Question

Ubuntu 14 我在远程服务器（digitalocean）上安装postgresql服务器。

运行命令psql并显示错误：

postgres@ubuntu-512mb-fra1-01:/home/deploy$ psql
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LC_PAPER = "be_BY.UTF-8",
    LC_ADDRESS = "be_BY.UTF-8",
    LC_MONETARY = "be_BY.UTF-8",
    LC_NUMERIC = "be_BY.UTF-8",
    LC_TELEPHONE = "be_BY.UTF-8",
    LC_IDENTIFICATION = "be_BY.UTF-8",
    LC_MEASUREMENT = "be_BY.UTF-8",
    LC_TIME = "be_BY.UTF-8",
    LC_NAME = "be_BY.UTF-8",
    LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
psql: could not connect to server: No such file or directory
    Is the server running locally and accepting
    connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"?

我想重新加载postgresql服务器，运行命令service postgresql start --force

* No PostgreSQL clusters exist; see "man pg_createcluster"

我认为区域设置有问题。但是如何解决这个错误？

Answer 1

区域设置警告无法阻止psql连接。请阅读https://askubuntu.com/questions/162391/how-do-i-fix-my-locale-issue。

不存在PostgreSQL集群

表示您可能没有创建群集。像pg_createcluster -p 2345 9.5 test一样运行smth来创建一个测试集群，或者更好地阅读Ubuntu建议的man pg_createcluster

Answer 2

走这条路

找到群集
```
pg_lsclusters
```
删除群集（使用上面的信息）
```
pg_dropcluster --stop 9.3 main
```

重新创建群集

pg_createcluster --locale en_US.UTF-8 --start 9.3 main

登录postgres
```
sudo -u postgres psql
```
并检查区域设置
```
show LC_COLLATE;
show LC_CTYPE;
```

Postgresql：无法连接到服务器：没有这样的文件或目录
