这是我第一次在Windows 8.1上设置数据库(PostgreSQL 12)
从该领域的许多相关问题中寻找解决方案已经花费了4天的时间,但未能成功找到答案(无论是我听不懂还是在我的情况下他们没有用)。
因此,在这里,我将逐步说明每个阶段我做了什么以及遇到什么错误(它们可能不会互相影响,但我会提及所有错误):
当我以管理员身份安装PostgreSQL时,在过程结束时出现以下错误:“无法将SQL模块加载到数据库集群中”,我重新安装了两次,但每次都弹出。在这里,在这篇文章中,我发现有人遇到相同的问题,但是不幸的是,我在技术上不了解解决方案:在PostgreSQL安装期间无法将sql模块加载到数据库集群中。因此,我只是跳过了它,一切似乎都还好。
然后,在高级系统设置中设置PATH->环境变量(在用户变量和系统变量框中),如下所示:“; C:\ Program Files \ PostgreSQL \ 12 \ bin; C:\ Program Files \ PostgreSQL \ 12 \ lib“
此步骤之后,我使用ctrl + R打开一个终端并输入cmd.exe,然后输入以下代码:
> cd C:\Program Files\PostgreSQL\12\bin
> initdb -U postgres -A password -E utf8 -W -D .\PostgreSQL\12\data
我在这里收到此消息:
The files belonging to this database system will be owned by user "pc".
This user must also own the server process.
The database cluster will be initialized with locale "English_United States.1252".
The default text search configuration will be set to "english".
Data page checksums are disabled.
Enter new superuser password:
Enter it again:
输入密码后,出现此错误:
The files belonging to this database system will be owned by user "pc".
This user must also own the server process.
The database cluster will be initialized with locale "English_United
States.1252".
The default text search configuration will be set to "english".
Data page checksums are disabled.
Enter new superuser password:
Enter it again:
creating directory /PostgreSQL/12/data ... ok

selecting default shared_buffers ... 128MB

Success. You can now start the database server using:
pg_ctl -D ^"^\PostgreSQL^\12^\data^" -l logfile start
但是在输入建议的代码时(无论使用日志文件还是其他文件名),我总是收到此消息:
waiting for server to start....Access is denied.
stopped waiting
pg_ctl: could not start server
Examine the log output.
另一方面,当我尝试使用pgAdmin4浏览器界面时,当我右键单击服务器->创建->在弹出窗口中的服务器时,我填写了以下字段:
在“常规”选项卡上,将“名称”框填充为“ dbserver”,将“用户名”设置为“ postgres”,然后在“连接”选项卡上,将“主机”设置为“ localhost”,将“密码”设置为之前的设置
这是我得到的错误:
Unable to connect to server: could not connect to server: Connection refused (0x0000274D/10061) Is
the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not
connect to server: Connection refused (0x0000274D/10061) Is the server running on host "localhost"
(127.0.0.1) and accepting TCP/IP connections on port 5432?
有人可以帮我解决这个问题吗?
谢谢
答案 0 :(得分:0)
因此,我找到了答案,并且想分享。我打开了postgres.conf文件,并注释了logging_collector,log_directory和log_destination。我保存了文件。
然后在终端中,输入如下所示的建议代码:
pg_ctl -D ^"^\PostgreSQL^\12^\data^" start
服务器启动。
现在在pgAdmin4浏览器中,问题也消失了。
