Background When developing Spring Cloud microservices, we cannot start multiple microservices at the same time due to limited local memory. What if we do? PS: For example, 10 microservices are running locally in the notebook's 8G memory, which is basically stuck. In order to achieve the development of an environment where you can tunnel to the cloud server without configuring the local environment. Solution 1. Simple application memory optimization For Java applications with insufficient memory, you can set VM options parameters in the application panel of IDEA - Xms128m - Xmx2

The concept of ssh tunnel can be roughly divided into three types: local port forwarding, remote port forwarding, and dynamic port forwarding. This article will let you thoroughly understand the command expressions of these three forwarding, so that you can flexibly use them to solve various special situations in life. If you are using tools such as mobaxterm, xshell, secureCRT, and putty, you can use them by simply configuring the visual interface directly. If you do not use tools, you can directly tunnel through commands through this tutorial.

The foreword is no stranger to intranet penetration. No matter you are Xiaobai or a developer, you need some intranet penetration services. If you buy a server yourself, you are worried about the low bandwidth (1M~10M is generally used by domestic host companies), which leads to poor penetration effect. Recently, bloggers have been paying attention to HCaaS in the online banking Internet public test. Due to the high bandwidth, If you build an intranet penetration in a container, the speed is ideal. This tutorial aims to build an intranet penetration using HCaaS in the simplest way. If you don't know about Frp intranet penetration, you can move to my earlier article, "The Sharp Tools for Intranet Penetration frp

This website shared the self built FRP intranet penetration free of charge. For Xiaobai, the client configuration is cumbersome. Today, we bring you a lightweight and powerful intranet penetration proxy server. It supports tcp and udp traffic forwarding, intranet http proxy, intranet socks5 proxy, and snappy compression, site protection, encrypted transmission, multiplexing, header modification, etc. Support web graphical management and integrate multi-user mode.

An intranet frp penetration service built with an idle AliCloud server has been running steadily for 100 days and is now open to the public for free. If you feel good, please reward me for server expenses. The intranet penetration FRP service can access the web services deployed in the intranet through a user-defined domain name, access the company's intranet machines through ssh, provide simple file access services externally, point-to-point intranet penetration, securely expose intranet services and other services, especially for machines behind the intranet or firewall, and provide tcp and udp services for the external network environment, For example, you can access the company through ssh at home

Earlier, I wrote an article that uses frp to achieve intranet penetration. Here I introduce another one, which is called Ngrok

Download address of open source project → https://github.com/fatedier/frp/releasesfrp It is a high-performance reverse proxy application that can be used for intranet penetration. It supports tcp, udp, http, and https protocols. The role of frp: use the machine behind the intranet or firewall to provide http or https services to the external network environment. For http, the https service supports domain name based virtual hosts and custom domain name binding, so that multiple domain names can share one
