解决MySQL无法远程连接的方法_MySQL
在远程主机上,我开启了mysql 服务,用 phpmyadmin 可以打开,比如说用户名为 root,密码为 123456。不过用 Mysql 客户端远程连接时却报了错误,比如 Mysql-Front 报了如下错误。
Access denied for user ‘root'@'121.42.8.33′(using password:YES)
比较奇怪,phpmyadmin 可以正常访问,而 Mysql-Front 为什么无法连接呢?可能的原因,应该就是 IP 限制了,phpmyadmin在连接时使用的是localhost,而我们访问页面才使用的远程主机的 IP,而 Mysql-Front 连接的是远程主机。
解决方法如下,我们需要新建一个用户,然后授予所有 IP 可以访问的权限就好啦。
在下面的 sql 语句中,username 即为用户名,password 为你要设置的密码:
CREATE USER 'username'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' WITH GRANT OPTION; CREATE USER 'username'@'%' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' WITH GRANT OPTION; CREATE USER 'username'@'localhost' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' WITH GRANT OPTION; CREATE USER 'username'@'%' IDENTIFIED BY 'password'; GRANT ALL PRIVILEGES ON *.* TO 'username'@'%' WITH GRANT OPTION;
通过执行以上语句,便创建了一个用户名为 username,密码为 password 的新账户,再用新账号登录,就可以连接成功啦。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

VS Code can run on Windows 8, but the experience may not be great. First make sure the system has been updated to the latest patch, then download the VS Code installation package that matches the system architecture and install it as prompted. After installation, be aware that some extensions may be incompatible with Windows 8 and need to look for alternative extensions or use newer Windows systems in a virtual machine. Install the necessary extensions to check whether they work properly. Although VS Code is feasible on Windows 8, it is recommended to upgrade to a newer Windows system for a better development experience and security.

VS Code can be used to write Python and provides many features that make it an ideal tool for developing Python applications. It allows users to: install Python extensions to get functions such as code completion, syntax highlighting, and debugging. Use the debugger to track code step by step, find and fix errors. Integrate Git for version control. Use code formatting tools to maintain code consistency. Use the Linting tool to spot potential problems ahead of time.

Running Python code in Notepad requires the Python executable and NppExec plug-in to be installed. After installing Python and adding PATH to it, configure the command "python" and the parameter "{CURRENT_DIRECTORY}{FILE_NAME}" in the NppExec plug-in to run Python code in Notepad through the shortcut key "F6".

VS Code extensions pose malicious risks, such as hiding malicious code, exploiting vulnerabilities, and masturbating as legitimate extensions. Methods to identify malicious extensions include: checking publishers, reading comments, checking code, and installing with caution. Security measures also include: security awareness, good habits, regular updates and antivirus software.
