Nginx limit_req 限流：几行配置挡住大部分CC攻击_我的网站

　    一键部署OpenClaw        服务器CPU莫名飙高，带宽跑满，看日志全是同一个IP一秒打来几十个请求——这不是业务火了，是被CC了。

二 |     Sunny Deol’s appearance at the Border 2 teaser launch was significant for more than one reason. It was his first public outing since his father’s demise, and the moment stood out for the calm dignity with which he returned to work. His presence was understated yet impactful, showing resilience and responsibility during a difficult phase.     The actor made a striking entry at the event by arriving in full character look. Sunny was seen driving a jeep, instantly setting the tone for the war drama. The dramatic arrival added excitement to the launch and offered fans a glimpse into the intense and patriotic world of Border 2. He was joined by his co-stars Varun Dhawan and Ahan Shetty, who were seated alongside him in the jeep. The visual of the three actors together highlighted the film’s multi-starrer appeal and caught immediate attention.     During the event, Sunny Deol appeared visibly emotional while delivering one of the film’s dialogues in his iconic action-filled style and powerful voice. The moment left many in the audience moved, as the actor struggled to hold back tears, blending personal emotion with his on-screen intensity.     Watch the clip here:                                                                       View this post on Instagram          A post shared by Filmfare (@filmfare)                     The makers unveiled the first striking teaser of Border 2 on Vijay Diwas, December 16, adding symbolic weight to the launch. Directed by Anurag Singh, the film continues the legacy of honouring the bravery, sacrifice, and indomitable spirit of Indian soldiers. Staying true to the emotional and action-driven core of the original film, Border 2 promises a powerful journey filled with patriotism and courage.     The film is scheduled to release in cinemas on January 23, 2026. After the massive success of Gadar 2 in 2023, Sunny Deol earlier spoke about why Border 2 took time to come together. Speaking on Ranveer Allahbadia’s podcast, he said, “Ye hum bahut pehle karne wale the, 2015 mein. Par phir meri picture nahi chali, toh log ghabra ke nahi banana chah rahe. Ab sab bol rahe hain humey karni hai.” With Border 2, Sunny Deol returns once again in a role that reflects his long-standing association with patriotic cinema.     Also Read: Sunny Deol and Bobby Deol Share Heartfelt Moments With Fans While Honouring Father Dharmendra’s Legacy。扛CC的第一道闸门不在代码里，在Nginx的限流模块里，配置成本几乎为零。    limit_req的原理是漏桶：你设定一个速率，超速的请求直接返回503或延迟排队。先用limit_req_zone定义一个计数区，再在location里挂上limit_req，两步完事。    

# nginx.conf 的 http 块里定义限流区

    # 以客户端IP为key，10MB内存可存约16万个IP状态    # rate=10r/s 表示平均每秒最多放行10个请求    limit_req_zone $binary_remote_addr zone=req_per_ip:10m rate=10r/s;    # server 或 location 块里应用    server {    location / {    limit_req zone=req_per_ip burst=20 nodelay;    proxy_pass http://127.0.0.1:8080;    }    }    burst=20是缓冲队列长度，配合nodelay表示突发20个请求立即处理、不排队，超出就直接拒。想对登录、搜索这类昂贵接口管得更严，单独再定义一个rate=2r/s的zone挂上去就行，互不影响。    

# 对登录接口单独限流：每秒2个，突发5个
limit_req_zone $binary_remote_addr zone=login_limit:10m rate=2r/s;
 
location /login.php {
 limit_req zone=login_limit burst=5 nodelay;
 # 被限流的请求返回429而不是默认503
 limit_req_status 429;
 fastcgi_pass 127.0.0.1:9000;
}

    验证很简单：reload之后用ab压一下，ab -n 200 -c 20 https://你的域名/，看返回里有没有429或503；同时tail -f日志确认正常用户没被误伤。限流阈值别拍脑袋定，先统计自己站点的正常峰值，设成峰值的两倍左右再逐步收紧。限流是防守，如果卡死自己人就本末倒置了。
