配置主机yum源

场景：自己装了5台虚拟机，命令配置感觉有点小麻烦，干脆写个剧本，一次搞定，下次还能用。
注意：编写playbook时参考网址请到开源镜像站找到具体yum地址配置，然后替换就可以了。

1、创建以下目录中三个文件，目录自定义。

[student@master01 ~]# sudo ls -ll /opt/ansible/
total 8
-rw-r--r-- 1 root root 803 Dec 30 17:31 ansible.cfg
-rw-r--r-- 1 root root  50 Dec 29 21:53 inventory
drwxr-xr-x 2 root root  53 Dec 30 17:43 playbook 

[student@master01 ~]# sudo ls -ll /opt/ansible/playbook/
total 8
-rw-r--r-- 1 root root 579 Dec 29 22:07 create_user.yml
-rw-r--r-- 1 root root 756 Dec 30 17:43 k8s_yum_file.yml

2、编写ansible.cfg文件。

[student@master01 ~]# sudo cat /opt/ansible/ansible.cfg
# Since Ansible 2.12 (core):
......
[defaults]
inventory   = /opt/ansible/inventory
remote_user = student
ask_pass = false

[privilege_escalation]
become = true
become_method = sudo
become_user = root
become_ask_pass = false</
