I-Red Hat ibhengeze ukukhululwa kwe Inguqulelo entsha yosasazo lwakho "Red Hat Enterprise Linux 9" leyo, ngokungqinelana nomjikelo wenkxaso weminyaka eli-10 wokusasazwa kwe-RHEL 9, iya kuqhubeka de kube ngu-2032 nokuba uhlaziyo lwe-RHEL 7 luya kuqhubeka nokukhutshwa kude kube nguJuni 30, 2024, i-RHEL 8 de kube nguMeyi 31, 2029.
Ukuhanjiswa kweRed Hat Enterprise Linux 9 kuphawuleka ngokuhamba kwayo kwinkqubo yophuhliso evuleleke ngakumbi. Ngokungafaniyo namasebe angaphambili, isiseko sephakheji ye-CentOS Stream 9 sisetyenziswa njengesiseko sokwakha ukuhanjiswa.
Yintoni eNtsha kwiRed Hat Enterprise Linux 9
Olu guqulelo olutsha lonikezelo lufika kunye ne I-Linux kernel 5.14, RPM 4.16 ngenkxaso yolawulo lwemfezeko ngokusebenzisa i-fapolicyd, I-GNOME 40 kunye nethala leencwadi le-GTK 4, ukongeza kwimfuduko yonikezelo kwiPython 3, ekubeni kolu guqulelo lutsha lweRHEL uguqulelo olungagqibekanga lwe Python 3.9 kunye nokumakisha ukuphela kwePython 2 njengoko iyekisiwe.
Ngokuzenzekela, Imenyu yokuqalisa ye-GRUB ifihliwe ukuba i-RHEL kuphela konikezelo olufakelweyo kwindlela kwaye ukuba isiqalo sokugqibela siphumelele. Ukubonisa imenyu ngexesha lokuqalisa, vele ubambe iqhosha le-Shift okanye iqhosha le-Esc okanye le-F8 amaxesha amaninzi. Ye utshintsho lwe-bootloader, nayo iyaphawulwa indawo yeefayile zoqwalaselo zeGRUB kuzo zonke izakhiwo kwi-/boot/grub2/ directory (i/boot/efi/EFI/redhat/grub.cfg ifayile ngoku isymlink ukuya /boot/grub2/grub.cfg), ezo. inkqubo efakiweyo efanayo inokuqaliswa ngokusebenzisa i-EFI kunye ne-BIOS.
Ngokuzenzekela, Uluhlu lweqela elinye elidityanisiweyo (iqela v2) yenziwe. Amaqela e-v2 angasetyenziswa, umzekelo, ukunciphisa imemori, i-CPU, kunye nokusetyenziswa kwe-I / O. Umahluko ophambili phakathi kwamaqela v2 kunye ne-v1 kukusetyenziswa koluhlu lweqela eliqhelekileyo kuzo zonke iintlobo zemithombo, kunoluhlu oluhlukeneyo lolwabiwo lwe-CPU, ulawulo lwememori, kunye ne-I/O. Uluhlu oluhlukeneyo lwemigangatho ludale ubunzima ekuququzeleleni intsebenziswano phakathi kwabaqhubi kunye neendleko ezongezelelweyo zemithombo ye-kernel xa kusetyenziswa imithetho yenkqubo echazwe kwii-hierarchies ezahlukeneyo.
Kuphuculwe kakhulu ukusebenza kwe-SELinux kunye nokunciphisa ukusetyenziswa kwememori. Isusiwe inkxaso yokuseta "SELINUX=ikhubaziwe" ukukhubaza i-SELinux kwi/etc/selinux/config (ulungiselelo olukhankanyiweyo ngoku luvala ukulayisha umgaqo-nkqubo kuphela, kwaye eneneni ukukhubaza ukusebenza kwe-SELinux ngoku kufuna kudlule "selinux=0" kwikernel).
Kuyacaciswa ukuba inkxaso eyongeziweyo yolungelelwaniso lwexesha oluchanekileyo olusekwe kwiprothokholi ye-NTS (Inethiwekhi yoKhuseleko lweXesha), esebenzisa izinto zesiseko esingundoqo sikawonke-wonke (PKI) kwaye ivumela ukusetyenziswa kwe-TLS kunye ne-encryption eqinisekisiweyo ye-AEAD (iAuthenticated Encryption with Associated Data) yokukhusela i-cryptographic ye-cryptographic yentsebenziswano ye-server-server phezu kwe-NTP protocol (Ixesha leNethiwekhi Umgaqo-nkqubo). Iseva ye-NTP yekhrony ihlaziywe kuguqulelo lwe-4.1.
Ukongeza koku, kugxininiswe ukuba inkxaso yovavanyo enikezelweyo (Tech Preview) ye KTLS (ukuphunyezwa kwenqanaba lekernel ye-TLS), intel sgx (Izandiso zoKhuseleko lweSoftware), Dax (Ukufikelela ngokuthe ngqo) kwi-ext4 kunye ne-XFS, inkxaso ye-AMD SEV kunye ne-SEV-ES kwi-hypervisor ye-KVM.
Olunye utshintsho ezibalaseleyo:
- Inkxaso yovavanyo eyongeziweyo yeWireGuard VPN.
- Ngokungagqibekanga, ukungena kwe-SSH njengengcambu kuvaliwe.
- Ikhutshiwe iphakheji yescripts womnatha, NetworkManager kufuneka isetyenziswe ukuqwalasela umdibaniso womnatha.
- Inkxaso ye-ifcfg yoqwalaselo ifomathi igciniwe, kodwa i-NetworkManager inefomathi engagqibekanga esekwe kwifayile engundoqo.
- Iiphakheji zeseva ezihlaziyiweyo ze-Apache HTTP Server 2.4.48, nginx 1.20, Varnish Cache 6.5, Squid 5.1.
I-DBMS ehlaziyiweyo i-MariaDB 10.5, i-MySQL 8.0, i-PostgreSQL 13, i-Redis 6.2. - I-SSSD (IiNkonzo zoKhuseleko lweSistim iDaemon), iinkcukacha zelogi zonyusiwe.
- Inkxaso ye-IMA yandisiwe
Okokugqibela, ukuba unomdla wokwazi okungakumbi ngayo, unokujonga kwiinkcukacha Kule khonkco ilandelayo.
Fumana iRed Hat Enterprise Linux
Ukulungelelaniswa kwemifanekiso yokufakela ngokukhawuleza iya kufumaneka kubasebenzisi ababhalisiweyo be-Portal yoMthengi we-Red Hat (ungasebenzisa kwakhona imifanekiso ye-CentOS Stream 9 iso ukuvavanya ukusebenza).
Ukukhutshwa kwenzelwe i-x86_64, s390x (IBM System z), ppc64le, kunye ne-Aarch64 (ARM64) izakhiwo. Imithombo yeRed Hat Enterprise Linux 9 rpm packages ibekwe kwindawo yokugcina iCentOS Git.
