Ansible Playbook在wp-cli上安装WordPress时出错

问题描述

我正在使用ansible剧本（可使用2.9版）通过wp-cli工具安装wordpress。

这是剧本：

- name: Create wordpress database
  MysqL_db: name="{{ db_name }}"
            state=present
            login_user=root
            login_password="{{ MysqL_root_password }}"

- name: Create wordpress DB user and grant permissions to wordpress DB
  MysqL_user: name="{{ db_user }}"
              password="{{ db_pwd }}"
              priv="{{ db_name }}.*:ALL"
              state=present
              login_user="root"
              login_password="{{ MysqL_root_password }}"

- name: Is wordpress downloaded?
  stat: path="/var/www/{{ domain_name }}/html/index.PHP"
  register: wp_dir

- name: Download wordpress
  command: wp core download
  args:
      chdir: "/var/www/{{ domain_name }}/html/"
  remote_user: "{{ web_user }}"
  when: wp_dir.stat.isdir is not defined

- name: Configure wordpress
  command: wp core config
           --path="/var/www/{{ domain_name }}/html"
           --dbname="{{ db_name }}"
           --dbuser="{{ db_user }}"
           --dbpass="{{ db_pwd }}"
           --dbprefix="{{ db_prefix }}"
  remote_user: "{{ web_user }}"
  when: wp_dir.stat.isdir is not defined

- name: Is wordpress installed?
  command: wp core is-installed
  args:
    chdir: "/var/www/{{ domain_name }}/html/"
  register: wordpress_is_installed
  ignore_errors: True
  remote_user: "{{ web_user }}"

- name: Install wordpress tables
  command: wp core install
            --url="{{ wp_home_url }}"
            --title="{{ wp_site_title }}"
            --admin_user="{{ wp_admin_user }}"
            --admin_password="{{ wp_admin_pwd }}"
            --admin_email="{{ wp_admin_email }}"
  args:
      chdir: "/var/www/{{ domain_name }}/html/"
  when: wordpress_is_installed|Failed
  remote_user: "{{ web_user }}"

在“下载wordpress”任务中，出现致命错误：

“错误：YIKES！您似乎是以root身份运行此文件。您可能打算以wordpress安装所在的用户身份运行它。”

我以sudo用户（主机文件中的“ ansible_user”）运行剧本。而且我还设置了一个额外的用户来管理wordpress设置（remote_user：“ {{web_user}}”）。

任何帮助将不胜感激！

解决方法

在任务中，您需要使用become和become_user代替remote_user，如下所示：

- name: Download WordPress
  command: wp core download
  args:
      chdir: "/var/www/{{ domain_name }}/html/"
  become: yes
  become_user: "{{ web_user }}"
  when: wp_dir.stat.isdir is not defined

,

现在运行相同代码时出现不同的错误：

FAILED! => {"msg": "Failed to set permissions on the temporary files Ansible needs to create when becoming an unprivileged user (rc: 1,err: chown: changing ownership of '/var/tmp/ansible-tmp-1613648876.307028-8235-221563540981220/': Operation not permitted\nchown: changing ownership of '/var/tmp/ansible-tmp-1613648876.307028-8235-221563540981220/AnsiballZ_command.py': Operation not permitted\n}). For information on working around this,see https://docs.ansible.com/ansible/become.html#becoming-an-unprivileged-user"}

我将 Ansible 更新到最新可用版本 (2.10)。

到目前为止我发现的唯一解决方案是将 allow_world_readable_tmpfiles = Yes 添加到 ansible.cfg 文件...

有什么想法吗？

谢谢
