Ubuntu 12.04不能使用chkconfig管理服務

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 

這是Ubuntu 12.04的一個BUG，使用以下方法可以解決

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

把上面找到的目錄，一個一個的看一遍，發現文件在/usr/lib/裡面

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

然後我就做了個連接過去

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

從上面看出，報了一個權限不允許，很郁悶

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 

從上面看出，有權限的啊，好郁悶，最後發現 /usr/lib/insserv竟然是一個目錄

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

然後就好解決了

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' 

報了一堆的其它錯誤，先不管吧，看看服務OK沒

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,現在看到服務已經搞定了。Ubuntu還是有Bug的，呵呵，好像還挺多。以前總是玩RedHat，沒發現類似的問題。
