如何为dotnet应用程序创建服务

Question

我需要帮助为linux上的aspnetcore应用程序创建服务。我开发并创建了一个应用程序，它在我用./Application启动它时运行。但是如果我创建一个服务，它就失败了。

状态导致：

● alphabot.service - AlphaBot Service
     Loaded: loaded (/etc/systemd/system/alphabot.service; enabled; vendor preset: enabled)
     Active: failed (Result: core-dump) since Tue 2021-06-29 18:03:32 UTC; 1s ago

alphabot.service:

[Unit]
Description=AlphaBot Service

[Service]
Type=simple
ExecStart=/home/alphabot/AlphaBot

[Install]
WantedBy=multi-user.target

Answer 1

服务运行良好，但应用程序本身正抛出一个错误。

运行journalctl -u alphabot -f，重新启动服务并监视终端。可能是一个繁忙的端口，配置文件.

Answer 2

[Unit]
Description=AlphaBot Service

[Service]
Type=simple
ExecStart=/usr/bin/dotnet /home/alphabot/AlphaBot.dll

[Install]
WantedBy=multi-user.target

结果：

● alphabot.service - AlphaBot Service
     Loaded: loaded (/etc/systemd/system/alphabot.service; enabled; vendor preset: enabled)
     Active: failed (Result: core-dump) since Tue 2021-06-29 18:15:28 UTC; 872ms ago
