Question

我尝试在https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/linux-nginx?view=aspnetcore-2.1&tabs=aspnetcore2x之后将ASP.NET Core 2网站部署到Ubuntu。

然而，它引发了一个例外：

Failed at step CHDIR spawning "/usr/bin/dotnet": No such file or directory from the file

错误来自此文件

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

[Service]
WorkingDirectory=/var/aspnetcore/hellomvc
ExecStart=/usr/bin/dotnet /var/aspnetcore/hellomvc/hellomvc.dll
Restart=always
RestartSec=10  # Restart service after 10 seconds if dotnet service crashes
SyslogIdentifier=dotnet-example
User=www-data
Environment=ASPNETCORE_ENVIRONMENT=Production
Environment=DOTNET_PRINT_TELEMETRY_MESSAGE=false

[Install]
WantedBy=multi-user.target

然而，命令/ usr / bin / dotnet存在，当我运行

时它很好

/usr/bin/dotnet /var/aspnetcore/hellomvc/hellomvc.dll

我用Google搜索了，但我发现的最佳答案表明它与用户www-data有关。我仍然无法弄清楚出了什么问题。任何帮助将不胜感激。

Answer 1

查找WorkingDirectory路径，将cd直接查找到该路径。就我而言，WorkingDirectory路径文件夹丢失了，当我手动创建它时，它开始工作。

希望此帮助。

Answer 2

安装dotnet核心

count

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

在创建文件后运行这些命令

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.asc.gpg
sudo mv microsoft.asc.gpg /etc/apt/trusted.gpg.d/
wget -q https://packages.microsoft.com/config/ubuntu/18.04/prod.list
sudo mv prod.list /etc/apt/sources.list.d/microsoft-prod.list
sudo chown root:root /etc/apt/trusted.gpg.d/microsoft.asc.gpg
sudo chown root:root /etc/apt/sources.list.d/microsoft-prod.list
sudo apt-get update
sudo apt-get install apt-transport-https
sudo apt-get install dotnet-sdk-2.1

NB 始终验证文件和文件夹的位置

步骤CHDIR产生“/ usr / bin / dotnet”失败：没有这样的文件或目录
