如何同步时间？

stccxyjt422

用VMware装的redhat AS5做oracle10g RAC,如何以其中一节点作为时间服务端同步双机的时间？如何修改/etc/ntp.conf（按网上找的改的文件有点乱了）？是需要修改服务端的还是都要修改？在linux客户端上执行ntpdate ntp_server_ip这命令是要把哪里改成服务端的IP地址？我太菜了问题有点多

把ntp_server_ip改成服务端的IP

看我博客里面的一篇讲时间同步的文章

# --- GENERAL CONFIGURATION ---

# Undisciplined Local Clock. This is a fake driver intended for backup
# and when no outside source of synchronized time is available. The
# default stratum is usually 3, but in this case we elect to use stratum
# 0. Since the server line does not have the prefer keyword, this driver
# is never used for synchronization, unless no other other
# synchronization source is available. In case the local host is
# controlled by some external source, such as an external oscillator or
# another protocol, the prefer keyword would cause the local host to
# disregard all other synchronization sources, unless the kernel
# modifications are in use and declare an unsynchronized condition.

server  127.127.1.0      # local clock
fudge   127.127.1.0 stratum 10

你可以在ntp.conf文件里指定ntp server 的IP，然后启动ntpd服务。也可以直接用ntpdate后面接ntp server 来手动同步
