利用playbook配置不同版本系统的yum源

环境说明：

项目结构

[root@ansible yum]# tree
.
├── ansible.cfg
├── inventory
├── scripts
│   ├── yum_centos7.sh
│   └── yum_centos8.sh
└── yum.yml

1 directory, 5 files

准备工作

本次环境yum源是阿里云官方镜像网站

//映射主机名IP
[root@ansible ~]# vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.153.10 ansible
192.168.153.11 redhat8
192.168.153.12 centos8
192.168.153.13 centos7

//编写inventory清单
[root@ansible ~]# mv /etc/ansible/inventory yum/   //把清单文件移到yum目录下
[root@ansible yum]# vim inventory 

[redhat]
redhat8

[centos]
centos7
centos8

//修改清单的位置
[root@ansible ~]# mv /etc/ansible/ansible.cfg yum/    //把ansible.cfg移到yum目录下
[root@ansible yum]# vim ansible.cfg 

# some basic default values...

inventory      = ./inventory   //当前目录的inventory

//设置免密登录
[root@ansible yum]# ssh-keygen -t rsa     //生成密钥,直接回车
[root@ansible yum]# ssh-copy-id root@redhat8
[root@ansible yum]# ssh-copy-id root@centos8
[root@ansible yum]# ssh-copy-id root@centos7


//测试能否ping通
[root@ansible yum]# ansible all -m ping
redhat8 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}
centos8 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}
centos7 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}

配置yum脚本

//编写centos8的yum配置批处理
[root@ansible yum]# vim scripts/yum_centos8.sh 

#!/bin/bash
  
#centos8
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
sed -i 's|$releasever|8|' /etc/yum.repos.d/CentOS-Base.repo

#epel
yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm
sed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel*
sed -i 's|^metalink|#metalink|' /etc/yum.repos.d/epel*

#yum clean
yum clean all
yum makecache

//编写centos7的yum配置批处理
[root@ansible yum]# vim scripts/yum_centos7.sh 

#!/bin/bash
  
#centos7
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
sed -i 's|$releasever|7|' /etc/yum.repos.d/CentOS-Base.repo

#epel
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
sed -i 's|$releasever|7|' /etc/yum.repos.d/epel*

#yum clean
yum clean all
yum makecache

编写yum的playbook

[root@ansible yum]# vim yum.yml 

---
- name: yum
  hosts: all
  tasks:

    - name: centos8
      script: ./scripts/yum_centos8.sh
      when: >
        ( ansible_facts["distribution"] == "RedHat" and
          ansible_facts["distribution_major_version"] == "8" )
        or
        ( ansible_facts["distribution"] == "CentOS" and
          ansible_facts["distribution_major_version"] == "8" )

    - name: centos7
      script: ./scripts/yum_centos7.sh
      when: >
        ( ansible_facts["distribution"] == "RedHat" and
          ansible_facts["distribution_major_version"] == "7" )
        or
        ( ansible_facts["distribution"] == "CentOS" and
          ansible_facts["distribution_major_version"] == "7" )

执行剧本

[root@ansible yum]# ansible-playbook yum.yml

PLAY [yum] *************************************************************************

centos7                    : ok=2    changed=1    unreachable=0    failed=0    skipped=1    rescued=0    ignored=0   
redhat8                    : ok=2    changed=1    unreachable=0    failed=0    skipped=1    rescued=0    ignored=0
