mysql upgrade not working

[Paul Singleton]

I am trying to upgrade from 5.1 to 5.5 -- I do a chroot and it works on 5.1 but it is giving me some trouble on 5.5. When I start the server as follows i get:

/opt/mysql/mysql/bin/mysqld --no-defaults --user=mysql

140827 10:57:57 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306
140827 10:57:57 [Note] - '0.0.0.0' resolves to '0.0.0.0';
140827 10:57:57 [Note] Server socket created on IP: '0.0.0.0'.

But when I do the same with the chroot:

/opt/mysql/mysql/bin/mysqld --no-defaults --user=mysql --chroot=/export/home/mysql/ --datadir=/data

140827 11:02:20 [Note] Server hostname (bind-address): '0.0.0.0'; port: 3306
140827 11:02:20 [ERROR] Can't create IP socket: Permission denied
140827 11:02:20 [ERROR] Can't start server: cannot resolve hostname!

I had in my my.cnf to put the socket in /tmp and there is a /tmp dir in my chroot that the mysql user has rw to. I cannot figure out what I need to change. Any help will be appreciated.
