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

Complete!

 

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。
