Shanker Balan created CLOUDSTACK-1623:
-----------------------------------------
Summary: MySQL Database connection can fail to "localhost" on a V6
enabled host
Key: CLOUDSTACK-1623
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1623
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Doc
Environment: CentOS / RHEL MySQL
Reporter: Shanker Balan
Priority: Trivial
The below snippet can fail on a host with a IPv6 loopback entry in the hosts
file and MySQL is not setup to listen on the loopback interface.
cloud-setup-databases cloud:<dbpassword>@localhost \
--deploy-as=root:<password> \
-e <encryption_type> \
-m <management_server_key> \
-k <database_key>
The documentation could be updated to mention:
1) Ensure that MySQL is running on the IPv6 loopback interface ::1
2) OR, remove the "localhost" entry which points to "::1" from the hosts file
[root@db01 ~]# telnet ::1 mysql
Trying ::1...
telnet: connect to address ::1: Connection refused
[root@db01 ~]# telnet 127.0.0.1 mysql
Trying 127.0.0.1...
