ansible(6)--ansible的copy和fetch模块

1. copy模块

功能：从 ansible 服务端主控端复制文件到远程主机；

copy模块的主要参数如下：

参数 说明
src 复制的源文件路径，若源文件为目录，默认进行递归复制，如果路劲以“/”结尾，仅会复制目录下的内容，该目录本身不会复制，如果路径不带“/”，目录本身和目录下的内容会一并复制过去。
dest 目标绝对路径，如果源是文件夹，目标也必须是文件夹，不存在将创建
backup 如果目标主机已经有源文件，会事先备份，防止覆盖
mode 文件复制到远程并设定权限，默认file=644，directory=755
owner 文件复制到远程并设定属主，默认为root
group 文件复制到远程并设定属组，默认为root
content 将目标文件的内容，指定为content所带的字符串

  • 示例一：把/data/nginx/html/web01/index.html复制到被控主机/tmp目录下，属主属组为nginx，权限为644：

    [root@xuzhichao ~]# ansible NginxWebs -m copy -a "src=/data/nginx/html/web01/index.html dest=/tmp owner=nginx group=nginx mode=644"
192.168.20.22 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "changed": true, 
    "checksum": "b346efabe3aa64027fd74cceabfe9548989cea00", 
    "dest": "/tmp/index.html",

    "mode": "0644", 
    "owner": "nginx", 
    "size": 7, 
    "src": "/root/.ansible/tmp/ansible-tmp-1627787786.2-6672-67801950378810/source", 
    "state": "file", 
    "uid": 887
}
192.168.20.23 | CHANGED => {

    },

    "uid": 887
}

[root@nginx03 ~]# ll /tmp/index.html 
-rw-r--r-- 1 nginx nginx 7 Aug  1 11:16 /tmp/index.html

  • 示例二：再次复制上例文件，并对原文件备份：

    [root@xuzhichao ~]# ansible NginxWebs -m copy -a "src=/data/nginx/html/web01/index.html dest=/tmp owner=nginx group=nginx mode=644 backup=yes"
192.168.20.23 | CHANGED => {

    }, 
    "backup_file": "/tmp/index.html.6043.2021-08-01@11:20:39~", 
    "changed": true, 
    "checksum": "f8834b5232582035f785a3dc77a6303e339d1157",

    "state": "file", 
    "uid": 887
}
192.168.20.22 | CHANGED => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    }, 
    "backup_file": "/tmp/index.html.7789.2021-08-01@11:20:39~",

    "gid": 887, 
    "group": "nginx", 
    "md5sum": "747df44881df1860170c66321f38ce4c",

    "state": "file", 
    "uid": 887
}

[root@nginx03 ~]# ll /tmp/index.html*
-rw-r--r-- 1 nginx nginx 10 Aug  1 11:20 /tmp/index.html
-rw-r--r-- 1 nginx nginx  7 Aug  1 11:16 /tmp/index.html.6043.2021-08-01@11:20:39~   <==备份的原文件

  • 往远程的主机文件中写入内容，如果文件不存在则创建：

    [root@xuzhichao ~]# ansible NginxWebs -m copy -a "content="Http_Server\n" dest=/var/www/html/index.html"
192.168.20.23 | CHANGED => {

}

[root@nginx03 ~]# cat /var/www/html/index.html 
Http_Server

  • 示例四：复制目录到目标主机：

    [root@xuzhichao ~]# ansible NginxWebs -m copy -a "src=/root/test dest=/root"

    }, 
    "changed": true,

    "state": "file", 
    "uid": 0
}

[root@nginx03 ~]# ll /root/test/
total 4
-rw-r--r-- 1 root root 3258 Aug  1 11:26 nginx.conf

2. fetch模块

作用：从客户端取文件（只能是文件,不支持目录）至服务器端的目录里，与copy相反，如果一定要拉取目录，可以先将目录tar，再拉取。

主要参数如下：

参数 说明
src 复制的源文件路径，源文件只能是文件
dest 目标绝对路径

  • 示例一：把被控主机的/etc/nginx/nginx/conf配置文件拷贝到本机的/root/nginx目录下：

    [root@xuzhichao ~]# ansible NginxWebs -m fetch -a 'src=/etc/nginx/nginx.conf dest=/root/nginx'

    "remote_checksum": "b9671ff7a350dbf83543ec585e776500d45dccf0", 
    "remote_md5sum": null
}

#注意：把远程主机文件拷贝到本机时，会为每个远程主机建立一个文件夹，名称就是该远程主机的ip地址，然后把文件分别放到对应主机的目录下；
[root@xuzhichao ~]# tree /root/nginx

6 directories, 2 files

  • 示例二：拷贝远程主机的目录到本机

    #1.首先需要把远程主机的目录打包，默认打包到远程主机的家目录下（/root）
[root@xuzhichao ~]# ansible NginxWebs -m shell -a 'tar jcf log.tar.bzip2 /var/log/nginx/access*'
[WARNING]: Consider using the unarchive module rather than running 'tar'.  If you need to use command because unarchive is insufficient you can add 'warn:
false' to this command task or set 'command_warnings=False' in ansible.cfg to get rid of this message.
192.168.20.23 | CHANGED | rc=0 >>
tar: Removing leading `/' from member names
192.168.20.22 | CHANGED | rc=0 >>

#2.把打包文件取回本机：
[root@xuzhichao ~]# ansible NginxWebs -m fetch -a 'src=/root/log.tar.bzip2 dest=/root/nginx'
