在Docker下载Nginx镜像

docker pull nginx docker images

Docker nginx安装与配置挂载并实现负载均衡

  • 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

    For more information on configuration, see:

  • 启动容器

    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

这里写图片描述

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
