Nginx服务优化配置

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.jpg
HTTP/1.1 200 OK
Server: nginx/1.13.9

2、Nginx压缩模块（gzip）

配置压缩模块
[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;
}
检查语法、重启服务
[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
