Question

我收到以下错误：

Jun 03 06:41:04 {my_digital_ocean_server} systemd[13752]: kestrel-hellomvc.service: Failed at step CHDIR spawning /usr/bin/dotnet: No such file or directory
-- Subject: Process /usr/bin/dotnet could not be executed
-- Defined-By: systemd
-- Support: http://lists.freedesktop.org/mailman/listinfo/systemd-devel
--
-- The process /usr/bin/dotnet could not be executed and failed.

运行时：

systemctl start kestrel-hellomvc.service

遵循本指南： https://docs.microsoft.com/en-us/aspnet/core/publishing/linuxproduction

正在运行：nano /usr/bin/dotnet为我提供一个包含内容的大文件，并返回which dotnet / usr / bin / dotnet，所以文件确实存在（？）。

为什么我会收到此错误，解决方案是什么？

编辑：我的/etc/systemd/system/kestrel-hellomvc.service文件：

[Unit]
Description=Example .NET Web API Application 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=root
Environment=ASPNETCORE_ENVIRONMENT=Production 

[Install]
WantedBy=multi-user.target

Answer 1

Dotnet可能不在usr / bin中。在Ubuntu Server 16.04上，我的位于/ usr / share / dotnet，服务文件中的可执行行是/ usr / share / dotnet / dotnet。

Answer 2

做

which dotnet

找到您的应用服务文件/etc/systemd/system/kestrel-MyAppName.service属性的正确路径

ExecStart=/bin/dotnet /var/www/dev-slc1.almw.local/public_html/MyAppName.dll

例如，在CentOS7上，which dotnet的结果为：/bin/dotnet。
