1.在执行k8s 初始化的时候老是报错：data could not be sent to remote host

root@master1:/etc/kubeasz# ./ezctl setup k8s-01 01
ansible-playbook -i clusters/k8s-01/hosts -e @clusters/k8s-01/config.yml  playbooks/01.prepare.yml
2022-04-17 18:05:37 INFO cluster:k8s-01 setup step:01 begins in 5s, press any key to abort:

2.分析

2.1 在ansible 本机的hosts 文件里面测试

root@master1:~# vim /etc/ansible/hosts
[master2]
10.0.0.161

2.2 执行时发现也报错

报错： /usr/bin/python: not found

root@master1:~# ansible master2 -m shell -a 'ls /root/'
10.0.0.161 | FAILED! => {
    "changed": false, 
    "module_stderr": "Shared connection to 10.0.0.161 closed.\r\n", 
    "module_stdout": "/bin/sh: 1: /usr/bin/python: not found\r\n", 
    "msg": "MODULE FAILURE", 
    "rc": 127
}

2.3 于是我安装了 python 并执行了软链接

root@master1:~# ln -s /usr/bin/python2.7 /usr/bin/python 

3.然后就完成了
