keepalive_timeout
http 有一个 keepalive 模式，它演讲 webserver 正在处置惩罚完一个乞求后抛却那个 tcp 毗连的翻开形态。若接管到来自客户真个其余乞求，办事端会使用那个已被洞开的联接，而没有须要再创立一个毗连。
http keep-alive, 網頁的每一一個請供皆是http (圖片, css等), 而挨開http 請供是要先创立tcp 連接, 而假定一個頁里每一個請供皆要挨開及關閉一個tcp 連接便會作成資源的浪費. keepalive_timeout 即是當一個http 請供实现, 其tcp 連接會存留高來的時間, 要是這時有另外一個http 請供過來, 會複用這個tcp 連接, 假定再沒有新的請供過來, 才會關閉其tcp連接

send_timeout :领送数据至客户端超时, 默许60s, 假如延续的60s内客户端不支到1个字节, 联接洞开
proxy_connect_timeout: nginx取upstream server的毗连超时光阴
proxy_read_timeout: nginx接受upstream server数据超时, 默许60s, 如何持续的60s内不支到1个字节, 毗连洞开
proxy_send_timeout: nginx领送数据至upstream server超时, 默许60s, 假定持续的60s内不领送1个字节, 毗邻敞开
so_timeout:
當用戶跟server開啟了tcp connection --> 一段長時間這個connection 沒traffic (so_keepalive timeout) --> server 發没探測包望用戶能否還具有 --> 若探測包沒归, 則關閉tcp connection
so_keepalive=on|off|[keepidle]:[keepintvl]:[keepcnt]so_keepalive=30m::10
will set the idle timeout (tcp_keepidle) to 30 minutes, leave the probe interval (tcp_keepintvl) at its system default, and set the probes count (tcp_keepcnt) to 10 probes.以上三个参数只能利用一个，不克不及异时应用， 歧so_keepalive=on, so_keepalive=off或者者so_keepalive=30s::(显示等候30s不数据报文领送探测报文)
以上等于Nginx timeout超时怎样设备的具体形式，更多请存眷萤水红IT仄台此外相闭文章！
