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）

#打印192.168.98.201机器的所有信息
[root@manage01 ~]# ansible -m setup 192.168.98.201

#使用filter过滤输出
#打印192.168.98.201机器的CPU信息
[root@manage01 ~]# ansible -m setup 192.168.98.201 -a "filter='ansible_processor'"
192.168.98.201 | SUCCESS => {
    "ansible_facts": {
        "ansible_processor": [
            "0",
            "GenuineIntel",

    },

}
#打印192.168.98.201机器的内核信息
[root@manage01 ~]# ansible -m setup 192.168.98.201 -a "filter='ansible_kernel'"
192.168.98.201 | SUCCESS => {

#打印192.168.98.201机器的主机名

    },

}
#打印192.168.98.201机器的网卡信息
[root@manage01 ~]# ansible -m setup 192.168.98.201 -a "filter='ansible_ens*'"
192.168.98.201 | SUCCESS => {

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)。
