Ubuntu12.04 cannot use the chkconfig Management Service

Today, I did a DRBD experiment in a virtual machine and encountered a problem when I used the chkconfig management service. Root @ node2:/root # chkconfig -- list | grepdrbddrbd is doing a DRBD experiment in the virtual machine today. When using chkconfig to manage the service, a problem occurs.

 
 

  
  
root@node2:/root# chkconfig --list | grep drbd 
  
  
drbd                      0:off  1:off  2:off  3:off  4:off  5:off  6:off 
  
  
root@node2:/root# chkconfig drbd on 
  
  
/sbin/insserv: No such file or directory 
 
 

This is a BUG in Ubuntu 12.04. You can solve it using the following methods:

 
 

  
  
root@node2:/root# whereis insserv 
  
  
insserv: /etc/insserv /etc/insserv.conf /usr/lib/insserv /usr/share/insserv /usr/share/man/man8/insserv.8.gz 
 
 

Read the directories found above one by one and find the files in/usr/lib /.

 
 

  
  
root@node2:/root# ls -l /usr/lib/insserv/ 
  
  
total 56 
  
  
-rwxr-xr-x 1 root root 56368 Apr  9 19:07 insserv 
 
 

Then I made a connection.

 
 

  
  
root@node2:/root# ln -s /usr/lib/insserv /sbin/insserv 
  
  
root@node2:/root# chkconfig drbd on 
  
  
/sbin/insserv: Permission denied 
 
 

From the above we can see that a permission is not allowed, and it is very depressing.

 
 

  
  
root@node2:/root# ls -l /sbin/insserv
  
  
lrwxrwxrwx 1 root root 16 Jun 21 04:27 /sbin/insserv -> /usr/lib/insserv 
  
  
root@node2:/root# ls -l /usr/lib/insserv 
  
  
total 56 
  
  
-rwxr-xr-x 1 root root 56368 Apr  9 19:07 insserv 
 
 

We can see from the above that it is depressing to have permissions,Finally, we found that/usr/lib/insserv is a directory. 

 
 

  
  
root@node2:~# cd /usr/lib/insserv/ 
  
  
root@node2:/usr/lib/insserv# pwd 
  
  
/usr/lib/insserv 
  
  
root@node2:/usr/lib/insserv# ls 
  
  
insserv 
 
 

Then we can solve the problem.

 
 

  
  
root@node2:/usr/lib/insserv# rm -rf /sbin/insserv 
  
  
root@node2:/usr/lib/insserv# ln -s /usr/lib/insserv/insserv /sbin/insserv 
  
  
root@node2:/usr/lib/insserv# chkconfig drbd on 
  
  
The script you are attempting to invoke has been converted to an Upstart 
  
  
job, but lsb-header is not supported for Upstart jobs. 
  
  
insserv: warning: script 'friendly-recovery' missing LSB tags and overrides 
  
  
insserv: Default-Start undefined, assuming empty start runlevel(s) for script `friendly-recovery' 
  
  
insserv: Default-Stop  undefined, assuming empty stop  runlevel(s) for script `friendly-recovery' 
 
 

I reported a bunch of other errors. Check whether the service is OK.

 
 

  
  
root@node2:/usr/lib/insserv# chkconfig --list | grep drbd 
  
  
drbd                      0:off  1:off  2:on   3:on   4:on   5:on   6:off 
  
  
root@node2:/usr/lib/insserv#  
 
 

OK. Now the service is ready. Ubuntu still has bugs. I used to play RedHat and didn't find similar problems.
