通过Alias来修改phpMyAdmin的默认访问路径
?
phpMyAdmin的配置文件phpMyAdmin.conf文件位于/etc/httpd/conf.d/目录下,所有位于/etc/httpd/conf.d/目录中的配置文件都是httpd的子配置文件,任何一个子配置文件的语法错误都可能导致httpd启动失败。
?
[[email protected]]#?httpd?-t????//该命令可用于检查与httpd相关的配置文件的语法是否正确
?
phpMyAdmin的web访问方式:
phpMyAdmin.conf中的Alias行决定了phpMyAdmin的web访问路径:
[[email protected]]#?cat?/etc/httpd/conf.d/phpMyAdmin.conf
#?phpMyAdmin?-?Web?based?MySQL?browser?written?in?php
#
#?Allows?only?localhost?by?default
#
#?But?allowing?phpMyAdmin?to?anyone?other?than?localhost?should?be?considered
#?dangerous?unless?properly?secured?by?SSL
?
#Alias?/phpMyAdmin?/usr/share/phpMyAdmin
#Alias?/phpmyadmin?/usr/share/phpMyAdmin
Alias?/nima/shangbuqi??/usr/share/phpMyAdmin
?
???Order?Deny,Allow
???Deny??from?All
???Allow?from?127.0.0.1
???Allow?from?192.168.18.0/24
???Allow?from?192.168.1.0/24
???Allow?from?::1
?
Alias?/nima/shangbuqi??/usr/share/phpMyAdmin表明phpMyAdmin的web访问路径为:
www.mydomain.com/nima/shangbuqi
?
下面的Deny与Allow表示允许那些主机访问phpMyAdmin,Order的顺序是"Deny,Allow",表示禁止所有IP访问,除了接下来Allow?from中定义的主机外。
?
注:/nima/shangbuqi是个虚拟路径,在服务器上没有该目录,httpd.conf中定义的web服务器根目录下更不会有该目录。
?
?
如果在phpMyAdmin的登陆页面中示:"Cannot?load?mcrypt?extension.?Please?check?your?PHP?configuration.",则表明服务器没有安装php-mcrypt包。
?
完了以后重启 service httpd restart

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
