nginx

 制作镜像：

FROM alpine
MAINTAINER don
RUN apk --update add nginx
COPY nginx.conf /etc/nginx/nginx.conf
EXPOSE 80
CMD ["nginx","-g","daemon off;"]

 容器80端口映射成host的50448，host ip是 52.82.52.63，浏览器里输入的内容：http://52.82.52.63:50448/

    upstream zp_server1{
        server 52.82.52.63:50449;
    }
    server {
        listen       80;
        server_name  52.82.52.63;
                location / {
                    proxy_pass http://zp_server1;
                }

    }

=================负载均衡示例,共发起了1000个请求，两个应用各收到500个

events {
        # The maximum number of simultaneous connections that can be opened by
        # a worker process.
        multi_accept on;
        use epoll;
        worker_connections 1024;
}
upstream zp_server1{
        server 52.82.52.63:50449;
        server 52.82.52.63:50447;
    }
    server {
        listen       80;
        server_name  52.82.52.63;
                location / {
                    proxy_pass http://zp_server1;
                }

    }

============下面第一条是检查配置文件是否有语法问题；第二句是重新加载配置文件

====================nginx模块讲解

============配置语法

通过ab工具进行压力测试

 

 ==========访问控制=====

通过http://www.ip138.com/查询出口ip，公网通过138查询，内网实验环境通过ipconfig就能查询到

局限性的解决办法：

需要输入密码才能访问
