MongoDB安裝Ubuntu 12.04 LTS錯誤

Question

在干凈，新鮮的Ubuntu 12.04 LTS服務器上安裝MongoDB時，我需要一些幫助，而無需安裝廢話。 我以為這是小菜一碟，但是我遇到了一些錯誤，Ubuntu論壇沒有我想要的答案。

在開始實際安裝MongoDB之前，我希望服務器是最新的，因此輸入：

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

我從MongoDB轉到網站（ http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ ），並按照他們的教程進行操作，所以我輸入了：

$ 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，我已經安裝了MongoDB。 眾所周知，要使用MongoDB，您需要使用終端啟動它，然后，您將能夠使用單獨的終端/連接進行連接。

因此，我輸入：

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

ubuntu-user@ubuntu-vm:~$ mongod

當然，在執行我自己的研究之前，我不想立即使用stackoverflow。 我上網尋找答案，發現很多人使用“ export LC_ALL = C”來解決變量問題。 我也嘗試使用dpkg。

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

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

顯然，這不能正常工作，因此我需要繼續搜索。 我想出了另一種解決方案：使用GRUB_CMDLINE_LINUX_DEFAULT =“ transparent_hugepage = never”編輯/ 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，實際上我不知道出了什么問題。 我在互聯網上四處張望，找不到確切的答案。 就像網站上所述，我進行了全新安裝。 幾個月前，我完成了相同的教程，並且在2.6.x版本（3.0.1）中一切正常。

你們能幫我嗎？ 任何意見/提示/技巧將不勝感激:)

Answer 1

使用apt-get安裝后，您無需手動啟動mongod。 您可以使用以下命令啟動和停止服務器

# service mongod start

和

# service mongod stop

第一次鍵入mongo並得到：

MongoDB shell version: 3.0.1
connecting to: test

服務器已啟動並正在運行。

如果您現在遇到此錯誤：

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

您可以運行以下命令啟動mongo shell，聲明變量LC_ALL：

# LC_ALL=C mongo

Answer 2

轉到編輯文件/etc/default/locale並設置

LANG= LANGUAGE= LC_ALL=

設置為您的首選設置。 舉個例子：

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