostname or IP address: Check if you have provided the correct hostname or IP address to connect to the MySQL server.

To resolve this error, you should first check if the MySQL server is running and accessible on the specified port. If the server is running and accessible, then you should check for any firewall or security software that may be blocking the connection to the server. If you are still unable to connect, then you should check if you have provided the correct credentials, hostname or IP address.
