002、debug调试模块
本文最后更新于 257 天前,其中的信息可能已经过时,如有错误请发送邮件到wuxianglongblog@163.com

debug调试模块

1. 概要

2. 模块参数

参数 可选值 默认值 说明
msg "Hello world!" string,打印的自定义消息。 如果省略,则输出默认消息。
var string,要调试的变量名。与msg选项互斥。请注意,此选项已在Jinja2上下文中运行,并且具有隐式{{}}包装,因此,除非您要查找双重插值,否则不应使用Jinja2定界符。
verbosity 0 integer,控制调试运行的数字,如果设置为3,则仅在-vvv或更高版本时运行调试。

3. 运行剧本

我们参照官方示例,编写剧本并运行剧本。

# 查看剧本文件
[ansible@master ~]$ cat debug.yml 
- hosts: node1
  vars:
    password_used: securedockerpassword
  tasks:
    # Example that prints the loopback address and gateway for each host
    - name: prints the loopback address and gateway
      debug:
        msg: System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}

    - name: print message
      debug:
        msg: System {{ inventory_hostname }} has gateway {{ ansible_default_ipv4.gateway }}
      when: ansible_default_ipv4.gateway is defined

    # Example that prints return information from the previous task
    - name: get the return information
      command:
        cmd: hostname -I
      register: result

    - name: print the result
      debug:
        var: result
        verbosity: 2

    - name: Display all variables/facts known for a host
      debug:
        var: hostvars[inventory_hostname]
        verbosity: 4

    # Example that prints two lines of messages, but only if there is an environment value set
    - debug:
        msg:
        - "Provisioning based on YOUR_KEY which is: {{ lookup('env', 'YOUR_KEY') }}"
        - "These servers were built using the password of '{{ password_used }}'. Please retain this for later use."

语法检查:

# 检查剧本规范,提示有一个异常,看不懂如何修改
[ansible@master ~]$ ansible-lint debug.yml 
[301] Commands should not change things if nothing needs doing
debug.yml:16
Task/Handler: get the return information

[ansible@master ~]$ 

在ansible-lint源码网站的issue中查到到了类似的问题https://github.com/ansible/ansible-lint/issues/165Handlers should be allows to run shell/command entries without when,大意是当运行shellcommand命令时,可以不需要带when条件判断语句。ansible-lint会去检查有没有带whenchanged_whenfailed_when之类的参数,参考Ansible changed_when and failed_when examples,上面有很多使用whenchanged_whenfailed_when条件语句的示例。我们复制几个例子放在下面,你可以看看。

  • 只有当操作系统是Debian时才会执行任务
tasks:
  - name: "shut down Debian flavored systems"
    command: /sbin/shutdown -t now
    when: ansible_os_family == "Debian"
  • 只有当httpd服务没有安装时才会执行任务
--- 
- hosts: web
  tasks:
  - name: "Determine if the HTTPD is installed"
    register: validatehttpd
    shell: httpd

  - name: Ensure Apache is at the Latest version
    become: yes
    become_user: root
    yum:
      name: httpd
      state: latest
    when: 'not found' in validatehttpd.stdout
  • 只有当系统是CentOS6或Debian7时才进行关机
---
- hosts: all
  tasks:
  - name: "shut down CentOS 6 and Debian 7 systems"
    command: /sbin/shutdown -t now
    when: (ansible_distribution == "CentOS" and ansible_distribution_major_version == "6") or
          (ansible_distribution == "Debian" and ansible_distribution_major_version == "7")
  • 只有当httpd服务没有启动时才执行任务
--- 
- hosts: web
  tasks:
  - name: "Start the Apache HTTPD Server"
    become: true
    become_user: root
    register: starthttpdout
    shell: "httpd -k start"
    changed_when: "'already running' not in starthttpdout.stdout"

