MongoDB安装Ubuntu 12.04 LTS错误

Question

在干净，新鲜的Ubuntu 12.04 LTS服务器上安装MongoDB时，我需要一些帮助，而无需安装废话。 我以为这是小菜一碟，但是我遇到了一些错误，Ubuntu论坛没有我想要的答案。

在开始实际安装MongoDB之前，我希望服务器是最新的，因此输入：

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

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

$ 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

至此，我已经安装了MongoDB。 众所周知，要使用MongoDB，您需要使用终端启动它，然后，您将能够使用单独的终端/连接进行连接。

因此，我输入：

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

当然，在执行我自己的研究之前，我不想立即使用stackoverflow。 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，这不能正常工作，因此我需要继续搜索。 我想出了另一种解决方案：使用GRUB_CMDLINE_LINUX_DEFAULT =“ transparent_hugepage = never”编辑/ etc / default / grub文件 ，然后得到以下信息：

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.

因此，实际上我不知道出了什么问题。 我在互联网上四处张望，找不到确切的答案。 就像网站上所述，我进行了全新安装。 几个月前，我完成了相同的教程，并且在2.6.x版本（3.0.1）中一切正常。

你们能帮我吗？ 任何意见/提示/技巧将不胜感激:)

Answer 1

使用apt-get安装后，您无需手动启动mongod。 您可以使用以下命令启动和停止服务器

# service mongod start

和

# service mongod stop

第一次键入mongo并得到：

MongoDB shell version: 3.0.1
connecting to: test

服务器已启动并正在运行。

如果您现在遇到此错误：

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

您可以运行以下命令启动mongo shell，声明变量LC_ALL：

# LC_ALL=C mongo

Answer 2

转到编辑文件/etc/default/locale并设置

LANG= LANGUAGE= LC_ALL=

设置为您的首选设置。 举个例子：

$ vim /etc/default/locale LANG=en_US.UTF-8 LANGUAGE=en_US LC_ALL=en_US.UTF-8
