知识点：使用copy模块，可以实现向目标机器进行远程copy的能力。
使用参数说明
| 参数 | 说明 |
|---|---|
| src | 被复制到远程主机的本地对象文件或者文件夹，可以是绝对路径，也可以是相对路径。 |
| dest | 被复制到远程主机的本地对象文件或者文件夹 |
| mode | 复制对象的设定权限 |
| backup | 在文件存在的时候可以选择覆盖之前，将源文件备份.设定值：yes/no 缺省为yes |
| force | 是否强制覆盖.设定值：yes/no 缺省为no |
| … | 其余请自行ansible-doc -s copy |
使用实例
使用ansible的copy的module将ttt.sh文件copy到远程的目标机上并命名为hello.sh
[root@host31 ~]# ansible host32 -m command -a /tmp/hello.shhost32 | FAILED | rc=2 >>[Errno 2] No such file or directory[root@host31 ~]# ansible host32 -m copy -a "src=/tmp/ttt.sh dest=/tmp/hello.sh mode=0750"host32 | SUCCESS => { "changed": true, "checksum": "098994f5d86562667b71ec90d13904eedf1be5f1", "dest": "/tmp/hello.sh", "gid": 0, "group": "root", "md5sum": "fcc7e6c36e7a19db4b69fab163e03a36", "mode": "0750", "owner": "root", "secontext": "unconfined_u:object_r:admin_home_t:s0", "size": 31, "src": "/root/.ansible/tmp/ansible-tmp-1469870735.2-12356407661121/source", "state": "file", "uid": 0}[root@host31 ~]# ansible host32 -m command -a /tmp/hello.shhost32 | SUCCESS | rc=0 >>hello world[root@host31 ~]#

force使用实例
default的情况下，force是yes的，所以什么都不写，文件存在的情况是会被覆盖的，如下所示。
[root@host31 ~]# ansible host32 -m raw -a "ls -l /tmp/hello.sh"host32 | SUCCESS | rc=0 >>-rwxr-x---. 1 root root 31 Jul 30 05:25 /tmp/hello.sh[root@host31 ~]# touch /tmp/ttt[root@host31 ~]# ll /tmp/ttt-rw-r--r--. 1 root root 0 Jul 30 05:39 /tmp/ttt[root@host31 ~]# ansible host32 -m copy -a "src=/tmp/ttt dest=/tmp/hello.sh"host32 | SUCCESS => { "changed": true, "checksum": "da39a3ee5e6b4b0d3255bfef95601890afd80709", "dest": "/tmp/hello.sh", "gid": 0, "group": "root", "md5sum": "d41d8cd98f00b204e9800998ecf8427e", "mode": "0750", "owner": "root", "secontext": "unconfined_u:object_r:admin_home_t:s0", "size": 0, "src": "/root/.ansible/tmp/ansible-tmp-1469871615.42-248549508847058/source", "state": "file", "uid": 0}[root@host31 ~]# ansible host32 -m raw -a "ls -l /tmp/hello.sh"host32 | SUCCESS | rc=0 >>-rwxr-x---. 1 root root 0 Jul 30 05:40 /tmp/hello.sh[root@host31 ~]#

明确写成force=no，此时将不会被覆盖。
[root@host31 ~]# ansible host32 -m shell -a "ls -l /tmp/hello.sh"host32 | SUCCESS | rc=0 >>-rwxr-x---. 1 root root 0 Jul 30 05:40 /tmp/hello.sh[root@host31 ~]# ll /tmp/ttt.sh-rwxr-x---. 1 root root 31 Jul 30 03:32 /tmp/ttt.sh[root@host31 ~]# ansible host32 -m copy -a "src=/tmp/ttt.sh dest=/tmp/hello.sh force=no"host32 | SUCCESS => { "changed": false, "dest": "/tmp/hello.sh", "src": "/tmp/ttt.sh"}[root@host31 ~]# ansible host32 -m shell -a "ls -l /tmp/hello.sh"host32 | SUCCESS | rc=0 >>-rwxr-x---. 1 root root 0 Jul 30 05:40 /tmp/hello.sh[root@host31 ~]#

backup使用实例
覆盖的动作作出之前，其会真正覆盖之前，会作出一个带时间戳的文件作为backup文件
[root@host31 ~]# ansible host32 -m copy -a "src=/tmp/ttt.sh dest=/tmp/hello.sh backup=yes"host32 | SUCCESS => { "backup_file": "/tmp/hello.sh.2016-07-30@05:59:50~", "changed": true, "checksum": "098994f5d86562667b71ec90d13904eedf1be5f1", "dest": "/tmp/hello.sh", "gid": 0, "group": "root", "md5sum": "fcc7e6c36e7a19db4b69fab163e03a36", "mode": "0750", "owner": "root", "secontext": "unconfined_u:object_r:admin_home_t:s0", "size": 31, "src": "/root/.ansible/tmp/ansible-tmp-1469872789.7-172371209052357/source", "state": "file", "uid": 0}[root@host31 ~]# ansible host32 -m shell -a "ls -l /tmp/hello*"host32 | SUCCESS | rc=0 >>-rwxr-x---. 1 root root 31 Jul 30 05:59 /tmp/hello.sh-rwxr-x---. 1 root root 0 Jul 30 05:40 /tmp/hello.sh.2016-07-30@05:59:50~ -〉此文件为backup文件-rw-r--r--. 1 root root 12 Jul 29 10:18 /tmp/helloworld[root@host31 ~]#
