關於解決漏洞的問題我就不詳說了，主要就是升級版本。這里我們就直接簡單記錄下步驟：
1、升級 使用root用戶登錄系統進入到/home/guankong ,上傳ntp-4.2.8p9-1.el6.x86_64.rpm到該目錄下 2.安裝依賴包 yum install gcc gcc-c++ openssl-devel libstdc++* libcap* 3.備份舊版本的配置文件 cp -ar /etc/ntp /etc/ntp.bak cp /etc/ntp.conf /etc/ntp.conf.bak cp /etc/init.d/ntpd /etc/init.d/ntpd.bak cp /etc/sysconfig/ntpd /etc/sysconfig/ntpd.bak cp /etc/sysconfig/ntpdate /etc/sysconfig/ntpdate.bak 4.卸載舊的NTPD yum erase ntp ntpdate 5.創建/var/lib/ntp目錄 install -v -m710 -o ntp -g ntp -d /var/lib/ntp //可能存在目錄會報錯 6.安裝rpm包 rpm -i ntp-4.2.8p9-1.el6.x86_64.rpm 7.還原配置文件 cp /etc/init.d/ntpd.bak /etc/init.d/ntpd cp /etc/sysconfig/ntpd.bak /etc/sysconfig/ntpd cp /etc/sysconfig/ntpdate.bak /etc/sysconfig/ntpdate mv /etc/ntp.bak /etc/ntp cp /etc/ntp.conf.bak /etc/ntp.conf
shell腳本命令一鍵執行：
#!/bin/sh chmod 755 -R . install_log=install.log ##ntp upgrade echo "#######1:ntp upgrade ..." 2>&1 | tee -a $install_log \cp -ar /etc/ntp /etc/ntp.bak \cp /etc/ntp.conf /etc/ntp.conf.bak \cp /etc/init.d/ntpd /etc/init.d/ntpd.bak \cp /etc/sysconfig/ntpd /etc/sysconfig/ntpd.bak \cp /etc/sysconfig/ntpdate /etc/sysconfig/ntpdate.bak yum -y erase ntp ntpdate 2>&1 | tee -a $install_log rpm -i ntp-4.2.8p9-1.el6.x86_64.rpm 2>&1 | tee -a $install_log \cp /etc/init.d/ntpd.bak /etc/init.d/ntpd \cp /etc/sysconfig/ntpd.bak /etc/sysconfig/ntpd \cp /etc/sysconfig/ntpdate.bak /etc/sysconfig/ntpdate rm /etc/ntp -rf mv /etc/ntp.bak /etc/ntp \cp /etc/ntp.conf.bak /etc/ntp.conf echo "ntp upgrade end !" 2>&1 | tee -a $install_log
需要文件：ntp-4.2.8p9-1.el6.x86_64.rpm,自行百度下載
