是否应该从Nginx配置中删除“ keepalive_timeout”？

哪个配置/优化更好：显式限制keepalive_timeoutor或允许Nginx自行终止keepalive连接？

我已经看到有关keepalive_timeoutNginx指令的两个相互矛盾的建议。它们如下：

# How long to allow each connection to stay idle; longer values are better
# for each individual client, particularly for SSL, but means that worker
# connections are tied up longer. (Default: 65)
keepalive_timeout  20;

和

# You should remove keepalive_timeout from your formula.
# Nginx closes keepalive connections when the
# worker_connections limit is reached.

该Nginx的 文档为keepalive_timeout没有提及自动查杀，而我只看到这一建议一次，但它令我着迷。

该服务器专门提供TLS保护的连接，并且所有未加密的连接都会立即重新路由到https://同一URL 的版本。

当达到worker_connections限制时，Nginx关闭keepalive连接。

确实如此。
