Linux+asp.net Core+nginx Four-layer load balancing

Linux Disibutaion:ubuntu 16.04.1 LTS

Web Server:nginx, Kestrel

about how to deploy ASP. NET core in Linux I'm not in the details here, so you can refer to ASP. Run on Linux (Ubuntu)
Here I need three VMS:
NGINXVM01: Doing a Load balancer server
NGINXVM02: Service Node 1
NGINXVM03: Service Node 2
Approximate service architectures such as:

Configure the Load Balancer node (NGINXVM01):

sudo apt-get install-y nginxsudo touch/etc/nginx/sites-available/nginxlb-proxysudo vi/etc/nginx/sites-available/ Nginxlb-proxy

Nginx site configuration files are in the/etc/nginx/sites-available directory.

The active Web site is in the/etc/nginx/sites-enabled directory.

Nginx configuration Files Reference configuration file Structure in the Nginx guide

Write the contents to the Nginxlb-proxy file:

Upstream nginxlb{        server nginxservice.cloudapp.net:8082;        Server nginxservice.cloudapp.net:8083;} server {          listen 8081 default_server;        server_name nginxservice.cloudapp.net;        Location/        {                proxy_pass http://nginxlb;                Proxy_set_header x-real-ip $remote _addr;                Proxy_next_upstream Error timeout Invalid_header http_500 http_502 http_503;        }

There are multiple modes for load balancing using Nginx, refer to official website using Nginx as HTTP load balancer

I have tested the various load modes of nginx.

Reboot loading Nginx configuration file

sudo nginx-tsudo nginx-s Reload

To this step, nginx default enabled sites are the defaults, we need to change the enabled site to Nginxlb-proxy

sudo ln-s/etc/nginx/sites-available/nginxlb-proxy/etc/nginx/sites-enabled/  #删除默认启用的站点defaultsudo rm/etc/ Nginx/sites-enabled/default