  - debug:
      msg: "{{starthttpdout.stdout}}"
  • 只有当某些包没有安装时才执行任务
- name: Install dependencies via Composer.
  command: "/usr/local/bin/composer global require phpunit/phpunit --prefer-dist"
  register: composer
  changed_when: "'Nothing to install or update' not in composer.stdout"
  • 当服务器不满足硬件要求时任务失败
---
- hosts: app
  tasks:
  - name: Making sure the /tmp has more than 1gb
    shell: "df -h /tmp|grep -v Filesystem|awk '{print $4}'|cut -d G -f1"
    register: tmpspace
    failed_when: "tmpspace.stdout|float < 1"

  - name: Making sure the /opt has more than 4gb
    shell: "df -h /opt|grep -v Filesystem|awk '{print $4}'|cut -d G -f1"
    register: tmpspace
    failed_when: "tmpspace.stdout|float < 4"

  - name: Making sure the Physical Memory more than 2gb
    shell: "cat /proc/meminfo|grep -i memtotal|awk '{print $2/1024/1024}'"
    register: memory
    failed_when: "memory.stdout|float < 2"

我们在剧本文件中加个when条件试一下!

[ansible@master ~]$ cat debug.yml 
- hosts: node1
  vars:
    password_used: securedockerpassword
  tasks:
    # Example that prints the loopback address and gateway for each host
    - name: prints the loopback address and gateway
      debug:
        msg: System {{ inventory_hostname }} has uuid {{ ansible_product_uuid }}

    - name: print message
      debug:
        msg: System {{ inventory_hostname }} has gateway {{ ansible_default_ipv4.gateway }}
      when: ansible_default_ipv4.gateway is defined

    # Example that prints return information from the previous task
    - name: get the return information
      command:
        cmd: hostname -I
      when: true
      register: result

    - name: print the result
      debug:
        var: result
        verbosity: 2

    - name: Display all variables/facts known for a host
      debug:
        var: hostvars[inventory_hostname]
        verbosity: 4

    # Example that prints two lines of messages, but only if there is an environment value set
    - debug:
        msg:
        - "Provisioning based on YOUR_KEY which is: {{ lookup('env', 'YOUR_KEY') }}"
        - "These servers were built using the password of '{{ password_used }}'. Please retain this for later use."

[ansible@master ~]$ ansible-lint debug.yml 
[ansible@master ~]$ 

此时可以看到,使用ansible-lint进行规范检查,没有报任何异常,说明剧本编写正常!

注意,剧本文件中使用了

{{ lookup('env', 'YOUR_KEY') }}

这个是lookup模块中读取Ansible服务器(不是远程主机)的环境变量。我们在Ansible master上面设置一下这个变量:

[ansible@master ~]$ tail -n 1 ~/.bashrc
export YOUR_KEY='myansiblekeyinmaster..432fdsfdsafdsadb'

注意,此处在~/.bashrc中添加变量后,需要重新加载一下环境:

[ansible@master ~]$ source ~/.bashrc
[ansible@master ~]$ echo $YOUR_KEY 
myansiblekeyinmaster..432fdsfdsafdsadb

我们再来执行一下剧本:

# 剧本文件语法检查
[ansible@master ~]$ ansible-playbook --syntax-check debug.yml 

playbook: debug.yml

# 执行剧本,查看详情
[ansible@master ~]$ ansible-playbook debug.yml -v
Using /etc/ansible/ansible.cfg as config file

[ansible@master ~]$ 

可以看到,print the resultDisplay all variables/facts known for a host两个任务并没有执行,忽略的任务数为 skipped=2,原因是Verbosity threshold not met.,即未达到详细程度阈值。我们重新运行时,将命令行中的-v改成-vv再运行一次:

[ansible@master ~]$ 

此时可以看到,仅一个任务skipped=1被忽略掉,Display all variables/facts known for a host被忽略,原因是Verbosity threshold not met.,即未达到详细程度阈值。

再查看更详细的日志:

    }
}

    "msg": [
        "Provisioning based on YOUR_KEY which is: myansiblekeyinmaster..432fdsfdsafdsadb", 
        "These servers were built using the password of 'securedockerpassword'. Please retain this for later use."
    ]
}

