crontab 状态-关闭-重 启

crond dead but pid file exists 问题解决办法

 

[root@gql_if_pj-znjr_znjr-python_formal_10.991 model]#service crond status
crond dead but pid file exists
[root@gql_if_pj-znjr_znjr-python_formal_10.991 model]#service crond restart
Starting crond: [ OK ]
[root@gql_if_pj-znjr_znjr-python_formal_10.991 model]#service crond status
crond (pid 30193) is running...
 

  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
