Nginx設定檔nginx.conf解讀

這篇文章主要介紹了關於Nginx設定檔nginx.conf解讀，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下

開啟一個全新配置的nginx的nginx.conf檔案，檔案結構大概是這個樣子：

#user  nobody;worker_processes  1;#error_log  logs/error.log;#error_log  logs/error.log  notice;#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {    worker_connections  1024;}http {    include       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  logs/access.log  main;    sendfile        on;    #tcp_nopush     on;    #keepalive_timeout  0;    keepalive_timeout  65;    #gzip  on;    server {        listen       80;        server_name  localhost;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {            root   html;            index  index.html index.htm;        }        #error_page  404              /404.html;        # redirect server error pages to the static page /50x.html        location = /50x.html {            root   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;        #}    }    #    #server {    #    listen       8000;    #    listen       somename:8080;    #    server_name  somename  alias  another.alias;    #    location / {    #        root   html;    #        index  index.html index.htm;    #    }    #}    # HTTPS server    #    #server {    #    listen       443 ssl;    #    server_name  localhost;    #    ssl_certificate      cert.pem;    #    ssl_certificate_key  cert.key;    #    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;    #    }    #}}

一大堆代碼看起來眼花繚亂，其實並不複雜，我們來看精簡版的：

# 全域區worker_processes  1;  # 有1個工作的worker子進程#可以自行修改,但太大會造成相互爭奪CPU,一般來說：子進程數 = CPU數 * 核心數# 配置nginx的串連特性events {    worker_connections  1024; # 1個worker子進程能同時允許的最大串連數}# http伺服器主要段http {    # 設定mime類型,類型由mime.types檔案定義    include       mime.types;    default_type  application/octet-stream;    sendfile        on; # 是否調用sendfile來輸出檔案    keepalive_timeout  65; # 連線逾時時間    # 虛擬機器主機段    server {        listen       80; # 監聽連接埠        server_name  localhost; # 監聽主機\網域名稱\連接埠    # 定義訪問響應        location / {            root   html; # 根目錄定位            index  index.html index.htm; # 預設訪問頁面定位        }    # 定義錯誤提示頁面        location = /50x.html {            root   html;        }}
