Nginx.conf注释版本

nginx.conf

#总体上分成三个部分构成：基本配置、events配置、HTTP配置，以下为配置详情
#------------------------基本配置-------------------------
#user  nobody; #配置worker进程运行用户
worker_processes  4; #配置工作进程数目，根据硬件调整，通常等于CPU数量或者2倍于CPU数量

#error_log  logs/error.log; #配置全局错误日志及类型，[debug | info | notice | warn | error | crit]，默认是error
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid; #配置进程pid文件

#------------------------events配置-------------------------
#配置工作模式和连接数
events {
    use epoll; # 优化参数，事件模型，提高性能
    worker_connections  1024; #配置每个worker进程连接数上限，nginx支持的总连接数就等于worker_processes * worker_connections
}

#------------------------HTTP配置-------------------------
#配置HTTP服务器，利用它的反向代理功能提供负载均衡支持
http {
    #------------------------HTTP基本配置-------------------------
    include       mime.types; #配置nginx支持哪些多媒体类型，可以在conf/mime.types查看支持哪些多媒体类型
    default_type  application/octet-stream; #默认文件类型，流类型，流类型意味着任何类型都支持

    #配置日志格式，$vars 是内部变量
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #配置access.log日志及存放路径，并使用上面定义的main日志格式
    #access_log  logs/access.log  main;

    sendfile        on; #优化参数：开启高效文件传输模式
    tcp_nopush     on; #优化参数：防止网络阻塞

    #keepalive_timeout  0; 
    keepalive_timeout  65; #长连接超时时间，单位：毫秒

    gzip  on; #开启gzip压缩输出
    #------------------------HTTP_多server配置-------------------------
    server {
        listen       80; #监听端口
        server_name  localhost; #配置服务名

        #charset utf-8; #配置字符集

        #access_log  logs/host.access.log  main; #配置本虚拟主机的访问日志

        #默认的斜杠/的请求，当访问路径中有斜杠/，会被该location匹配到并进行处理
        location / {
            root   html; #root是配置服务器默认网站根目录位置，默认nginx安装主目录下的html
            index  index.html index.htm; #配置首页文件的名称
        }

        #error_page  404              /404.html; #配置404错误页

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html; 配置50x错误页面; = 号，指的是精确匹配
        location = /50x.html {
            root   html;
        }

        # 这是一个PHP的配置
        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        # 
        # 一旦匹配php的文件，就转发到 127.0.0.1 默认80端口
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # 这也是一个转发例子
        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        # 当后缀是php转发到 flastcgi服务器
        #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;
        #}

        # 禁止访问，用户保护一些路径资源
        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }

    # 另一个server的配置。可以平行配置很多，一般大厂会在这里配置几百个
    # 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加密传输的例子
    # HTTPS server
    #
    #server {
    #    listen       443 ssl; # https默认是443端口，http默认是80端口
    #    server_name  localhost;

    #    ssl_certificate      cert.pem; # 证书需要购买
    #    ssl_certificate_key  cert.key; # 证书key需要购买才有

    #    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;
    #    }
    #}

}
