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

  • 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:

    Load dynamic modules. See /usr/share/nginx/README.dynamic.

  • 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

  • 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
