asp.net-core - Serilog 未在 Ubuntu 上写入文件

Question

我已将网站部署到 ubuntu 机器但无法让 serilog 写入文件
这是我所拥有的:
在 Program.cs 中(省略不必要的部分):

 public static void Main(string[] args)
    {
        var environment = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT");
        var configuration = new ConfigurationBuilder()
             .AddJsonFile("appsettings.json", optional: false, reloadOnChange: true)
             .AddJsonFile($"appsettings.{environment}.json", optional: true)
             .AddEnvironmentVariables()
             .Build();

        Log.Logger = new LoggerConfiguration()
            .ReadFrom.Configuration(configuration)
            .CreateLogger();

还:

return Host.CreateDefaultBuilder(args)
            
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder

                .UseUrls($"http://localhost:{port}")
                .UseStartup<Startup>();
            })
            .UseSerilog();

在我的 appsetting.PreProduction.json 中:

"Serilog": {
"MinimumLevel": "Information",
"WriteTo": [
  {
    "Name": "File",
    "Args": {
      "path": "/var/log/myapp/",
      "rollingInterval": "Day"
    }
  }
]

},
这适用于我的本地计算机 Windows

 {
    "Name": "File",
    "Args": {
      "path": "c:\\myapp\\log.txt",
      "rollingInterval": "Day"
    }
  },

我需要明智地做任何额外的许可吗？

我不得不重新启动服务:

sudo systemctl restart myapp.service

还必须设置权限:

mkdir /var/log/myapp/
chown apiuser:apiuser /var/log/myapp/
chmod 740 /var/log/myapp

我一直在重新启动 nginx，但不知道我也必须重新启动服务
