解决ubuntu的chkconfig[/sbin/insserv 无法找到路径问题]

http://www.cnblogs.com/lost-1987/archive/2012/10/17/2727285.html

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。
