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):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:8uEqvn1A0Ef392b9TJsW818mjZHhD5zHLHNhs1A0dOs root@ansible
The key's randomart image is:
+---[RSA 3072]----+

//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
