centos 7 NTP同步设置

以前单位都是ubuntu，最近改到了centos，记录下ntp配置

1.安装ntp

yum install ntp ntpdate

2.启动ntp

systemctl start ntpd

systemctl enable ntpd

3.配置内部地址

vim  /etc/ntp.conf

注释

#server 0.centos.pool.ntp.org iburst
#server 1.centos.pool.ntp.org iburst
#server 2.centos.pool.ntp.org iburst
#server 3.centos.pool.ntp.org iburst

#局域网设置：server 127.0.0.1 iburst
server 10.2.2.102 iburst

# 配置允许上游时间服务器主动修改本机的时间
restrict 10.2.2.102 nomodify notrap noquery

4.重启NTP

systemctl restart ntpd

5.查看检查状态

ntpstat
