When revoking privileges from a user, the GRANT OPTION is always revoked, even if the user doesn't have it. If the user exists, this doesn't give an error, but if the user doesn't exist, it does: mysql> GRANT ALL ON test.* TO 'test'@'localhost'; Query OK, 0 rows affected (0.00 sec) mysql> REVOKE GRANT OPTION ON test.* FROM 'test'@'localhost'; Query OK, 0 rows affected (0.00 sec) mysql> REVOKE GRANT OPTION ON test.* FROM 'test'@'localhost'; Query OK, 0 rows affected (0.00 sec) mysql> REVOKE ALL ON test.* FROM 'test'@'localhost'; Query OK, 0 rows affected (0.00 sec) mysql> REVOKE GRANT OPTION ON test.* FROM 'test'@'localhost'; ERROR 1141 (42000): There is no such grant defined for user 'test' on host 'localhost' Additionally, in MySQL 5.6 this breaks replication because of http://bugs.mysql.com/bug.php?id=68892. Rather than revoking the GRANT OPTION and catching the error, check if the user actually has it and only revoke it when he does.
Ansible
Ansible is a radically simple configuration-management, deployment, task-execution, and multinode orchestration framework.
Read the documentation and more at http://ansibleworks.com/
Many users run straight from the development branch (it's generally fine to do so), but you might also wish to consume a release. You can find instructions on http://ansibleworks.com/docs/gettingstarted.html for a variety of platforms. If you want a tarball of the last release, go to http://ansibleworks.com/releases/ and you can also install with pip (though that will bring in some optional binary dependencies you normally do not need).
Design Principles
- Dead simple setup
- Super fast & parallel by default
- No server or client daemons; use existing SSHd
- No additional software required on client boxes
- Modules can be written in ANY language
- Awesome API for creating very powerful distributed scripts
- Be usable as non-root
- The easiest config management system to use, ever.
