ansible常用模块之yum
yum模块用于在指定节点机器上通过yum管理软件，其支持的参数主要有两个
state常用的值：
- latest：安装软件
- installed：安装软件
- present：安装软件
- removed：卸载软件
- absent：卸载软件
若想使用yum来管理软件，请确保受控机上的yum源无异常。
//在受控机上查询看httpd软件是否安装
[root@localhost ~]# rpm -qa|grep httpd
[root@localhost ~]#
//在ansible主机上使用yum模块在受控机上安装httpd
[root@ansible ~]# ansible 192.168.118.130 -m yum -a 'name=httpd state=present'
