ASP.NET Core RC2作为Linux守护进程 [英] ASP.NET Core RC2 as linux deamon

问题描述

我需要有关作为Linux守护程序托管网络核心控制台或asp.net应用程序的信息。 Microsoft.Hosting.WindowsService已经支持将应用程序作为Windows Service托管，但是我需要Linux守护程序类似的东西。

I need information about hosting of net core console or asp.net application as linux deamon. Hosting application as Windows Service is already supported by Microsoft.Hosting.WindowsService, but I need something similar for linux deamons.

推荐答案

I在RHEL上运行，因此选择编写自己的systemd单元文件。这是我与PostgreSQL结合使用的一个示例（因此环境变量）。我出于明显的原因删除了敏感信息。

I'm running on RHEL, and therefore have chosen to write my own systemd unit files. Here is an example of one I use in conjuction with PostgreSQL (hence the Environment variable). I've stripped out sensitive information for obvious reasons.

[Unit]  
Description=My Sample Application  
Documentation=  


Wants=network.target  
After=network.target  


[Service]  
User=dotnetuser  
Group=dotnetuser  
Nice=5  
KillMode=control-group  
SuccessExitStatus=0 1  
Environment=MY_CONNSTRING=Server=localhost;Username=myUser;Password=myPass;Database=myDatabase  


NoNewPrivileges=true  
PrivateTmp=true  
InaccessibleDirectories=/sys /srv -/opt /media -/lost+found  
ReadWriteDirectories=/var/www/myapp  
WorkingDirectory=/var/www/myapp  
ExecStart=/opt/dotnet/dotnet run  


[Install]  
WantedBy=multi-user.target  

文件位于 / etc / systemd / system 目录，并以其后的 .service命名服务名称。例如，完整路径可能是 /etc/systemd/system/aspnet-example.service 。

The file goes in the /etc/systemd/system directory and is named whatever you'd like to name the service with ".service" after it. For example, the full path might be /etc/systemd/system/aspnet-example.service.

您然后可以使用 systemctl start aspnet-example 和 systemctl stop aspnet-example 启动和停止服务。

You could then start and stop the service with systemctl start aspnet-example and systemctl stop aspnet-example.

要将服务设置为在启动时启动： systemctl启用aspnet-example

To setup the service to start at boot: systemctl enable aspnet-example

在配置文件中要指出的主要内容是：

The main things to point out in the configuration file are:

• 用户和组不应是root用户。我建议您让一个新用户运行您的应用程序。

• User and Group should NOT be root. I advise making a new user under which your applications run.

KillMode = control-group已设置为将SIGTERM发送到所有的dotnet进程，服务运行。

KillMode=control-group is set so that a SIGTERM is sent to all dotnet processes under which the service is run.

ReadWriteDirectory和WorkingDirectory指向Web应用程序的根目录。我以 / var / www / myapp 为例。

ReadWriteDirectory and WorkingDirectory point to the root of your web application. I've used /var/www/myapp as an example.

ExecStart必须是绝对值dotnet二进制文件的路径。 Systemd不支持相对路径。

ExecStart must be an absolute path to the dotnet binary. Systemd doesn't support relative paths.

编辑：我忘了提到的一件事是，我通常以以下方式运行nginx：在我的应用程序前面的反向代理。我提供了一个链接，其中包含有关发布到Linux生产服务器的更多信息。

One thing I forgot to mention is that I generally run nginx as a reverse proxy in front of my applications. I've included a link which has more information about publishing to a Linux production server.
