apache防盗链模块mod_auth_token安装配置

下载安装包：

wget http://mod-auth-token.googlecode.com/files/mod_auth_token-1.0.6-beta.tar.gz
tar zxvf mod_auth_token-1.0.6-beta.tar.gz
cd mod_auth_token
rm -f configure 
autoreconf -fi 
automake -f 
./configure --prefix=/usr && make && make install

编辑apache的配置文件httpd.conf
