A brief description of OTP in Erlang and a brief description of ErlangOTP OTP contains a set of libraries and implementation methods to build large-scale, fault-tolerant, and distributed applications. It contains many powerful tools to implement H248, SNMP, and other protocols, the core concept is OTP behavior. It can be seen as an application framework that uses

Kerl has only one goal: let's switch between different versions of the OTP. He is a pure bash project. Simple and practical work tool!The use of the Readme has been explained very clearly. It is recommended to follow the process once.1. DownloadInstall (a bash script that doesn't have to be installed at all)Curl-o https://raw.githubusercontent.com/kerl/kerl/master/kerlchmod a+x Kerl2.

Erlang OTP is a complete and reliable large-scale library, is a great success of the predecessors; now try the application inets Web server httpd, write a code call Inets service:1 -module(INETS_HTTPD). 2 -export([start/0]). 3 4 Start ()5 inets:start (),6 Inets:start (httpd, [{bind_ Address, {192,168,178,130}}, {ipfamily, inet}, {port, 18080}, {service_admin, "[Email protected]"}, {server_name, " Whyang.yang.net "}, {server_root,".

1> application: Start (log4erl ). Let's start with this command line. After you press enter, you can start the log4erl application. the component that can complete a specific set of functions in Erlang/OTP is called application ., application is one of the forms of Erlang code and function Organization ([Erlang 0015] Erlang OTP design principles ). application is designed to run one or more processes to com

The OTP contains a set of libraries and implementations that can build large-scale, fault-tolerant, and distributed applications, including many powerful tools to implement multiple protocols such as H248,SNMP, the core concept being the OTP behavior, which can be seen as an application framework with callback functions as parameters, similar to a Java EE container. Behavior is responsible for solving the n

hung, just restart the child process without affecting the other child Process), the only difference is that Simple_one_for_one can only dynamically add the child process and all the child process executes the same code, let's take a look at an example (from the official OTP document) Notice here that Startfunc: {call, Start_link, []} does not actually start a child process, but must dynamically add the child by calling Supervisor:start_child (Sup, L

In the OTP Introduction section of programming Erlang, the author shows us the Gen_server design ideas in a gradual manner, and now summarizes:Before we look at Gen_server, we'll look at a common server framework:In this server, you can hardly see anything related to a specific function, it only provides a basic framework that the server has, how does it work?When we call the start function, a service is started, and if the server receives a message,

Note: The original is from this Daniel The first time to write a blog article, inevitably there is a bug, writing this article purely to share experience with you, And then found that there are many such articles on the Internet, but, from my point of view, I was the Linux command, Bound to the corresponding IDE, plug-ins and so do not have direction, so I want to share my build process Relatively simple, in advance, this environment, after a good, big development should not be, However, it is s

Note that both nodes have successfully registered the global name A, because there is no connection between the two nodes. Once these two nodes are connected, Erlang/
