Does this work fine in AliOS?
Please add some result of that in the comment of this pr, @HusterWan
Thanks a lot.

Does this work fine in AliOS?

The answer is Yes, the reason why the test case failed is the ps -ef print title UID PID PPID C STIME TTY TIME CMD has different spaces number between each item on centos 7 and alios, so i trim all the space, and just compare the string UIDPIDPPID
