Packstack Installation errors

Installation errors

Installation issues

Execution of '/usr/bin/yum -d 0 -e 0 -y install openstack-nova-conductor' returned 1

When installing RDO packages on top of an existing Folsom OpenStack install, you will have several issues, starting with this one.

If you remove the old *openstack* packages and re-run packstack, you will hit a different issue:

PackStackError: Error during puppet run : notice: /Stage[main]/Cinder::Api/Exec[cinder-manage db_sync]/returns: OperationalError: (OperationalError) (1005, "Can't create table 'cinder.volume_glance_metadata' (errno: 150)")

This issue is caused by old databases still existing from a previous install, causing foreign key constraints to fail when tables are recreated.

The simplest solution, if the host is to be dedicated as an OpenStack Compute or Control node, is to take off and nuke the entire site from orbit (in a manner of speaking). This is not advisable if you are using the host for anything except OpenStack, as it will delete all MySQL databases and remove the packages.

Error creating database

When running packstack, I get an error

Applying 10.46.40.170_mysql.pp Applying 10.46.40.170_qpid.pp [ ERROR ] ERROR : Error during puppet run : err: /Stage[main]/Mysql::Config/Exec[set_mysql_rootpw]/returns: change from notrun to 0 failed: mysqladmin -u root password '6dddb52284a84466' returned 1 instead of one of [0] at /var/tmp/packstack/258f358951de4934825c6f48c299e96a/modules/mysql/manifests/config.pp:106 Please check log file /var/tmp/packstack/20130621-082004-3ml2C4/openstack-setup.log for more information

You are trying to install openstack when there is an existing MySQL database installed. As a result, the root password generated by packstack will not match the pre-existing password.

There are a number of possible solutions:

1. Change the root password to the password featured in the error message above and rerun packstack - this will keep existing databases. It is not recommended to share the MySQL database used by Nova as a database server for other applications.

2. Wipe the pre-existing databases with `rm -rf /var/lib/mysql` and rerun packstack

3. Run the uninstall script to reset the host before re-running the quick start
