今天在虚拟机里做DRBD实验，使用chkconfig管理服务的时候，出现了问题。

  

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

这是Ubuntu 12.04的一个BUG，使用以下方法可以解决    


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


把上面找到的目录，一个一个的看一遍，发现文件在/usr/lib/里面     


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


然后我就做了个连接过去   


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


从上面看出，报了一个权限不允许，很郁闷  


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

 
从上面看出，有权限的啊，好郁闷，最后发现 /usr/lib/insserv竟然是一个目录     

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


然后就好解决了     


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'



报了一堆的其它错误，先不管吧，看看服务OK没    

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,现在看到服务已经搞定了。Ubuntu还是有Bug的，呵呵，好像还挺多。以前总是玩RedHat，没发现类似的问题。
