Ansible-copy模块

一、copy模块(重点)

copy模块用于对文件的远程拷贝操作（如把本地的文件拷贝到远程的机器上)

https://docs.ansible.com/ansible/latest/modules/copy_module.html#copy-module

参数	说明
src	文件源路径
dest	目标路径
content	往目标文件输入内容
force	强制 yes or no
backup	是否备份有冲突的源文件[文件名相同，内容不同] yes or no
checksum	拷贝完整性校验，使用sha1sum生成校验码
owner	目标文件所有者
group	目标文件所属组
mode	目标文件权限

拷贝manage01机器/root/readme文件到group1组的机器。

1. 要求校验完整性，注意[checksum 是根据sha1算法做校验的]
2. 所有者、所属组都是sko
3. 权限0400

[root@manage01 ~]# sha1sum readme 
f8182e9ccdbe6efd13eb36a056a7db203fe66e40  readme
[root@manage01 ~]# ansible -m copy group1 -a "src=/root/readme dest=/opt checksum=f8182e9ccdbe6efd13eb36a056a7db203fe66e40 owner=sko group=sko mode=0400"

copy模块拷贝时要注意拷贝目录后面是否带"/"符号

/etc/yum.repos.d后面不带/符号，则表示把/etc/yum.repos.d整个目录拷贝到/tmp/目录下
[root@manage01 ~]# ansible group1 -m copy -a 'src=/etc/yum.repos.d dest=/tmp/'
/etc/yum.repos.d/后面带/符号，则表示把/etc/yum.repos.d/目录里的所有文件拷贝到/tmp/目录下
[root@manage01 ~]# ansible group1 -m copy -a 'src=/etc/yum.repos.d/ dest=/tmp/'

使用content参数直接往远程文件里写内容（会覆盖原内容）

[root@manage01 ~]# ansible -m file group1 -a "path=/tmp/zutuanxue_333 state=touch"
[root@manage01 ~]# ansible -m copy group1 -a "content='baism\nhello world\n' dest=/tmp/zutuanxue_333"
注意:ansible中-a后面的参数里也有引号时，记得要单引双引交叉使用，如果都为双引会出现问题

使用force参数控制是否强制覆盖

如果目标文件已经存在，则不覆盖
[root@manage01 ~]# ansible group1 -m copy -a "src=/tmp/zutuanxue_222 dest=/tmp/zutuanxue_333 force=no"
如果目标文件已经存在，则会强制覆盖
[root@manage01 ~]# ansible group1 -m copy -a "src=/tmp/zutuanxue_222 dest=/tmp/zutuanxue_333 force=yes"

使用backup参数控制是否备份文件

backup=yes表示如果拷贝的文件内容与原内容不一样，则会备份一份如果拷贝过来的文件本机存在，group1的机器上会将/tmp/333备份一份（备份文件命名加上时间），再远程拷贝新的文件为/tmp/333
[root@manage01 ~]# ansible group1 -m copy -a "src=/etc/fstab dest=/tmp/zutuanxue_333 backup=yes"
