ConfigurationFrom 2013/10 OpenStack introduces a new configuration method that uses the configuration file local.conf. From the official website, this file should exist in the Devstack directory and found in the Samples directory. The Create local.conf contains the following content:

#Admin密码 //Pre-set password so that no password is required when running stack.sh //Ibid . //Ibid.
Service_token=a682f596-76f3-11e3-b3b2-e716f9080d50

Other Available configuration items:
Installation path:
  Default: Dest=/opt/stack
  Example:dest=/opt/mystack

 Default is console output:screen_logdir= ""
 Example:   screen_logdir= $DEST/logs/screen #输出到文件, each screen output is a file named with a timestamp

4. Run the following command as a non-root userCD devstack./stack.sh Note: 1. You cannot run the command using the root user, you can use the/devstack/tools/create-stack-user.sh command to create a user, such as Stack2. Ensure that the user under Sudo can run without password, or there will be a permissions issue during script execution

Method: Modify/etc/sudoers, add stack after line root all =(all:all) All all= (All) and then save the file
