这是一个 MySQL 数据库连接错误,错误代码为 1045。它表示用户尝试使用错误的用户名或密码连接到 MySQL 数据库,并且连接被拒绝。在你给出的命令中,-uroot 意味着你正在尝试使用 root 用户名连接到 MySQL 数据库,-pGTMCmy123 意味着你正在尝试使用密码 GTMCmy123 进行身份验证。然而,MySQL 服务器拒绝了该用户在该主机上的连接,因为可能是用户名或密码不正确。此外,警告 "Using a password on the command line interface can be insecure." 意味着在命令行界面上使用密码可能是不安全的,因为密码可能会被记录在命令历史记录或其他日志文件中,从而导致安全问题。

引用中提到了解决Mysql登录验证错误的方法。首先,你可以停止Mysql服务并使用以下命令以跳过验证登录:`mysqld_safe --user=mysql --skip-grant-tables --skip-networking &`.然后,你可以使用以下命令登录到Mysql并修改root用户的密码:`UPDATE user SET Password=PASSWORD('newpassword') where USER='root' and host='root' or host='localhost';`接着,刷新权限并退出Mysql。最后,你需要重新启动Mysql服务,并使用新设置的密码登录Mysql。
引用中也提到了类似的问题解决方法。你可以通过修改配置文件和重启Mysql来解决该错误。首先,你需要修改Mysql的配置文件`/etc/my.cnf`,在文件中加入`skip-grant-tables`以跳过验证登录。然后,你需要重启Mysql服务。接下来,登录到Mysql并修改root用户的密码。最后,去掉配置文件中的`skip-grant-tables`字段并重新启动Mysql服务。
至于引用中提到的Mysql启动报PID错误,可以通过更改权限和运行`scripts/mysql_install_db`来解决。你可以使用`chown -R mysql.mysql .`更改Mysql文件夹的所有者。然后,切换到mysql用户并运行`scripts/mysql_install_db`来重新安装Mysql。
综上所述,解决1045-Access denied for user 'root'@'localhost'错误的方法包括跳过验证登录、修改密码、重启Mysql服务等操作。具体的步骤可以根据你的情况选择适合的方法进行尝试。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. chun
CORS stands for Cross-Origin Resource Sharing, and it is a security mechanism implemented by web browsers to protect users from malicious scripts. When a web page makes a request to a different domain, the browser checks if the server includes the 'Access-Control-Allow-Origin' header in its response. If the header is not present or does not match the origin of the requesting page, the browser blocks the request.
The error message you mentioned, "has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource," indicates that the server you are making a request to does not allow cross-origin requests from your domain. This can happen if the server is not configured properly or intentionally restricts access.
To fix this issue, you have a few options:
1. Modify the server's response headers: If you have control over the server, you can add the 'Access-Control-Allow-Origin' header to the response. This header should include the domain from which you are making the request or use "*" to allow requests from any domain. Here is an example of how to set this header in a server response:
```
Access-Control-Allow-Origin: https://your-domain.com
```
2. Use a proxy server: If you do not have control over the server's configuration or cannot modify it, you can set up a proxy server that acts as an intermediary between your web page and the target server. The proxy server can make the request on behalf of your page, and since the request will be from the same origin as your page, it will not be blocked by CORS restrictions.
3. Utilize JSONP or CORS workaround techniques: JSONP (JSON with Padding) is an older technique that allows cross-origin requests by loading scripts instead of making XMLHttpRequests. However, it has some limitations and potential security risks. Alternatively, some servers may provide specific workarounds or APIs that bypass CORS restrictions. You can check the server's documentation or contact the server owner to see if there are any alternative methods available for making cross-origin requests.
Remember, the specific solution will depend on your server's configuration and the requirements of your application.
