10g Grid and Cluster on single node

Hi,

I wanna install a single node Grid (for testing) on Whitebox Linux.

1. I prepared one registry raw partition and one voting disk partition.
2. I configure the public and private address and ssh two addresses well.
3. No database or instance in that node. Just prepare 2 ASM disks.
4. I run ./runInstaller in crs dir.
5. I answer the questions and start to install.
6. When I want to run root.sh by root, it hangs on CSS daemon starts.
7. I ignore it and continue to install crs, but fails.

The question is: what's wrong?

The next question is: is it correct to install CRS before installing the database?
