今天有个人问我,nginx怎么限制ip连接数,突然想不起来了,年龄大了,脑子不怎么好使了。还要看一下配置才想起了。那个人又问我,你测试过的吗?一下子把我问蒙了,我真没测试过了,也不知道启作用了没有。下面我做了一下测试。以前用apache的时候到是做过测试,apache怎么限制ip数,请参考:利用apache限制IP并发数和下载流量控制
1,配置nginx.conf
http{ ............. limit_zone one $binary_remote_addr 10m; //我记得默认配置就有,只不过是注释掉了,如果没有加一下 .............. server{ ................. location { ......... limit_conn one 20; //连接数限制 limit_rate 500k; //带宽限制 ........ } ................. } ............. } [root@localhost nginx]# /etc/init.d/nginx reload //重新加载
2,测试限制ip连接数
[root@localhost nginx]# webbench -c 100 -t 2 http://127.0.0.1/index.php Webbench - Simple Web Benchmark 1.5 Copyright (c) Radim Kolar 1997-2004, GPL Open Source Software. Benchmarking: GET http://127.0.0.1/index.php 100 clients, running 2 sec. Speed=429959 pages/min, 2758544 bytes/sec. Requests: 14332 susceed, 0 failed. [root@localhost nginx]# cat /var/log/nginx/access.log|grep 503 |more //这样的数据有很多,最好加个more或者less 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - 127.0.0.1 - - [25/Apr/2012:17:52:21 +0800] "GET /index.php HTTP/1.0" 503 213 "-" "WebBench 1.5" - ..............................................................................................
通过以上测试,可以得出限制ip连接数是没有问题的,但是限制带宽看不出来,说实话这个不好测试,所以就没测试了。
