Installation of CentOS 6 on t9h Goal: Install centos 6.10 on t9h computer. The original simtac PC died in 2021/06. Only refurbished part avaiilable...so found/purchased a PC with appropriate slot as a replacement. Will upgrade simtac PC/Software to this new computer. Date: 2018/10 1.

Turn off filewall: sudo system-config-firewall-tui # disable the network manager. service NetworkManager stop chkconfig NetworkManager off system-config-network vi /etc/sysconfig/network-scripts/ifcfg-eth0 ## make sure ONBOOT=yes /boot/grub/menu.lst - disable 'hiddenmenu'; remove 'rhgb quiet' reboot # because CENTOS 6 was EOL, need to fix repo name for updates, installs. # used www.getpagespeed.com CentOS vault repository: curl https://www.getpagespeed.com/files/centos6-eol.repo --output /etc/yum.repos.d/CentOS-Base.repo yum update reboot #NOTE: Had some trouble getting the network setup (and stable) so went ahead with # yum update, and will redo network configuration later. yum groupinstall 'Development Tools' 'KDE Desktop' 'Office Suite and Productivity' yum install gnuplot gsl gsl-devel vnc vnc-server ImageMagick \ tk expect qt-devel rdist control-center-extra dump telnet \ mysql MySQL-python sox hg mutt make droot, mroot fix root password. move /home/irtf to /home2/irtf (/home will be a automount). assign project passwd. # using System->Preferenc->Network Connection, I deleted some auto ethenet devices, and review the static IP. ... networking is ok now. IRTF Setup - allow tcs3, denault on auto only (similar to t1hilo setup) /etc/hosts - add key IRTF server /etc/ntp.conf - use IRTF NTP servers, and enable ntpd services: system-config-services /etc/yp.conf - configure and enable NIS: system-config-authentication, AND check yp.conf /etc/nsswitch.conf - Limited nis usage /etc/group - add staff 500, project 501. NIS client setup: chkconfig rpcbind on chkconfig ypbind on /etc/init.d/ypbind start nsf client setup: vi /etc/idmapd.conf Add "Domain=ifa.hawaii.edu" chkconfig rpcbind on chkconfig rpcidmapd on chkconfig nfslock on chkconfig netfs on /etc/auto.master, automap, auto.home - custom tcs setup to allow only: tcs(remote), to (local - not needed for t9h). - make /home2/nologin - only allow file based autofs make links for automounts: cd / ln -s /netdisks/htdocs ln -s /netdisks/irtf.backup rc.local - add line for screen blank: /usr/bin/setterm -blank 0 create remainding partitions using fdisk: fdisk /dev/sda sda2 as /r2 50G sda3 as /aux (remainder ~364G) Format: mkfs.ext4 -v -m 3 /dev/sdaX add to /etc/fstab - but commented out, don't need them. Now you have the computer on NIS, with tcs3 login. SimTac Setup Information on the simtac application is here: /home/tcs3/src/tcs3/simtac2
