Centos 7 安装VNC步骤
VNC允许Linux系统可以类似实现像Windows中的远程桌面访问那样访问Linux桌面。本文配置机器是兴宁市网络信息中心的一台Centos 7 HP服务器环境下运行。
首先试试服务器装了VNC没
[root@wic ~]# rpm -q tigervnc tigervnc-server
没安装的话会直接出现
package tigervnc is not installedpackage tigervnc-server is not installed
如果没有安装X-Windows 桌面的话要先安装Xwindows
[root@wic ~]# yum check-update[root@wic ~]# yum groupinstall "X Window System"[root@wic ~]# yum install gnome-classic-session gnome-terminal nautilus-open-terminal control-center liberation-mono-fonts[root@wic ~]# unlink /etc/systemd/system/default.target[root@wic ~]# ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target[root@wic ~]# reboot
第一步,安装VNC packages:
[root@wic ~]# yum install tigervnc-server -y
第二步,修改配置信息,在/etc/systemd/system/下建立文件夹vncserver@:1.service 把example config 文件从/lib/systemd/system/vncserver@.service复制到里面
[root@wic ~]# cp /lib/systemd/system/vncserver@.service /etc/systemd/system/vncserver@:1.service
然后打开这个配置文件/etc/systemd/system/vncserver@:1.service替换掉默认用户名
找到这一行
ExecStart=/sbin/runuser -l <user> -c "/usr/bin/vncserver %i"PIDFile=/home/<user>/.vnc/%H%i.pid</user></user>
这里我直接用root 用户登录,所以我替换成
ExecStart=/sbin/runuser -l root -c "/usr/bin/vncserver %i"PIDFile=/root/.vnc/%H%i.pid
如果是其他用户的话比如john替换如下
ExecStart=/sbin/runuser -l <user> -c "/usr/bin/vncserver %i"PIDFile=/home/<user>/.vnc/%H%i.pid</user></user>
第三步,重加载systemd
[root@wic ~]# systemctl daemon-reload
第四步,为VNC设密码
[root@wic ~]# vncpasswd
第五步,由于我这边的Centos 7 是用iptable防火墙的所以
vim /etc/sysconfig/iptables
在合适位置加上
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5900:5903 -j ACCEPT
重启iptable
service iptables restart
如果是用Centos 7 默认防火墙的可能需要
[root@wic ~]# firewall-cmd --permanent --add-service vnc-server[root@wic ~]# systemctl restart firewalld.service
第六步,设默认启动并开启VNC
[root@wic ~]# systemctl enable vncserver@:1.service[root@wic ~]# systemctl start vncserver@:1.service
这样基本上Centos 端就设好了,Windows 端要去下一个VNC Viewer 的软件。连接一下试试看着有点简陋但是上去了的

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

Damn Vulnerable Web App (DVWA) is a PHP/MySQL web application that is very vulnerable. Its main goals are to be an aid for security professionals to test their skills and tools in a legal environment, to help web developers better understand the process of securing web applications, and to help teachers/students teach/learn in a classroom environment Web application security. The goal of DVWA is to practice some of the most common web vulnerabilities through a simple and straightforward interface, with varying degrees of difficulty. Please note that this software
