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"
