Nginx配置记录

一、nginx默认配置

#user  nobody;worker_processes  1;#error_log  logs/error.log;#error_log  logs/error.log  notice;#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {    worker_connections  1024;}http {    include       mime.types;    default_type  application/octet-stream;    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '    #                  '$status $body_bytes_sent "$http_referer" '    #                  '"$http_user_agent" "$http_x_forwarded_for"';    #access_log  logs/access.log  main;    sendfile        on;    #tcp_nopush     on;    #keepalive_timeout  0;    keepalive_timeout  65;    #gzip  on;    server {        listen       80;        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {            root   html;            index  index.html index.htm;        }        #error_page  404              /404.html;        # redirect server error pages to the static page /50x.html        #        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }        # proxy the PHP scripts to Apache listening on 127.0.0.1:80        #        #location ~ \.php$ {        #    proxy_pass   http://127.0.0.1;        #}        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000        #        #location ~ \.php$ {        #    root           html;        #    fastcgi_pass   127.0.0.1:9000;        #    fastcgi_index  index.php;        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;        #    include        fastcgi_params;        #}        # deny access to .htaccess files, if Apache's document root        # concurs with nginx's one        #        #location ~ /\.ht {        #    deny  all;        #}    }    # another virtual host using mix of IP-, name-, and port-based configuration    #    #server {    #    listen       8000;    #    listen       somename:8080;    #    server_name  somename  alias  another.alias;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}    # HTTPS server    #    #server {    #    listen       443 ssl;    #    server_name  localhost;    #    ssl_certificate      cert.pem;    #    ssl_certificate_key  cert.key;    #    ssl_session_cache    shared:SSL:1m;    #    ssl_session_timeout  5m;    #    ssl_ciphers  HIGH:!aNULL:!MD5;    #    ssl_prefer_server_ciphers  on;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}}

二、配置

user  root; #配置用户或者组
worker_processes  1; #允许生成的进程数


#error_log  logs/error.log;  #日志的路径,级别为:debug|info|notice|warn|error|crit|alert|emerg
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;


#pid        logs/nginx.pid; #指定nginx进程运行文件存放地址




events {
    accept_mutex on; #设置网络连接序列化,默认为on.可以防止惊群现象发生。
#惊群现象：多线程下等待同一个socket事件，当这个事件发生时，这些线程被同时唤醒，就是惊群现象
    multi_accept on;    #设置一个进程是否同时接收多个网络链接，默认为off


    worker_connections  1024;#最大连接数
}

http {
    include       mime.types;  #文件的扩展名与文件类型的映射表
    default_type  application/octet-stream;#默认文件类型,默认为text/plain


    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';


    #access_log  logs/access.log  main;


    sendfile        on; #允许sendfile方式传输文件,默认为off
    #tcp_nopush     on;


    #keepalive_timeout  0; 
    keepalive_timeout  65; #连接超时时间,默认为75s


    #gzip  on;
    client_max_body_size    1000m; #设置文件最大上传数，默认为1M


    server {
        listen       80; #监听的端口
listen       81;
        server_name   www.pop.com  pop.com; #监听的地址

        access_log  logs/access.log  main;
deny 42.120.145.0/24;  #拒绝的端口

         location / {
  #root  /data1/webserver/upload/update/;
   proxy_set_header  Host $host;
            proxy_set_header  X-Real-IP  $remote_addr;
            proxy_set_header  X-Forwarded-For $remote_addr;
            proxy_pass        http://127.0.0.1:8080;
  client_max_body_size    1000m;
        }


 location /qrcode {
       autoindex on;
            root   html; 
            index  index.html index.htm;
        }


   }
   server {
       listen       8088;
       server_name   47.93.115.66;
deny 42.120.145.0/24;
        location / {
  #root  /data1/webserver/upload/update/;
   proxy_set_header  Host $host;
           proxy_set_header  X-Real-IP  $remote_addr;
           proxy_set_header  X-Forwarded-For $remote_addr;
           proxy_pass        http://127.0.0.1:8080;
  client_max_body_size    1000m;
       }
       


 location /qrcode {
      autoindex  on;
            root   html;
            index  index.html index.htm;
        }


   }
   server {
        listen       80;
        server_name   file.pop.com;


        #charset koi8-r;


        #access_log  logs/host.access.log  main;


         location / {
            root   /data1/webserver/upload/;
        }
   }
   server {
        listen       8084;
        server_name   47.93.115.66;


        #charset koi8-r;


        #access_log  logs/host.access.log  main;


         location / {
            root   /data1/webserver/upload/;
        }
   }
   server {
listen       80;

        server_name   app.pop.com;

        #charset koi8-r;
        #
        #
        #
        #        #access_log  logs/host.access.log  main;
        #
         location / {
        
             root   /data1/webserver/upload/;
        
          }


   }

三、Nginx常用命令

1、启动nginx

./nginx -c   /usr/local/nginx/nginx.conf

2、关闭nginx

先查看nginx进程号：ps -ef |grep nginx

从容关闭nginx: kill -QUIT  nginx主进程号

立刻关闭:kill -TERM  nginx主进程号

强制关闭：kill -9  nginx主进程号
