简介: 本篇内容记录了yum安装ansible报错的解决方案。

文章参考:https://mirrors.tuna.tsinghua.edu.cn/help/epel/


前言:安装ansible出现如下错误:


Error: Package: python-paramiko-2.1.1-0.10.el7.noarch (epel)
           Requires: python-cryptography
Error: Package: ansible-2.9.21-1.el7.noarch (epel)
           Requires: python-six
Error: Package: ansible-2.9.21-1.el7.noarch (epel)
           Requires: PyYAML

           Requires: python-jinja2
Error: Package: ansible-2.9.21-1.el7.noarch (epel)
           Requires: python-setuptools
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest


一、报错信息:

二、如何解决


1、重装虚拟机


重装一台虚拟机,保证虚拟机可以上网,可以选择桥接模式网卡

2、修改yum源


建议先备份 /etc/yum.repos.d/ 内的文件(CentOS 7 及之前为 CentOS-Base.repo,CentOS 8 为CentOS-Linux-*.repo)


然后编辑 /etc/yum.repos.d/ 中的相应文件,在 mirrorlist= 开头行前面加 # 注释掉;并将 baseurl= 开头行取消注释(如果被注释的话),把该行内的域名(例如mirror.centos.org)替换为 mirrors.tuna.tsinghua.edu.cn。


以上步骤可以被下方的命令一步完成


sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
         -e 's|^#baseurl=http://mirror.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn|g' \
         -i.bak \
         /etc/yum.repos.d/CentOS-*.repo


注意其中的*通配符,如果只需要替换一些文件中的源,请自行增删。


注意,如果需要启用其中一些 repo,需要将其中的 enabled=0 改为 enabled=1。


最后,更新软件包缓存


sudo yum makecache


3、使用EPEL源


yum install epel-release
当前tuna已经在epel的官方镜像列表里,所以不需要其他配置,mirrorlist机制就能让你的服务器就近使用tuna的镜像。如果你想强制 你的服务器使用tuna的镜像,可以修改/etc/yum.repos.d/epel.repo,将mirrorlist和metalink开头的行注释掉。
接下来,取消注释这个文件里baseurl开头的行,并将其中的http://download.fedoraproject.org/pub替换成https://mirrors.tuna.tsinghua.edu.cn。
可以用如下命令自动替换:(来自 https://github.com/tuna/issues/issues/687)
sed -e 's!^metalink=!#metalink=!g' \
    -e 's!^#baseurl=!baseurl=!g' \
    -e 's!//download\.fedoraproject\.org/pub!//mirrors.tuna.tsinghua.edu.cn!g' \
    -e 's!http://mirrors\.tuna!https://mirrors.tuna!g' \
    -i /etc/yum.repos.d/epel.repo /etc/yum.repos.d/epel-testing.repo


4、安装ansible

ansible 2.9.21
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Nov 16 2020, 22:23:17) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]
