用过阿里云的ECS的都知道，ECS会自动安装阿里云盾，其实是个没什么用的东西，很多人购买了ECS之后会立马关闭甚至卸载它。

        以下是centos 7 的关闭、卸载的方法。

        1、centos 7 关闭阿里云盾

        xshell进入centos命令行，

         # chkconfig --list     // 看一下aliyundun是否在开机自启的选项里

        

        图中aegis就是aliyunudn的服务，停掉它 

        # chkconfig --del aegis  // 删除服务

        # service aegis stop  //停止服务

        2、卸载

        工具卸载：

        # wget http://update.aegis.aliyun.com/download/uninstall.sh
        # sh uninstall.sh
        # wget http://update.aegis.aliyun.com/download/quartz_uninstall.sh

        # sh quartz_uninstall.sh

        删除残余：

        # pkill aliyun-service
        # rm -fr /etc/init.d/agentwatch /usr/sbin/aliyun-service

        # rm -rf /usr/local/aegis*

        屏蔽阿里ip：

        安装了firewalld的执行以下命令：        

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.201.0/28' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.201.16/29' reject"

        #  firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.201.32/28 ' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.192/29' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.200/30' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.184/29' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.183/32' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.206/32' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.205/32' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.195/32' reject"

        # firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='140.205.225.204/32' reject"

        # firewall-cmd --reload

       安装了iptables的执行以下命令

        # iptables -I INPUT -s 140.205.201.0/28 -j DROP
        # iptables -I INPUT -s 140.205.201.16/29 -j DROP
        # iptables -I INPUT -s 140.205.201.32/28 -j DROP
        # iptables -I INPUT -s 140.205.225.192/29 -j DROP
        # iptables -I INPUT -s 140.205.225.200/30 -j DROP
        # iptables -I INPUT -s 140.205.225.184/29 -j DROP
        # iptables -I INPUT -s 140.205.225.183/32 -j DROP
        # iptables -I INPUT -s 140.205.225.206/32 -j DROP
        # iptables -I INPUT -s 140.205.225.205/32 -j DROP
        # iptables -I INPUT -s 140.205.225.195/32 -j DROP
        # iptables -I INPUT -s 140.205.225.204/32 -j DROP

        # systemctl restart iptables.service
