ubuntu 设置crontab日志

1.编辑/etc/rsyslog.d/50-default.conf,去掉 #cron前注释

sudo vim /etc/rsyslog.d/50-default.conf

2.重启rsyslog和cron服务

sudo systemctl restart rsyslog
sudo systemctl restart cron

3.每5秒查看一次cron.log日志

watch tail -n 50 /var/log/cron.log

4. 一键设置脚本

sudo sed -i 's/^#cron/cron/' /etc/rsyslog.d/50-default.conf
sudo systemctl restart rsyslog
sudo systemctl restart cron
watch tail -n 50 /var/log/cron.log
