环境
源主机：192.168.10.158
系统：centos 7.4
域名：www.wuxier.cn
盗链主机：192.168.10.191（使用Nginx+Tomcat实现负载均衡、动静分离的实验主机，点我进行复盘）
系统：centos 7.4
域名：www.ajie.com 和 www.taobao.com

配置环境变量

[[email protected] bin]# vi /etc/profile  #新增下面三行
export JAVA_HOME=/usr/local/jdk1.8.0_181
export CLASSPATH=.:$JAVA_HOME/lib
export PATH=$PATH:$JAVA_HOME/bin

[[email protected] bin]# source /etc/profile

关闭selinux

[[email protected] bin]# getenforce

防盗链结果验证
当访问taobao1的时候，因为taobao1之前是使用了 www.wuxier.cn/wuxier.jgp 图片，所以会返回盗链的图片，如下图

当访问taobao2的时候，如下图

当访问 www.wuxier.cn 的时候，如下图（白名单）

当访问 www.ajie.com 的时候，如下图（白名单）

当从配置文件wuxier.conf中将*ajie.com和ajie.com从白名单中删除后，再进行访问

[[email protected] conf.d]# vim /etc/nginx/conf.d/wuxier.conf 
server {
    listen       80;
    server_name  www.wuxier.cn;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

#    location ~ .*.(gif|jpg|png|jpeg|bmp|ico|css)$ {
#        root   /usr/share/nginx/html;
#        autoindex on;
#        expires 2d;
#    }

    location ~*.(jpg|png|gif|jpeg)$ {
           root  /usr/share/nginx/html;
           valid_referers none blocked  *.wuxier.cn  wuxier.cn;  #将*.ajie.com和ajie.com删除
           if ($invalid_referer) {
