+ | </ | ||
+ | |||
+ | Then build the node up: | ||
+ | |||
+ | * use yum to install the openlava 2.2.1 RPM (pulls in tcl) | ||
+ | * copy the openlava config files into the centos-6 are | ||
+ | * use yum to install postfix | ||
+ | * add links in rc3.d and rc5.d | ||
+ | * remove sendmail links | ||
+ | * yum install perl | ||
+ | * yum install munge | ||
+ | * build RPMs from tar ball | ||
+ | * rebuild the VNFS and reboot | ||
