CentOS 7 is centrally supported at SLAC for the following platforms:
Although RHEL 7 is also available if required by your application for support, CentOS 7 is preferred and recommended instead.
These are the steps to install and configure CentOS 7 at SLAC for a headless bare metal server, or virtual machine in VMware or OpenStack:
Install CentOS 7 using either the Minimal or the DVD ISO available here (available on the SLAC network or VPN):
http://yum.slac.stanford.edu/iso/centos/7/
Log into your new CentOS 7 host.
Become root by using sudo or /bin/su.
Install Chef by running this command as root:
curl http://yum.slac.stanford.edu/go-chef | /bin/sh
Before you exit your root prompt, you need to modify this file:
/etc/security/access.netgroup.conf
Add a line that looks like this (replace 'ksa' with your username):
+ : ksa : ALL
Make sure to add that line above the last line. Here is an example of what the file might look like if you wanted to grant login access to users ksa and vanilla:
+ : root : LOCAL 134.79.0.0/16 172.16.0.0/12
+ : ksa : ALL
+ : vanilla : ALL
+ : @u-scs-staff : ALL
- : ALL : ALL
Before you exit your root prompt, create a sudoers entry for yourself inside the /etc/sudoers.d directory.
You can copy and paste the following (replace 'ksa' with your username):
cat > /etc/sudoers.d/user-ksa << EOF
ksa ALL=ALL
EOF
