nginx.conf 介绍：

基本配置：

user  nginx;  #配置worker进程运行用户
    
    worker_processes  1;  #配置工程进程数目，根据硬件配置，一般是和CPU数量一致，或者CPU数量的2倍，能达到最佳性能
    
    
    
    error_log  /var/log/nginx/error.log warn;  # 配置全局错误日志文件以及配置级别 [ debug | info | notice | warn | error | crit ] 
    
    pid        /var/run/nginx.pid;  #配置进程pid文件
    
    
    
    
    
    关于日志级别：
    
    在配置nginx.conf 的时候，有一项是指定错误日志的，默认情况下你不指定也没有关系，因为nginx很少有错误日志记录的。但有时出现问题时，是有必要记录一下错误日志的，方便我们排查问题。
    
    error_log 级别分为 debug, info, notice, warn, error, crit  默认为crit, 该级别在日志名后边定义格式如下：
    
    error_log  /your/path/error.log crit;  
    
    crit 记录的日志最少，而debug记录的日志最多。如果你的nginx遇到一些问题，比如502比较频繁出现，但是看默认的error_log并没有看到有意义的信息，那么就可以调一下错误日志的级别，当你调成error级别时，错误日志记录的内容会更加丰富。

events 配置：

events 是配置工作模式和连接数
    
     
    
    events {
    
        worker_connections  1024;  # 配置每个worker进程连接数上限
    
    }
    
     
    
    说明：nginx支持得总连接数=worker_processes * worker_connections

http基本配置：

配置http服务器

配置http服务器
    
    http {
    
        include       /etc/nginx/mime.types;  # 配置nginx支持哪些多媒体类型
    
        default_type  application/octet-stream; #默认文件类型
    
       
    
        #配置日志格式
    
        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;  #配置访问日志  ，并使用上面的格式
    
    
    
        sendfile        on; # 开启高效文件传输模式
    
        #tcp_nopush     on; #开启防止网络阻塞模式
    
    
    
        keepalive_timeout  65; #长连接超时时间，单位秒
    
    
    
        #gzip  on;  #开启gzip压缩输出
    
    
    
        include /etc/nginx/conf.d/*.conf;
    
    }

配置server服务器；可以多个

配置server服务器；可以多个；
    
     
    
    server {

        server_name  localhost;  # 配置服务名
    
     
    
        #charset koi8-r;  #配置字符集
    
        #access_log  /var/log/nginx/host.access.log  main;  #配置本虚拟主机访问日志
    
     
    
       # 匹配/请求 ，/是根路径请求，会被该location匹配到并且处理
    
        location / {
    
            root   /usr/share/nginx/html;  #root是配置服务器的默认网关根目录位置
    
            index  index.html index.htm; #配置首页文件的名称
    
        }
    
     
    
        #error_page  404              /404.html; #配置404页面
