实现准备

[root@localhost opt]# cd apollo/[root@localhost apollo]# tree.├── logs│  └── access_log└── test.sh
 1.编写shell脚本
  
[root@localhost tmp]# vi /opt/apollo/test.shmypath='/tmp/logs'echo ${mypath}mylog='/opt/apollo/logs/access_log'echo ${mylog}time=`date +%Y%m%d%H%M%S`echo ${time}cp ${mylog} ${mypath}/${time}_access.logecho ${mypath} ${mypath}/${time}_access.log
  
 2.执行test.sh
  
[root@localhost apollo]# ./test.sh
 3.执行ls -la
  
[root@localhost apollo]# ls -latotal 8drwxr-xr-x  2 root root  21 Jan 20 08:00 .drwxr-xr-x. 14 root root 4096 Jan 20 07:07 ..
 4.给文件test.sh赋与执行权限
  
[root@localhost apollo]# chmod +x ./test.sh[root@localhost apollo]# ls -latotal 8drwxr-xr-x  2 root root  21 Jan 20 08:00 .drwxr-xr-x. 14 root root 4096 Jan 20 07:07 ..
  
 5.再次执行,脚本没有报错
  
[root@localhost apollo]# ./test.sh/tmp/logs/opt/apollo/logs/access_log20190120080932/tmp/logs /tmp/logs/20190120080932_access.log
  
 6.编辑定时任务
  
[root@localhost logs]# crontab -eno crontab for root - using an empty onecrontab: installing new crontab
  
 7.查看定时任务
  
* * * * * sh /opt/apollo/test.sh
  
 8.重启crond
  
[root@localhost logs]# service crond reloadRedirecting to /bin/systemctl reload crond.serviceYou have new mail in /var/spool/mail/root
  
 9.编写文件access_log
  
/opt/apollo/logs/access_log[root@localhost logs]# vi /opt/apollo/logs/access_logmmmmmmmmmmmmmmmmmmmmm
  
 10.过1分钟,再去查备份存放目录
  
[root@localhost logs]# cat 20190120083101_access.logdjddjsjsjsjjsjsjsjmmmmmmmmmmmmmmmmmmmmm
  
 11.到此为止,定时备份任务完成.
 
 恭喜你,学会备份了！
 
 12.删除定时任务
  
[root@localhost logs]# crontab -rYou have new mail in /var/spool/mail/root
  
 13.查看定时任务
  
[root@localhost logs]# crontab -lno crontab for root
