在 rhel 機器 7.6 版本上安裝 ansible 的正確方法是什麼

我們想ansible在 rhel 7.6 機器上安裝離線（參考 - https://www.linuxschoolonline.com/how-to-install-ansible-offline-on-centos-or-redhat/）

Ansible 需要在系統上存在以下先決條件

python-crypto
python-httplib
python-jinja2
python-keyczar
sshpass

所以我們通過 yum 安裝所有請求的 rpm

我們可以看到它失敗了

Error: Package: python-keyczar-0.71c-8.mga7.noarch (/python-keyczar-0.71c-8.mga7.noarch)
          Requires: python2.7dist(pyasn1)
Error: Package: python-keyczar-0.71c-8.mga7.noarch (/python-keyczar-0.71c-8.mga7.noarch)
          Requires: python2.7dist(pycrypto) > 2.0

請注意 - 我們已註冊到 redhat 7.x 儲存庫，我們不確定需要從哪裡獲取失去的 rpm，以及為什麼 rhel repo 不包含所有必需的 rpm？

安裝所有這些必需的 rpm 的建議是什麼？

yum localinstall -y  python-keyczar-0.71c-2.el7.noarch.rpm  sshpass-1.06-2.el7.x86_64.rpm python2-crypto-2.6.1-15.el7.x86_64.rpm python-httplib2-0.9.2-1.el7.noarch.rpm python-jinja2-2.7.2-4.el7.noarch.rpm python-keyczar-0.71c-8.mga7.noarch.rpm

您正在嘗試安裝兩個版本的python-keyczar，其中一個用於 Mageia；這就是破壞交易的原因。

一般來說，要弄清楚離線安裝需要哪些包，您應該從基線開始，然後執行

sudo yum install --downloadonly --downloaddir=<directory> <package>

這會將所有必需的包下載到指定目錄。

在 Ansible 的情況下，您將按照RHEL 7 的安裝說明進行操作：

sudo subscription-manager repos --enable rhel-7-server-ansible-2.9-rpms
mkdir /tmp/ansible-packages
sudo yum install --downloadonly --downloaddir=/tmp/ansible-packages ansible

這會將所有要求下載到/tmp/ansible-packages. 然後，您可以將軟體包複製到其他系統（假設您的 RHEL 訂閱中有適當數量的單元）並使用yum localinstall.
