創建一個 container
$ docker run -p 80 --name ubuntu_web -i -t ubuntu /bin/bash
root@8c9885237635:/#
端口映射使用docker run -P -p；
-P 將容器暴露的所有端口進行映射
-p 只暴露指定的端口
Nginx 部署流程
1. 創建80 端口的交互式容器
2. 安裝 Nginx
3. 安裝文本編輯器vim
4. 創建靜態頁面
5. 修改 Nginx配置文件
6. 運行Nginx
7. 驗證網站訪問
- 創建80 端口的交互式容器
$ docker run -p 80 --name ubuntu_web -i -t ubuntu /bin/bash
root@8c9885237635:/#
- 安裝 Nginx
先更新源，在安裝 nginx
root@8c9885237635:/# apt-get update
root@8c9885237635:/# apt-get install -y nginx
- 安裝文本編輯器vim
# apt-get install -y vim
- 創建靜態頁面
root@8c9885237635:/# cd /var/www/html/
root@8c9885237635:/var/www/html# vim index.html
- 修改 Nginx配置文件
修改 root 爲 /var/www/html
root@8c9885237635:/var/www/html# vi /etc/nginx/sites-enabled/default
- 運行Nginx
root@8c9885237635:~# nginx
root@8c9885237635:~# { CTRL P, CTRL Q} 退出後臺運行
- 驗證網站訪問
觀察映射已經成功， 而且docker 在後臺運行
docker ps
