无法在 Ubuntu 12 规范云映像上运行 PostgreSQL答案

【问题标题】：Unable to run PostgreSQL on Ubuntu 12 Canonical Cloud Image无法在 Ubuntu 12 规范云映像上运行 PostgreSQL
【发布时间】：2014-07-10 12:59:52
【问题描述】：

我使用 Vagrant 1.5 和标准 Vagrantfile 和 Canonical Ubuntu 12 Box
然后我使用vagrant ssh 登录VM 并执行以下命令：

sudo apt-get install postgresql postgresql-contrib python-psycopg2 -y
sudo -u postgres psql

并得到这样的错误：

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"?

这很奇怪，这个步骤在official docs中有描述。可能是什么问题？

更新

Postgres 进程在安装后没有立即运行，我用ps -ef | grep postgr 命令检查了它。 sudo service postgresql status 什么也不返回。这是packegs安装的完整日志：https://gist.github.com/AndrewPashkin/2292aa9a53154217ff39

有一些有趣的台词：

Error: The locale requested by the environment is invalid.
Error: could not create default cluster. Please create it manually with

pg_createcluster 9.1 main --start

在我尝试执行此命令后，我得到：

$  pg_createcluster 9.1 main --start
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LC_PAPER = "ru_RU.UTF-8",
        LC_ADDRESS = "ru_RU.UTF-8",
        LC_MONETARY = "ru_RU.UTF-8",
        LC_NUMERIC = "ru_RU.UTF-8",
        LC_TELEPHONE = "ru_RU.UTF-8",
        LC_IDENTIFICATION = "ru_RU.UTF-8",
        LC_MEASUREMENT = "ru_RU.UTF-8",
        LC_TIME = "ru_RU.UTF-8",
        LC_NAME = "ru_RU.UTF-8",
        LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
Error: The locale requested by the environment is invalid.

所以这是语言环境问题。我已经尝试过的：

sudo apt-get install language-pack-en -y

没有帮助。并且：

sudo update-locale LANG=en_US.UTF-8 LC_MESSAGES=POSIX

失败：

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LC_PAPER = "ru_RU.UTF-8",
        LC_ADDRESS = "ru_RU.UTF-8",
        LC_MONETARY = "ru_RU.UTF-8",
        LC_NUMERIC = "ru_RU.UTF-8",
        LC_TELEPHONE = "ru_RU.UTF-8",
        LC_IDENTIFICATION = "ru_RU.UTF-8",
        LC_MEASUREMENT = "ru_RU.UTF-8",
        LC_TIME = "ru_RU.UTF-8",
        LC_NAME = "ru_RU.UTF-8",
        LC_MESSAGES = "POSIX",
        LANG = "en_US.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

【问题讨论】：

嗯，它正在运行吗？ apt 安装的日志在哪里？显示它正在运行的服务器日志在哪里？您如何期望人们在没有最起码的信息的情况下提供帮助？
@RichardHuxton 你的评论实际上让我知道了问题的真正原因 - 仔细查看安装日志发现了一些有用的细节
很奇怪。我从未见过像这样混在一起的两个语言环境。尽管如此，这就是日志存在的原因，否则您可能需要花费数天时间才能弄清楚这一点。

【解决方案1】：

我通过运行以下行解决了这个问题：

echo "echo $'LANGUAGE=en_US.UTF-8\n' > /etc/default/locale" | sudo -s;
echo "echo $'LANG=en_US.UTF-8\n' >> /etc/default/locale" | sudo -s;
echo "echo $'LC_ALL=en_US.UTF-8\n' >> /etc/default/locale" | sudo -s;
echo "echo $'LC_MESSAGES=POSIX\n' >> /etc/default/locale" | sudo -s;
sudo locale-gen en_US.UTF-8;
sudo dpkg-reconfigure locales;
