看报错是 attempt to write a readonly database 如何复现？

[fengzhengzhan]

谢谢大佬，感谢大佬的付出

大佬，这个网站可以挂服务器上一直运行吗？我用的ubantu16.04,我运行了之后，关闭网页，网站就不能登陆了，只能开着网页才能使用吗？

[fengzhengzhan]

nohup python -u app.py > out.log 2>&1 & 不太会ubantu，这个是长期运行的指令，把后台log输出到out.log中

不用 长期运行有多种方式，最简单的nohup、tmux/screen运行，常用的比如systemd、supervisord
