Ansible学习笔记4-编程知识

file模块：

file模块用于对文件相关的操作（创建、删除、属性修改、软链接等）touch是创建。

[root@localhost ~]# ansible group1 -m file -a "path=/tmp/111 state=touch"
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/111","gid": 0,"group": "root","mode": "0644","owner": "root","size": 0,"state": "file","uid": 0
}
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/111","gid": 0,"group": "root","mode": "0644","owner": "root","size": 0,"state": "file","uid": 0
}

[root@localhost ~]# ansible group1 -m file -a "path=/tmp/111 state=touch owner=ftp group=daemon mode=777"
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/111","gid": 2,"group": "daemon","mode": "0777","owner": "ftp","size": 0,"state": "file","uid": 14
}
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/111","gid": 2,"group": "daemon","mode": "0777","owner": "ftp","size": 0,"state": "file","uid": 14
}

创建目录，并更改权限：directory：

[root@localhost ~]# ansible group1 -m file -a "path=/test/aaa/bbb state=directory mode=777"
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"gid": 0,"group": "root","mode": "0777","owner": "root","path": "/test/aaa/bbb","size": 6,"state": "directory","uid": 0
}
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"gid": 0,"group": "root","mode": "0777","owner": "root","path": "/test/aaa/bbb","size": 6,"state": "directory","uid": 0
}

[root@agent1 tmp]# cd /test/aaa/bbb
[root@agent1 bbb]# ll
total 0
[root@agent1 bbb]# pwd
/test/aaa/bbb

删除文件：absent

[root@localhost ~]# ansible group1 -m file -a "path=/tmp/112 state=absent"
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"path": "/tmp/112","state": "absent"
}
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"path": "/tmp/112","state": "absent"
}

absent：没有、缺席、缺乏的意思。

删除目录：

[root@localhost ~]# ansible group1 -m file -a "path=/test state=absent"
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"path": "/test","state": "absent"
}
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"path": "/test","state": "absent"
}

absent：目录将会递归被删除。文件和软链接将会unlinked。

创建软链接：

[root@localhost ~]# ansible group1 -m file -a "src=/tmp/111 path=/tmp/222 state=link"
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/222","gid": 0,"group": "root","mode": "0777","owner": "root","size": 8,"src": "/tmp/111","state": "link","uid": 0
}
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/222","gid": 0,"group": "root","mode": "0777","owner": "root","size": 8,"src": "/tmp/111","state": "link","uid": 0
}

我们看到软链接的文件的大小稍微大点。

硬链接：hard

[root@localhost ~]# ansible group1 -m file -a "src=/tmp/111 path=/tmp/555 state=hard"
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/555","gid": 2,"group": "daemon","mode": "0777","owner": "ftp","size": 0,"src": "/tmp/111","state": "hard","uid": 14
}
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"dest": "/tmp/555","gid": 2,"group": "daemon","mode": "0777","owner": "ftp","size": 0,"src": "/tmp/111","state": "hard","uid": 14
}

硬链接是看inode号。

group的组配置，要注意下是要存在的。

修改硬链接的属性：file ，如果是硬链接，就需要添加state=file，这个要注意的。

[root@localhost ~]# ansible group1 -m file -a "path=/tmp/555 state=file owner=ftp group=daemon mode=000"
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"gid": 2,"group": "daemon","mode": "0000","owner": "ftp","path": "/tmp/555","size": 0,"state": "hard","uid": 14
}
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"gid": 2,"group": "daemon","mode": "0000","owner": "ftp","path": "/tmp/555","size": 0,"state": "hard","uid": 14
}

修改文件的拥有者和属组：

[root@localhost ~]# ansible group1 -m file -a "path=/tmp/aaa owner=ftp group=daemon mode=000"
192.168.17.105 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"gid": 2,"group": "daemon","mode": "0000","owner": "ftp","path": "/tmp/aaa","size": 0,"state": "file","uid": 14
}
192.168.17.106 | CHANGED => {"ansible_facts": {"discovered_interpreter_python": "/usr/bin/python"},"changed": true,"gid": 2,"group": "daemon","mode": "0000","owner": "ftp","path": "/tmp/aaa","size": 0,"state": "file","uid": 14
}
