最近在研究学习nginx，买了腾讯云服务器、在阿里上申请了域名，部署项目遇到很多问题记录一下，以备后用：
1.在腾讯服务器买好（如果登录密码不知道可以重置），阿里域名申请好后（也可以在腾讯上申请域名），需要添加安全组，创建不同的规则，在入站规则中添加各个需要的TCP端口，具体创建方式自行百度。
2.登录到阿里域名后申请域名解析，添加网址解析记录，设置@、www等，添加对应项目的端口。
3.在服务器上部署好项目，安装nginx，将loopback项目部署。安装命令：
sudo apt-get install nginx
4.nginx基本操作命令
5.如果登录默认用户时，创建文件的权限不够，可以执行命令将文件变成当前用户私有文件:
sudo chown -R 组名（随便写）:用户名 文件夹/
重启：sudo service nginx restart
修改配置文件：vi /etc/nginx/nginx.conf，这个是关键问题，搞了好久，附上我的配置文件：
user www-data;
worker_processes auto;
pid /run/nginx.pid;

worker_connections 768;

切记 proxy_pass http://xxxxx.com:3001/，最后的"/"必须加上。
