通过服务运行 go app

Question

在 CentOS 6.8 中，我有一个 golang 应用程序，它在命令中运行，go run main.go我需要创建一个系统服务来像服务 httpd 一样在启动时运行它。
我知道我必须创建文件，/etc/rc.d/init.d/httpd但我不知道如何运行该命令。

首先，您需要构建您的 Go 二进制文件并将其放入您的路径中。go install main.go如果您的“主”文件名为 main，go install则会在您的路径中放置一个名为“main”的二进制文件，因此我建议您将文件重命名为您的项目/服务器。mv main.go coolserver.gogo install coolserver.go您可以运行coolserver以确保一切正常。如果你的 $GOPATH 设置正确，它就会出现。这是一个名为的 init.d 服务示例service.sh#!/bin/sh### BEGIN INIT INFO# Provides:&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <NAME># Required-Start:&nbsp; &nbsp; $local_fs $network $named $time $syslog# Required-Stop:&nbsp; &nbsp; &nbsp;$local_fs $network $named $time $syslog# Default-Start:&nbsp; &nbsp; &nbsp;2 3 4 5# Default-Stop:&nbsp; &nbsp; &nbsp; 0 1 6# Description:&nbsp; &nbsp; &nbsp; &nbsp;<DESCRIPTION>### END INIT INFOSCRIPT=<COMMAND>FLAGS="--auth=user:password"RUNAS=<USERNAME>PIDFILE=/var/run/<NAME>.pidLOGFILE=/var/log/<NAME>.logstart() {&nbsp; if [ -f /var/run/$PIDNAME ] && kill -0 $(cat /var/run/$PIDNAME); then&nbsp; &nbsp; echo 'Service already running' >&2&nbsp; &nbsp; return 1&nbsp; fi&nbsp; echo 'Starting service…' >&2&nbsp; local CMD="$SCRIPT&nbsp; $FLAGS &> \"$LOGFILE\" & echo \$!"&nbsp; su -c "$CMD" $RUNAS > "$PIDFILE"&nbsp; echo 'Service started' >&2}stop() {&nbsp; if [ ! -f "$PIDFILE" ] || ! kill -0 $(cat "$PIDFILE"); then&nbsp; &nbsp; echo 'Service not running' >&2&nbsp; &nbsp; return 1&nbsp; fi&nbsp; echo 'Stopping service…' >&2&nbsp; kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE"&nbsp; echo 'Service stopped' >&2}uninstall() {&nbsp; echo -n "Are you really sure you want to uninstall this service?

我假设您尝试使用 apache Web 服务器。实际上，Go Web 服务器本身就足够了。主要目的是在系统服务中运行 Go Web 服务器。因此，您可以使用tmux&nbsp;https://tmux.github.io/或nohup作为系统服务运行。您还可以使用 apache 或 nginx Web 服务器作为代理。
