普通用户使用chown改变文件所属人和所属组权限不够问题

~/test> pwd

/home/was_wcm/test

~/test> ll

total 0

-rw------- 1 testuser testuser 0 Dec 19 17:46 a.txt

~/test> chown -R nginx:nginx a.txt 

chown: changing ownership of `a.txt': Operation not permitted

需要root用户权限才可以修改文件所属人和所属组

ansible host配置文件中添加“ansible_su_pass=Test@2016”字段

> vi /etc/ansible/hosts 

[slave]

192.168.1.100 ansible_ssh_user=testuser ansible_ssh_pass=123456 ansible_su_pass=Test@2016

使用普通用户修改失败

> ansible slave -m file -a "dest=/root/test.aaa mode=666 owner=nginx group=nginx"

192.168.1.100 | FAILED >> {

    "failed": true, 

    "msg": "file (/root/test.aaa) is absent, cannot continue", 

    "path": "/root/test.aaa", 

    "state": "absent"

}

使用root用户修改成功

> ansible slave -S -R root -m file -a "dest=/root/test.aaa mode=666 owner=nginx group=nginx" 

192.168.1.100 | success >> {

    "changed": true, 

    "gid": 1000, 

    "group": "nginx", 

    "mode": "0666", 

    "owner": "nginx", 

    "path": "/root/test.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa", 

    "size": 0, 

    "state": "file", 

    "uid": 1000

}
