Docker中nginx如何安装与配置挂载

小编给大家分享一下Docker中nginx如何安装与配置挂载，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

在Docker下载Nginx镜像

docker pull nginxdocker 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
