mailboxd cant connect to mysql database, zimbra dead

[stegbth]

hi all,

i am upgraded zimbra 6.0.15 to zimbra 7.1.4p1 running on Ubuntu 10.04 today.
After the upgrade the mailboxd cant connect to the database.

in the mailboxd.log i get:

Caused by: com.mysql.jdbc.exceptions.jdbc4.CommunicationsExce ption: Communications link failure

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
Caused by: java.net.ConnectException: Connection refused

then i checked, the database is running on port 7306.
then i found in localconfig.xml there are some entries missing

<key name="mysql_socket">
<value>${zimbra_db_directory}/mysql.sock</value>
</key>
<key name="mysql_mycnf">
<value>${zimbra_home}/conf/my.cnf</value>
</key>
<key name="mysql_data_directory">
<value>${zimbra_db_directory}/data</value>
</key>
<key name="zimbra_mysql_user">
<value>zimbra</value>
</key>

but zmmailboxd still cant connect to the database.
But trying
mysql -u root -h localhost -p is able to connect to the database.

migrate20100913-Mysql51.pl did also run fine.

any ideas?

Hi,

the mailboxd can connect to MySQL again.

problem was localhost resolved to IPv6 ::1 instead of IPv4 127.0.0.1

thank you
