nginx学习：配置文件及其组成

一：配置文件

etc是linux系统放置核心配置的文件夹

/etc/logrotate.d/nginx 配置文件 用于nginx日志轮转，logrotate服务的日志切割

/etc/nginx  目录配置文件  nginx的主要配置文件

/etc/nginx/nginx.conf 主要配置文件  nginx启动会读取的配置文件

/etc/nginx/conf.d 主要配置文件

/etc/nginx/conf.d/default/conf 主要配置文件  默认安装好之后，server加载读取的配置文件

/etc/nginx/nginx.conf

vim nginx,conf

user  nginx;

第一部分：全局块 配置运行nginx服务器组，允许产生worker process数，进程pid存放路径、日志存放路径以及配置文件的引入
worker_processes  1;   # nginx服务器并发处理服务的关键配置，值越大，可以支持并发处理量就越多，但是会受到硬件、软件等设备的制约

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;



第二部分：events块：主要影响nginx服务器与用户的网络连接，常用的设置包括是否开启很多对worker process下的网络连接进行序列化，是否允许同时接受多个网络请求，选取那种事件驱动模型来处理请求，
每个worker process可以同时支持的最大连接数等。1024表示最大连接数位1024个，这部分的配置对nginx的性能影响较大，在实际中应该灵活配置。
events {
    worker_connections  1024;
}

第三部分：http块：nginx配置里面配置最频繁的部分，代理、缓存和日志等绝大多数功能和第三方模块的配置都在这里。http块包括了：http全局块和server块
http全局块
http {
    include       /etc/nginx/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  /var/log/nginx/access.log  main;

    sendfile        on;

   #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

server块
默认的文件里面没有  nginx version: nginx/1.16.1 猜测这个版本里面需要自己配置

    include /etc/nginx/conf.d/*.conf;
}

 server的配置在conf.d里面的default.conf里面，启动后自己默认加载

server {
    listen       80;
    server_name  localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/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   /usr/share/nginx/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;
    #}
}

二：真实项目中nginx.conf配置

user root;
worker_processes  1;

events {
    worker_connections  1024;
}


http {

    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;

    #设置允许发布内容为8M
    client_max_body_size 20M;
    client_body_buffer_size 256k;
