CentOS7: missing wget in installation chroot blocks postinstallationscripts.

[ronan-kerviche]

wget is not present in the installation chroot for CentOS7 and ends up blocking the post-installation scripts in /opt/xcat/share/xcat/install/scripts/post.xcat. Alternatives such as curl are available.

@ronan-kerviche , what's your osimage definition?

[ronan-kerviche]

Right after copycds :

$ lsdef -t osimage centos7.3-x86_64-install-compute
Object name: centos7.3-x86_64-install-compute

wget is included in /opt/xcat/share/xcat/install/centos/compute.centos7.pkglist, if you can access the installed compute node, would you please take a look at whether wget is installed?

[root@c910f03c05k21 ~]# cat /opt/xcat/share/xcat/install/centos/compute.centos7.pkglist
#Please make sure there is a space between @ and group name
wget

rsync

wget is indeed installed but is outside of the chroot environment in which post.xcat is running. I verified that 'which wget' and 'find / -name wget' both fail there (PATH contains '/bin' and '/usr/bin').

[immarvin]

what is the full path of wget on the installed node?
by default, the post.xcat included in %post is run in the chroot environment, which is the installed root file system. So you mentioned you run 'which wget' or 'find / -name wget' , did you mean you run the commands inside the installer?

[ronan-kerviche]

From the installer command line, wget is in /usr/bin which is outside the chroot in which post.xcat is running. To verify this I added 'which' and 'find' to the post.xcat template on the management node and pushed the installation to a compute node. The information is then visible in xcat.log.

[robin2008]

try to recreate it if possible, if not we can close it.

[immarvin]

cannot recreate, close this first. please reopen it if it is still there
