Lion更新删除了“ postgres”用户。如何还原？ [英] Lion update removed the 'postgres' user. How to restore it?

问题描述

几个月前，我已经使用kyngchaos安装程序安装了postgres。我现在已经更新到OSX Lion，但是数据库服务器无法启动。

I've installed postgres with the kyngchaos installer a couple of months ago. I've now updated to OSX Lion, but the database server fails to start.

对kyngchaos博客的评论（ http://www.kyngchaos.com/blog/2011/20110723_lion ）使我看到了 postgres用户：该用户不存在不再！至少，我不能再 sudo su postgres了。因此，我认为这是服务器无法运行的原因。

A comment on kyngchaos's blog (http://www.kyngchaos.com/blog/2011/20110723_lion) made me look at the 'postgres' user: it doesn't exist anymore! At least, I can't "sudo su postgres" anymore. So I figure that's the reason my server doesn't run.

如何最好地还原该用户？

How can I best restore that user?

推荐答案

（回答自己）

最后，我唯一需要做的就是重新创建 postgres用户。事先，我列出了 / usr / local / pgsql / 的内容，并发现例如 data / 目录是由用户 101 和组 postgres 拥有。因此，我想将该postgres用户绑定到101个用户ID：

In the end, the only thing I needed to do was to re-create the "postgres" user. Beforehand, I listed the contents of /usr/local/pgsql/ and saw that for instance the data/ directory was owned by user 101 and group postgres. So I wanted to tie that postgres user to the 101 userid:

sudo dscl . -create /Users/postgres
sudo dscl . -create /Users/postgres UniqueID 101

（然后我重新启动了Mac，因为我不知道如何手动启动该postgres服务器...;-）

(And afterwards I restarted my mac as I didn't know how to start that postgres server by hand... ;-)
