Centos 6.4 - Installing op sys correctly without additional stuff ?

Smaily
In CentOS 5 version you could choose, not to install Gnome DeskTop and other things that you don't need with cPanel. Apparently in CentOS 6.4 it simply force installs everything that is not needed aswell without asking. Used graphical install mode. Not familiar with any other. Anyone have good knowledge how to properly do CentOS 6.4 install before installing cPanel on the system ? I have seen documentation that states about writing config file on the bootable CD. Apparently so far I have not figured out how to correctly make bootable CentOS as ways I tried, didn't let to boot written CD afterwards. Meybe a guide for dummys would do starting which package to download. What kind of CD writing software to use and how to write on CD. Along with how to take out things you don't need and what to take out. Below some info I have gathered, some from cPanel support. I'm using 64bit system myself. But I do have 32GB RAM on the system. Previously x64_86 seemed to support it but google tells me Kernel_PAE 32bit op sys only supports more then 4GB RAM. SSH command showed correctly 32GB on the system.

Hostname must be fully qualified hostname and should not be using localhost rather than the server's main IP. # cat /etc/hosts # hostname -f # hostname -i Setup a hostname and set the hostname to use the main server IP. Finally, you may wish to change the resolver to a public one such as Google's: # cat /etc/resolv.conf This would be the following instead in /etc/resolv.conf file: nameserver 8.8.4.4 nameserver 8.8.8.8 Installing cPanel using the "screen" command without the quotes allows installing without worrying about losing your session. This works in SSH on any client so long as screen is installed. If it is not installed, it can be via "yum install screen" command without the quotes. Mounting external drive: 1. open the terminal window with the root account. 2. download rpmforge for centos 6 to your system: wget 4. just install/update the package fuse-ntfs-3g: # yum update fuse-ntfs-3g 5. mount your units: # mount -a cPanel install takes approximately 284 minutes on Dual Core processor with 16GB RAM.

SSH - wheelgroup user and state port, ip. There is security issue with Demo account of cpanel. If you dont set wheelgroup user before you create Demo account then somehow some exploit is able to gain SSH access as normal shell to Demo account and erease files from account that username is known to. Also able to terminate database. Some firewall may help aswell. I just put everything here I believe is needed to know for installing.

    You could just start with CentOS 6.4 x86_64 Minimal:

    I'd second what's said above, the minimal installs are usually less of a headache (apart from that one a while back that was so minimal it didn't even come with networking ;) ) With regards what you have under "Mounting external drive:" unless this is something you need to do (i.e. copy a lot of data off an existing NTFS drive directly attached to the server) you might be best off avoiding adding another repo to centos and transferring the data over the network, while rpmforge shouldn't break anything in base if you're new to things the less different avenues of potential confusion / breakage the better. With regards firewall, if you aren't working with a hardware firewall doing both ingress and egress filtering something like CSF is most certainly a good idea [url=http://configserver.com/cp/csf.html]ConfigServer Security & Firewall (it'll also help you monitor resource usage etc on your server).

    I always use CentOS minimal install as Mike recommend. After installing you update with yum and get some additional software and start install from cPanel. I assume you know how to install CentOS6.4, then after that you do as follow: vi /etc/selinux/config SELINUX=disabled * Check all your network settings and hosts files.... yum remove NetworkManager yum update yum install wget nmap mlocate prelink rdate yum-utils yum clean all # reboot DNSonly: cd /home wget -N sh latest # Installer starts, get a coffee, it can take a while: half hour to hour # Install CSF firewall. cd /root touch /var/log/lfd.log wget
