Red Hat Enterprise Linux 9 e se e lokollotsoe 'me tsena ke litaba tsa eona

Red Hat e phatlalalitse ho lokolloa ha mofuta o mocha oa kabo ea hau "Red Hat Enterprise Linux 9" eo, ho latela potoloho ea tšehetso ea lilemo tse 10 bakeng sa kabo ea RHEL 9, e tla tsoelapele ho fihlela 2032 le hore lintlafatso tsa RHEL 7 li tla tsoelapele ho lokolloa ho fihlela la 30 Phuptjane 2024, RHEL 8 ho fihlela la 31 Motšeanong 2029.

Kabo ea Red Hat Enterprise Linux 9 e hlokomeleha ka ho fallela ha eona ts'ebetsong ea nts'etsopele e bulehileng haholoanyane. Ho fapana le makala a fetileng, setsi sa sephutheloana sa CentOS Stream 9 se sebelisoa e le motheo oa ho aha kabo.

Ke eng e ncha ho Red Hat Enterprise Linux 9

Phetolelo ena e ncha ea kabo e fihla le Linux kernel 5.14, RPM 4.16 ka ts'ehetso ea taolo ea botšepehi ka fapolicyd, GNOME 40 le laeborari ea GTK 4, ntle le ho falla ha kabo ho Python 3, ho ba ka har'a mofuta ona o mocha oa RHEL mofuta oa kamehla oa python 3.9 le ho tšoaea pheletso ea Python 2 joalo ka ha e khaotsoe.

Ka ho sa feleng, GRUB boot menu e patiloe haeba RHEL e le eona feela kabo e kentsoeng tsamaisong le haeba bootle ea ho qetela e atlehile. Ho hlahisa menu nakong ea boot, tšoara feela konopo ea Shift kapa konopo ea Esc kapa F8 ka makhetlo a 'maloa. Ea bootloader e fetoha, ho boetse ho hlokomeloa sebaka sa lifaele tsa tlhophiso tsa GRUB bakeng sa meralo eohle ea meralo e tšoanang /boot/grub2/ directory (faele ea /boot/efi/EFI/redhat/grub.cfg e se e le symlink ho /boot/grub2/grub.cfg), tseo. sistimi e ts'oanang e kentsoeng e ka qalisoa ho sebelisoa EFI le BIOS.

Ka ho sa feleng, taolo e le 'ngoe e kopaneng ea sehlopha (cgroup v2) e lumelletsoe. Cgroups v2 e ka sebelisoa, mohlala, ho fokotsa mohopolo, CPU, le tšebeliso ea I / O. Phapang e ka sehloohong pakeng tsa lihlopha tsa v2 le v1 ke tšebeliso ea lihlopha tse tloaelehileng tsa lihlopha bakeng sa mefuta eohle ea lisebelisoa, ho e-na le lihlopha tse arohaneng tsa kabo ea CPU, tsamaiso ea memori, le I / O. Maemo a arohaneng a ile a baka mathata ho hlophisa tšebelisano lipakeng tsa bakhanni le litšenyehelo tse ling tsa lisebelisoa tsa kernel ha ho sebelisoa melao bakeng sa ts'ebetso e rehelletsoeng ka maemo a fapaneng.

Ts'ebetso ea SELinux e ntlafalitsoe haholo le ho fokotsa tšebeliso ea memori. Ts'ehetso e tlositsoeng bakeng sa ho beha "SELINUX = e holofetse" ho tima SELinux ho / etc/selinux/config (setting e boletsoeng hona joale e sitisa ho kenya leano feela, 'me ha e le hantle ho thibela ts'ebetso ea SELinux hona joale ho hloka ho fetisa "selinux = 0" ho kernel).

Hape hoa totobatsoa hore e ekelitse tšehetso bakeng sa khokahano ea nako e nepahetseng e ipapisitseng le protocol ea NTS (Network Time Security), e sebelisang likarolo tsa lisebelisoa tsa bohlokoa tsa sechaba (PKI) mme e lumella ts'ebeliso ea TLS le encryption e netefalitsoeng ea AEAD (Authenticated Encryption with Associated Data) bakeng sa ts'ireletso ea cryptographic ea tšebelisano ea bareki le seva holima protocol ea NTP ( Network Time. Tsamaiso). Seva ea chrony NTP e ntlafalitsoe hore e be mofuta oa 4.1.

Ho phaella ho sena, ho totobatsoa hore tšehetso ea liteko e fanoeng (Tech Preview) bakeng sa KTLS (ts'ebetso ea boemo ba TLS kernel), bohlale sgx (Keketso ea Ts'ireletso ea Software), DAX (Direct Access) bakeng sa ext4 le XFS, tšehetso bakeng sa AMD SEV le SEV-ES ho hypervisor ea KVM.

Ea liphetoho tse ling tse hlahelletseng:

  • E kentse tšehetso ea liteko bakeng sa WireGuard VPN.
  • Ka kamehla, ho kena ha SSH joalo ka motso ho koetsoe.
  • E tlositsoe sephutheloana sa mangolo a marang-rang, NetworkManager e lokela ho sebelisoa ho lokisa likhokahano tsa marang-rang.
  • Ts'ehetso bakeng sa sebopeho sa tlhophiso ea ifcfg e bolokiloe, empa NetworkManager e na le sebopeho sa kamehla se thehiloeng ho faele ea bohlokoa.
  • Liphutheloana tsa seva tse ntlafalitsoeng Apache HTTP Server 2.4.48, nginx 1.20, Varnish Cache 6.5, Squid 5.1.

Kamora nako, haeba o rata ho tseba ho eketsehileng ka eona, o ka sheba lintlha Ka sehokela se latelang.
