linux - 服务文件未在 Ubuntu 上运行，但项目/文件在 Putty/终端上运行良好(ASP.NET Core 网站)

Question

当我在 Ubuntu 20.04 中从 Putty 运行 ASP.NET Core 网站时:

/usr/bin/dotnet /root/dev/myWebApp/myWebApp/myWebApp.dll

或者

dotnet /root/dev/myWebApp/myWebApp/myWebApp.dll

它可以在浏览器上正常运行网站: localhost:5000或 https://localhost:5001但是当我尝试使用以下命令将其作为服务“website.service”启动时:

sudo nano /etc/systemd/system/website.service

并写入文件:

[Unit]
Description=Example .NET Web API App running on Ubuntu

[Service]
WorkingDirectory=/root/dev/myWebApp/myWebApp
ExecStart=/usr/bin/dotnet /root/dev/myWebApp/myWebApp/myWebApp.dll
Restart=always
# Restart service after 10 seconds if the dotnet service crashes:
RestartSec=10
KillSignal=SIGINT
SyslogIdentifier=dotnet-example
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

[Install]
WantedBy=multi-user.target

接着:

sudo systemctl enable website.service
sudo systemctl daemon-reload
sudo systemctl start website.service

服务启动但 localhost:5000或 https://localhost:5001不打开
和

sudo systemctl status website.service

给出:

website.service - Example .NET Web API App running on Ubuntu
     Loaded: loaded (/etc/systemd/system/website.service; enabled; vendor prese>
     Active: activating (auto-restart) (Result: exit-code) since Sat 2021-08-21>
    Process: 2421 ExecStart=/usr/bin/dotnet /root/dev/myWebApp/myWebApp/myWebAp>
   Main PID: 2421 (code=exited, status=200/CHDIR)

笔记:
重新创建 ASP.NET 核心环境和项目的步骤:
安装 dotnet core 5.0

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt update
sudo apt install apt-transport-https
sudo apt update
sudo apt install dotnet-sdk-5.0

创建、构建和发布 asp.net 核心项目

mkdir dev
cd dev
dotnet --info
dotnet new webApp -o myWebApp   //Create a basic web application that should listen on 5000 port
cd myWebApp
dotnet build    //Builds the project
dotnet publish -c release -o myWebApp   //Publishes the project as a myWebApp.dll on /root/dev/myWebApp/myWebApp/myWebApp.dll path, it should run in "website.service" file

Answer 1

我找到了答案，服务文件不从/root/dev 文件夹运行 dll，它从/var/www 文件夹运行文件正常。
