Question

所以我有一个需要与gunicorn --worker-class eventlet一起运行的烧瓶应用。

但是当我在iterm2窗格中启动这样的app时，当我调整窗格大小时（发送绞盘信号），工作人员崩溃了：

供参考： *我也在我的代码中使用grpc。 *这不会发生在我的远程centos 7服务器上，只有我的mac

Answer 1

在调整大小之前执行此操作。

import signal
signal.signal(signal.SIGWINCH, signal.SIG_IGN)

我认为它应该包含在gunicorn初始化中。

当使用eventlet作为工人类时，在绞车信号的gunicorn工作者崩溃
