这样子的：
Administrator@123-9kcd842e4li ~
$ groupadd -g99 bbs
bash: groupadd: command not found

Administrator@123-9kcd842e4li ~
$ useradd -u9999 bbs
bash: useradd: command not found

怎么办？在检测的时候
2.7 Telnet部分测试运行及配置

$ ipc-daemon2&
$ /home/bbs/bin/shminit

(如果成功会提示 everything is just fine)
$ /home/bbs/bin/bbsd


可是现在是这样的：
Administrator@123-9kcd842e4li ~
$ ipc-daemon2&
[1] 2308

Administrator@123-9kcd842e4li ~
$ /home/bbs/bin/shminit

please run this program as bbs user
don't run this program as root!
oops, shminit failed, please clear all shm and retry
[1]+  Done                    ipc-daemon2

怎么办？～～～～～～～～～～～～～：（
