nginx_模块相关

 参考文档：http://shouce.jb51.net/nginx/

认证模块

        

            yum install httpd-tools -y

 

        

            Syntax:    auth_basic string | off;    如果跟string,就代表开启。

            Default:    

            auth_basic off;

            Context:    http, server, location, limit_except

            

            1、生成密码

            [root@web02 conf.d]# htpasswd -c /etc/nginx/auth chenyang

 

            2、配置加密

            auth_basic "This is Auth Basic!";

            auth_basic_user_file /etc/nginx/auth;

 

 

            在命令行中的访问方式

            [root@m01 ~]# curl -H'Host: index.test.com' http://chenyang:123456@192.168.15.8

    

 

 

 

 

 

    

Nginx状态模块

        

            location /status {

                stub_status;

            }

   

 

 

 

 

     访问控制模块

        3、禁用IP和开放IP访问

        

            allow    : 允许IP访问

            deny    ：禁止IP访问

            

            案例1：只允许192.168.15.1来访问。

                

                1、允许192.168.15.1来访问

                

                    allow 192.168.15.1;

                    

                2、禁止其他所有IP来访问

                

                    deny all;

            

server {
listen 80;
server_name localhost;
return 301 https://$host$request_uri;
allow 192.168.15.1
deny all
location / {
root html;
index index.html index.htm;
}

 

            案例2：只允许192.168.15.0来访问。

            

                

                1、允许192.168.15.0来访问

                

                    allow 192.168.15.0/24;

                

                2、禁止其他所有IP来访问

                

                    deny all;

                

server {
listen 80;
server_name localhost;
return 301 https://$host$request_uri;
allow 192.168.15.0/24;
deny all;
location / {
root html;
index index.html index.htm;
}

            案例3：要求禁止192.168.15.1来访问。

            

                1、禁止192.168.15.1来访问

                

                    deny 192.168.15.1;

                

                2、允许其他所有的IP来访问

                

                    allow all;

server {
listen 80;
server_name localhost;
return 301 https://$host$request_uri;
deny 192.168.15.1;
allow all;
location / {
root html;
index index.html index.htm;
}

            

     

 

 

 

 

 

       

        

目录索引模块

        

            # 开启目录索引

            autoindex on;

            # 格式化文件大小

            autoindex_exact_size off;

            # 输出的格式

            autoindex_format html;

            # 使用时区

            autoindex_localtime on;

      

 

 

 

  

限制连接数模块

        

            1、创建一个内存空间存放访问者的IP

            

            2、设置每一个访问者的同时连接次数

        

        6、限制请求数模块

        

            1、创建一个内存空间存放访问者的IP

            

            2、设置每一个访问者的同时请求次数

            [root@web02 conf.d]# cat game.conf

            # 创建一个叫linux的空间，主要用来存放客户端IP，大小给10M

            limit_conn_zone $remote_addr zone=linux:10m;

 

            limit_req_zone $remote_addr  zone=python:10m rate=1r/s;

 

            server {

                server_name game.test.com;

                listen 80;

                location / {

                    # 调用linux空间, 限制连接数为1

                    # limit_conn linux 1;

                    limit_req zone=python burst=5;

                    root /usr/share/nginx/html5-mario;

                    index index.html;

                }

            }

 

     

 

        知识储备：

        

            ab ： 创建请求的命令，（yum install httpd-tools -y ）

            

                -c ： 设置并发

                -n :  设置请求的总数
