前言:
时间服务器部署,这样可以防止网络带来的阻塞和延迟导致服务器的时间不一致,时间的不一致容易导致各种错误。假如监控时间报错了,你老大会怎么想
部署:
1.安装ntp
yum -y install ntp[root@nfs01 ~]# rpm -qa ntpntp-4.2.6p5-10.el6.centos.2.x86_64
2.配置文件
[root@m01 ~]# grep -Ev "#|^$" /etc/ntp.conf driftfile /var/lib/ntp/driftrestrict default nomodifyrestrict 127.0.0.1 restrict -6 ::1server ntp1.aliyun.comserver time.nist.govincludefile /etc/ntp/crypto/pwkeys /etc/ntp/keys
步骤,此处略low,可以使用直推推送配置文件的方法
sed -i 's#server 3.centos.pool.ntp.org iburst##g' /etc/ntp.confsed -i 's#server 2.centos.pool.ntp.org iburst##g' /etc/ntp.confsed -i 's#server 1.centos.pool.ntp.org iburst##g' /etc/ntp.confsed -i 's#server 0.centos.pool.ntp.org iburst##g' /etc/ntp.confsed -i 's#restrict default kod nomodify notrap nopeer noquery##g'sed -i 's#restrict -6 default kod nomodify notrap nopeer noquery##g'echo -e "server ntp1.aliyun.com\nserver time.nist.gov\nrestrict default nomodify" >> /etc/ntp.conf
3.启动并查看
/etc/init.d/ntpd startntpq -p
