ansible之setup模块

关于ansible的setup，具体说明在http: //docs.ansible.com/ansible/setup_module.html
其实类似saltstack的grains静态信息收集，收集一些主机硬件信息或者以及其他如fqdn等等

db是我在hosts中定义的组名也可以是主机ip

setup的用法

[root@ansible ~]# ansible-doc -s setup
less 436
Copyright (C) 1984-2009 Mark Nudelman
less comes with NO WARRANTY, to the extent permitted by law.
For information about the terms of redistribution,
see the file named README in the less distribution.
Homepage: http://www.greenwoodsoftware.com/less - name: Gathers facts about remote hosts
action: setup
fact_path              # path used for local ansible facts (*.fact) - files in this dir will be run (if executable) and
their results be added to ansible_local facts if a file is not
executable it is read. File/results format can be json or ini-
format
filter                 # if supplied, only return facts that match this shell-style (fnmatch) wildcard.

使用setup获取ip地址以及主机名使用filter过滤等等

ip地址

[root@ansible ~]# ansible db -m setup -a 'filter=ansible_default_ipv4'
db | SUCCESS => {
"ansible_facts": {
"ansible_default_ipv4": {
"address": "192.168.33.137",
"alias": "eth0",
"broadcast": "192.168.33.255",
"gateway": "192.168.33.2",
"interface": "eth0",
"macaddress": "00:0c:29:14:cc:24",
"mtu": 1500,
"netmask": "255.255.255.0",
"network": "192.168.33.0",
"type": "ether"
}
},
"changed": false
}

获取内存信息。

[root@ansible ~]# ansible db -m setup -a 'filter=ansible_memory_mb'
db | SUCCESS => {
"ansible_facts": {
"ansible_memory_mb": {
"nocache": {
"free": 217,
"used": 265
},
"real": {
"free": 101,
"total": 482,
"used": 381
},
"swap": {
"cached": 0,
"free": 991,
"total": 991,
"used": 0
}
}
},
"changed": false
}

获取主机名。。
[root@ansible ~]# ansible db -m setup -a 'filter=ansible_nodename'
db | SUCCESS => {
"ansible_facts": {
"ansible_nodename": "db"
},
"changed": false
}

ansible的setup就到这吧。那个fact_path,其实就是在本地定义一些键值对，然后指定文件路径使用.
