C# 使用.NET core 3/3.1的Linux CentOS 8中未显示任何日志

我很想给出错误信息，但这是我得到的全部

我错过什么了吗？在.NETCore3.1和2.1/2.2版本中，Linux部署做了额外的改变吗

我试着尽快注销

将

.WriteTo.Console（）

添加到serilog设置中如何？您还需要在相关的csproj文件中包含此包：

您似乎正在将日志写入

/var/log/gweb/gweb.log

，但正在读取

/var/log/messages

？我已经尝试过了，但检查时没有日志输出到

/var/log/gweb/gweb.log

。所以我希望就是这样。谢谢你！最后，我可以像一个正常人一样调试，而无需拔出我的头发<代码>[13:44:22错误]出了问题。UTC:3/1/2020 12:44:22 PM[13:44:22 ERR]错误：2006D080:BIO例程：BIO_new_文件：Interop.Crypto.checkvalidOpensLX509CertificateReader.FromFile中的Interop.Crypto.checkvalidOpensLX509KeystrageFlags中没有这样的文件[13:44:22 ERR]。
