dpkg安装Nginx
Debian使用apt-get作为软件包管理器，所以我们可以使用apt-get直接安装dpkg，进而安装Nginx：
apt-get install nginx安装完以后，输入whereis nginx查看Nginx的安装位置，其中的nginx.conf为Nginx的配置文件。
常用Nginx命令
这边给大家介绍一些Nginx常用命令：

安全地停止Nginx服务（即处理完所有请求后再停止服务） |
1. 我想让一个demo 站点直接域名访问，不带端口，所以想用 80 端口启动对应前端工程。
发现 80 被 nginx 占用：
2. 修改 nginx 端口，只需要修改其监听的端口就行了。
找到 nginx 的配置文件，并编辑 listen 后面的端口号就行了。
如 我把原本的 80 改为了8082：
文件目录：
root@li:/etc/nginx/sites-available#
dir
default(*用vi default修改这个文件)
3. 重新加载 nginx 配置、重启 nginx 都行。
# 启动
./nginx
./nginx -s stop
./nginx -s quit
./nginx -s reload再次查看，nginx 的端口已经变更为 8082 了。
4. 重新启动原前端工程成功。
cd /var/www/html;
