数据目录：/var/www
站点配置目录：/var/www/conf
站点数据目录：/var/www/wwwroot
站点证书目录：/var/www/wwwssl
站点日志目录：/var/www/wwwlog

创建新站点：

1、创建站点配置文件/var/www/conf/主域名.conf，内容参考 Nginx配置文件模板
2、创建站点根目录/var/www/wwwroot/主域名/，并通过wget下载或使用sftp上传网站文件
3、若开启HTTPS，上传域名证书文件至/var/www/wwwssl/主域名/主域名.pem，上传证书密钥文件至/var/www/wwwssl/主域名/主域名.key
4、执行systemctl reload nginx，若有提示信息无法启动，执行nginx查看错误信息进行修改
