Nginx服务优化配置方案

1、expires缓存模块

具体配置可参考官方文档 http://nginx.org/en/docs/http/ngx_http_headers_module.html#expires

[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.jpgHTTP/1.1 200 OKServer: nginx/1.13.9Date: Mon, 05 Mar 2018 04:08:41 GMTContent-Type: image/jpegContent-Length: 48561Last-Modified: Wed, 29 Nov 2017 08:16:39 GMTConnection: keep-aliveETag: "5a1e6ce7-bdb1"Expires: Mon, 12 Mar 2018 04:08:41 GMTCache-Control: max-age=604800Accept-Ranges: bytes

2、Nginx压缩模块（gzip）

配置压缩模块

[root@localhost vhost]# vi www.vhostsserver {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;}

检查语法、重启服务

[root@localhost vhost]# /application/nginx/sbin/nginx -tnginx: the configuration file /application/nginx-1.10.1/conf/nginx.conf syntax is oknginx: configuration file /application/nginx-1.10.1/conf/nginx.conf test is successful[root@localhost vhost]# /application/nginx/sbin/nginx -s reload[root@localhost vhost]# cd /web/www/[root@localhost www]# lltotal 12-rw-r--r--. 1 root root 20 Sep 26 07:00 index.html-rw-r--r--. 1 root root 5798 Sep 19 06:46 mysql.jpg[root@localhost www]# rzrz waiting to receive.Starting zmodem transfer.