可以看到,此时所有任务都执行了,并且没有忽略任何任务。

4. register注册变量

我们在剧本中也可以使用register关键字来注册变量,然后在后续的任务中使用变量。

以下示例是将hostname的输出注册到info变量中,然后在后一个任务中打印变量的信息:

剧本文件register.yml的内容如下:

---
- hosts: node1
  tasks:
    - name: register variable
      ansible.builtin.command:
        cmd: hostname
      register: info

    - name: display variable
      ansible.builtin.debug:
        msg: The variable is {{ info['stdout'] }}

执行剧本:

[ansible@master ansible_playbooks]$ ansible-lint register.yml
[ansible@master ansible_playbooks]$ ansible-playbook register.yml -v
Using /etc/ansible/ansible.cfg as config file

PLAY [node1] ***********************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************
ok: [node1]

TASK [register variable] ***********************************************************************************************
changed: [node1] => {"changed": true, "cmd": ["hostname"], "delta": "0:00:00.010386", "end": "2023-07-22 19:34:55.456539", "rc": 0, "start": "2023-07-22 19:34:55.446153", "stderr": "", "stderr_lines": [], "stdout": "node1", "stdout_lines": ["node1"]}

TASK [display variable] ************************************************************************************************
ok: [node1] => {
    "msg": "The variable is node1"
}

PLAY RECAP *************************************************************************************************************
node1                      : ok=3    changed=1    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

[ansible@master ansible_playbooks]$

效果图如下:

Snipaste_2023-07-22_19-38-04

5. 在剧本中使用vars定义变量

也可以在剧本中通过vars关键字来定义变量。

以下示例variable.yml中用vars关键字定义了两个变量:

---
- hosts: node1
  # 定义变量
  vars:
    - service_name: Nginx
    - listen_port: 80

  tasks:
    - name: display variable from variable list
      ansible.builtin.debug:
        msg: The service name is {{ service_name }} and the listen port is {{ listen_port }}

执行剧本文件:

[ansible@master ansible_playbooks]$ ansible-lint variable.yml
[ansible@master ansible_playbooks]$ ansible-playbook variable.yml -v
Using /etc/ansible/ansible.cfg as config file

PLAY [node1] ***********************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************
ok: [node1]

TASK [display variable from variable list] *****************************************************************************
ok: [node1] => {
    "msg": "The service name is Nginx and the listen port is 80"
}

PLAY RECAP *************************************************************************************************************
node1                      : ok=2    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

[ansible@master ansible_playbooks]$

效果图如下:

Snipaste_2023-07-22_22-24-18

可以看到,成功获取到变量service_namelisten_port的值了。

6. 在剧本中使用vars_files指定变量文件

我们也可以将变量写到文件中,然后在剧本中使用vars_files关键字来指定变量文件,请看以下示例。

首先,创建vars文件夹,并在vars文件夹下创建两个变量定义文件:

# 创建存放变量文件的文件夹
[ansible@master ansible_playbooks]$ mkdir vars

# 查看变量定义文件内容:
[ansible@master ansible_playbooks]$ cat vars/vars_file1.yaml
---
  - service_name1: Nginx
  - service_name2: Redis

[ansible@master ansible_playbooks]$ cat vars/vars_file2.yaml
---
  - listen_port1: 80
  - listen_port2: 6379

[ansible@master ansible_playbooks]$

编写剧本文件vars_files.yml:

---
- hosts: node1
  # 定义变量文件
  vars_files:
    - vars/vars_file1.yaml
    - vars/vars_file2.yaml

  tasks:
    - name: display variable from variable list
      ansible.builtin.debug:
        msg: |
          The first service name is {{ service_name1 }} and the listen port is {{ listen_port1 }}.
          The second service name is {{ service_name2 }} and the listen port is {{ listen_port2 }}.

