In the customer's intranet environment, ppoe is used to dial up the Internet. The provider is a secondary operator within the group. The network environment is relatively complex. The group's internal network and office network are interconnected using a static routing protocol. The general situation is as follows:
Originally, customers accessed production services through IP addresses. With the increasing number of production services, customers now strongly require the use of domain names to access services. However, given the complexity of the intranet environment, it is difficult to deploy a domain name server, and it is also difficult to deploy access services.
Later I learned nginx and learned that nginx can implement forward proxy to realize domain name forwarding.
Instructions:
1. Configure domain name resolution on Alibaba Cloud. For example, oa.xxxx.com, the resolved address is the intranet address 172.31.101.36
2, 172.31.101.36 is the VIP address, which is provided by two nginx configuration keepalived
3. The general access process is that the customer accesses the domain name, the domain name is resolved to the VIP intranet address, and the intranet nginx service forwards the domain name request to the designated intranet server
In order to complete the entire process, it must be ensured that the nginx server can be accessed External network, and can be connected to the designated production server network of the internal network. At the same time, the customer can resolve the domain name normally after dialing through PPO.
What needs to be explained is the configuration of nginx proxy forwarding. I use the sub-configuration method.
Create a new configuration file in the /application/nginx/conf/conf.d directory
vim oa.xxxxx.com.conf
Write as follows
After the configuration is completed, check the nginx syntax and restart the nginx process
/application/nginx/sbin/nginx -t /application/nginx/sbin/nginx -s reload
After the configuration is completed, check whether the domain name is valid
The above is the detailed content of How to use nginx forward proxy to forward intranet domain names. For more information, please follow other related articles on the PHP Chinese website!

NGINXUnit can be used to deploy and manage applications in multiple languages. 1) Install NGINXUnit. 2) Configure it to run different types of applications such as Python and PHP. 3) Use its dynamic configuration function for application management. Through these steps, you can efficiently deploy and manage applications and improve project efficiency.

NGINX is more suitable for handling high concurrent connections, while Apache is more suitable for scenarios where complex configurations and module extensions are required. 1.NGINX is known for its high performance and low resource consumption, and is suitable for high concurrency. 2.Apache is known for its stability and rich module extensions, which are suitable for complex configuration needs.

NGINXUnit improves application flexibility and performance with its dynamic configuration and high-performance architecture. 1. Dynamic configuration allows the application configuration to be adjusted without restarting the server. 2. High performance is reflected in event-driven and non-blocking architectures and multi-process models, and can efficiently handle concurrent connections and utilize multi-core CPUs.

NGINX and Apache are both powerful web servers, each with unique advantages and disadvantages in terms of performance, scalability and efficiency. 1) NGINX performs well when handling static content and reverse proxying, suitable for high concurrency scenarios. 2) Apache performs better when processing dynamic content and is suitable for projects that require rich module support. The selection of a server should be decided based on project requirements and scenarios.

NGINX is suitable for handling high concurrent requests, while Apache is suitable for scenarios where complex configurations and functional extensions are required. 1.NGINX adopts an event-driven, non-blocking architecture, and is suitable for high concurrency environments. 2. Apache adopts process or thread model to provide a rich module ecosystem that is suitable for complex configuration needs.

NGINX can be used to improve website performance, security, and scalability. 1) As a reverse proxy and load balancer, NGINX can optimize back-end services and share traffic. 2) Through event-driven and asynchronous architecture, NGINX efficiently handles high concurrent connections. 3) Configuration files allow flexible definition of rules, such as static file service and load balancing. 4) Optimization suggestions include enabling Gzip compression, using cache and tuning the worker process.

NGINXUnit supports multiple programming languages and is implemented through modular design. 1. Loading language module: Load the corresponding module according to the configuration file. 2. Application startup: Execute application code when the calling language runs. 3. Request processing: forward the request to the application instance. 4. Response return: Return the processed response to the client.

NGINX and Apache have their own advantages and disadvantages and are suitable for different scenarios. 1.NGINX is suitable for high concurrency and low resource consumption scenarios. 2. Apache is suitable for scenarios where complex configurations and rich modules are required. By comparing their core features, performance differences, and best practices, you can help you choose the server software that best suits your needs.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
