nginx常用配置
2018/12/14    
########### 每个指令必须有分号结束。#################
#user administrator administrators;  #配置用户或者组,默认为nobody nobody。
#worker_processes 2;  #允许生成的进程数,默认为1
#pid /nginx/pid/nginx.pid;   #指定nginx进程运行文件存放地址
error_log log/error.log debug;  #制定日志路径,级别。这个设置可以放入全局块,http块,server块,级别以此为:debug|info|notice|warn|error|crit|alert|emerg
events {
    accept_mutex on;   #设置网路连接序列化,防止惊群现象发生,默认为on
    multi_accept on;  #设置一个进程是否同时接受多个网络连接,默认为off
    #use epoll;      #事件驱动模型,select|poll|kqueue|epoll|resig|/dev/poll|eventport
    worker_connections  1024;    #最大连接数,默认为512
}
http {
    include       mime.types;   #文件扩展名与文件类型映射表
    default_type  application/octet-stream; #默认文件类型,默认为text/plain
    #access_log off; #取消服务日志    
    log_format myFormat '$remote_addr–$remote_user [$time_local] $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for'; #自定义格式
    access_log log/access.log myFormat;  #combined为日志格式的默认值
    sendfile on;   #允许sendfile方式传输文件,默认为off,可以在http块,server块,location块。
    sendfile_max_chunk 100k;  #每个进程每次调用传输数量不能大于设定的值,默认为0,即不设上限。
    keepalive_timeout 65;  #连接超时时间,默认为75s,可以在http,server,location块。

    upstream mysvr {   
      server 127.0.0.1:7878;
      server 192.168.10.121:3333 backup;  #热备
    }
    error_page 404 https://www.baidu.com; #错误页
    server {
        keepalive_requests 120; #单连接请求上限次数。
        listen       4545;   #监听端口
        server_name  127.0.0.1;   #监听地址       
        location  ~*^.+$ {       #请求的url过滤,正则匹配,~为区分大小写,~*为不区分大小写。
           #root path;  #根目录
           #index vv.txt;  #设置默认页
           proxy_pass  http://mysvr;  #请求转向mysvr 定义的服务器列表
           deny 127.0.0.1;  #拒绝的ip
           allow 172.18.5.54; #允许的ip           
        } 
    }
}

上面是nginx的基本配置,需要注意的有以下几点:


1、1.$remote_addr 与$http_x_forwarded_for 用以记录客户端的ip地址; 2.$remote_user :用来记录客户端用户名称; 3.$time_local : 用来记录访问时间与时区;4.$request : 用来记录请求的url与http协议;


5.$status : 用来记录请求状态;成功是200, 6.$body_bytes_s ent :记录发送给客户端文件主体内容大小;7.$http_referer :用来记录从那个页面链接访问过来的; 8.$http_user_agent :记录客户端浏览器的相关信息;


2、惊群现象:一个网路连接到来,多个睡眠的进程被同事叫醒,但只有一个进程能获得链接,这样会影响系统性能。


3、每个指令必须有分号结束。
