Posts here are mostly step-by-step guides on how to replicate something I have set up in the past. Read over my About page to see how I show commands/output and read the disclaimer.
Before I had my Kickstart templates created, I went through manual installs. This guide is here to remind me of some steps to keep consistent systems.
Base OS Install
Boot the installer.
If within range of the local mirror, select HTTP as the mirror and use this URL:
http://s10-deploy/mirrors/centos/6/os/x86_64/
DHCP Hostname Fix
The hostname is not correctly registered with DHCP by default. We need to add a line to /etc/sysconfig/network in order for the hostname to resolve from other LAN machines.
[root]$ echo "DHCP_HOSTNAME=`hostname`" >> /etc/sysconfig/network
The file should now look something like this:
[root]$ cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=dev-centos-03 DHCP_HOSTNAME=dev-centos-03
Some Config Settings
Manually download some configs.
[root]$ wget https://raw.github.com/atw527/dotfiles/master/.vimrc [root]$ cp .vimrc /etc/skel/
Change some bash prompts. If doing the server install, no users were created yet. Update your root prompt:
[root]$ echo "PS1='[\[\e[01;31m\]\u@\h \w\[\e[0m\]]\$ '" >> ~/.bashrc
Update the skel prompt for users:
[root]$ echo "PS1='[\u@\h \w]\$ '" >> /etc/skel/.bashrc
Logout and back in to see the new prompt.
Local Mirror and Updates
I have a local mirror. I believe the correct way to set a local mirror is in the /etc/yum.repos.d/CentOS-Base.repo. The file needs to have the baseurl lines uncommented and changed to the local mirror path.
[root]$ sed -i s@#baseurl=http://mirror.centos.org@baseurl=http://mirror/mirrors@g /etc/yum.repos.d/CentOS-Base.repo
Consider disabling fastmirror.
[root]$ vim /etc/yum/pluginconf.d/fastestmirror.conf
Clean any cached yum files:
[root]$ yum clean all
Import the main key to prevent a warning on the first update:
[root]$ rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
Now let’s run a system update. Make sure the mirrors used is the local server. The update mirror will show up in the first few lines as shown below.
[root]$ yum update Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile * base: s10-deploy * extras: s10-deploy * updates: s10-deploy ...
RPMForge Mirror Setup
I prefer htop for my text-based process manager. It is unfortunately not available in the main repositories.
[root]$ wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.`uname -i`.rpm
Import the key.
[root]$ rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
Verify the package.
[root]$ rpm -K rpmforge-release-0.5.2-2.el6.rf.*.rpm
Install it.
[root]$ rpm -i rpmforge-release-0.5.2-2.el6.rf.*.rpm
Install htop.
[root]$ yum install htop
