Nginx优化与防盗链

拓扑图：

Nginx优化与防盗链

推荐步骤：

1、在Centos01上安装Nginx，设置网站根目录/www使用域名​​www.huhu.com​​访问

2、在Centos02上安装DNS使用域名访问Centos01上使用域名​​www.huhu.com​​​访问，Centos03使用yum安装apache使用域名​​www.huyan.com​​访问

3、在​​www.huhu.com域名的网站隐藏Nginx​​版本、查看Nginx管理用户、设置网页缓存、配置日志切割、配置Nginx日志切割、设置超时时间

4、在​​www.huhu.com​​​网站配置防盗链防止​​www.huyan.com​​​盗​​www.huhu.com​​的连接

一、在Centos01上安装Nginx，设置网站根目录/www使用域名www.huhu.com访问

1、挂载Centos7系统光盘

[root@centos01 ~]# mount /dev/cdrom /mnt/]()

mount: /dev/sr0 写保护，将以只读方式挂载

2、创建nginx管理账户

[root@centos01 ~]# useradd -M -s /sbin/nologin nginx

3、传输nginx1.16.1文件

[root@centos01 ~]# rz

z waiting to receive.**B0100000023be50

4、安装依赖文件

[root@centos01 ~]# yum -y install pcre-devel zlib-devel

5、解压nginx配置文件

[root@centos01 ~]# yum -y install pcre-devel zlib-devel

6、修改源代码程序

[root@centos01 ~]# vim /usr/src/nginx-1.16.1/src/core/nginx.h

13 #define NGINX_VERSION    "7.0"

14 #define NGINX_VER      "IIS/" NGINX_VERSION

22 #define NGINX_VAR      "IIS"

7、修改Nginx数据包请求头部

[root@centos01 ~]# vim/usr/src/nginx-1.16.1/src/http/ngx_http_header_filter_module.c

49 static u_char ngx_http_server_string[] = "Server: IIS" CRLF;li

8、配置Nginx

[root@centos01 ~]# cd /usr/src/nginx-1.16.1/

[root@centos01 nginx-1.16.1]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_stub_status_module

9、编译安装Nginx

[root@centos01 nginx-1.16.1]# make && make install

10、优化命令

[root@centos01 nginx-1.16.1]# ln -s /usr/local/nginx/sbin/* /usr/local/sbin/

[root@centos01 nginx-1.16.1]# cd

[root@centos01 ~]# nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

11、创建网站根目录www 设置网站主页

[root@centos01 ~]# mkdir /www/

[root@centos01 ~]# echo "www.huhu.com" > /www/index.html

二、在Centos03上安装DNS使用域名访问Centos01上使用域名​​www.huhu.com​​​访问，Centos02使用yum安装apache使用域名​​www.huyan.com​​访问

1、01、02、03配置DNS

1）centos01配置DNS，重启网卡服务

[root@centos01 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32

[root@centos01 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32

TYPE=Ethernet

BOOTPROTO=static

NAME=ens32

DEVICE=ens32

ONBOOT=yes

IPADDR=192.168.100.10

NATMACK=255.255.255.0

DNS1=192.168.100.30



[root@centos01 ~]# systemctl restart network

[root@centos01 ~]# cat /etc/resolv.conf 

\# Generated by NetworkManager

nameserver 192.168.100.30

2）centos02配置DNS 重启网卡服务

[root@centos02 ~]# vim /etc/sysconfig/network-scripts/ifcfg-ens32

[root@centos02 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ens32

\# Generated by NetworkManager

nameserver 192.168.100.30

2、挂载centos7系统光盘 安装DNS

[root@centos03 ~]# mount /dev/cdrom /mnt/

mount: /dev/sr0 写保护，将以只读方式挂载

[root@centos03 ~]# ls /mnt/

CentOS_BuildTag  EULA  images   LiveOS   repodata        RPM-GPG-KEY-CentOS-Testing-7

EFI        GPL  isolinux  Packages  RPM-GPG-KEY-CentOS-7  TRANS.TBL

root@centos03 ~]# rpm -ivh /mnt/Packages/bind-9.9.4-50.el7.x86_64.rpm 

[root@centos03 ~]# rpm -ivh /mnt/Packages/bind-chroot-9.9.4-50.el7.x86_64.rpm

3、配置DNS主配置文件

[root@centos03 ~]# echo "" > /etc/named.conf

[root@centos03 ~]# vim /etc/named.conf

options {

    listen-on port 53 { any; };

    directory "/var/named/";

};

zone "huhu.com" IN {

    type master;

    file "/var/named/huhu.com.zone";

};

zone "huyan.com" IN {

    type master;

    file "/var/named/huyan.com.zone";

};

4、配置DNS区域配置文件 第一台服务器

[root@centos03 ~]# vim /var/named/huhu.com.zone

$TTL       86400

@        SOA       huhu.com.    root.huhu.com. (

        2023021015

        1H

        15M

        1W

        1D

)

@        NS        centos03.huhu.com.

centos03     A        192.168.100.30

www       A        192.168.100.10

[root@centos03 ~]# named-checkzone huhu.com /var/named/huhu.com.zone

zone huhu.com/IN: loaded serial 2023021015

OK

5、配置第二台DNS区域配置文件

[root@centos03 ~]# vim /var/named/huyan.com.zone

$TTL       86400
