ASP.NET Core RC2 as linux deamon

问题

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.

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  

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.

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

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

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

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

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

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

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

EDIT: 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.
