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 pingworkstudio | 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 sshpassLoaded plugins: fastestmirror, langpacksLoading mirror speeds from cached hostfile * epel: mirrors.ustc.edu.cnResolving Dependencies--> Running transaction check---> Package sshpass.x86_64 0:1.06-1.el7 will be installed--> Finished Dependency ResolutionDependencies Resolved============================================================================================================================== Package                       Arch                         Version                          Repository                  Size==============================================================================================================================Installing: sshpass                       x86_64                       1.06-1.el7                       epel                        21 kTransaction Summary==============================================================================================================================Install  1 PackageTotal download size: 21 kInstalled size: 38 kDownloading packages:warning: /var/cache/yum/x86_64/7/epel/packages/sshpass-1.06-1.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID 352c64e5: NOKEYPublic key for sshpass-1.06-1.el7.x86_64.rpm is not installedsshpass-1.06-1.el7.x86_64.rpm                                                                          |  21 kB  00:00:00     Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7Importing GPG key 0x352C64E5: Userid     : "Fedora EPEL (7)

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 pingworkstudio | 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。
