Nginx Optimizer, hide version number, modify user and Group, page cache time, change process number, and anti-theft chain

设置nginx优化隐藏版本号,修改用户和组，网页缓存时间，更改进程数，以及防盗链的代码内容

======================== Hide version numbers, modify users and groups

Method One:

Cd/opt/nginx-1.12.0/src/core

Vim Nginx.h

#define Nginx_version "1.12.0"//tamper with the version number before compiling the installation to achieve hidden effect

Method Two:

Vim/usr/local/nginx/conf/nginx.conf

Server_tokens off; Add or modify

Vim/usr/local/nginx/conf/nginx.conf

User Nginx Nginx; Add directly

Add users and groups directly when compiling the installation

PS aux | grep nginx

The main process is created by the root account, and the child process is created by Nginx

=====================网页缓存时间，等待超时，更改进程数

Vim/usr/local/nginx/conf/nginx.conf

Location ~. (Gif|jepg|png|bmp|ico) $ {
root/var/www/benet.com;
Expires 1d; Cache a Day
}

Add a wait timeout in parentheses in the HTTP protocol
Keepalive_timeout 65 180; Whichever is the following number
Client_header_timeout 80;
Client_body_timeout 80;

Modify or add the number of processes directly at the beginning of the file
Worker_processes 2;

Events {
Worker_connections 4096;
}

Worker_processes 2; 2 sub-processes per CPU
Worker_connections 4096; Each subprocess processes 4,096 requests

==========================压缩设置

Vim/usr/local/nginx/conf/nginx.conf
gzip on;
Gzip_buffers 4 64k;
Gzip_http_version 1.1;
Gzip_comp_level 2;
Gzip_min_length 1k;
Gzip_vary on;
Gzip_types text/plain text/javascript application/x-javascript text/css text/xml

Application/xml Applicatin/xml+rss;
Turn on gzip compression
Compress 4 packets per package 64k
Identify the HTTP protocol version, which defaults to 1.1
The compression level of gzip is 2
Compress up to 1KB
Let the front-end cache server cache gzip-compressed pages
adding compression function parameters

=================================== Anti-theft chain
If an anti-theft chain is required in the set of virtual host servers, add the content to the appropriate virtual host settings in parentheses
Vim/usr/local/nginx/conf/nginx.conf

 location ~* \.(gzip|gif|swf)$ {    valid_referers none blocked *.benet.com benet.com;        if ( $invalid_referer ) {        rewrite ^/ http://www.benet.com/error.png;    }    }重新添加防盗链规则
