这篇文章主要为大家展示了"linux如何禁止频繁访问的ip访问nginx"，内容简而易懂，条理清晰，希望能够帮助大家解决疑惑，下面让小编带领大家一起研究并学习一下"linux如何禁止频繁访问的ip访问nginx"这篇文章吧。

实验环境

版本：redhat6.5
ip:172.16.1.100,172.16.10
软件：nginx

172.16.1.10部署nginx

[root@localhost tools]# lsnginx-1.11.2.tar.gz[root@localhost tools]# yum  install gcc gcc-c++ make automake autoconf libtool pcre* zlib openssl openssl-devel[root@localhost tools]# tar xf nginx-1.11.2.tar.gz [root@localhost tools]# lsnginx-1.11.2  nginx-1.11.2.tar.gz[root@localhost tools]# cd nginx-1.11.2[root@localhost nginx-1.11.2]# lsauto  CHANGES  CHANGES.ru  conf  configure  contrib  html  LICENSE  man  README  src[root@localhost nginx-1.11.2]# ./configure[root@localhost nginx-1.11.2]# make[root@localhost nginx-1.11.2]# make install

测试nginx服务

[root@localhost ~]# curl -I 172.16.1.100HTTP/1.1 200 OKServer: nginx/1.11.2Date: Mon, 17 Aug 2020 09:36:29 GMTContent-Type: text/htmlContent-Length: 15Last-Modified: Mon, 17 Aug 2020 09:36:19 GMTConnection: keep-aliveETag: "5f3a4f93-f"Accept-Ranges: bytes

nginx 可以正常访问。
接下来，假设172.16.1.100是黑客主机，频繁访问nginx服务

模拟172.16.1.100访问10次172.16.1.10

172.16.1.100

查看nginx日志

172.16.1.10

[root@localhost ~]# tail /usr/local/nginx/logs/access.log172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"172.16.1.100 - - [26/Jul/2020:05:58:24 +0800] "GET / HTTP/1.0" 200 612 "-" "ApacheBench/2.3"

由此可见，一秒钟之内172.16.1.100访问了nginx10次，接下来禁止掉这个问题ip

通过iptables限制ip访问

172.16.1.10

[root@localhost ~]# iptables -I INPUT -s 172.16.1.100 -ptcp --dport 80 -j DROP

172.16.1.100

[root@localhost ~]# curl 172.16.1.10curl: (7) Failed connect to 172.16.1.10:80; 连接超时

此时172.16.1.100再也不能访问nginx

nginx配置文件限制

172.16.1.10

172.16.1.100

[root@localhost ~]# curl -I 172.16.1.10HTTP/1.1 403 ForbiddenServer: nginx/1.11.2Date: Sat, 25 Jul 2020 23:12:06 GMTContent-Type: text/htmlContent-Length: 169Connection: keep-alive
