Nginx图片/文件防盗链配置
发布时间:April 7, 2012 // 分类:Nginx // No Comments
Nginx可根据浏览器请求的Referer防盗链,限制非本站的页面链接请求,更严格的限制可使用防盗链模块nginx-accesskey,可防止迅雷盗链。
编辑Nginx配置文件,在Server段加入以下内容:
location ~* \.(jpg|gif|png)$ { #限制的文件类型
valid_referers none blocked *.www.haiyun.me www.haiyun.me; #定义允许的域名
if ($invalid_referer) { #如果请求非允许
#rewrite ^/ https://www.haiyun.me/error.png; #定向到指定图片
return 403; #返回403
}
}

/usr/local/mysql/bin/mysqld_safe --skip-grant-tables &
3.以空密码方式登录mysql
mysql -u root
4.重置root账号密码
update mysql.user set password=PASSWORD('newpassword') where User='root';

Nginx限制IP请求数防CC攻击
发布时间:April 6, 2012 // 分类:Nginx,网络安全 // No Comments
适用于Nginx服务器,如需通过自带防火墙限制请参考iptables防CC
编辑Nginx配置文件在http段添加:
limit_req_zone $binary_remote_addr zone=req:10m rate=2r/s;
#定义会话存储区,名字为reg,每秒2个请求
server添加:
location /path/ #限制的目录
{
limit_req_zone zone=reg burst=2; #突发最高每秒2个请求数
}
Nginx安全设置上传目录无php执行权限。

编辑Nginx配置文件在fastpass前添加以下内容
location ~* ^/www.haiyun.me/.*\.(php|php5)$ #限制/data/attachment/目录
{
deny all; #拒绝执行php程序
}
重启nginx
service nginx restart
