China launches Zhuque-3, achieving its first rocket recovery on land_我的网站

???ڇ?;

一 | China launched the reusable rocket Zhuque-3 on Wednesday morning, achieving its first recovery of a rocket's first stage on land. The Zhuque-3 Y2 rocket blasted off at 7:35 a.m. (Beijing Time) from the Dongfeng commercial space innovation pilot zone in northwest China. The land-based recovery of the rocket's first stage was completed as planned, and the flight mission was a complete success. This mission followed the successful sea-based net recovery of the Long March-10B's first stage on July 10. It marked China's first successful land-based controlled recovery of a rocket's first stage using deployable landing legs, highlighting a major breakthrough in the country's reusable rocket technology. 。

　一键部署OpenClaw 做站长最怕的不是没流量，是服务器莫名其妙瘫了。Slowloris 这类慢连接攻击不发送大量请求，而是故意把连接拖住，耗光 Nginx 的 worker 进程。你的网站可能瞬间从“打不开”变成完全无响应。

应对思路很简单：给连接设置合理的超时阈值。客户端发完头部就超时、发body 也超时、整体发送还超时，三个时间窗口一收紧，攻击者就没了拖下去的空间。

二 | http { client_header_timeout 10s; #读取请求头超时时间 client_body_timeout 10s; #读取请求体超时时间 send_timeout 10s; #发送响应超时时间 keepalive_timeout 30s; #长连接保持时间 #限制单IP连接数，进一步压制慢连接 limit_conn_zone $binary_remote_addr zone=addr:10m; server { limit_conn addr 30; } } 这里的时间值不是越小越好。

三 | 如果你的接口有上传大文件的功能，client_body_timeout 可以放宽到 60 秒，甚至针对上传路径单独写一个 location。核心原则是：正常用户用不上那么长时间。配置改完后用nginx -t 检查语法，reload 平滑生效。可以用 slowhttptest 工具自己压测一下，看改成 10 秒后连接还能不能被挂住。真实业务里我习惯把这几个值默认设为 10 秒，上传接口单独放开。
