7 copy文件拷贝模块

常用参数

src　　　　#被复制到远程主机的本地文件。可以是绝对路径，也可以是相对路径。如果路径是一个目录，则会递归复制，用法类似于"rsync"
content    直接在批量的被管理端文件中追加内容
dest　　　　#必选项，将源文件复制到的远程主机的绝对路径
backup　　　#当文件内容发生改变后，在覆盖之前把源文件备份，备份文件包含时间信息
directory_mode　　　　#递归设定目录的权限，默认为系统默认权限
force　　　　#当目标主机包含该文件，但内容不同时，设为"yes"，表示强制覆盖；设为"no"，表示目标主机的目标位置不存在该文件才复制。默认为"yes"
others　　　　#所有的 file 模块中的选项可以在这里使用
group  本地文件推送到远端，指定文件属组
owner    本地文件推送到远端，指定文件属主
mode    本地文件推送到远端，指定文件权限信息

11 file模块设置文件属性

该模块主要用于设置文件的属性，比如创建文件、创建链接文件、删除文件等。

下面是一些常见的命令：

src        源文件路径
force　　#需要在两种情况下强制创建软链接，一种是源文件不存在，但之后会建立的情况下；另一种是目标软链接已存在，需要先取消之前的软链，然后创建新的软链，有两个选项：yes|no
group　　#定义文件/目录的属组。后面可以加上mode：定义文件/目录的权限
owner　　#定义文件/目录的属主。后面必须跟上path：定义文件/目录的路径
recurse　　#递归设置文件的属性，只对目录有效，后面跟上src：被链接的源文件路径，只应用于state=link的情况recurse=yes
dest　　#被链接到的路径，只应用于state=link的情况
state　　#状态，有以下选项：
directory：如果目录不存在，就创建目录
file：即使文件不存在，也不会被创建
link：创建软链接
hard：创建硬链接
touch：如果文件不存在，则会创建一个新的文件，如果文件或目录已存在，则更新其最后修改时间
absent：删除目录、文件或者取消链接文件

#1创建目录/data，属主666，属组666

[admin@pe-jira ~]$ ansible test -m file -a 'path=/data owner=666 group=666 recurse=yes state=directory'

    "secontext": "system_u:object_r:default_t:s0",
    "size": 6,
    "state": "directory",
    "uid": 666
}

#2创建文件/tmp/ansible-test，权限600

[admin@pe-jira ~]$ ansible test -m file -a 'path=/tmp/ansible-test state=touch mode=600'
