ansible 提示安装sshpass
之前用ansible一直用的root身份、机器之间又早早的做好了ssh信任、所以一直也没有出现什么问题。今天想想自己不能这么浪了，还是用回普通用户吧；然而马上就遇到了第一个问题，ansible提示安装sshpass这个软件包。
一、ansible提示安装sshpass这个软件包：
ansible workstudio -m ping
workstudio
| FAILED! => {"failed": true,"msg": "to use the 'ssh' connection type with passwords, you must install the sshpass program"
}
二、安装sshpass ：
yum -y install sshpass
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* epel: mirrors.ustc.edu.cn

三、注意sshpass这个包并不在系统光盘里面，它是epel这人源中包涵的包
四、测试ansible是否可用了：
ansible workstudio -m ping
workstudio
| SUCCESS => {"changed": false,"ping": "pong"
}
五、什么情况会出现要求安装sshpass:
如果在/etc/ansible/host 中配置的ssh登录用户使用的是密钥的认证是不会出现这个问题的；也就是说
1、在运行ansible的主机上要与被控机建立ssh信任。
2、在/etc/ansible/host文件中不要指ansible_ssh_pass这个变量，不然它就强制走密码认证了，而不是密钥。