然后执行vars_files.yml剧本:

[ansible@master ansible_playbooks]$ ansible-lint vars_files.yml
[ansible@master ansible_playbooks]$ ansible-playbook vars_files.yml -v
Using /etc/ansible/ansible.cfg as config file

PLAY [node1] ***********************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************
ok: [node1]

TASK [display variable from variable list] *****************************************************************************
ok: [node1] => {
    "msg": "The first service name is Nginx and the listen port is 80.\nThe second service name is Redis and the listen port is 6379.\n"
}

PLAY RECAP *************************************************************************************************************
node1                      : ok=2    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

[ansible@master ansible_playbooks]$

效果图如下:

Snipaste_2023-07-23_22-41-57

可以看到,正常从两个变量文件中获取到了服务的名称和服务的监听端口信息。

7. 使用vars_prompt通过交互模式获取变量

  • Ansible还支持在运行剧本的时候,通过交互式的方式给定义的参数传入变量值,只需要在剧本中定义vars_prompt的变量名和交互式提示内容即可。
  • Ansible也可以对输入的变量值进行加密处理,如采用SHA512和MD5算法加密。

以下编写一个vars_prompt.yml的剧本,用于在交互模式下读取服务的名称和监听端口:

---
- hosts: node1
  # 定义交互式获取变量
  vars_prompt:
    - name: service_name
      prompt: please input the service name
      # 非私有时,会显示输入的变量值
      private: no
    - name: listen_port
      prompt: please input the service listen port
      # 设置默认端口号,也可以不设置
      default: 6666
      # 私有时。不会显示输入的变量值,对于密码输入的话,可以避免密码泄漏
      private: yes

  tasks:
    - name: display variable from variable list
      ansible.builtin.debug:
        msg: |
          The first service name is {{ service_name }} and the listen port is {{ listen_port }}.

运行剧本:

[ansible@master ansible_playbooks]$ ansible-lint vars_prompt.yml
[ansible@master ansible_playbooks]$ ansible-playbook vars_prompt.yml -v
Using /etc/ansible/ansible.cfg as config file
please input the service name: Tomcat  #<--- 此处输入了服务名称为Tomcat
please input the service listen port [6666]:   #<--- 此处未输入任何值,直接按的回车键,使用了默认的监听端口号6666

PLAY [node1] ***********************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************
ok: [node1]

TASK [display variable from variable list] *****************************************************************************
ok: [node1] => {
    "msg": "The first service name is Tomcat and the listen port is 6666.\n"
}

PLAY RECAP *************************************************************************************************************
node1                      : ok=2    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

[ansible@master ansible_playbooks]$ ansible-playbook vars_prompt.yml -v
Using /etc/ansible/ansible.cfg as config file
please input the service name: tomcat   #<--- 此处输入了服务名称为tomcat
please input the service listen port [6666]:   #<--- 此处输入了服务监听端口号为8080

PLAY [node1] ***********************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************
ok: [node1]

TASK [display variable from variable list] *****************************************************************************
ok: [node1] => {
    "msg": "The first service name is tomcat and the listen port is 8080.\n"
}

PLAY RECAP *************************************************************************************************************
node1                      : ok=2    changed=0    unreachable=0    failed=0    skipped=0    rescued=0    ignored=0

[ansible@master ansible_playbooks]$

效果图如下:

Snipaste_2023-07-23_23-13-49

可以看到,正常获取到了交互模式下用户输入的变量信息,服务名称和服务监听端口号都正常获取到了。

另外,还可以创建加密的变量,用于设置密码信息等。可参考: ansible基础用法6_prompt 交互变量的使用, 后续再进行测试。

8.对用户输入的密码进行加密

在一节中,我们使用vars_prompt获取了用户的输入信息,并存储到变量中,最后打印出了用户的输入。这一节我们通过vars_prompt获取用户输入的密码信息,并进行加密。

8.1 基础知识说明

我们可以查看当前操作系统所使用的密码加密算法:

[root@node1 ~]# authconfig --test|grep hashing
 password hashing algorithm is md5

