Installing postgres on EC2 (Amazon Linux)
提问by user3219511
Trying to install postgreSQL, and looks liked I have messed something up. I first delete postgres using commands below.
尝试安装 postgreSQL，看起来我搞砸了。我首先使用下面的命令删除 postgres。
[ec2-user@ip-10-183-130-45 /]$ rm -rf /var/lib/pgsql/data
[ec2-user@ip-10-183-130-45 /]$ sudo rm -rf /var/pgsql
then try initdb, which for some reason fails,
然后尝试 initdb，它由于某种原因失败了，
[ec2-user@ip-10-183-130-45 /]$ sudo service postgresql initdb
Initializing database: [FAILED]
but when I check though, the initdb does create pgsql folder,
但是当我检查时，initdb 确实创建了 pgsql 文件夹，
[ec2-user@ip-10-183-130-45 var]$ ls -l
total 80

so I try to start the postgresql, which fails too
所以我尝试启动 postgresql，它也失败了
[ec2-user@ip-10-183-130-45 var]$ sudo service postgresql start
/var/pgsql is missing. Use "service postgresql initdb" to initialize
the cluster first.
[FAILED]
Can someone help, ID what I am doing wrong? Using postgresql-9.2-1.19.
有人可以帮忙，找出我做错了什么吗？使用 postgresql-9.2-1.19。

I think there is a misunderstanding. Did you say that you deleted some postgres files, and then are wondering why it doesn't work?
我认为存在误解。你是不是说你删除了一些postgres文件，然后想知道为什么它不起作用？
I recommend:
我建议：
- Repairing the original install of postgres.
- Removing it gracefully. With the package manager perhaps?
- Installing your new postgres with a package manager.
- 修复 postgres 的原始安装。
- 优雅地删除它。也许与包管理器？
- 使用包管理器安装新的 postgres。
