我在一个干净，新鲜的Ubuntu 12.04 LTS服务器上安装我的MongoDB需要一些帮助，没有安装废话。我认为这将是一块蛋糕，但我有一些错误，Ubuntu论坛没有得到我想要的答案。
在开始实际安装MongoDB之前，我希望服务器是最新的，所以我键入了：
$ 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/）访问了网站并按照他们的教程进行了操作，因此我键入了：
$ 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
此时我安装了MongoDB。就像我们都知道的那样，为了使用MongoDB，您需要使用终端启动它，之后您就可以使用分离的终端/连接进行连接。
所以，我打字：
ubuntu-user@ubuntu-vm:~$ mongo
MongoDB shell version: 3.0.1
connecting to: test

当然，在我先做自己的调查之前，我不想马上使用stackoverflow。我上网寻找答案，我注意到很多人使用＆＃34;导出LC_ALL = C＆＃34;修复变量问题。我也尝试过使用dpkg。
ubuntu-user@ubuntu-vm:~$ export LC_ALL=C
ubuntu-user@ubuntu-vm:~$ dpkg-reconfigure locales

显然，这不能正常工作，所以我需要继续搜索。我提出了另一个解决方案：使用 GRUB_CMDLINE_LINUX_DEFAULT =＆＃34; transparent_hugepage = never＆＃34; 编辑 / etc / default / grub文件然后我得到了这个：< / p>
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。我浏览了整个互联网，无法找到我想要的确切答案。我做了一个干净的安装就像网站说的那样。几个月前，我做了相同的教程，一切都运行良好，版本2.6.x，这是3.0.1。
你可以帮帮我吗？任何评论/提示/技巧将真诚地感谢：）编辑1 - 回复费尔南多

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
您第一次输入mongo并获得：
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.
您可以启动mongo shell声明变量LC_ALL，运行：
# LC_ALL=C mongo

转到编辑文件/etc/default/locale并设置
LANG=
LANGUAGE=
LC_ALL=
到您的首选设置。举个例子：
$ vim /etc/default/locale
LANG=en_US.UTF-8
LANGUAGE=en_US
LC_ALL=en_US.UTF-8
