Docker nginx安装与配置挂载的方法

在Docker下载Nginx镜像

docker pull nginx
docker images

创建挂载目录

mkdir -p /data/nginx/{conf,conf.d,html,logs}

编写nginx,conf配置文件，并放在文件夹中

user nginx;

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

  worker_connections 1024;
}

    }

      location = /40x.html {
    }

    error_page 500 502 503 504 /50x.html;
      location = /50x.html {
    }
  }

  upstream pic{
        server 182.254.161.54:8088 weight=5;

  }

}

启动容器

代码如下：

docker run --name mynginx -d -p 82:80  -v /data/nginx/conf/nginx.conf:/etc/nginx/nginx.conf  -v /data/nginx/logs:/var/log/nginx -d docker.io/nginx

查看启动的容器

docker ps

先前已经在Docker部署两个tomcat，一个是8088端口，另一个是8089端口，并进入两个容器里编写了简单的页面

访问8088端口

访问8089端口

现在通过Nginx访问两个tomcat的内容，实现负载均衡的功能，出于区别，更能体现负载均衡的功能，两个页面的内容不一样，但是访问路径都一样，只是通过Nginx反向代理去轮换访问
