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

}启动容器
复制代码 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
