当我尝试更改文件的权限时，为什么会从 Ansible 收到此错误？

Question

我在名为 tomcat 的角色中执行以下任务：

- name: copy tomcat file settings
  copy:
    src: "{{ item.src }}"
    dest: "{{ item.dest }}"
    owner: tomcat
    group: tomcat
    mode: "{{ item.mode }}"
  with_items:
  - { src: logrotate-tomcat7, dest: /etc/logrotate.d/tomcat7, mode: 0644 }
  - { src: keystore.pks, dest: /var/lib/tomcat7/webapps, mode: 0644  }
  - { src: jmxremote.access, dest: /etc/tomcat7, mode: 0644   }
  - { src: jmxremote.password, dest: /etc/tomcat7, mode: 0600 }

当我运行调用 tomcat 角色的 playbook 时，我看到以下输出：

TASK [devops-server : copy tomcat file settings] *********************************
changed: [10.71.10.11] => (item={u'dest': u'/etc/logrotate.d/tomcat7', u'src': u'logrotate-tomcat7', u'mode': 420})
changed: [10.71.10.11] => (item={u'dest': u'/var/lib/tomcat7/webapps', u'src': u'keystore.pks', u'mode': 420})
changed: [10.71.10.11] => (item={u'dest': u'/etc/tomcat7', u'src': u'jmxremote.access', u'mode': 420})
failed: [10.71.10.11] (item={u'dest': u'/etc/tomcat7', u'src': u'jmxremote.password', u'mode': 384}) => {"checksum": "2203ad1530a3bc06732043ba67d129b5364505ce", "details": "bad symbolic permission for mode: 384", "failed": true, "gid": 91, "group": "tomcat", "item": {"dest": "/etc/tomcat7", "mode": 384, "src": "jmxremote.password"}, "mode": "0644", "msg": "mode must be in octal or symbolic form", "owner": "tomcat", "path": "/etc/tomcat7/jmxremote.password", "size": 52, "state": "file", "uid": 91}
...ignoring

显然，模式 0600 在我的 EC2 实例的命令行上工作：

ec2-user@devops-01 ~]$ sudo chmod 0600 /etc/tomcat7/jmxremote.password
ec2-user@devops-01 ~]$ ls -l /etc/tomcat7/jmxremote.password
-rw------- 1 tomcat tomcat 52 Oct 28 16:18 /etc/tomcat7/jmxremote.password

那么什么给出呢？这是 Ansible 错误还是我遗漏了什么？

Answer 1

这显然是 Ansible 中的一个错误。对我来说，代码看起来不错。根据此GitHub Issue，octal可以通过将for设置mode为string. 像这样：0644 "0644"

所以我会尝试这个：

with_items:
 - { src: logrotate-tomcat7, dest: /etc/logrotate.d/tomcat7, mode: "0644" }
