Installation of Red Hat Linux

DataBreeze has been developed and tested on RedHat Linux (7.2), yet most versions of Unix should work similarly. No versions of microsoft windows are supported due to poor security and instability. We typically apply all current version updates and recompile using the latest stable kernel source. OpenSSL is required for Apache SSL functionality and OpenSSH (secure shell). Unnecessary services should be shut down and Iptables firewalling should be activated.
The following examples are suggestions only and may not be appropriate for your system needs.
Install RedHat - Using the latest RedHat distribution, install Linux. Make sure to install developmental and software tools for compilation of Apache and the Linux Kernel.
Download Updates for your version of RedHat, install and reboot.
|
Download updates example
|
# ftp -i updates.redhat.com
- anonymous - you@yourmail.com
# cd 7.2/en/os/i386
mget *.rpm
|
|
Install updates using RPM
| |
# rpm -Fvh *.rpm
|
Download the latest stable Kernel. Unpack, configure and compile. Be sure to enable netfilter/iptables during configuration. Reboot after installation of the new Kernel.
Use the 'chkconfig' command to disable the startup of all non-essential services.
|
Service shutdown Examples:
|
# service portmap stop
# chkconfig nfs off
# chkconfig nfslock off
# chkconfig netfs off
# chkconfig xinetd off
# chkconfig ipchains off
# chkconfig ipchains --level 345 on
# chkconfig sendmail off
# chkconfig pppoe off
# chkconfig isdn off
# chkconfig rawdevices off (unless using Oracle or similar)
|
Use the service command to stop any unecessary services that are currently running.
|
Service shutdown Examples:
|
# service portmap stop
# service nfs stop
# service nfslock stop
# service netfs stop
# service xinetd stop
# service ipchains stop
# service sendmail stop
# service pppoe stop
# service isdn stop
# service rawdevices stop (unless using Oracle or similar)
|
Configure a an IPTables script, load and save it for use on restart.
|
Simple IPTables example script
|
# mv iptables.script /etc/sysconfig/
# chmod +x /etc/sysconfig/iptables.script
# /etc/sysconfig/iptables.script
# iptables-save > /etc/sysconfig/iptables
# services iptables restart
