Nginx サービスの構成を最適化する方法

1. キャッシュ モジュールの有効期限が切れます

具体的な設定については、公式ドキュメントを参照してください

[root@cairui conf]# cat nginx.conf | egrep -v "#|^$"
user nginx;
worker_processes 1;
events {
  worker_connections 1024;
}
http {
  include    mime.types;
  default_type application/octet-stream;
  sendfile    on;
  keepalive_timeout 65;
  server {
    listen    80;
    server_name localhost;
    location / {
      root  html;
      index index.html index.htm;
    }
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|js|html|htm|css)$ {
   log_not_found off;
   expires 7d ;
   access_log off;
   proxy_store on;
   proxy_store_access user:rw group:rw all:rw;
}
    error_page  500 502 503 504 /50x.html;
    location = /50x.html {
      root  html;
    }
  }
}

[root@cairui conf]# curl -i http://120.25.255.87/1.jpg
http/1.1 200 ok
server: nginx/1.13.9
date: mon, 05 mar 2018 04:08:41 gmt
content-type: image/jpeg
content-length: 48561
last-modified: wed, 29 nov 2017 08:16:39 gmt
connection: keep-alive
etag: "5a1e6ce7-bdb1"
expires: mon, 12 mar 2018 04:08:41 gmt
cache-control: max-age=604800
accept-ranges: bytes

2. nginx 圧縮モジュール (gzip)

圧縮モジュールを構成します

[root@localhost vhost]# vi www.vhosts
server {
listen 8001;
server_name 192.168.1.3;
location / {
root /web/www;
index index.html index.htm;
access_log /application/nginx/log/access_www.log commonlog;
}
location ~ .*\.(gif|jpg|jpge|png|bmp|swf)$
{
expires 3560d;
root /web/www;
}
location ~ .*\.(js|css)?$
{
expires 30d;
root /web/www;
}
gzip on; #开启压缩功能
gzip_min_length 1k; #设置允许压缩页面的最小字节数
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
}

構文を確認してサービスを再起動します

[root@localhost vhost]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.10.1/conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.10.1/conf/nginx.conf test is successful
