How to build a .NET Core2.0+Nginx+Supervisor environment under Centos7 system

1. Introduction to linux.netcore. For a long time, Microsoft has only provided .net support for its own platform. This means that support for this "theoretically" cross-platform framework on Linux and macos can only be provided by third-party projects (such as mono. net). Until Microsoft launched .netcore, which is completely open source. This open source platform is compatible with .netstandard and provides fully consistent APIs on windows, linux and macos. Although this compact .net framework is only a subset of standard .net, it is already quite powerful. On the one hand, this small framework allows certain functional applications to run on three platforms at the same time (just like some functional

How to configure pathinfo mode in nginx

The reason is that I haven’t used Apache for a long time, and I gradually feel unfamiliar with Apache, because my friend has a zendframework framework that was moved from Apache to nginx and requires pathinfo mode support. So I started searching online for articles related to nginx+pathinfo. I thought it would be easy to configure it at first. After searching, I found that there are a lot of articles introducing nginx to enable pathinfo mode, and it seems that it is not difficult. But after several hours, it is still not configured properly. And the contents of a large number of articles are very similar, and they are basically reprinted. Starting to get a little anxious! Because one day has passed and the preparation has not been completed. There is no solution to continue groping, so continue searching. For the convenience of verification, I use a.c

How to implement port forwarding with nginx

Usage scenario 1. There is a server port in the intranet that needs to be mapped to the external network (for example, the external network server applies for a domain name, and then makes a nignx configuration for the domain name, and then needs to access an intranet http service in the configuration) ) 2. The intranet server does not have access rights to the external network. Only one server in the entire intranet has access to the external network, which can be used to penetrate the internal network of the curve-saving version. 3. The virtual machine only has a NAT network, and the virtual machine is only equipped with an internal network. localhost is forwarded to the host machine localhost. At this time, if you want to access the virtual machine port from the external network or other intranets (non-host machine) 4. Use the agent machine as a bastion machine (springboard machine) to prevent the internal system from being accessed at will. This When the bastion machine is configured with port forwarding, access through the bastion machine

Linux installation nginx server example code analysis

nginx relies on some software libraries. Before installation, please make sure that the system has software such as gcc, ssl, pcre, and gzip installed. You can use the rpm-q command to check whether the software is installed. [root@redhat1~]#rpm-qgccgcc-4.1.2-44.el5 The dependent library information is as follows: (1). The gzip module requires the zlib library (2). The rewrite module requires the pcre library (3). The ssl function requires the openssl library If you want to install pcre, download pcre to the destination directory. The version selected here is pcre-8.38. After downloading, perform the following operations tar-zxvfpcre-8.38.tar.gzcdpcre-

How to set up Referer in Nginx to prevent image theft

If the server's pictures are hotlinked by other websites, it will affect the server's bandwidth and access speed. At this time, we need to set the anti-hotlink function of the image file or video file; the anti-hotlink function simply means that you can directly access the resource. , but you cannot put my resource links on your own server for others to access, especially large files such as pictures or videos, which can easily cause the server to respond slowly. If it were not a picture host, I would really be afraid that other websites would directly use the pictures from this site. This kind of traffic is likely to be wiped out all at once. After all, CDNs are bought with free money. Therefore, it is better to set up an anti-hot link, nginx can complete this function. Generally speaking, browsers that comply with the http protocol will access the website from a website.

How Nginx uses Let's Encrypt to encrypt https

HTTPS is now the standard for websites. Many services must use https. If you don't use it, the browser may not be very friendly to you. If you don’t want to use a commercial CA key, you can use Let’s Encrypt for encryption. The only disadvantage of using Let’s Encrypt is that it needs to be updated every 3 months. Of course, you can also use automatic updates to handle it. We need to install the plug-in to achieve: obtain the pem key required for SSL encryption. Set certbot to automatically update the secret key. Required prerequisites: Nginx has been installed and the virtual host has been configured. Python has been installed.

Nginx build https server instance analysis

Introduction to https https (hypertexttransferprotocoloversecuresocketlayer) is an http channel aimed at security. Simply put, it is a secure version of http. That is, an SSL layer is added under http. The security foundation of https is SSL, so the details of encryption require SSL. It is a urischeme (abstract identifier system) with a syntax similar to the http: system and is used for secure http data transmission. The default port used by https is 443. SSL Certificate Certificate Type Introduction To set up a secure server, create a public and private key pair using the public key. In most cases, sending a certificate request (packaging

How to configure nginx ingress speed limit

Starting from the business scenario, during the business development process, we have a requirement: the download service provided through filebrowser needs to be speed limited. For example, when users download files through filebrowser, they need to limit the download rate of each user. Extending from this requirement, the download rate for specific users can also be limited. In order to realize this business requirement, combined with our current technology stack (k8s+nginxingress), it can be achieved by configuring the corresponding nginx parameters. What is a speed limit? Speed limit, as the name suggests, limits the rate. The rate here can be: the frequency with which a single user accesses resources in unit time, or the frequency with which a single IP accesses resources in unit time, or
