ubuntu 定时任务

编辑crontab的配置：

# /etc/crontab: system-wide crontab
# Unlike any other crontab you don't have to run the `crontab'
# command to install the new version when you edit this file
# and files in /etc/cron.d. These files also have username fields,
# that none of the other crontabs do.

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

# Example of job definition:
# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |

配置cron日志

1. 修改rsyslog

   vim /etc/rsyslog.d/50-default.conf
   cron.*       /var/log/cron.log [[将cron前面的注释符去掉]] 
   

2. 重启rsyslog，cron

   sudo service rsyslog restart
   
   sudo service cron restart
   
   # 查看crontab日志
   tail -n 10 /var/log/cron.log