可以看到,当前系统密码加密算法是md5加密算法。

查看当前操作系统支持的加密算法:

[root@node1 ~]# authconfig --help|grep passalgo
  --passalgo=<descrypt|bigcrypt|md5|sha256|sha512>

如果要修改加密算法,可以使用以下命令:

authconfig --passalgo=sha512 --update

详细可参考: Configuring System Passwords Using authconfig

密码加密算法原理

在Linux系统中,用户密码存储在/etc/passwd文件中。但是,由于该文件权限是任何用户都可以读取的,所以直接将密码明文存储在文件中会造成安全漏洞。因此,Linux系统使用密码加密算法对用户密码进行加密。

Linux密码加密算法使用一个称为“加盐”的过程,即在密码明文的基础上添加一段随机字符串,再进行加密,最后将随机字符串和密码密文一同存储在/etc/shadow文件中。这样做的好处是让攻击者无法预测密码明文和随机字符串,增加了暴力破解密码的难度。

8.2 使用passlib库生成密码

参考:passlib.hash - Password Hashing Schemes

我们此处仅考虑和测试MD5、SHA-256、SHA-512三种加密算法。

由参考文档中已经标记MD5算法不再认为是安全的算法,推荐使用SHA-256或SHA-512加密算法。

我们来测试一下:

[root@master ~]# python3
Python 3.6.8 (default, Nov 16 2020, 16:55:22)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-44)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from passlib.hash import md5_crypt, sha256_crypt, sha512_crypt
# 使用md5加密算法加密
>>> h = md5_crypt.hash("password")
>>> h
'$1$CjxICQF7$JOGLwFLcRheFJoR9YIaPz/'
>>>

# 使用SHA-256加密算法加密
>>> hash = sha256_crypt.hash("password")
>>> hash
'$5$rounds=535000$nhLk2HVjQisH0yV1$zgGQefxxGsiPzWdVXsskOTRQhojts3iOrV3sJH4koQ1'

# 设置轮转次数为12345次
>>> sha256_crypt.using(rounds=12345).hash("password")
'$5$rounds=12345$Q4Gzj5vvcuJHHvSV$JU3lO2oip.mQxomTSxTChhev8vRS7bD79wlMYhzcIXA'

# 使用SHA-512加密算法加密
>>> hash512 = sha512_crypt.hash("password")
>>> hash512
'$6$rounds=656000$0SAk.X3/TEl4Hyko$nNKdA87kzVLaKeYxYUdUmYMMkXDshoNQF94y0FF62ofyz0d17eMVNpa6GePNTgAAisQKwSOf3X7p.IWELz9BT1'

# 使用SHA-512加密算法加密,使用自定义盐为mysalt
>>> hash512 = sha512_crypt.hash("password",salt="mysalt")
>>> hash512
'$6$rounds=656000$mysalt$3.xRZpxy/z008hs6wvfEK57aZTod.CF.Q.4B70uMKJOlUi242tjNpccHhrBMFok8iQxmzChlbZsofydrFB.0G.'

# 使用SHA-512加密算法加密,设置轮转次数为5000
>>> hash512 = sha512_crypt.using(rounds=5000).hash("password",salt="mysalt")
>>> hash512
'$6$mysalt$NN1QGsmCO0hcvplH4ahY6ocho6F6TgcY8yNdMFAeO.LAeFodNPGA6KsQM5Or1AKbE4QKSqnEsC/SE0Zz3ts9y1'

可以看到,根据官方规范,当rounds参数设置为5000时,可以从哈希字符串中省略它。

如果省略rounds轮转次数信息,我们可以看到在密码字符串中,密文由3部分组成,以”$”分隔,第一部分为ID,第二部分为盐值,第三部分为加密密文。

ID与加密算法间的对应关系:

