innodb-read-only=0

in my.cnf but no luck any suggestions thanks

Answer 1

You have this in your config:

innodb_force_recovery=4

http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html says:

As of 5.6.6, an innodb_force_recovery setting of 4 or greater places InnoDB in read-only mode.

That option is something you'd do only while trying to extract data from a corrupted tablespace. You should remove that option from you my.cnf and restart.
