二.搭建时间同步服务器
1>.ntpd服务端安装ntp服务
[root@manage110.yinzhengjie.org.cn ~]# yum -y install ntp Loaded plugins: fastestmirror base | 3.6 kB 00:00:00 extras | 2.9 kB 00:00:00 updates | 2.9 kB 00:00:00 Loading mirror speeds from cached hostfile * base: mirror.bit.edu.cn * extras: mirror.bit.edu.cn * updates: mirror.bit.edu.cn Resolving Dependencies --> Running transaction check ---> Package ntp.x86_64 0:4.2.6p5-29.el7.centos will be installed --> Processing Dependency: libopts.so.25()(64bit) for package: ntp-4.2.6p5-29.el7.centos.x86_64 --> Running transaction check ---> Package autogen-libopts.x86_64 0:5.18-5.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ============================================================================================================================================================================================================================================================================== Package Arch Version Repository Size ============================================================================================================================================================================================================================================================================== Installing: ntp x86_64 4.2.6p5-29.el7.centos base 548 k Installing for dependencies: autogen-libopts x86_64 5.18-5.el7 base 66 k Transaction Summary ============================================================================================================================================================================================================================================================================== Install 1 Package (+1 Dependent package) Total download size: 614 k Installed size: 1.5 M Downloading packages: (1/2): autogen-libopts-5.18-5.el7.x86_64.rpm | 66 kB 00:00:00 (2/2): ntp-4.2.6p5-29.el7.centos.x86_64.rpm | 548 kB 00:00:00 ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ Total 1.4 MB/s | 614 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction Installing : autogen-libopts-5.18-5.el7.x86_64 1/2 Installing : ntp-4.2.6p5-29.el7.centos.x86_64 2/2 Verifying : ntp-4.2.6p5-29.el7.centos.x86_64 1/2 Verifying : autogen-libopts-5.18-5.el7.x86_64 2/2 Installed: ntp.x86_64 0:4.2.6p5-29.el7.centos Dependency Installed: autogen-libopts.x86_64 0:5.18-5.el7 Complete!

2>.修改ntpd服务端的配置文件
[root@manage110.yinzhengjie.org.cn ~]# egrep -v "^#|^$" /etc/ntp.conf driftfile /var/lib/ntp/drift restrict 192.168.0.0 mask 255.255.248.0 nomodify notrap server 127.127.1.0 fudge 127.127.1.0 stratum 10 includefile /etc/ntp/crypto/pw keys /etc/ntp/keys disable monitor [root@manage110.yinzhengjie.org.cn ~]# [root@manage110.yinzhengjie.org.cn ~]# echo SYNC_HWCLOCK=yes >> /etc/sysconfig/ntpd [root@manage110.yinzhengjie.org.cn ~]#
3>.ntpd服务端启动ntpd服务
[root@manage110.yinzhengjie.org.cn ~]# systemctl start ntpd [root@manage110.yinzhengjie.org.cn ~]# [root@manage110.yinzhengjie.org.cn ~]# systemctl enable ntpd Created symlink from /etc/systemd/system/multi-user.target.wants/ntpd.service to /usr/lib/systemd/system/ntpd.service.

4>.客户端同步ntp服务器端的时间
[root@computing121.yinzhengjie.org.cn ~]# date Sun Jan 12 18:23:59 CST 2020 [root@computing121.yinzhengjie.org.cn ~]# [root@computing121.yinzhengjie.org.cn ~]# ll /var/spool/cron/root -rw------- 1 root root 0 Jan 12 10:42 /var/spool/cron/root [root@computing121.yinzhengjie.org.cn ~]# [root@computing121.yinzhengjie.org.cn ~]# crontab -l [root@computing121.yinzhengjie.org.cn ~]# [root@computing121.yinzhengjie.org.cn ~]# echo "*/10 * * * * /usr/sbin/ntpdate 172.30.7.110 && /usr/sbin/hwclock -w" > /var/spool/cron/root [root@computing121.yinzhengjie.org.cn ~]# [root@computing121.yinzhengjie.org.cn ~]# ll /var/spool/cron/root -rw------- 1 root root 68 Jan 12 10:42 /var/spool/cron/root [root@computing121.yinzhengjie.org.cn ~]# [root@computing121.yinzhengjie.org.cn ~]# crontab -l */10 * * * * /usr/sbin/ntpdate 172.30.7.110 && /usr/sbin/hwclock -w [root@computing121.yinzhengjie.org.cn ~]# [root@computing121.yinzhengjie.org.cn ~]# systemctl restart crond [root@computing121.yinzhengjie.org.cn ~]# [root@computing121.yinzhengjie.org.cn ~]# date Sun Jan 12 10:36:40 CST 2020 [root@computing121.yinzhengjie.org.cn ~]#
三.根据官网的中文文档继续后续安装即可

实际生产环境中一般使用ocata版本较多，遗憾的是，在2020年OpenStack官网对ocata停止yum源的支持，因此得自建yum仓库进行安装。
当你的才华还撑不起你的野心的时候，你就应该静下心来学习。当你的能力还驾驭不了你的目标的时候，你就应该沉下心来历练。问问自己，想要怎样的人生。