ID值 加密算法
1 MD5
5 SHA-256
6 SHA-512

8.3 使用Ansible加密密码并创建用户

有了以上基础后,我们来使用Ansible加密密码并创建用户。

具体可参考: Hashing values supplied by vars_prompt

编写剧本文件vars_prompt_encrypt.yml

---
- hosts: node1
  # 定义交互式获取变量
  vars_prompt:
    - name: user_name
      prompt: please input the user name
      # 非私有时,会显示输入的变量值
      private: no
    - name: user_password
      prompt: please input the user password
      encrypt: sha512_crypt
      # 需要两次输入密码确认
      confirm: true
      salt_size: 7
      # 私有时。不会显示输入的变量值,对于密码输入的话,可以避免密码泄漏
      private: yes

  tasks:
    - name: Create user
      ansible.builtin.user:
        name: "{{ user_name }}"
        comment: "使用vars_prompt创建用户{{ user_name }}"
        password: "{{ user_password }}"
      become: yes

执行剧本:

[ansible@master ansible_playbooks]$ ansible-lint vars_prompt_encrypt.yml
[ansible@master ansible_playbooks]$ ansible-playbook vars_prompt_encrypt.yml -v
Using /etc/ansible/ansible.cfg as config file
please input the user name: testvar  #<--- 输入用户名
please input the user password:  #<--- 输入密码,如我输入的是password
confirm please input the user password:  #<--- 再次输入密码password

PLAY [node1] ***********************************************************************************************************

TASK [Gathering Facts] *************************************************************************************************
ok: [node1]

TASK [Create user] *****************************************************************************************************
changed: [node1] => {"changed": true, "comment": "使用vars_prompt创建用户testvar", "create_home": true, "group": 1003, "home": "/home/testvar", "name": "testvar", "password": "NOT_LOGGING_PASSWORD", "shell": "/bin/bash", "state": "present", "system": false, "uid": 1003}

[ansible@master ansible_playbooks]$

可以看到,剧本执行成功,效果图如下:

Snipaste_2023-07-25_00-19-19

此时,在节点1上面进行检查:

[root@node1 ~]# grep testvar /etc/passwd
testvar:x:1003:1003:使用vars_prompt创建用户testvar:/home/testvar:/bin/bash
[root@node1 ~]# grep testvar /etc/shadow
testvar:$6$ZPe383L$WJwlTUJ1iPj9cN1ZcH0W352jU.PPpX2lGr.dzhpR0lS/k9.jym3sztBkCXAafWMmbNGWYFcucamv8QDp6izVV/:19562:0:99999:7:::
[root@node1 ~]#

可以看到,用户创建成功,用户的备注信息是"使用vars_prompt创建用户testvar",使用的密码加密算法ID是"6",也就是SHA-512加密算法,生成的7位随机盐是"ZPe383L",而生成的密码密文是“WJwlTUJ1iPj9cN1ZcH0W352jU.PPpX2lGr.dzhpR0lS/k9.jym3sztBkCXAafWMmbNGWYFcucamv8QDp6izVV/”。

尝试远程登陆:

$ ssh testvar@cloud-node1
testvar@cloud-node1's password:
Welcome to node1
[testvar@node1 ~]$ whoami
testvar
[testvar@node1 ~]$

可以看到,能成功登陆,说明刚才创建的用户配置是正确的!

最后,在节点node1上面删除刚才创建的用户testvar:

[root@node1 ~]# userdel --help
Usage: userdel [options] LOGIN

Options:
  -f, --force                   force some actions that would fail otherwise
                                e.g. removal of user still logged in
                                or files, even if not owned by the user
  -h, --help                    display this help message and exit
  -r, --remove                  remove home directory and mail spool
  -R, --root CHROOT_DIR         directory to chroot into
  -P, --prefix PREFIX_DIR       prefix directory where are located the /etc/* files
  -Z, --selinux-user            remove any SELinux user mapping for the user

[root@node1 ~]# userdel -r testvar
[root@node1 ~]# grep testvar /etc/passwd
[root@node1 ~]# grep testvar /etc/shadow
[root@node1 ~]#

这样,测试用户就删除成功了。

谨此笔记,记录过往。凭君阅览,如能收益,莫大奢望。
