配置文件里涉及相对目录配置时，都是都是相对于/etc/nginx/

nginx 默认配置

/etc/nginx/nginx.conf

  1. user  nginx;
  2. worker_processes  1;
  4. error_log  /var/log/nginx/error.log warn;
  5. pid        /var/run/nginx.pid;
  8. events {
  9.     worker_connections  1024;
  10. }
  13. http {
  14.     include       /etc/nginx/mime.types;
  15.     default_type  application/octet-stream;
  17.     log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
  18.                       '$status $body_bytes_sent "$http_referer" '
  19.                       '"$http_user_agent" "$http_x_forwarded_for"';
  21.     access_log  /var/log/nginx/access.log  main;
  23.     sendfile        on;
  24.     #tcp_nopush     on;
  26.     keepalive_timeout  65;
  28.     #gzip  on;
  30.     include /etc/nginx/conf.d/*.conf;
  31. }

/etc/nginx/conf.d/default.conf

  1. server {
  2.     listen       80;
  3.     listen  [::]:80;
  4.     server_name  localhost;
  6.     #charset koi8-r;
  7.     #access_log  /var/log/nginx/host.access.log  main;
  9.     location / {
  10.         root   /usr/share/nginx/html;
  11.         index  index.html index.htm;
  12.     }
  14.     #error_page  404              /404.html;
  16.     # redirect server error pages to the static page /50x.html
  17.     #
  18.     error_page   500 502 503 504  /50x.html;
  19.     location = /50x.html {
  20.         root   /usr/share/nginx/html;
  21.     }
  23.     # proxy the PHP scripts to Apache listening on 127.0.0.1:80
  24.     #
  25.     #location ~ \.php$ {
  26.     #    proxy_pass   http://127.0.0.1;
  27.     #}
  29.     # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
  30.     #
  31.     #location ~ \.php$ {
  32.     #    root           html;
  33.     #    fastcgi_pass   127.0.0.1:9000;
  34.     #    fastcgi_index  index.php;
  35.     #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
  36.     #    include        fastcgi_params;
  37.     #}
  39.     # deny access to .htaccess files, if Apache's document root
  40.     # concurs with nginx's one
  41.     #
  42.     #location ~ /\.ht {
  43.     #    deny  all;
  44.     #}
  45. }
