Installation of CentOS 8 Goal: Install centos 8 on tx2 (test system to port TCS to CentOS8). In 2018, tcs3 was ported and run on centos7, but never depolyed due to HA drive issues, and the sense CentOS7 wasn't going to see deployment on the IRTF. Setup this computer with CentOS8 to begin test the TCS on CentOS8. Date: 2019/10 1. HARDWARE purchased by denault from newegg, amazon, mwave on 2018/01: GA-B250M-D3H LGA-1151, I5-7400 CPU, 16GB RAM (DDR4 2133), 500GB HD(WD Black WD50003AZEX). DVD Seasonic FOCUS Pluse 550FX P/S case: Chenbro RM41300-F1 (mwave) 2. DVD Install and update Created USB boot disk using CentOS-8-x86_64-1905-dvd1.iso using Win32DiskImager. desired partitions are: sda1 210M /boot/efi # efi system parition sda2 52G / # centos8 root sda3 52G /r3 # unused sda4 395G /aux # Selected bios boot menu: usb (UEFI) Software selection: GNOME Desktop Installation destination: sda, I will configure partitioning manual parititon: /boot/efi 210M sda1 / 52G sda2 (will do other later, as installer want to assign sdaX ). manual config ethernet. start installation. made local user 'irtf', during setup INSTALLATION FROZE about 85%. Tried again. with Server+GUI install. This worked! 1st Boot Stop & Turn off filewall: systemctl stop firewalld systemctl disable firewalld Turn off selinux: vi /etc/selinux/config SELINUX=disabled. yum update reboot Insure you have everything you want: dnf groupinstall "Workstation" "Development Tools" \ "Graphical Administration Tools" "Scientific Support" "System Tools" dnf install nano net-tools gnuplot gsl gsl-devel tigervnc tigervnc-server \ expect mercurial mutt gtk2-devel hplip samba ypbind rpcbind gtk3-devel \ mariadb tcsh autofs ntpstat xterm pmac driver support: dnf install elfutils-libelf-devel Now you have a complete working system/desktop. 3. IRTF Client Setup Setup Chrony - the NTP client vi /etc/chrony.conf comment out pool 2.centos.pool.ntp.org iburst, and add: 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 to insure chronyc was enabled: systemctl status chronyd to start and enable : systemctl start chronyd systemctl enable 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 ntpstat Accounts: make droot, mroot update root pw (still i-------) Only if created local user: move irtf (local user) to /home2, as /home will be an automount Setup as NIS Client: ypdomainname irtf.ifa.hawaii.edu vi /etc/hosts # define the NIS servers vi /etc/yp.conf authselect select nis systemctl enable --now rpcbind ypbind Install NFS vi /etc/idmapd.conf Domain = ifa.hawaii.edu Enable: systemctl enable rpcbind #systemctl enable nfs-server systemctl enable autofs Create netdisk automont links: ln -s /netdisks/htdocs /htdocs # create needed netdisks links ln -s /netdisks/irtf.backup /irtf.backup Now you have IRTF client with YP,NFS,Automount. IRTF accounts are working. 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 finish setting up /r3, /aux fdisk /dev/sda used 'n' to create 53G for /r3 used 'n' to create remainder (360.6G) for /aux 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 4. TCS Custom Set Up Setup 192.168 address cd /etc/sysconfig/network-scripts vi ifcfg-enp0s31f6:0 DEVICE=enp0s31f6:0 ONBOOT=yes BOOTPROTO=none IPADDR=192.168.110.232 PREFIX=16 ip addr show # should show 2 IP attached to your device. TO account, restrict logins to a select few on the computer 1. custom /etc/nsswitch.conf for NIS to restrict who can login to the TCS computers: "file" only for automount vi /etc/authselect/user-nsswitch.conf #automount: files sss automount: files authselect apply-changes # didn't applycchanges authselect select nis # but ran this, then changes applied. 2. setup /etc/auto.home and /etc/automap file based automounts vi /etc/auto.master #+auto.master # only file based autofs for TCS /netdisks /etc/automap /home /etc/auto.home 3. Setup local /home2/to' account to run the TCS application. ( not /home/to is in auto.home) to:x:6028:501:Telescope Operator:/home/to:/bin/tcsh Setup local /home2/nologin for users in nis passwd, but not allow on TCS. Now login are limited to certain accounts, and local 'to' account works. /home/to setup: pulse audio, /etc/group fixes Finish setting up /home/to, get audio to run via a ssh login. 1. setup /home/to's links (data, current), and /bin files. 2. vi /etc/group add "to,tcs3" to audio:63 group staff:x:500:tcs3 project:x:501: Login as 'to' to the console/desktop and set the volume on the audio device. Now using "ssh -x" the ssh login/IC can play sounds using, ie: aplay /home/tcs3/dev/ic/audio/wav/next_obj.wav Copy /aux/catalogs4 to new computer # copy from t1hilo to local system: rsync -az -v -e ssh --delete --numeric-ids t1hilo:/aux/catalogs4 /aux/ /usr/local/bin # for apeio need rpcgen, and libtirpc-devel (replacment for sun's rpc lib). dnf --enablerepo=PowerTools install rpcgen dnf install libtirpc-devel #install the following /usr/local/bin binaries, scripts apeio - /home/tcs3/src/tcs3/embeddedx86/apeio.64/ ielog, ielog_2hr.sh, ielog_query - /home/ida/src/ielog alternatives --set python /usr/bin/python2 # set the default verion of python dnf install python2-PyMySQL # for import pymysql dnf install python3-PyMySQL # for import pymysql isd_q1 - /home/tcs3/src/tcs3/clients/iSD-TH/ rioquery - /home/tcs3/src/tcs3/clients/rio/ smokeyio - /home/smokey/current/ic/icio/ t3io - /home/tcs3/src/tcs3/clients/t3io/ /etc/rc.local stuff /etc/rc.local Enable & add commands To enable chmod u+x /etc/rc.d/rc.local systemctl start rc-local Add the following lines: # # if you screen blanck after 10 min or so, this stops it # /usr/bin/setterm -blank 0 # # change the limits for the mqueues using the /proc file system. # msg_max default is 10, need 40. # msgsize_max default is 8192, need 1024 is ok. # echo "40" > /proc/sys/fs/mqueue/msg_max echo "1024" > /proc/sys/fs/mqueue/msgsize_max # # load the tcs device drivers: pmac.ko # sleep 8 # since systemd runs in parallel (need delay) mknod --mode=666 /dev/pmac c 66 0 insmod /home/to/current/drivers/pmac/pmac.ko -------------------------------------------------------------------------------------- problems with sound: show setting: pactl list sinks ssh for IC "Mute: yes" , to unmute: sh -c "pactl set-sink-mute 0 false" Increase volume in IC xterm: sh -c "pactl set-sink-mute 0 false ; pactl set-sink-volume 0 +5%" Set defaults: xterm: cat ~/.config/pulse/default.pa .include /etc/pulse/default.pa # Set volume to 50% on boot set-sink-volume 0 32768
