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。
