无法使用TypeORM + pgAdmin4连接到在docker上运行的本地PostgreSQL数据库

如何解决无法使用TypeORM + pgAdmin4连接到在docker上运行的本地PostgreSQL数据库

我在本地主机上运行的docker上托管了一个postgres数据库，并使用默认的postgres端口5432，但是我完全无法通过pgAdmin4或TypeORM连接到该数据库。两者都抛出相同的错误提示密码无效。

我正在使用以下docker-compose.yml文件创建数据库：

version: '3.8'
services: 
    db:
        image: postgres
        volumes:
            - ./pgdata:/var/lib/postgresql/data
        ports: 
            - '5432:5432'
        environment: 
            POSTGRES_DB: maindb
            POSTGRES_USER: admin
            POSTGRES_PASSWORD: admin

因此，我希望能够通过输入localhost上的默认端口5432（也尝试使用localhost ip 127.0.0.1）通过pgAdmin4连接到数据库，但是当我尝试使用以下凭据登录时（您必须相信我，密码输入正确并输入10次并复制粘贴）

当我按登录时，出现以下错误：

Unable to connect to server:

FATAL: password authentication failed for user "admin"

这真的很奇怪，因为我看不出它为什么会失败。我100％肯定通过了环境变量，就像在docker桌面上一样，我可以看到它们是相同的。

我还尝试通过以下方式通过TypeORM连接到数据库：

createConnection({
    type: 'postgres',host: 'localhost',port: 5432,username: 'admin',password: 'admin',database: 'maindb',entities: [App],synchronize: true,logging: false,})
    .then(connection => console.log('Logged in'))
    .catch(error => console.log(error));

我收到此错误消息：

error: password authentication failed for user "admin"
REMOVED PATHS FOR CONCISENESS
 {
  length: 97,severity: 'FATAL',code: '28P01',detail: undefined,hint: undefined,position: undefined,internalPosition: undefined,internalQuery: undefined,where: undefined,schema: undefined,table: undefined,column: undefined,dataType: undefined,constraint: undefined,file: 'auth.c',line: '285',routine: 'auth_failed'
}

我也没有理由认为这应该失败。我想知道这是PostgreSQL问题还是docker问题？对我来说，切换数据库提供者可能更容易？

解决方法

在初始化脚本中设置了用户名和密码。

如果这不是您第一次在该文件上运行组合，则很可能您已经在容器中装入的卷上已有数据。在这种情况下，跳过初始化脚本，您应该在docker-compose up输出中看到以下日志：

db_1  | PostgreSQL Database directory appears to contain a database; Skipping initialization

以下任何选项都可以解决您的问题：

记住您组成时第一次设置的密码并使用该密码进行连接

清空该卷或将其完全删除（@pacuna已在注释中说明了如何进行此操作-这将清除数据并重新初始化所有内容！）

docker-compose down -v

重置管理员密码：

// Open a console in the container
docker exec -ti <your-psql-container-id> sh

// Connect to your maindb using the admin user
psql -d maindb -U admin

// Change the admin user password
ALTER USER admin WITH ENCRYPTED PASSWORD 'admin-new-pass';

...然后使用 admin-new-pass

重试连接
