[8] DNF/Yum – lokalny obraz repozytoriów

Skonfiguruj lokalny serwer repozytorium DNF/Yum, aby szybciej aktualizować pakiety dla serwerów lokalnych.

W tym przykładzie skonfiguruj repozytoria lustrzane [BaseOS], [AppStream], [Extras], które są domyślnie włączone w CentOS Stream 8.

[1] Zainstaluj i uruchom serwer httpd Apache, patrz tutaj.

[2] Zainstaluj inne wymagane pakiety.

[root@vlsr05 ~]# dnf install yum-utils

[3] Utwórz katalogi dla repozytorium i skopiuj dane z oficjalnego repozytorium CentOS Stream.

[root@vlsr05 ~]# mkdir -p /var/www/repos/centos-stream/8/x86_64/os
[root@vlsr05 ~]# chmod -R 755 /var/www/repos

# skopiuj z oficjalnego repozytorium
[root@vlsr05 ~]# reposync -p /var/www/repos/centos-stream/8/x86_64/os/ --repo=baseos --download-metadata
[root@vlsr05 ~]# reposync -p /var/www/repos/centos-stream/8/x86_64/os/ --repo=apownload-metadata
[root@vlsr05 ~]# reposync -p /var/www/repos/centos-stream/8/x86_64/os/ --repo=extras --download-metadata

[4] Dodaj zadanie kopiowania do codziennych zadań.

[root@vlsr05 ~]# mcedit /etc/cron.daily/update-repo
# stwórz nowy
#!/bin/bash
VER='8'
ARCH='x86_64'
REPOS=(baseos appstream extras)
for REPO in ${REPOS[@]}
do
    reposync -p /var/www/repos/centos-stream/${VER}/${ARCH}/os/ --repo=${REPO} --download-metadata --newest-only
done

[root@vlsr05 ~]# chmod 755 /etc/cron.daily/update-repo

[5] Skonfiguruj serwer httpd Apache, aby zapewnić repozytorium dla innych hostów/klientów w sieci lokalnej.

[root@vlsr05 ~]# mcedit /etc/httpd/conf.d/repos.conf
# stwórz nowy
Alias /repos /var/www/repos
<directory /var/www/repos>
    Options +Indexes
    Require all granted
</directory>

[6] Jeśli Firewalld jest uruchomiony, zezwól na usługę HTTP.

[root@vlsr05 ~]# firewall-cmd --add-service=http --permanent
[root@vlsr05 ~]# firewall-cmd –reload

[7] Na hostach klienta zmień ustawienia DNF/Yum, aby odnieść się do lokalnego hosta lustrzanego z repozytoriami DNF/Yum.

[root@vlsr04 ~]# mcedit /etc/yum.repos.d/CentOS-Stream-BaseOS.repo
