命令实例copy模块
** 拷贝/data01/yc_files/ansible_test/1/1.txt到yc机器的/data01/yc_files/ansible_test/2/目录下
ansible yc -m copy -a "src=\"/data01/yc_files/ansible_test/1/1.txt\" dest=\"/data01/yc_files/ansible_test/2/\""
注：root执行，新文件属主为root；yc执行，新文件属主为yc
切换身份
** 切换身份安装libselinux-python
1.配置ansible.cfg中的become_ask_pass=True
2.ansible all --become --become-user=root --become-method=sudo -v -a "yum -y install libselinux-python"
错误汇总
1.Aborting, target uses selinux but python bindings (libselinux-python) aren't installed!
安装libselinux-python，关闭selinux，重启系统
2.Failed to connect to the host via ssh: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).\r\n
