一、setup 模块

setup 模块用于收集远程主机的基本信息（如操作系统类型, 主机名,ip,cpu 信息, 内存信息等）

其它常见的过滤条件
ansible_all_ipv4_addresses：显示 ipv4 的信息。ansible_devices：显示磁盘设备信息。ansible_distribution_major_version：显示是系统主版本。ansible_distribution_version：仅显示系统版本。ansible_machine：显示系统类型，例：32位，还是 64 位。ansible_lvm：显示 lvm 相关信息。ansible_memtotal_mb：显示系统总内存。ansible_memfree_mb：显示可用系统内存。ansible_memory_mb：详细显示内存情况。ansible_swaptotal_mb：显示总的 swap 内存。ansible_swapfree_mb：显示 swap 内存的可用内存。ansible_mounts：显示系统磁盘挂载情况。ansible_processor：显示 cpu 个数(具体显示每个 cpu 的型号)。ansible_processor_vcpus：显示 cpu 个数(只显示总的个数)。
