Tres modi ad nucleum systematis CentOS computatri industrialis renovandum

Dum CentOS utitur, inevitabile est nucleum renovare, sed interdum propter problemata dependentiae compilationis codicis fontis, non omnia programmata recentissimam versionem nuclei sustinent, ergo sequentia tres modos ad nucleum renovandum introducent.

Nota:
De generibus nucleorum:
Litterae `ml` in `kernel-ml` sunt abbreviatio vocis Anglice `[mainline stable]`, et recentissima versio stabilis `mainline` in `elrepo-kernel` recensetur.
Litterae "lt" in kernel-lt sunt abbreviatio vocis "[long term support]" Anglice, et versio "long-term support" in "elrepo-kernel" recensetur.
Versionem nuclei inspice
uname -r

Index Rerum

• 1. institutio yum
• 2. RPM installatio
• 3. Installatio codicis fontis

1. institutio yum

1. Fontem repositorii importare
`rpm --import` (vel fortasse: `importatio rpm`) https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm
2. Sarcinas installabiles inspice.
`yum` `--enablerepo="elrepo-kernel"` index `--showduplicates` | `sort -r` | `grep`
kernel-ml.x86_64
3. Elige versionem ML vel LT ad instituendum.
Si nulla versio specificatur, recentissima versio per default installatur.
Versionem ML instala
`yum --enablerepo=elrepo-kernel install kernel-ml-devel kernel-ml -y`
Versionem LT instala, hanc pro omnibus K8S elige.
`yum --enablerepo=elrepo-kernel install kernel-lt-devel kernel-lt -y`
4. Ordinem incipiendi nuclei hodiernum inspice.
`awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg`
5. Elementum initiale implicitum mutare
`xxx` est numerus serialis, qui x-imum elementum in indice initiali ut elementum initiale specificat, et `x` a 0 numerare incipit.
grub2-set-default xxxx
Exempli gratia, si vis illud ita configurare ut cum nucleo 4.4 incipiat...
deinde directe "grub2-set-default 0" inscribe, et a versione 4.4 incipere poteris cum iterum incipies.
Sequentiam incipiendi nuclei inspice
`[root@localhost ~] awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg`
CentOS Linux (4.4.179-1.el7.elrepo.x86_64) 7 (Nucleus)
CentOS Linux (3.10.0-693.el7.x86_64) 7 (Nucleus)
CentOS Linux (0-rescue-6d4c599606814867814f1a8eec7bfd1e) 7 (Nucleus)
Numerum sequentiae initiationis constitue
`[root@localhost ~] grub2-set-default 0`
Reinitiatio
reiniciare
Versionem nuclei inspice
uname -r

2. RPM installatio

Versionem nuclei inspice
uname -r
1. Invenire versionem
Quia fons ELRepo est versio recentissima, versio vetus nuclei tantum manu depromi potest.
Invenire versionem historicam rpm nuclei:
http://mirrors.coreix.net/elrepo-archive-archive/kernel/el7/x86_64/RPMS/
2. Tria genera rpm tibi depromere necesse est.
wget
http://mirrors.coreix.net/elrepo-archive-archive/kernel/el7/x86_64/RPMS/kernel-lt
devel-4.4.215-1.el7.elrepo.x86_64.rpm
wget
http://mirrors.coreix.net/elrepo-archive-archive/kernel/el7/x86_64/RPMS/kernel-lt
capita-4.4.215-1.el7.elrepo.x86_64.rpm
wget
http://mirrors.coreix.net/elrepo-archive-archive/kernel/el7/x86_64/RPMS/kernel-lt-
4.4.215-1.el7.elrepo.x86_64.rpm
3. Nucleum instala
`rpm -ivh kernel-lt-4.4.215-1.el7.elrepo.x86_64.rpm`
`rpm -ivh kernel-lt-devel-4.4.215-1.el7.elrepo.x86_64.rpm`
vel
#Omnia uno clicculo instala
rpm -Uvh *.rpm
4. Versionem nuclei installatam confirma.
`[root@localhost ~]# rpm -qa | grep nucleus`
nuclei-capita-3.10.0-1160.15.2.el7.x86_64
kernel-devel-3.10.0-1160.49.1.el7.x86_64
nucleus-instrumentorum-bibliothecae-3.10.0-957.el7.x86_64
nucleus-3.10.0-957.el7.x86_64
kernel-ml-4.9.9-1.el7.elrepo.x86_64
kernel-lt-4.4.215-1.el7.elrepo.x86_64
instrumenta-nuclei-3.10.0-957.el7.x86_64
kernel-lt-devel-4.4.215-1.el7.elrepo.x86_64

5. Initium constituere
Ordinem initialem inspice
`[root@localhost ~]# awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg`
CentOS Linux (4.4.215-1.el7.elrepo.x86_64) 7 (Nucleus)
CentOS Linux (4.9.9-1.el7.elrepo.x86_64) 7 (Nucleus)
CentOS Linux (3.10.0-957.el7.x86_64) 7 (Nucleus)
CentOS Linux (0-rescue-b91f945269084aa98e8257311ee713c5) 7 (Nucleus)
Ordinem incipiendi constituere
`[root@localhost ~]# grub2-set-default 0`
Reincipe ut effectum habeat
[root@localhost ~]# reinitiare

3. Installatio codicis fontis

1. Fasciculum programmatum principalem instala.
`yum install -y gcc make git ctags ncurses-devel openssl-devel`
`yum install -y bison flex elfutils-libelf-devel bc`
2. Directorium compilationis nuclei crea.
Directorio "kernelbuild" sub "home" utere.
`mkdir ~/kernelbuild`
3. Codicem fontem nuclei accipe
Situs speculi Universitatis Tsinghuae:
https://mirror.tuna.tsinghua.edu.cn/kernel/v4.x/?C=M&O=D
Inscriptio fasciculi ad codicem fontis instituendum, quae alia ad deponendum est:
https://mirrors.edge.kernel.org/pub/linux/kernel/
linux-4.xx.xx.tar.xz
linux-4.xx.xx.tar.gz
Utraque forma accepta est; tar.xz maiorem compressionis rationem et minorem magnitudinem fasciculi habet.
Deprome in interrete: wget https://mirror.tuna.tsinghua.edu.cn/kernel/v4.x/linux-4.17.11.tar.xz
4. Codicem nuclei decomprime
Postquam id decompressum est, directorium fontis ingredere:
tar -xvJf linux-4.17.11.tar.xz
Ut arbor nuclei omnino pura sit, directorium nuclei intra et mandatum "make mrproper" exsequere:
CD Linux-4.17.11
Purgandum et aptum reddendum

5. Configuratio nuclei
Fasciculum configurationis nuclei hodierni exscribe.
config-3.10.0-862.el7.x86_64 est fasciculus configurationis nuclei ambitus mei praesentis, eum secundum condicionem actualem modifica.
`cp /boot/config-3.10.0-862.el7.x86_64 .config`
Configuratio provectior
y activum est, n inactivum, et m activum est cum opus est.
`menuconfig` facere: interfacies vetus `ncurses`, ab `nconfig` substituta.
`nconfig` nova: `ncurses` interfacies lineae mandati
6. Compila et instala
Nucleum compila
Si machinam quad-core habes, x potest esse 8.
facere -jx
Nucleum instala
Post compilationem nuclei, haec institue: Monitio: Ex hoc tempore, privilegiis administratoris principalis (root) opus est ad mandata exsequenda, alioquin errabit.
`modules_install` instituere
7. Initium constituere
Ordo initialis inspice
`[root@localhost ~]# awk -F\' '$1=="menuentry " {print $2}' /etc/grub2.cfg`
