5>.nginx支持安全认证

　　针对使用ab命令发起的简单攻击，我们可以在nginx做限制，可以设置最大并发数来加以限制，但并不推荐这样干，我们可以直接使用防护墙进行拦截。这样攻击压根就打不到nginx服务器上。

　　和httpd服务一样，nginx也支持基于用户账号认证和IP地址认证，接下来咱们就来一起来体验一下吧。

二.Nginx账户认证功能

1>.安装httpd-tools工具并创建用户名和密码

[root@node101.yinzhengjie.org.cn ~]#

5>.客户端访问nginx

　　浏览器输入:"http://node101.yinzhengjie.org.cn/login",会弹出如下图所示的对话框，输入咱们自定义的密码进行登录验证

　　如下图所示，输入正确的用户名和密码就可以正常登录啦。

　　如果没有输入正确的用户名和密码则验证错误，无法看到我们预定义的网页，如下图所示。

三.Nginx 四层访问控制

1>.编辑子配置文件

[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf.d/auth.conf 
server {
    listen 80;
    server_name node101.yinzhengjie.org.cn;

    location / {
        root /yinzhengjie/data/web/nginx/html;
        index index.html;
    }

    location /login {
        root /yinzhengjie/data/web/nginx;
        index index.html;
        deny 172.30.1.108;　　　　　　　　　　#咱们可以拒绝某个IP访问
        allow 172.30.1.0/24;　　　　　　　　 #咱们可以设置运行某个网段访问
        allow 2001:0db8::/32;　　　　　　　　#当然，也支持IPV6地址限制哟~
        deny all;　　　　　　　　　　　　　　　#上面做了允许小部分IP地址后，其它的默认都被拒绝了，因为匹配规则是自上而下进行匹配，一旦匹配后就不在往下继续匹配。
    }
}
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]#

2>.重新加载nginx的配置文件

[root@node101.yinzhengjie.org.cn ~]# ps -ef | grep nginx | grep -v grep
root      2840     1  0 09:37 ?        00:00:00 nginx: master process nginx
nginx     2879  2840  0 09:42 ?        00:00:04 nginx: worker process
nginx     2880  2840  0 09:42 ?        00:00:01 nginx: worker process
nginx     2881  2840  0 09:42 ?        00:00:02 nginx: worker process
nginx     2882  2840  0 09:42 ?        00:00:02 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# nginx -s reload
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]# ps -ef | grep nginx | grep -v grep
root      2840     1  0 09:37 ?        00:00:00 nginx: master process nginx
nginx     3009  2840  9 10:03 ?        00:00:00 nginx: worker process
nginx     3010  2840 10 10:03 ?        00:00:00 nginx: worker process
nginx     3011  2840 10 10:03 ?        00:00:00 nginx: worker process
nginx     3012  2840 10 10:03 ?        00:00:00 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]# 
[root@node101.yinzhengjie.org.cn ~]#

3>.在IP地址为"172.30.1.108"节点*问nginx的服务被拒绝

[root@node108.yinzhengjie.org.cn ~]# hostname
node108.yinzhengjie.org.cn
[root@node108.yinzhengjie.org.cn ~]# 
[root@node108.yinzhengjie.org.cn ~]# hostname -i
172.30.1.108
[root@node108.yinzhengjie.org.cn ~]# 
[root@node108.yinzhengjie.org.cn ~]# curl -I http://node101.yinzhengjie.org.cn/login/　　　　　　　　#很显然，报错403啦，即权限被拒绝！
HTTP/1.1 403 Forbidden
Server: nginx/1.14.2
Date: Tue, 17 Dec 2019 02:05:06 GMT
Content-Type: text/html; charset=utf-8
Content-Length: 169
Connection: keep-alive
Keep-Alive: timeout=65

[root@node108.yinzhengjie.org.cn ~]# 
[root@node108.yinzhengjie.org.cn ~]#

4>.在浏览器上是可以正常访问的，如下图所示
