同步集群单板时间的shell脚本

0.readme.txt

完成功能：以当前服务器时间为标准时间，同步时间给ip.txt文件中列出的服务器
需要同步的IP：添加到ip.txt（注意：不能把linux本机IP放到里面）
执行前配置：ntp.conf中 server 122.138.73.8（修改为linux本机IP）
执行用户：root
执行路径：/root/bin(建议放在该路径下执行)
执行命令：./synctime.sh

ps:为了执行同步时间的正确性，延长远程执行时间为1分钟，主要用于判断时间是否真正同步成功
另外借用了颜色区分显示执行结果，让执行者更快看到执行情况

"Password:" { send "PASSWD\r";exp_continue }
"#" {send "\r"}

## Radio and modem clocks by convention have addresses in the
## form 127.127.t.u, where t is the clock type and u is a unit
## number in the range 0-3.
##
## Most of these clocks require support in the form of a
## serial port or special bus peripheral. The particular
## device is normally specified by adding a soft link
## /dev/device-u to the particular hardware device involved,
## where u correspond to the unit number above.
##
## Generic DCF77 clock on serial port (Conrad DCF77)
## Address: 127.127.8.u
## Serial Port: /dev/refclock-u
##
## (create soft link /dev/refclock-0 to the particular ttyS?)
##
# server 127.127.8.0 mode 5 prefer

##
## Undisciplined Local Clock. This is a fake driver intended for backup
## and when no outside source of synchronized time is available.
##
