安裝Ansible
1.安裝EPEL源
yum install http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epelrelease-7-5.noarch.rpm
2.yum install -y ansible
或者用rpm方式安裝，需要六個(gè)包：
rpm -ivh python-keyczar-0.71c-2.el7.noarch.rpm
rpm -ivh sshpass-1.05-5.el7.x86_64.rpm
rpm -ivh python-httplib2
rpm -ivh python-jinja2
rpm -ivh python-paramiko
rpm -ivh ansible1.9-1.9.4-2.el7.noarch.rpm
驗(yàn)證：
ansible --version
常見問題：
