Preface: .Net Core Program (website) can be deployed in windows IIS, can be deployed on Linux (more recommended)
This article deployment, based on .net core 2.1, server CentOS 7, you need to install the service has two: Nginx, SuperVisor ( process guardian )
Preview command:
Linux: restart: reboot Nginx: Strong kill: killall - 9 nginx test configuration is correct: nginx - t start: nginx SuperVisor: Stop: supervisorctl shutdown start: supervisord
The following description :( I to develop an online notepad BookkeepingWeb for example)
One. Do the project locally
Develop good Web, and configure the port-programmed listening (not configured, the default port 5000, if the server deploying multiple web, then this should change the port), VS inside, or cmd into the project to publish, \ bin under the publishing project \ Debug \ netcoreapp2.1 \ after publish,
In cmd into the project running: dotnet program name .dll, browser hit cmd prompt access address, to ensure the normal access.
Find the program path: D: \ study \ consoleTest \ Bruke.Bookkeeping \ Bruke.Bookkeeping.Core.Web \ bin \ Debug \ netcoreapp2.1 \ publish
Entrance start the program: Bruke.Bookkeeping.Core.Web.dll
运行起来：打开cmd 进入程序路径 执行： dotnet 程序入口名称
执行：dotnet Bruke.Bookkeeping.Core.Web.dll
浏览器查看是否可以访问：http://localhost:5000 ，如图正常。
当cmd关闭或 程序shut down(Ctrl+C) 时， 网站就是访问不了，说明，由cmd单线程监听端口，并执行和返回的。比如浏览器访问了本地5000端口，就会给这个单线程的cmd捕获到，并执行你的代码后返回到浏览器。
至此，本地程序是没问题的，那么就可以把publish拷贝到Linux服务器上了，下面是服务器如何设置监听端口，并转发请求的。
附（设置端口）的博文，可以先忽略该文：https://www.cnblogs.com/1175429393wljblog/p/8267772.html
二.服务器操作
1.接下来就是把publish 拷贝到Linux服务器上去即可，推荐使用 SecureCRSecureFXPortable，可以上传文件，命令运行。

在服务器 /root 添加文件夹 BookkeepingWeb,把publish的东西拷贝上来。
2.服务上安装.Net Core SDK (基于你的项目版本去安装，我的服务器，安装了.net core 3.0.1,和.net core 2.1,以下为core 2.1为例)
微软官网：https://dotnet.microsoft.com/download/linux-package-manager/rhel/sdk-current
（这个是官网的推荐的sdk 默认3.0版本）
寻找对应2.1的版本：https://dotnet.microsoft.com/download/dotnet-core
https://dotnet.microsoft.com/download/dotnet-core/2.1
执行：sudo rpm -Uvh https://packages.microsoft.com/config/centos/7/packages-microsoft-prod.rpm
执行：sudo yum install dotnet-sdk-2.1
安装.net core运行环境完毕。
3.服务上安装Nginx:
（可以参考：https://www.jianshu.com/p/e1b5ee442a70）
命令：
curl -o nginx.rpm http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm
rpm -ivh nginx.rpm
yum install nginx
至此，安装完毕，外网访问服务器,访问80端口，如图说明，Ngnix部署成功，并完成了监听端口（80）。
打开服务器的目录 /etc/nginx
把配置文件拷贝下来到本地编辑后上传，或者直接在服务器上编辑（不推荐），在本地编辑时，注意使用编码是：utf-8 无bom的格式。
a. nginx.conf
如果nginx.conf和图上没什么区别，就不用管，如果是不同，参考或复制下面的
worker_processes 1; 这个表示nginx运行处理的线程数，推荐使用cpu核数的2倍（https://www.cnblogs.com/aaron-agu/p/8003831.html）
#user nginx; worker_processes 1; #error_log /var/log/nginx/error.log warn; #pid /var/run/nginx.pid; events { worker_connections 1024; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; }
b. default.conf
多个Web,可以使用多个server{}来设置转发
listen 80;Nginx对外表示监听了80端口，有人访问，IP:80就会使用该配置。
server_name jz.test.com www.test.com;绑定域名(多个域名绑定到同一个web时 ，使用空格隔开即可)
proxy_pass 这个是设置该请求转发的到服务器本地的端口（比如我们的这个项目是5000端口，那么转发过去给它处理就好）
server { listen 80; location / { proxy_pass http://localhost:5000; } }
至此，配置完成，把本地的这2个配置，替换到服务器上对于的位置即可。
接下来让Nginx重新加载配置即可（nginx不会自动加载配置的）
使用命令：nginx -t 查看nginx 配置是否配置的对。不正常的话，检查一下配置。
推荐使用：killall -9 nginx 杀死所以nginx 进程。
然后启动命令：nginx
至此，nginx在外网的访问下（80端口），会进行转发到端口5000。
Nginx配置完毕。
4.服务上运行咱们的应用程序:
方法和我们本地上很像啦。
无非就是CD到我们发布的那个目录，执行 dotnet 程序名称.dll
无报错就是启动完成了。这时候，可以用外网浏览器服务IP:80。即可访问到我们的网站了
（原理是，启动网站后，该网站会一直监听我们的端口5000，外网访问的80端口会给Nginx转发到5000，那么我们的网站就可以捕获到并处理返回）。
至此，web部署完毕。
不好意思，还有后续，什么？你忘了我们本地的CMD窗口了吗？只要关闭，或者shut down 就GG。
所以你web虽然部署好了，但是你这个是单线程窗口，只能在里面，退不出来，断开服务器命名窗口，也一样，对不起，GG。
哦，是的，web启动了，和我们的本地的那个cmd太像了，那么我们就需要把我们的网站搞成另一个进程程来执行它，并不退出（俗称进程守护）。
5.安装supervisor进程守护:
【安装Supervisor】
yum install python-setuptools
easy_install supervisor
【配置Supervisor】
mkdir /etc/supervisor
新增一个文件：（这一句不是命令） /etc/supervisor/supervisord.conf
【修改supervisord.conf文件，将文件尾部的配置】
;[include]
;files = relative/directory/*.ini
改成
[include]
files = conf.d/*.conf
注意：conf.d是没有自动创建的，自己手动创建一个，还有就是参考下面的图片，如果没有的，都要自己创建文件夹或文件，配置也贴下面了
supervisord.conf 的代码：
; Sample supervisor config file. ; ; For more information on the config file, please see: ; http://supervisord.org/configuration.html ; ; Notes: ; - Shell expansion ("~" or "$HOME") is not supported.

这些便是要执行的配置。
如图，该好对应的配置，比如守护名称，命令，命令执行的目录，执行人权限啊。
相当于这配置，就是把我们的手动启动web的工作，交个这个文件，由守护进程去执行即可
DotNetCoreWeb.conf的代码：
[program:DotNetCoreWeb] command=dotnet Bruke.VideoOnline.Web.dll ; directory=/root/Bruke.VideoOnline.Web/ ; autorestart=true ; stderr_logfile=/var/log/DotNetCoreWeb.err.log ; stdout_logfile=/var/log/DotNetCoreWeb.out.log ; environment=ASPNETCORE_ENVIRONMENT=Production ; user=root ; stopsignal=INT
参考图中的备注：
最后启动 运行，查看是否生效
命令：supervisord
下面是执行配置，并守护到后台去。
supervisord -c /etc/supervisor/supervisord.conf
ps -ef | grep DotNetCoreWeb
至此。如果没报错，使用外网即可访问。
