Install new mysql instance on unix

[Jitender Singh]

Hi, I am using Redhart unix and want to run another instance of mysql. I already have a single instance of Mysql version 5.0 running on the same box and i want to install a new mysql version 5.5 on same machine. I did do all the basic like creating a new mysql user, directory structure, i have also downloaded binary of that mysql version and did untar in the new folder eg (/var/lib/mysql55). i have created my.cnf file under /var/lib/mysql55 but when i run mysql_install_db --user=mysql55, i get below error.

121221 7:50:19 [Note] Plugin 'InnoDB' is disabled.
121221 7:50:19 [Note] Plugin 'FEDERATED' is disabled.
121221 7:50:19 [ERROR] /var/rotate/mysql/mysql55//bin/mysqld: unknown option '--skip-bdb'
121221 7:50:19 [ERROR] Aborting

121221 7:50:19 [Note] /var/rotate/mysql/mysql55//bin/mysqld: Shutdown complete

i also made changed in mysql_install_db and removed option --skip-bdb but still when i run same command to install, i get the same result.

I would really appreciate on any suggestion on this.
