Windows使用MONO在LINUX中进行服务开发？

Question

我刚刚从.net开发转移到LINUX MONO开发......我以前对linux开发人员有很多经验..

1. 我要求在单声道c#中创建后台服务(如Windows服务)..是否可能..

2. 是否可以从单声道c#访问LINUX本机API.(比如来自win c#的winAPI调用)..

Answer 1

我使用脚本,所以我可以捕获退出代码并使用它来执行自动更新和事情.如果它崩溃,它也会自动重启,并在用日志文件的最后x行重新启动时给你发电子邮件.

/etc/init.d/MyMonoApp

#!/bin/sh

APP_USER=mono

case "$1" in
  start)


        echo "Starting $APP_NAME"

        start-stop-daemon --start \
                          --background \
                          --make-pidfile \
                          --pidfile /var/run/$APP_NAME.pid \
                          --chuid $APP_USER \
                          --exec "$APP_PATH/$APP_NAME"
    ;;
  stop)

        echo "Stopping $APP_NAME"
                start-stop-daemon -o  --stop \
                --pidfile /var/run/$APP_NAME.pid

    ;;

    echo "Usage: /etc/init.d/$APP_NAME {start|stop}"
    exit 1

        else

注意:如果您使用init.d脚本关闭应用程序,它将终止进程,而不是发出信号干净关闭.

1. Mono附带一个名为mono-service的Windows Service兼容系统.

   • 用于服务的Unix字是守护进程.常规守护进程可以在/etc/init.d/中找到,并通过从/etc/rc.*目录中进行符号链接安装到它们应该运行的运行级别中.

2. 只需像往常一样使用p/invoke.您还可以查看其他一些基于单声道的简单项目(如Banshee)的源代码,了解它们在Linux上的调用方式.只需在google.com/codesearch上搜索banshee即可.
