I think your mysql is installed in the rpm package, and it is very likely that some packages are not completely installed.

//Install the rpm package of mysql.

# rpm-IVH MySQL-XXXXXX- 1 1 . i386 . rpm

# rpm-IVH MySQL-server-XXXXXX- 1 1 . i386 . rpm

# rpm-IVH MySQL-devel-XXXXXX- 1 1 . i386 . rpm

Install the RPM dependency package required by MYSQL.

# rpm-IVH perl-CGI-XXXXXX . i386 . rpm

# rpm-IVH perl-DBI-xxxxx . i386 . rpm

# rpm-IVH perl-DBD-MySQL-XXXXXX-3 . i386 . rpm
