时间定时同步

修改系统时间由三种方法：

一、修改时区

  1. cp /etc/localtime /etc/localtime.bak
  2. ln -svf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
  4. #修改为中国的东八区
  5. vim /etc/sysconfig/clock
  6. ZONE="Asia/Shanghai"
  7. UTC=false
  8. ARC=false
  10. #与时间服务器同步
  11. ntpdate ntp服务器的ip

二、配置新的时间

  1. #日期设定
  2. date -s 2013/09/26
  3. #时间设定
  4. date -s "11:47:06"
  5. date -s "12:00:00 2013-12-06"
  6. ....
  7. #date是显示的系统的OS时间
  8. #clock是显示的BIOS的时间
  10. #查看硬件的时间
  11. hwclock [-rw]
  12. -r    查看现有BIOS时间。默认为-r参数
  13. -w    将现在的linux系统时间写入BIOS中
  14. -s    （systohc）将硬件时间调整为和目前的系统时间一半

三、时间自动同步

  1. #1.开机自动网络校时
  2. cat /etc/rc.d/rc.local
  3. /usr/sbin/ntpdate -u    192.168.10.80
  5. #2.设置定时计划任务
  6. #yum install -y ntpdate （yum安装时间同步命令）
  7. crontab -e
  8. #加入内容
  9. */5    *    * * * root    ntpdate    192.168.10.80 #每隔五分钟与时间服务器同步一次时间

日志定时清理

清理日志脚本

  1. #!/bin/bash
  2. date >>/home/wdhis/logs/catalina.out
  3. echo "del file start....." >> /home/wdhis/logs/catalina.out
  4. find /home/wdhis/logs/*/*.log -mtime +14 -name "*.log"  -exec rm -rf {} \; >> /home/wdhis/logs/catalina.out
  5. find /home/wdhis/Server/dubbo-consumer/dubbo-emis-tomcat/logs/* -mtime +14 -name "*"  -exec rm -rf {} \; >> /home/wdhis/logs/catalina.out
  6. find /home/wdhis/Server/dubbo-consumer/dubbo-mmis-tomcat/logs/* -mtime +14 -name "*"  -exec rm -rf {} \; >> /home/wdhis/logs/catalina.out
  7. find /home/wdhis/Server/dubbo-consumer/dubbo-outpat-tomcat/logs/* -mtime +14 -name "*"  -exec rm -rf {} \; >> /home/wdhis/logs/catalina.out
  8. find /home/wdhis/Server/dubbo-consumer/dubbo-core-tomcat/logs/* -mtime +14 -name "*"  -exec rm -rf {} \; >> /home/wdhis/logs/catalina.out
  9. find /home/wdhis/Server/dubbo-consumer/dubbo-plugs-tomcat/logs/* -mtime +14 -name "*"  -exec rm -rf {} \; >> /home/wdhis/logs/catalina.out
  10. echo " " > /home/wdhis/Server/dubbo-consumer/wdhis-emis-svr/logs/catalina.out
  11. echo " " > /home/wdhis/Server/dubbo-consumer/wdhis-mmis-svr/logs/catalina.out
  12. echo " " > /home/wdhis/Server/dubbo-consumer/wdhis-outpat-svr/logs/catalina.out
  13. echo " " > /home/wdhis/Server/dubbo-consumer/wdhis-core-svr/logs/catalina.out
  14. echo " " > /home/wdhis/Server/dubbo-consumer/wdhis-plugs-svr/logs/catalina.out
  15. echo "del file end" >> /home/wdhis/logs/catalina.out
  16. echo "del file provide nohup" >> /home/wdhis/logs/catalina.out
  17. echo " " > /home/wdhis/Server/dubbo-provider/wdhis-medicare-svr/nohup.out
  18. echo " " > /home/wdhis/Server/dubbo-provider/wdhis-outplugs-svr/nohup.out
  19. echo " " > /home/wdhis/Server/dubbo-provider/wdhis-payment-svr/nohup.out
  20. echo " " > /home/wdhis/Server/dubbo-provider/wdhis-report-svr/nohup.out
  21. echo "del file end nohup" >> /home/wdhis/logs/catalina.out
  22. date >> /home/wdhis/logs/catalina.out
  24. #设置脚本执行权限
  25. chmod +x delete-logs.sh

将脚本加入定时任务

  1. [root@admin wdhis]# crontab -e
  2. crontab: installing new crontab
  3. [root@admin wdhis]# crontab -l
  4. #定时清理云HIS日志，在每隔十五天的0点
  5. * 0 */15 * * wdhis /home/wdhis/logs/delete_log.sh
