Linux 在步骤CHDIR繁殖失败/usr/bin/dotnet“文件：没有这样的文件或目录

我尝试将ASP.NETCore2网站部署到Ubuntu

但是，它会引发一个异常：

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

但是，命令/usr/bin/dotnet存在，当我运行时，它还可以

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

我在谷歌上搜索了一下，但我找到的最佳答案表明它与用户的www数据有关。但我还是不知道出了什么问题。任何帮助都将不胜感激。

查看工作目录路径，cd直接指向路径。 在我的例子中，WorkingDirectory路径文件夹丢失，当我手动创建它时，它开始工作

希望这有帮助

安装dotnet核心

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

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

创建文件后运行这些命令

systemd-escape "<value-to-escape>"
sudo systemctl enable api.service
sudo systemctl start api.service
sudo systemctl status api.service

systemd转义“”
sudo systemctl enable api.service
sudo systemctl启动api.service
sudo systemctl status api.service

始终验证文件和文件夹的位置

您是否确保用户

www data

具有

/var/aspnetcore/hellomvc

的读取权限？@Evk。非常感谢。看来这就是问题所在。www数据被授予权限后，它工作了！
