以下の説明:(私は例えば、オンラインメモ帳BookkeepingWebを開発します)

A. ローカルプロジェクトを実行します。

良いWebの開発、およびポートプログラムリスニング設定(設定されていない、デフォルトのポート5000を、サーバーが複数のWebを展開している場合、このポートを変更する必要があります)、VSの内側、または公開するプロジェクトにcmdを、出版プロジェクトの下の\ binに\デバッグ\ netcoreapp2.1後に公開\、

プロジェクトの実行中にCMDで:DOTNETプログラム名の.dll、ブラウザは通常のアクセスを確保するために、CMDプロンプトアクセスアドレスをヒット。

 

プログラムパスを探す:D:\研究\ consoleTest \ Bruke.Bookkeeping \ Bruke.Bookkeeping.Core.Web binに\デバッグ\ \ netcoreapp2.1 \公開

エントランスには、プログラムを起動します。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。

链接: https://pan.baidu.com/s/15kDCQn3xSg4PyZO5R4gPLw 提取码: punw 

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;
}
View Code

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;
    }
}
View Code

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.  Environment
;    variables can be expanded using this syntax: "%(ENV_HOME)s".
;  - Quotes around values are not supported, except in the case of
;    the environment= options as shown below.
;  - Comments must have a leading space: "a=b ;comment" not "a=b;comment".
;  - Command will be truncated if it looks like a config file comment, e.g.
;    "command=bash -c 'foo ; bar'" will truncate to "command=bash -c 'foo ".
;
; Warning:
;  Paths throughout this example file use /tmp because it is available on most
;  systems.  You will likely need to change these to locations more appropriate
;  for your system.  Some systems periodically delete older files in /tmp.
;  Notably, if the socket file defined in the [unix_http_server] section below
;  is deleted, supervisorctl will be unable to connect to supervisord.

; include files themselves.

[include]
files = conf.d/*.conf
supervisord.conf

 

 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
View Code

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。
