Nginx知多少系列之(五)Linux下托管.NET Core项目

在这里我就不介绍如何在Linux上部署.Net Core以及进程守护监控等内容，如果需要可以查看之前发布的文章。《.NET Core项目部署到Linux(Centos7)（六）发布.NET Core 项目到Linux》、《.NET Core项目部署到Linux(Centos7)（七）启动和停止.NET Core项目》、《.NET Core项目部署到Linux(Centos7)（八）为.NET Core项目创建Supervisor进程守护监控》

ASP.NET Core内置了Kestrel服务器，但功能简单，不是一个全功能的Web服务器，主要用于SelfHost，它旨在使ASP.NET尽可能快，但其管理安全性和提供静态文件的能力有限，正式运行还是要依赖IIS、Apache、Nginx等功能全面的服务器，为ASP.NET Core程序提供类似缓存、压缩请求、SSL终端等高深的特性或功能。这两种服务器的关系是：Nginx、IIS等作为Kestrel的反向代理服务器。

1.端口映射配置

#编辑nginx.conf
sudo vim  /etc/nginx/nginx.conf

#进入文件后，按“i”或者“a”进入插入模式，插入下面的配置信息

进去注释掉http配置下server的默认配置内容

# For more information on configuration, see:

#   * Official Russian Documentation: http://nginx.org/ru/docs/

user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;

# Load dynamic modules. See /usr/share/doc/nginx/README.dynamic.
include /usr/share/nginx/modules/*.conf;

events {
    worker_connections 1024;
}

http {
    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;
    tcp_nodelay         on;
    keepalive_timeout   65;
    types_hash_max_size 2048;

    include             /etc/nginx/mime.types;
    default_type        application/octet-stream;

    # Load modular configuration files from the /etc/nginx/conf.d directory.
    # See http://nginx.org/en/docs/ngx_core_module.html#include
    # for more information.
    include /etc/nginx/conf.d/*.conf;

#    server {
#        listen       80 default_server;
#        listen       [::]:80 default_server;
#        server_name  _;
#        root         /usr/share/nginx/html;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        location / {
#        }
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#    }

# Settings for a TLS enabled server.
#
#    server {
#        listen       443 ssl http2 default_server;
#        listen       [::]:443 ssl http2 default_server;
#        server_name  _;
#        root         /usr/share/nginx/html;
#
#        ssl_certificate "/etc/pki/nginx/server.crt";
#        ssl_certificate_key "/etc/pki/nginx/private/server.key";
#        ssl_session_cache shared:SSL:1m;
#        ssl_session_timeout  10m;
#        ssl_ciphers HIGH:!aNULL:!MD5;
#        ssl_prefer_server_ciphers on;
#
#        # Load configuration files for the default server block.
#        include /etc/nginx/default.d/*.conf;
#
#        location / {
#        }
#
#        error_page 404 /404.html;
#            location = /40x.html {
#        }
#
#        error_page 500 502 503 504 /50x.html;
#            location = /50x.html {
#        }
#    }

}

#按ESC，输入命令保存配置文件
:wq   (保存编辑操作退出)
:wq!  (保存编辑强制退出)
:w ! sudo tee %

注释完原来的映射之后，我们需要在/etc/nginx/conf.d文件夹下为.Net Core项目新建一个DemoNetCore.conf文件，文件配置如下

#进入conf.d文件夹
cd /etc/nginx/conf.d

#创建配置文件
sudo touch DemoNetCore.conf

#编辑配置文件
sudo vim DemoNetCore.conf

#配置文件信息
server {
    listen       80;
    location / {
    proxy_pass http://localhost:8081;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection keep-alive;
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
    }
}

配置好之后重启Nginx，重启的时候可能会直接报错，如下图

#重启Nginx
sudo systemctl restart nginx
