scan.startup.mode 设置为 'initial'，以从表的初始状态开始读取数据，然后再进行增量同步
将其设置为 'latest-offset'，以从最新的偏移量开始读取数据，实现增量同步

假设你的 Flink Web UI 正在本地的 8081 端口运行，我们需要配置 Nginx 来做反向代理，并且开启基本认证。
打开并编辑 Nginx 配置文件，通常是
/etc/nginx/sites-available/default 或 /etc/nginx/nginx.conf，根据你的系统配置。
vim /etc/nginx/sites-available/default设置独立nginx.conf
vim /etc/nginx/conf.d/flink.conf
