Скрипт для установки репозиториев с Nexus

Скрипт написан на баше. Перед использованием — необходимо ознакомиться с двумя «кейсами» (case), чтобы понимать, как тут все устроено.

Перед запуском, обязательно дайте скрипту права на запуск

[root@test-vm ~]# chmod +x repo.sh

Непосредственно запускаем скрипт

[root@test-vm ~]# ./repo.sh

Разберем начинку скрипта.

После запуска, у вас вылезет список с репозиториями, которые вы прописали в скрипте. Вам необходимо вписать число для продолжения.

#!/bin/bash
echo -n "1. CentOS 6
2. CentOS 7
3. Oracle Linux 5.11
4. Oracle Linux 7
5. Rocky Linux 9
6. RedHat 7
7. Ubuntu 22.04
8. CentOS 9 Stream
Select your Operation System: "
read OS

Далее, вас спросят, что необходимо сделать. Первое — непосредственно установить репозитории. Второе — вернуть все как было, в случае фейла. Ответ так же вписываете цифрами (1 или 2)

case $OS in
	1 | CentOS | Centos | centos | "CentOS 6" | CENTOS | "CENTOS 6")

		echo "CentOS 6
		";
		echo -n "1. Install new repository
2. Revert previous settings back
Select an action: ";
		read ACTION

При выборе первого варианта, скрипт на всякий случай пойдет зачищать то, что могло быть создано им ранее, если человек повторно решил произвести установку, или обновить репозитории

case $ACTION in

			1 | Install )

				rm -f /etc/yum.repos.d/Centos_6.repo;

Создаем бекап, где будут лежать копии всех файлов с репозиториями

mkdir /etc/yum.repos.d/backup/;
cp /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/;

У оставшихся файлов, через команду sed меняем состояние enabled с 1 на 0, чтобы при работе с yum/apt они не были задействованы

REPOS=/etc/yum.repos.d/*.repo
for r in $REPOS
do
	echo "Editing $r";
	sed -i '/#/d' "$r";
	sed -i '/enabled=/d' "$r";
        sed -i '/\[*\]/a enabled=0' "$r";
done

Скачиваем наш файл с прописанными репами (источником может что угодно) и двигаем его в директорию ко всем репозиториям. Готово, репозитории установлены. Примеры .repo файлов приведу в конце.

echo "Installing Nexus repository for CentOS 6"
curl -X GET https://nexus.example.com/repository/reponame/Centos_6.repo -O -k;
mv Centos_6.repo /etc/yum.repos.d/;
echo "All repositories were disabled";
echo "New Nexus repository was installed";
;;

При выборе второго варианта, мы вернем нашу систему к прежнему состоянию, как до установки. Чистим все активные репозитории. Двигаем репозитории из бекапа в папку с активными репозиториями. И в конце зачищаем папку с бекапами.
