<p>I had created a web-server file hello.go with below content:</p> <p>package main</p> <p>import (</p> <pre><code>&#34;fmt&#34; &#34;net/http&#34; </code></pre> <p>)</p> <p>func helloWorld(w http.ResponseWriter, r *http.Request){</p> <pre><code>fmt.Fprintf(w, &#34;Hello World&#34;) </code></pre> <p>}</p> <p>func main() {</p> <pre><code>http.HandleFunc(&#34;/&#34;, helloWorld) http.ListenAndServe(&#34;:8080&#34;, nil) </code></pre> <p>}</p> <p>When i am running as go run hello.go from putty.</p> <p>I am able to access server is running fine and able to access <a href="" rel="nofollow"></a>.</p> <p><em>How we can run web-server on background process?</em></p> <p><strong>When I can close the putty session or after logged out from putty I m unable to access to my web-server.</strong></p> <hr/>**评论:**<br/><br/>partkyle: <pre><p><code>go run</code> is useful for running things quickly, but it isn&#39;t the best method for deploying an application. You will want to run <code>go build</code> to create an executable file that you will run. This way, you won&#39;t have to recompile everytime you run your program. You will have to run <code>go build</code> every time there is a code change. </p> <p>As for keeping a process running, for a real production app you will want to look in to using an init system. Assuming you are using CentOS 7, that would be systemd by default. </p> <p>If you don&#39;t want to go that far, look in to using screen or tmux to keep it running in a shell when you log out. </p> <p>Sorry for the brevity of my reply and my lack of links, I&#39;m ok mobile now. All of this should be easily searchable on Google. </p> <p>Happy coding!</p></pre>Cabraca: <pre><p><a href="" rel="nofollow"></a></p> <p>This should do the trick</p></pre>Gambletron: <pre><p>You can also put Linux processes on a background thread by ending the command with &#39;&amp;&#39;. The caveat is that the process is still part of you putty shell, so when you close the shell it will close. And the useful command is &#39;nohup&#39; (no-hang-up)</p> <p>So if you&#39;re looking to boot it up one-time (<a href="/u/partkyle" rel="nofollow">/u/partkyle</a> mentioned adding it to init.d, which is the permanent solution), you can either <code>nohup git run &amp;</code> or build the exe and <code>nohup ./server &amp;</code></p></pre>
