ansible-playbook配置不同系统yum源

准备工作

环境

主机	ip	系统
yc	192.168323.132	RHEL8
yc1	192.168.23.133	RHEL8
yc2	192.168.23.134	CentOS7

yum任务目录结构

[root@yc yum]# tree .
.
├── ansible.cfg
├── inventory
├── scripts
│   ├── centos7yum.sh
│   └── rhel8yum.sh
└── yum.yml

配置

关闭防火墙和selinux

[root@yc ~]# systemctl stop firewalld
[root@yc ~]# setenforce 0

映射

[root@yc yum]# vim /etc/hosts

192.168.23.133 yc1
192.168.23.134 yc2

复制ansible配置文件到yum目录下

[root@yc yum]# cp /etc/ansible/ansible.cfg .
[root@yc yum]# vim ansible.cfg 


[defaults]
...
# some basic default values...

inventory      = ./inventory  //设定清单在当前目录下

创建清单文件

[root@yc yum]# cat inventory 

[yum]
yc1
yc2

公钥

root@yc yum]# ssh-keygen -t rsa //直接回车
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 	
Enter passphrase (empty for no passphrase):

//复制公钥到受控机

[root@yc yum]# ssh-copy-id root@yc1
[root@yc yum]# ssh-copy-id root@yc2

查看清单
[root@yc yum]# ansible all --list-hosts
  hosts (2):
    yc1
    yc2

测试连接

[root@yc yum]# ansible yum -m ping
yc1 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
yc2 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}

编写yum配置剧本

[root@yc yum]# cat yum.yml 
---
- name: yum config
  hosts: yum
  gather_facts: yes 
  tasks:
#判断distribution是否为CentOS，主版本是否为7。二者均满足则配置centos7源，否则跳过
    - name: get centos7 yum
      script: ./scripts/centos7yum.sh
      when: 
        - ansible_facts["distribution"] == "CentOS"
        - ansible_facts["distribution_major_version"] == "7" 
        
#判断distribution是否为RedHat，主版本是否为8。二者均满足则配置rhel8源，否则跳过
    - name: get rhel8 yum
      script: ./scripts/rhel8yum.sh
      when: 
        - ansible_facts["distribution"] == "RedHat"
        - ansible_facts["distribution_major_version"] == "8"

编写yum配置脚本

//CentOS7 yum配置

[root@yc yum]# cat scripts/centos7yum.sh 
#! /bin/bash
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
yum clean all && yum makecache

//RHEL8 yum配置
[root@yc yum]# cat scripts/rhel8yum.sh 
#! /bin/bash
#yumconfig
curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo
#epel config
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*
#makecache
yum clean all && yum makecache
