linux - MongoDB安装Ubuntu 12.04 LTS报错

Question

我需要一些帮助来帮助我在干净、全新的 Ubuntu 12.04 LTS 服务器上安装我的 MongoDB，没有安装废话。我以为这会是小菜一碟，但我遇到了一些错误，而且 Ubuntu 论坛没有我正在寻找的答案。

在我开始实际安装 MongoDB 之前，我希望服务器是最新的，所以我输入:

$ sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade

我从 MongoDB (http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/) 访问网站并按照他们的教程进行操作，所以我输入:

$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10
$ echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.0.list
$ sudo apt-get update
$ sudo apt-get install -y mongodb-org

此时我已经安装了 MongoDB。众所周知，为了使用 MongoDB，您需要使用终端启动它，之后您将能够连接到一个单独的终端/连接。

所以，我输入:

ubuntu-user@ubuntu-vm:~$ mongo
MongoDB shell version: 3.0.1
connecting to: test

当然，我不想马上使用 stackoverflow，先做我自己的调查。我上网寻找答案，发现很多人使用“export LC_ALL=C”来解决变量问题。我也尝试过使用 dpkg。

ubuntu-user@ubuntu-vm:~$ export LC_ALL=C

ubuntu-user@ubuntu-vm:~$ dpkg-reconfigure locales
root@ubuntu-vm:~# dpkg-reconfigure locales

显然，这并不能正常工作，所以我需要继续搜索。我想到了另一个解决方案:使用 GRUB_CMDLINE_LINUX_DEFAULT="transparent_hugepage=never" 编辑 /etc/default/grub 文件 然后我得到了这个:

ubuntu-user@ubuntu-vm:~$ mongo
Failed global initialization: BadValue Invalid or no user locale set.
Please ensure LANG and/or LC_* environment variables are set correctly.

ubuntu-user@ubuntu-vm:~$ mongod
2015-03-27T12:56:19.085+0100 F CONTROL  Failed global initialization:
BadValue Invalid or no user locale set. Please ensure LANG and/or LC_*
environment variables are set correctly.

所以，实际上我不知道出了什么问题。我在互联网上到处找，找不到我要找的确切答案。就像网站上说的那样，我进行了全新安装。几个月前，我做了同样的教程，一切都运行良好，版本 2.6.x，这是 3.0.1。

你们能帮帮我吗？任何评论/提示/技巧将不胜感激:)

使用 apt-get 安装后，您无需手动启动 mongod。您可以使用

启动和停止服务器

# service mongod start

和

# service mongod stop

第一次输入 mongo 时得到:

MongoDB shell version: 3.0.1
connecting to: test

服务器已启动并正在运行。

如果你现在有这个错误:

Failed global initialization: BadValue Invalid or no user locale set. Please ensure LANG and/or LC_* environment variables are set correctly.

您可以启动 mongo shell，声明变量 LC_ALL，运行:

# LC_ALL=C mongo
