官方模块文档

command 执行命令（默认）
shell 执行命令
get_url 联网下载
yum 安装软件模块
copy 配置模块

command 执行命令（默认）

command模块执行的命令不能有管道，但shell模块可以

shell 执行命令

执行任何 shell 命令，可以使用管道，但对一些复杂的命令太不支持，比如 awk

[root@Ansible ~]# ansible hosts -m shell -a "ifconfig eth0|grep 'inet'"
localhost | CHANGED | rc=0 >>
        inet 192.168.1.1 netmask 255.255.255.0 broadcast 192.168.1.255

        inet6 fe80::1a2a:995:6f5a:ffe8 prefixlen 64 scopeid 0x20<link>
## 不太支持awk
[root@Ansible ~]# ansible hosts -m shell -a "df -h|awk '//$/{print $5}'"
localhost | CHANGED | rc=0 >>

/dev/mapper/centos-root 17G 3.1G 14G 18% /

get_url 联网下载

url ---文件在网络上的具体位置
dest ---下载到被控端的哪个目录下
checksum ---校验(md5 sha256)

## 生成yum缓存
[root@Ansible ~]# ansible web -m command -a "yum makecache"

yum 安装软件模块

name ---软件包名称
state ---指定使用yum的方法
- installed，present ---安装软件包
- removed，absent ---移除软件包
- latest ---安装最新软件包

copy 配置模块

src --- 推送数据的源文件信息
dest --- 推送数据的目标路径
backup --- 对原来的文件，会放到 /var/lib/docker/overlay2/ 目录下
content --- 直接批量在被管理端文件中添加内容
group --- 将本地文件推送到远端，指定文件属组信息
owner --- 将本地文件推送到远端，指定文件属主信息
mode --- 将本地文件推送到远端，指定文件权限信息
