如何在Nginx代理后面的Unix域套接字中托管ASP.NET Core 2.0(Kestrel)? [英] How to host ASP.NET Core 2.0 (Kestrel) with Unix domain socket behind a nginx proxy?
问题描述
我当前在Ubuntu 16中通过HTTP请求在nginx后面使用ASP.NET Core 2.0.
I am current using ASP.NET Core 2.0 behind nginx through HTTP requests in Ubuntu 16.
我想切换到Unix域套接字.
And I'd like to switch to Unix domain socket.
在我的 Program.cs 中,我有:
var host = default(IWebHost);
var builder = new WebHostBuilder()
.UseKestrel(opt =>
{
if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux) && settings.Config.ListenUnixSocket)
{
opt.ListenUnixSocket("/tmp/api.sock");
}
})
.Configure(app =>
{
app.Map("/health", b => b.Run(async context =>
{
context.Response.StatusCode = (int)HttpStatusCode.OK;
await context.Response.WriteAsync("Ok");
}));
});
if(RuntimeInformation.IsOSPlatform(OSPlatform.Windows) || !settings.Config.ListenUnixSocket)
{
host = builder.UseUrls("http://0.0.0.0:5501").Build();
}
else
{
host = builder.Build();
}
host.Run();
然后,在 Nginx :
location /health {
#proxy_pass http://127.0.0.1:5501;
proxy_pass http://unix:/tmp/api.sock:/;
}
使用默认的TCP套接字运行它可以工作,但是切换到Unix域套接字时,出现了502错误.
Running it using the default TCP socket works, but switching to Unix domain sockets, I got a 502 error.
在Nginx上需要任何特定的模块吗?我在做什么错了?
Do I need any specific module at nginx? What I am doing wrong?
推荐答案
Aspnetcore在运行时将创建api.socket,但Nginx必须具有写权限.
Aspnetcore will create api.socket when its running but Nginx must have permission to write.
因此,如果您不知道nginx用户使用什么,请执行:
So, if you don't know what user nginx uses, execute:
ps aux | grep nginx
您将在终端中得到一些东西
You'll get something this in the terminal:
root 5005 0.0 0.2 125116 1460 ? Ss 20:12 0:00 nginx: master process /usr/sbin/nginx -g daemon on; master_process on;
www-data 5006 0.0 0.6 125440 3260 ? S 20:12 0:00 nginx: worker process
root 5173 0.0 0.1 14516 920 pts/0 S+ 20:17 0:00 grep --color=auto nginx
然后您设置权限:
sudo chown www-data:www-data /tmp/api.sock
就这样!
