之前写过一个定时关机的crontab，后来关掉之后发现还是每天定时关机
查看crontab状态
1 [root@puppetclient var]# service crond status 2 crond dead but pid file exists
提示报错： crond dead but pid file exists
解决过程
ps -ef | grep crond 以及把进程杀死 查看还是有该报错
尝试把进程文件删除掉
1 [root@puppetclient var]# find -name cron* 2 ./spool/anacron/cron.daily 3 ./spool/anacron/cron.weekly 4 ./spool/anacron/cron.monthly 5 ./spool/cron 6 ./lock/subsys/crond 7 ./run/cron.reboot 8 ./run/crond.pid 9 10 [root@puppetclient run]# rm -rf crond.pid 11 [root@puppetclient run]# service crond status 12 crond dead but subsys locked
查看还是有该报错
然后，尝试重启crontab
1 [root@puppetclient run]# service crond restart 2 Starting crond: [ OK ] 3 [root@puppetclient run]# service crond status 4 crond (pid 6131) is running... 5 [root@puppetclient run]# service crond stop 6 Stopping crond: [ OK ] 7 [root@puppetclient run]# service crond status 8 crond is stopped
解决方法：
建议先尝试重启下查看是否还有该报错
如果还有的话 需要把进程文件删除掉
