Description

Description of problem: With a fresh install of foreman 2.0 on Centos 7 using centos-release-scl, when setting up a freeipa realm, the proxy.log had the following error
[E] Disabling all modules in the group ['realm_freeipa', 'realm'] due to a failure in one of them: Gem loading error: cannot load such file -- xmlrpc

The problem is that foreman-proxy doesn't have the rights on the directory to download the gem and it isn't already present.

Version-Release number of selected component (if applicable): Version 2.0

Steps to reproduce.
These are my build instructions
1. Clean Centos install
2. Install repos

sudo yum -y install epel-release centos-release-scl
sudo yum -y install https://yum.puppet.com/puppet6-release-el-7.noarch.rpm
sudo yum -y install https://yum.theforeman.org/releases/2.0/el7/x86_64/foreman-release.rpm

3. Open firewall

sudo firewall-cmd --permanent --add-service https
sudo firewall-cmd --permanent --add-service http
sudo firewall-cmd --permanent --add-service puppetmaster
sudo firewall-cmd --permanent --add-service dhcp
sudo firewall-cmd --permanent --add-service tftp
sudo firewall-cmd --reload

4. Install base foreman

sudo foreman-installer \
    --foreman-proxy-dhcp=true \
    --foreman-proxy-dhcp-config=/etc/dhcp/dhcpd.conf \
    --foreman-proxy-dhcp-leases=/var/lib/dhcpd/dhcpd.leases \
    --foreman-proxy-dhcp-key-name=omapi-key \
    --foreman-proxy-dhcp-key-secret=$OMAPI_SECRET \
    --foreman-proxy-dhcp-server=foreman.example.com \
    --foreman-proxy-dhcp-interface=ens192 \
    --foreman-proxy-dhcp-gateway=192.168.1.1 \
    --foreman-proxy-dhcp-range="192.168.1.100 192.168.11.199" \
    --foreman-proxy-dhcp-nameservers="192.168.1.11" \
    --foreman-proxy-http=true \
    --enable-foreman-plugin-openscap \
    --enable-foreman-proxy-plugin-openscap \
    --enable-foreman-cli-openscap

5. Prepare realm

cd /etc/foreman-proxy
sudo foreman-prepare-realm admin realm-proxy@EXAMPLE.COM
<password prompt for admin>
sudo chown foreman-proxy: freeipa.keytab

6. Configure realm in foreman

sudo foreman-installer \
    --foreman-proxy-realm=true \
    --foreman-proxy-realm-principal=realm-proxy@EXAMPLE.COM

Actual Results: This fails saying to look at the proxy.log for detail of the failure. The proxy log has the error
[E] Disabling all modules in the group ['realm_freeipa', 'realm'] due to a failure in one of them: Gem loading error: cannot load such file -- xmlrpc

Expected Results: The foreman-installer completes successfully

Additional Info: I have found a work around

sudo scl enable tfm bash
gem install xmlrpc
exit
