i got it fixed by myself by re-do everything. remove existing folders:
devstack , stack. then as following steps to re-do:

1. Download DevStack (i am using root user)
     cd /opt
     git clone https://git.openstack.org/openstack-dev/devstack
     note: if error occurs, its better to remove the existing files and re-download.

2.  Add stack user, even you already created stack user, you can run the command.
     cd /opt/devstack/tools
     ./create-stack-user.sh

3.  Change the ownership to stack.
      cd /opt/
      chown -R stack:stack /opt/devstack

4.  switch to stack user (password is stack)
      su stack

5.  Additional changes, which block me for several days.
     i have to edit /opt/devstack/stackrc file, change the line   GIT_BASE=${GIT_BASE:-git://git.openstack.org} to  GIT_BASE=${GIT_BASE:-https://git.openstack.org}, as the git:// is not available to me. (i am in China)

6. run stack.sh (remember now i am using stack user)
    cd /opt/devstack
    ./stack.sh
    Note: this will take a few hours to complete download. if error occurs, you can re-run ./stack.sh, as it will continue downloading the incomplete files, instead start from scratch.

7. once step 6 completed successfully, you will be able see log, saying
how long stack.sh completed

8. now you can goto browser to login the dashboard.
