[LINUX] A story about a beginner trying hard to set up CentOS 8 (procedure memo)

I want to use CentOS 8 for desktop / development (blender-python3.7, unity for linux (game engine)). Do not publish outside the LAN (WAN-> LAN port mapping is not performed on the router side) Almost the first time (I used it a little in a university circle about 5-10 years ago) To-do list

  1. Update to the latest BIOS before installation (because RDRAND is dead Ryzen 3 ASRock X570 Pro4 (BIOS v1.0))

  2. Partition (only one NVME m2 512GB) --MBR default -/ boot 1GB (If you have it, can you afford it? Now the kernel is about 100MB?

    • /(root)) 128GB -/ home rest (about 400GB?) -/ swap 4GB (with 32GB of RAM ...
  3. selinux

    • /etc/selinux/config -~~ SELINUX = permissive (only warning) ~~ --setebool -P antivirus_can_scan_system 1 (Allow selinux to scan for viruses (clamAV))
  4. Administrator account --sudo adduser adminhoge #You will be asked for your password on the way

    • sudo adduser adminhoge wheel
  5. Everyday account --adduser userhoge #You will be asked for your password on the way

  6. nvidiaDriver install (https://qiita.com/kkk627/items/9ab959421804341f215e) dnf update (without kernel source (kernbel-devel) and kernel)

    1. dnf groupinstall "Development Tools"
    2. dnf install libglvnd-devel elfutils-libelf-devel
    3. /etc/modprobe.d/blacklist-nouveau.conf
      • blacklist nouveau
      • options nouveau modeset=0
      • blacklist lbm-nouveau
    4. mv /boot/initramfs-(uname -r).img /boot/initramfs-(uname -r)-nouveau.img #backup with nouveau.img
    5. dracut --omit-drivers nouveau /boot/initramfs-$(uname -r).img $(uname -r) #make no nouveau.img
    6. reboot os In select mode a-> e quiet Behind (space) 3-> ctrl x
    7. sudo init 3 #CUI mode
    8. bash NVIDIA-Linux-x86_64****.run : y->n
  7. Add to nvidia-drm.modeset = 1 GRUB and grub2-update (https://wiki.archlinux.jp/index.php/NVIDIA) -> If you don't do this, you will not have enough privileges to log in? The driver crashes and the screen goes black, causing a recovery load. 8. reboot

  8. Edit> vm.swappiness = 10> /etc/sysctl.conf #swap suppression

  9. yum install epel-release

  10. dnf install dnf-automatic zsh dnf install java-11-openjdk.x86_64

  11. clamAV settings

Scan execution clamdscan -c ${CONFIG} ```
chmod +x /etc/cron.daily/clamdscan.sh systemctl enable clamd@scan systemctl start clamd@scan systemctl status clamd@scan (https://inaba-serverdesign.jp/blog/20170913/clamav_scan_virus_install.html) (https://qiita.com/bezeklik/items/4696e15c889ffff6bc41)

  1. Install from web: Google-chrome vscode (& minecraft client)
  2. Are you there? ./ zshrc https://news.mynavi.jp/article/zsh-10/

Work with sudo vs code from here --install the following in vscode - ms-ceintl.vscode-language-pack-ja - coenraads.bracket-pair-colorizer - ms-python.python --Ctrl + Shift + P-> configure display language-> Change the part written as "en" to "ja"

  1. dnf-automatic, but I want to update the kernel manually, update is security only --Edit excludepkgs = kernel *> /etc/dnf/automatic.conf --Edit apply_updates = yes> /etc/dnf/automatic.conf --Edit upgrade_type = security> /etc/dnf/automatic.conf

    • systemctl enable dnf-automatic.timer
    • systemctl start dne-automatic.timer
  2. (http://tooljp.com/linux/Redhat7/faqRedhat7/html/what-is-virbr.html) Somehow the virtual LAN is springing up without permission, so crush it.

    • dnf install libvirt-client.x86_64
    • virsh net-list --all
    • virsh net-autostart default --disable
  3. sshd

  1. py -3.7 -m venv py37env
  2. dnf install mesa-libGLU-devel.x86_64 --Without, unity did not start
    • ln -s /etc/ca-certificates/extracted/ca-
    • bundle.trust.crt /etc/ssl/certs/ca-certificates.crt -Certificate name? Seems to have changed and unity was throwing a compile error (v2018.4), so I linked it.
  3. chmod u+x ~/Downloads/UnityHubSetup.AppImage ./UnityHubSetup.AppImage
  4. Date gsettings set org.gnome.desktop.interface clock-show-date true
  5. Window button gsettings set org.gnome.desktop.wm.preferences button-layout appmenu: minimize, maximize, close

In / etc / sudoers %wheel ALL=(ALL) ALL But Make sure there is groups -> username wheel

Make sure that it is

sudo passwd -l root #root login seal (I was able to sudo if I was messed up with rescue from the USB that died here and I thought I was going to die. But clamdscan doesn't work without sudo, what should I do?

ps. dnf install pv ps.

https://qiita.com/takanemu/items/90ea4b938a979b0990b3

I wrote it in .xprofile but it didn't work, so I wrote it in .bashrc. Make the cache a RAMDisk. It seems that it will support if it complies with freedesktop.org (chrome etc.

ps. dual boot with windows

/etc/adjtime

UTC -> LOCAL

Specifying the cache directory

~/.bashrc



export XDG_CACHE_HOME=/dev/shm/.cache-$(whoami)
mkdir -p ${XDG_CACHE_HOME}
chmod 700 ${XDG_CACHE_HOME}
