反向代理采用Nginx，当客户端向Nginx服务器发送请求时，Nginx转发给集群，当请求到达Nginx时可以加一层缓存，可存储动态页面，当缓存存在时Nginx直接将缓存返回给客户端，而不请求服务器，这样可以将一大部分请求拦截到直接返回缓存，使服务器压力降低。

应用程序
创建一个.net core 3.0 MVC程序
public class HomeController : Controller { private readonly IConfiguration _iConfiguration; public HomeController( IConfiguration configuration) { this._iConfiguration = configuration; } public IActionResult Index() { ViewBag.Time = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss fff"); ViewBag.InternalUrl = $"{base.Request.Scheme}://:{this._iConfiguration["port"]}"; return View(); } }
public class testController : Controller { private readonly IConfiguration _iConfiguration; public testController(IConfiguration configuration) { this._iConfiguration = configuration; } public IActionResult Index() { ViewBag.Time = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss fff"); ViewBag.Url = $"{base.Request.Scheme}://{base.Request.Host}"; ViewBag.InternalUrl = $"{base.Request.Scheme}://:{this._iConfiguration["port"]}"; return View(); } }
将时间与端口作为标记，在页面上打印出来，接下来添加命令行支持，打开Program.Main()，添加命令行支持
public static void Main(string[] args) { new ConfigurationBuilder() .SetBasePath(Directory.GetCurrentDirectory()) .AddCommandLine(args) .Build(); CreateHostBuilder(args).Build().Run(); } //core 2.x 使用 //public static IWebHost BuildWebHost(string[] args) => // WebHost.CreateDefaultBuilder(args) // .UseConfiguration(new ConfigurationBuilder().AddCommandLine(args).Build()) // .UseStartup<Startup>() // .Build();
接下来就可以用命令行启动项目了，进入bin/Debug/netcoreappx.x下cmd输入：
dotnet xxx.dll --urls=http://*:8878 --port=8878
成功后就能打开浏览器地址访问了~
到这项目已经能顺利启动了，接下来配置Nginx反向代理服务器。
打开conf/nginx.config配置文件进行配置 先在http节点下include前配置（data文件夹要先创建，默认当前地址./为与nginx.exe同级目录，../data为nginx-1.18.0同级）
proxy_cache_path ../data/ levels=1:2 keys_zone=cache_one:500m inactive=1d max_size=1g;
然后配置下服务转发列表
upstream web
{
server 127.0.0.1:8878;
server 127.0.0.1:8879;
server 127.0.0.1:8877;
}
最后在server节点下配置，这样就能转发给多个地址
location /
{
#代理地址，自动转发到web列表
proxy_pass http://web;
}
在/test路由上使用缓存
location /test
{
#使用上面的缓存地址
proxy_cache cache_one;
#缓存200 304 302请求1个小时
proxy_cache_valid 200 304 302 1;
proxy_pass http://web;
proxy_cache_key $uri$is_args$args;
}
现在先访问localhost:8080/home看看集群是否配置成功
可以看到访问8080端口后转发到了8878应用程序，多刷几次看看
这样就配置好了，接下来就能测试nginx反向代理缓存,上面的nginx配置文件配置了/text路由的缓存
访问到/test路由后，多次刷新页面一直都没有改变，没错，动态页面被缓存了。当请求发送到8080端口nginx服务器后由nginx缓存了，第二次请求直接返回，并没有转发出去。去看看nginx缓存目录下存在的缓存文件。
如果把缓存删除掉就能重新访问到服务器。
附上nginx.config
