saltstack的状态文件
最近发现很多服务器上没有配置ntp服务器指向，简单写个计划任务，然后通过状态文件下发思路：
a）准备好需要下发的文件
b）编辑sls文件
c）修改top.sls，添加信息进去
# cat /var/spool/cron/root
*/5 * * * * /usr/sbin/ntpdate -u 202.120.2.101>/dev/null 2>&1
# cd /etc/salt/states/
# ls
initprodtop.sls
# cd init/
# ls
fileslimit.slspkg.sls
# cp limit.sls ntp-crontab.sls
# ls
fileslimit.slsntp-crontab.slspkg.sls
# cd files/
# cp /var/spool/cron/root .
# pwd
/etc/salt/states/init/files
# cat root
*/5 * * * * /usr/sbin/ntpdate -u 202.120.2.101>/dev/null 2>&1
# mv root ntp-crontab.conf
# cat ntp-crontab.conf
*/5 * * * * /usr/sbin/ntpdate -u 202.120.2.101>/dev/null 2>&1
# cd ..
# ls
fileslimit.slsntp-crontab.slspkg.sls
# cat /etc/salt/states/init/ntp-crontab.sls
ntp-crontab-config:
file.managed:
- name: /var/spool/cron/root
- source: salt://init/files/ntp-crontab.conf
- user: root
- group: root
- mode: 644
计划任务更新执行结果：

检查结果：
# cd /var/spool/cron/
# ls
root
# cat root
*/5 * * * * /usr/sbin/ntpdate -u 202.120.2.101>/dev/null 2>&1
# cat /var/spool/cron/root
*/5 * * * * /usr/sbin/ntpdate -u 202.120.2.101>/dev/null 2>&1
通过对比会发现，与master的下发文件一致
