1、卸载阿里云盾（安骑士）
wget http://update.aegis.aliyun.com/download/uninstall.sh
chmod +x uninstall.sh
./uninstall.sh
wget http://update.aegis.aliyun.com/download/quartz_uninstall.sh
chmod +x quartz_uninstall.sh
./quartz_uninstall.sh
删除残留
pkill aliyun-service
rm -fr /etc/init.d/agentwatch /usr/sbin/aliyun-service
rm -rf /usr/local/aegis*卸载后可以查看自己云服务器进程，已经没有了AliYunDun、aliyun-service、AliYunDunUpdate三项。
2、屏蔽云盾IP。执行下面命令通过“iptables”防火墙来屏蔽云盾IP。
iptables -I INPUT -s 140.205.201.0/28 -j DROP
iptables -I INPUT -s 140.205.201.16/29 -j DROP
