ansblie模块总结
1,如何使用模块？
[root@localhost ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:iLerlu9akP5Hy63e6ubR7rJcB1AY/qQfJsBI19gqx10 root@localhost.localdomain
The key's randomart image is:
+---[RSA 2048]----+
| . .+.o. |
| . +..+.E |
| ..ooo.. |
| .o+o.= |
| +oo S = |
| . o ..= o |
| ..oo.o+ . |

模块:
command:远程执行命令
shell:远程执行shell命令，可支持$之类的变量
copy:从ansible服务器主控端复制文件到远程主机
Fetch:从远端主机复制到主控端，与copy相反
file:修改文件元数据或者属主(组)
unarchive:解包解压缩，包可在主控端也可在远程主机，以copy进行区分
archive:将主控端打包压缩，存储于被管理节点
hostname:设置远程主机主机名
cron:指定被控主机计划任务
yum:指定被控主机安装包文件，仅仅支持RHEL系列
service:管理被控主机服务
user与group:管理用户与用户组
