Nginx optimization-process management, web page compression, hotlink protection

Main points of content:

Process Management of nginx Optimization

Nginx optimized Web Page Compression

Hotlink protection optimized by nginx

Experimental environment:

On the basis of compiling and installing nginx

I. process management of nginx optimization

1. Time-out access:

Vim / usr/local/nginx/conf/nginx.conf http {... keepalive_timeout 65 180; # whichever is the latter. You can set client_header_timeout 80 at http\ server\ locati on; # the timeout of waiting for the client to send the request header will send 408 error client_body_timeout 80; # set the timeout of the client input request body.}

2. Change the number of processes

Ps aux | grep nginx # # View the current number of processes. A main process contains a child process

A, add cpu

Add cpu in the lower right corner of the virtual machine

B. Restart the service

Init 6

C. Check the cpu situation

Cat / proc/cpuinfo

D. Modify the configuration file

Vim / usr/local/nginx/conf/nginx.confworker_processes 2; # worker process is 2 (modify the same or twice the number of cores) worker_cpu_affinity 01 10; # average allocation number 1 2 (each process is handled by a different cpu)

II. Web page compression

1. Configure compression in the configuration file

Vim / usr/ local/nginx/ conf/nginx. Conf gzip on; # remove # enable gzip compression function gzip_min_length 1k; # compression threshold gzip_buffers 4 16k; # buffer size 4 16k buffer size gzip_http_version 1.1; # compressed version wood gzip_comp_level 6 # Compression ratio, minimum 1, fast processing speed, slow transmission speed, 9 maximum compression ratio, slow processing speed, fast transmission speed gzip_types text/plain application/x-javascript text/css image/jpg image/jpeg image/png image/gif application/xml text/javascript application/x-httpd-php application/javascript applicationion/json; gzip_disable "MSIE [1-6]\." # configure to disable gzip condition and support regular, which means that gzip gzip_vary on; is not enabled below ie6. # choosing to support very header allows the front-end cache server to cache gzip-compressed pages

2. Insert an jpg image into the home page of the site for testing.

Cp / error / usr/local/nginx/htmlvim index.html

Third, hotlink protection optimized by nginx

Add hotlink jump settings to the nginx configuration file

There are two configuration methods:

First kind

Vim / usr/local/nginx/conf/nginx.conf location ~ *\. (jpg | gif | swf) ${# the file type that requires hotlink protection resources valid_referers none blocked * .lulu.com; if ($invalid_referer) {rewrite ^ / # if someone illegally steals the resources, return a hotlink protection map}}

The second kind:

Location / img/ {# img is the relative directory, which is the img directory valid_referers none blocked server_names * .lulu.com under the html directory; # the domain name or IP if ($invalid_referer) {rewrite ^ / https://cache.yisu.com/upload/information/20200309/28/13243.jpg; allowed to access this directory }}
