Docker 中使用Nginx网站的搭建

Docker 中使用Nginx网站的搭建

使用Nginx 来搭建完整的前置站点，实现后向的代理，这篇文章中简单介绍一个搭建的步骤，至于Nginx 的知识，Docker 的使用可以参考对应的文档。

前提条件

• Ubuntu (20.04)
• Docker (23.0.1 Community)
• Nginx

安装步骤

• Ubuntu
  • 云服务器，国内的国外的都行，花点钱买一台
• Docker 安装步骤，参考链接,做个简单的翻译
  • 首先更新系统 sudo apt update
  • 安装一些依赖的软件 sudo apt install apt-transport-https ca-certificates curl software-properties-common
  • 将Docker 官网仓储添加到系统的GPGkey中 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
  • 将Docker 仓储添加到APT源中echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
  • 更新系统 sudo apt update
  • 再次确认一下，你是从docker仓储中安装而不是ubuntu 中安装apt-cache policy docker-ce
  • 安装Dockersudo apt install docker-ce
  • 检查一下Docker的守护进程是否运行sudo systemctl status docker
• 介绍几个Docker 中常用的命令

• Nginx 安装步骤 参考链接

  • 拉取docker 源 docker pull nginx
  • 启动nginx docker run --name docker-nginx -p 80:80 nginx
    • 这样我们就启动了一个默认配置下的nginx 服务器，监听端口在80.

• 下面我们要启动两个不同的网站，他们在同一台服务器下，同一个端口，只是通过不同的域名访问。假设域名为DomainA.com, DomainB.com端口都是80.

  • 首先基于上一步，我们先从docker 中copy 出一个默认的配置文件
    docker cp docker-nginx:/etc/nginx/conf.d/default.conf ~/default.conf
  • 然后修改这个文件,先复制里面的server directive, 然后将里面的server 配置成DomainA.com, 第二个server 配置成DomainB.com
  • 修改里面的root, 加入改成/var/www/SiteA, /var/www/SiteB
  • 在我们的ubuntu 上也新建一个SiteA,SiteB 的目录放入html.
  • 我们通过磁盘挂载的方式来启动nginx,具体参考这个链接
  • 首先我们把上一步的nginx 删除 docker rm docker-nginx
  • 重新启动 docker run --name docker-nginx -p 80:80 -v /local/SiteA:/var/www/SiteA -v /local/default.conf:/etc/nginx/conf.d/default.conf -v /local/SiteB:/var/www/SiteB

  Happy Coding
