在7.6版流变机上安装ansible的正确方法是什么？

Question

我们想要将ansible脱机安装在流变7.6机器上(参考- https://www.linuxschoolonline.com/how-to-install-ansible-offline-on-centos-or-redhat/ )

Ansible需要以下先决条件才能出现在系统中

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

所以我们用yum安装所有要求的rpm

我们可以看到它失败了

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

只要注意-我们是注册到红帽7.x储存库，我们不确定从哪里我们需要从哪里采取丢失的rpm，以及为什么流变回购不包括所有要求的rpm？

安装所有这些所需的rpm的建议是什么？

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

您正在尝试安装两个版本的python-keyczar，其中一个版本用于Mageia；这就是破坏事务的原因。

通常，要确定脱机安装所需的包，应从基线和跑开始。

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

它将把所有必需的包下载到指定的目录中。

在Ansible的例子中，您可以使用RHEL 7的安装说明：

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

这将将所有需求下载到/tmp/ansible-packages中。然后，您可以将包复制到其他系统(假设您在RHEL订阅中有适当数量的单元)并使用yum localinstall安装它们。
