[nginx]简单内容管理系统的spring项目的nginx.conf配置文件的注释理解

user www-data;
worker_processes auto;
pid /run/nginx.pid;

# user nginx nginx; nginx user and group
# worker_processes; work processes number, always 2 times to cpu
# pid; pid=process IDentifier
# pid /run/nginx.pid; the pid storage path

events {
   worker_connections 768;
   # multi_accept on;

   # 每个worker_process工作进程的最大连接数量
   # 根据硬件调整，和前面worker_process工作进程配合起来用，尽量大，但是别把cpu跑到100%就行
   # 每个进程允许的最多连接数，理论上每台nginx服务器的最大连接数为worker_processes*worker_connections
}

# 设定http服务器，利用它的反向代理功能提供负载均衡支持
http {

   ##
   # Basic Settings基础配置
   ##

   sendfile on;
   tcp_nopush on;
   tcp_nodelay on;
   keepalive_timeout 65;
   types_hash_max_size 2048;
   # server_tokens off;

   # server_names_hash_bucket_size 64;
   # server_name_in_redirect off;

   # sendfile on; 指定 nginx 是否调用sendfile 函数（zero copy 方式）来输出文件，对于普通应用，必须设为on
   # 如果用来进行下载等应用磁盘IO重负载应用，可设置为off，以平衡磁盘与网络IO处理速度，降低系统uptime
   # tcp_nopush on; 允许或禁止使用socket的TCP_CORK的选项，此选项仅在使用sendfile的时候使用

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

    # include /etc/nginx/mime.types; 设定mime类型，类型由mime.type文件定义

   ##
   # SSL SettingsSSL配置
   ##

   ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
   ssl_prefer_server_ciphers on;

   ##
   # Logging Settings日志配置
   ##

   access_log /var/log/nginx/access.log;
   error_log /var/log/nginx/error.log;

　　# access_log 用了log_format指令设置了日志格式之后，需要用access_log指令指定日志文件的存放路径
　　# error_log 错误日志存放路径

    ##
    # cache缓存配置
    ##

    ##proxy_cache_path /usr/local/cache inactive=60m keys_zone=test:10m max_size=1g;
    ##proxy_ignore_headers Cache-Control Expires;

　　#proxy_cache_path 设置内存缓存空间大小为10MB，60分钟没有被访问的内容自动清除，硬盘缓存空间大小为1GB

   ##
   # Gzip Settings压缩包配置
   ##

   gzip on;
   gzip_disable "msie6";

   # gzip_vary on;
   # gzip_proxied any;
   # gzip_comp_level 6;
   # gzip_buffers 16 8k;
   # gzip_http_version 1.1;
   # gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

   ##
   # Virtual Host Configs虚拟host配置
   ##

   include /etc/nginx/conf.d/*.conf;
   include /etc/nginx/sites-enabled/*;
}


#mail {
#  # See sample authentication script at:
#  # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript
# 
#  # auth_http localhost/auth.php;
#  # pop3_capabilities "TOP" "USER";
#  # imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
#  server {
#     listen     localhost:110;
#     protocol   pop3;
#     proxy      on;
#  }
# 
#  server {
#     listen     localhost:143;
#     protocol   imap;
#     proxy      on;
