在Linux下实现Mysql远程访问
步骤一 激活Mysql配置文件my.cnf中的远程访问 位置: /etc/mysql/my.cnf (Debian linux) /etc/my.cnf (Red Hat Linux/Fedora Linux) /var/db/mysql/my.cnf (FreeBSD) 用VI打开,查找到bind-address这项,默认情况是127.0.0.1 把他注释掉,或者改成数据库主
步骤一 激活Mysql配置文件my.cnf中的远程访问
位置:
/etc/mysql/my.cnf (Debian linux)
/etc/my.cnf (Red Hat Linux/Fedora Linux)
/var/db/mysql/my.cnf (FreeBSD)
用VI打开,查找到bind-address这项,默认情况是127.0.0.1
把他注释掉,或者改成数据库主机所在IP地址。
比如?bind-address = 65.212.65.12
步骤二 授权帐户具有远程访问属性
首先登陆在数据库所在Linux上用Root权限登陆Mysql。
use mysql; select host, user from mysql;
正常情况下是只有三个root用户,他们的host分别是
- 127.0.0.1
- ::1
- localhost
如果我们其中127.0.0.1改为我们所需要的ip地址,比如:218.51.21.21,那么用这台IP的机子就能实现远程登陆mysql进行管理。这里要用到用户授权的语法。
grant all on *.* to username@’ip’ identified by “password”;
由此我们就可以新建一个超级管理员的帐户:
mysql > grant all privileges on *.* to admin@localhost identified by '123456' with grant option; mysql > grant all privileges on *.* to admin@'%' identified by '123456' with grant option;
其中第二句中’%'表示通配符,任何IP都能通过admin帐户远程访问mysql。
建立好之后我们再看看
select host, user from user;
是不是发现有两个新的用户名是admin,这时我们就可以开启远程访问了。

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

Although Notepad cannot run Java code directly, it can be achieved by using other tools: using the command line compiler (javac) to generate a bytecode file (filename.class). Use the Java interpreter (java) to interpret bytecode, execute the code, and output the result.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.
