Wiki.js 未运行数据库连接错误

问题描述

Windows Enterprise 2016 LTSB 版本 1607。安装了 Wiki.js 和 Postgresql。之前安装过 Node.js (v12.16.2)。

使用 Powershell 进入 wiki.js 安装过程的step 8：

node server

我收到此错误：

PS C:\wiki> node server

我意识到我忘记创建一个 Postgresql，所以我使用 pgAdmin4.28 创建了一个“wiki”数据库。错误现在更改为：

PS C:\wiki> node server

请发送帮助！我感谢所有评论。谢谢！

解决方法

我的环境如下：Windows 10专业版号20h2节点版v14.15.4 PostgreSQL V 13.1，报错内容如下：

Loading configuration from D:\dev\workspace\wiki\config.yml... OK

你只需要将 config.yml 中的数据库配置修改如下：

db:
  type: postgres

  # PostgreSQL / MySQL / MariaDB / MS SQL Server only:
  host: localhost
  port: 5432
  user: postgres #YOU PostgreSQL USERNAME
  pass: willasas@wiki. #YOU PostgreSQL PASSWORD
  db: wiki #YOU DATABASE NAME
  ssl: false

然后运行代码

node server

然后在浏览器地址栏输入http://127.0.0.1 : 3000 /并行回车

,

我在使用 postgres 和 wiki.js 时遇到了类似的问题。 解决方案是在 postgres 中手动创建数据库，BEFORE 运行 node server:

CREATE DATABASE wiki

希望这可以为您节省我为解决这个问题而花费的时间。

经过几个小时的测试后，我意识到在 wiki.js 中使用 postgres 存在一些问题。这些是您可以在 config.yml 中尝试的一些建议：

db:
  type: postgres
  
  # if you are using docker try using IP instead of localhost
  host: localhost
  port: 5432
  
  # don't use _ here. It'll cause connection error undefined.
  user: wikijs
  
  # start with letter,if you start with @ it will throw an error.
  # I used a 18 long pass without any problem. Ex:
  pass: wiki@projectW777!@
  
  # you can use _ here. Ex:
  db: prj_wiki

,

如果您需要更改数据库密码，这可以帮助您：

ALTER USER postgres WITH PASSWORD 'xxx';
