我正在尝试在 Vagrant VM 上使用 Ansible 安装 PostgreSQL 和 Postgis。 但是我在安装和访问 PostgreSQL 时遇到了一些问题（还没有达到 Postgis 的步骤）。
我的 Vagrant VM 是一个 ubuntu/jammy64.
首先，我在虚拟机上安装了PHP。
然后我尝试安装 PostrgreSQL。接下来，我对 Ansible 的 psql 任务：
---
- name: Install
apt:
update_cache: true
name:
- bash
- openssl
- libssl-dev
- libssl-doc
- postgresql
- postgresql-contrib
- libpq-dev
- python3-psycopg2
state: present
- name: Check if initialized
stat:
path: "{{ postgresql_data_dir }}/pg_hba.conf"
register: postgres_data
- name: Empty data dir
file:
path: "{{ postgresql_data_dir }}"
state: absent
when: not postgres_data.stat.exists
- name: Initialize
shell: "{{ postgresql_bin_path }}/initdb -D {{ postgresql_data_dir }}"
become: true
become_user: postgres
when: not postgres_data.stat.exists
- name: Start and enable service
service:
name: postgresql
state: started
enabled: true
- name: "Create database {{ postgresql_db }}"
become: true
become_user: "{{ postgresql_user }}"
postgresql_db:
name: "{{ postgresql_db }}"
state: present
- name: "Create user {{ user }}"
become: yes
become_user: "{{ postgresql_user }}"
postgresql_user:
name: "{{ user }}"
password: "{{ user }}"
state: present
- name: "Grant user {{ user }}"
become: yes
become_user: "{{ postgresql_user }}"
postgresql_privs:
type: database
database: "{{ postgresql_db }}"
roles: "{{ user }}"
grant_option: no
privs: all
notify: psql restart
我的变量：
---
postgresql_version: 14
postgresql_bin_path: "/usr/lib/postgresql/{{ postgresql_version }}/bin"
postgresql_data_dir: "/var/lib/postgresql/{{ postgresql_version }}/main"
postgresql_host: localhost
postgresql_port: 5432
postgresql_db: "db_{{ user }}"
postgresql_user: {{ user }}
postgresql_password: {{ user }}
ansible_ssh_pipelining: true
但是当我玩 Ansible 的剧本时，我得到以下反馈：

PLAY RECAP *********************************************************************

你们能告诉我我的错误在哪里吗？是我的 PostgreSQL 安装错了吗？
感谢您的反馈！
