3）nginx 七种状态

Active connections: 2 
server accepts handled requests
 		 4 		 4 		56 
Reading: 0 Writing: 1 Waiting: 1 

Active connections:		 # 活跃的连接数
accepts					# TCP连接总数
handle					# 成功的TCP连接数
requests				# 请求数

Reading					# 读取请求头部
Writing					# 放回给客户端的头部
Waiting					# 等待的请求数

#注意：一次tcp连接，可以发起多次请求；
keepalive_timeout  0;   #类似于关闭长连接
keepalive_timeout  65;	#最长65秒没有活动则断开连接

5.连接限制模块 ngx_http_limit_conn_module

1）语法

#设置限制的空间
		#调用模块        空间里的内容  空间=空间名字：空间大小
Syntax:	limit_conn_zone      key       zone=name:size;
Default:	—
Context:	http

#调用上面的空间
Syntax:	limit_conn zone number;
Default:	—
Context:	http, server, location

2）配置

http {
	... ...
	limit_conn_zone $remote_addr zone=conn_zone:10m;
	... ...
}

server {
	... ...
	#设置共享内存区域和设置最大允许连接数。当超过此限制时，服务器将返回 错误 以回复请求。
	limit_coon conn_zone 1;
}

6.请求限制模块 ngx_http_limit_req_module

1）语法

#设置限制请求的空间
		#模块         空间里保存的内容  空间=空间名称：大小	速率 1r/s
Syntax:	limit_req_zone      key         zone=name:size      rate=rate [sync];
Default:	—
Context:	http

#调用上面空间
Syntax:	limit_req zone=name [burst=number] [nodelay | delay=number];
Default:	—
Context:	http, server, location

2）配置

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

server {
    listen 80;
    server_name www.host1.com;
    charset 'utf-8';

    location / {
        root /codehost1;
        index index.html;
        limit_req zone=req_zone;
        limit_req_status 412;
    }

    location /download {
        root /codehost1;
        autoindex on;
        autoindex_exact_size off;
        autoindex_localtime on;
        allow 10.0.0.0/24;
        deny all;
        auth_basic "please input password!";
        auth_basic_user_file /etc/nginx/conf.d/auth_basic;
    }

    location /status {
        stub_status;
    }
}

3）测试请求限制

[root@web02 conf.d]#

Nginx location

使用Nginx Location可以控制访问网站的路径,但一个server可以有多个location配置, 多个location的优先级该如何区分

1.语法

Syntax:	location [ = | ~ | ~* | ^~ | / ] uri { ... }
		location @name { ... }
Default:	—
Context:	server, location

2.location匹配符

匹配符匹配规则优先级
=精确匹配1
^~以某个字符串开头2
~区分大小写的正则匹配3
~*不区分大小写的正则匹配4
/通用匹配，任何请求都会匹配到5

3.验证location匹配顺序

[root@web02 conf.d]# vim testlocation.conf
server {
    listen 80;
    server_name www.linux.com;
    #location / {
    #    default_type text/html;
    #    return 200 "location /";
    #}

    location =/ {
        default_type text/html;
        return 200 "location =/";
    }

   location ~ / {
        default_type text/html;
        return 200 "location ~/";
    }

   location ^~ / {
      default_type text/html;
      return 200 "location ^~";
    }
}

4.验证访问文件

[root@web01 conf.d]# cat testserver.conf 
server {
    listen 80;
    server_name www.server.com;
	location / {
    	root /code;
	}
	 
	location ~ \.php$ {
	    root /php;
	}
	 
	location ~ \.jsp$ {
	    root /jsp;
	}
	 
	location ~* \.(jpg|gif|png|js|css)$ {
	    root /pic;
	}
	 
	location ~* \.(sql|bak|tgz|tar.gz|git)$ {
	    root /package;
	}      
}
