Do not use 'rhoconnect redis-install' on linuxes. Simply after make command run
$ sudo make install
and you will have redis-server and other binaries in /usr/local.
I advice also copy redis config file there:
$ sudo cp redis.conf /usr/local/etc
After that you can edit this file and tweak it as you like.
You can run redis-server directly
$ redis-server /usr/local/etc/redis.conf
or use rhoconnect wrapper script
$ rhoconnect redis-start
Thank you, Alexander, very appreciated your help.
