Installation of RL8 on IDA PC
Goal: Install RockyLinux 8 (new PC/new install).
Purchased 9 computer for lab(2), ishell(3), spex(3), and mirsi(1).
This document describes the initial installation of RL8 on the systems.
Date: 2022/07
1. Hardware
ID1/ID2, Mirsi, and iSHELL computers:
ASUS Prime B560-PLUS MB, i5-11400 CPU, 16GB DDR4 RAM, 500GB SSD
650W PS, Thermalake V100 case/Antech VSK4000 case.
Build to order system from MagicMicro.com purchased in 2022/07.
Built the Spex computers (same MB, CPU) purchased on 8/2022:
ASUS Prime B560-Plus LGA 1200 ATX, i5-11400 CPU,
Noctua NH-U9S Cooler, Corsair LPX 16GB (2x8GB) DDR4 3200MHz,
Samsung 870 EVO 500GB 2.5 SSD, Antec VSK4000E-U3 Case.
SeaSonic S12III 650W P/S.
BIOS changes:
Boot-> Fast Boot -> disabled.
Advance -> AMP configuration -> Restore AC power loss -> Power On
2. Linux installation
Make usb bood device with RockyLinux 8.6-x86_64-dvd.iso + rufus 3.19.
Boot with usb
- Date and Time: select Pacific/Honolulu timezone
- Software Selection: Select workstation: add GNOME apps, Office Suite, Development tool, Graphical Admin Tool
Scientific support, system tools.
- Instatation Destination: Select disk, and do Custom Partition:
Standard partition
1. sda1 /boot/efi 200M efi system partition
2. sda2 / 60G ext4
- set a root password.
- create a local irtf user.
- Network&Hostname: static IP, ida # forgot on 1st installation. Will set to static later...
Eject USB and reboot
1st boot:
Turn off selinux:
vi /etc/selinux/config
SELINUX=disabled
Stop & Turn off filewall:
systemctl stop firewalld
systemctl disable firewalld
dnf upgrade # same as yum --obsoletes update
reboot
(one PC frozed after dnf upgrade/reboot. Updated BIOS from 1410 to 1601 fixed it).
Setup the static IP using nmtui (since I forgot to set static IP at installation).
dnf install net-tools
nmtui
- set IP, gateway, DNS Server, search domains. And Automatically connect.
- also used nmtui to set hostname: ida1.ifa.hawaii.edu
reboot to insure it come up correctly.
Insure we installed everything we want:
dnf groupinstall "Development Tools" "Graphical Administration Tools" \
"Scientific Support" "System Tools" "Office Suite and Productivity"
dnf install nano net-tools gnuplot gsl gsl-devel tigervnc tigervnc-server \
expect mercurial mutt gtk2-devel hplip samba ypbind rpcbind gtk3-devel \
tcsh autofs ntpstat xterm mariadb dump gnome-tweaks lm_sensors libusb \
ncurses-devel
Now you have a complete working system with desktop.
3. Setup as basic IRTF clients
Accounts:
move root to /root/root; make mroot,droot
update root passwd to standard IRTF root.
Only if created local user:
move irtf (local user) to /home2, as /home will be an automount
NTP:
date - to show timezone. if wrong: timedatectl set-timezone Pacific/Honolulu
dnf -y install chrony ntpstat
# specify local ntp servers
vi /etc/chrony.conf
#pool 2.centos.pool.ntp.org iburst
server duke.ifa.hawaii.edu iburst
server goblin.ifa.hawaii.edu iburst
pool ntproundtop.hawaii.edu iburst maxsources 3
server irtfgps2.ifa.hawaii.edu iburst
#enable chronyd
systemctl enable --now chronyd
# chronyc can be used to show status:
chronyc sources # displayinfo about current sources
chronyc sourcestats # Display estimation info about current sources
chronyc tracking # display system time information
chronyc activity # show the NTP sources
Setup as NIS Client:
vi /etc/yp.conf # add the following lines
domain irtf.ifa.hawaii.edu server goblin
vi /etc/hosts # define the NIS servers
authselect select nis
systemctl enable --now rpcbind ypbind
Install NFS
vi /etc/idmapd.conf
Domain=ifa.hawaii.edu
Enable service:
systemctl enable rpcbind
systemctl enable nfs-server
systemctl enable autofs
Start service:
systemctl start rpcbind
systemctl start nfs-server
systemctl start autofs
make links for automounts instrurments:
ln -s /netdisks/htdocs /htdocs
ln -s /netdisks/starcatalogs4 /starcatalogs4
ln -s /netdisks/irtf.backup /irtf.backup
ln -s /netdisks/scrs1 /scrs1
ln -s /netdisks/benchmark /benchmark
Now you have IRTF client with YP,NFS,Automount. IRTF accounts are working.
4. More setup
finish setting up /r3, /aux - only part of the disk was partitioned, formatted so ..
fdisk /dev/sda
used 'n' to create 60G for /r3
used 'n' to create remainder (345.6G) for /aux
'w' to write and exit
mkfs.ext4 -v -m 2 /dev/sda3
mkfs.ext4 -v -m 2 /dev/sda4
blkid /dev/sda3 # used to print UUID
blkid /dev/sda4
mkdir /r3; mkdir /aux # to ceate mounts
vi /etc/fstab # add mounts to fstab: used /dev/sdaX, ont UUID
/dev/sda3 /r3 ext4 defaults 1 2
/dev/sda4 /aux ext4 defaults 1 2
smartd:
Add devices to scan in conf:
vi /etc/smartmontools/smartd.conf
#DEVICESCAN ...
/dev/sda -a -d sat -o on -S on -s (S/../.././07|L/../../6/09) -R 194 -m root
To enable service:
systemctl enable smartd.service
To start service:
systemctl start smartd.service
# you can review a list of recent test with
smartctl -a /dev/sda
5. IRTF Instrument setup
/etc/rc.local Enable & add commands
To enable
chmod u+x /etc/rc.d/rc.local
systemctl start rc-local
Add the following lines to /etc/rc.local
#
# change the limits for the mqueues using the /proc file system for IRTF instrument software
# msg_max default is 10, need 40.
# msgsize_max default is 8192, 1024 is required.
#
echo "40" > /proc/sys/fs/mqueue/msg_max
echo "1024" > /proc/sys/fs/mqueue/msgsize_max
Set up 192.168.x.x IP address:
This method for using ifcfg-eno1:0 did not work:
cd /etc/sysconfig/network-scripts
vi ifcfg-eno1:0 # copy format for another RL8 computers
so I used network manager to setup the 192.168 address, it add these line to ifcfg-eno1:
IPADDR1=192.168.110.142
PREFIX1=16
also the link appears to be 100mb. (changing the cable make it 1000mb)
/usr/local/bin installs:
Installed DV from /home/s2/src/dv.
Needs: bigdogio dv dvio guidedogio ielog morisio t3io
Make sure python works for /usr/local/bin/ielog:
alternatives --set python /usr/bin/python3
pip3 install pymysql
Setup sudo for bigdog/guidedog XUI can chmod and chown for /scrs1 using
its xui/set_ownership_and_readonly script. Only needed for bigdog, guidedog, not littledog.
# visudo
added:
#- allow bigdog/guidedog to run set_ownership_and_readonly as root
bigdog ALL=NOPASSWD : /bin/chmod, /bin/chown
guidedog ALL=NOPASSWD : /bin/chmod, /bin/chown
s2 ALL=NOPASSWD : /bin/chmod, /bin/chown
# visudo -c
