MongoDB mongorestore 故障: locale: : facet: :_S_create_c_locale 名称无效

我在计算机 A (ubuntu12.04服务器)上创建了一个转储。我把它移动到计算机 B (ubuntu 12.04服务器)并输入:

Mongorest-db db _ name ——删除 db _ dump _ path

它失败了，并报告说:

连接到: 127.0.0.1
在抛出‘ std: : run _ error’实例后调用 finally
What () : locale: : facet: : _ S _ create _ c _ locale name 无效
流产了

我以前成功完成过这次行动这种奇怪的行为从未发生过。我要怎么做才能解决这个问题？

Actually it isn't strictly related to MongoDB. Somehow the language on computer B was not defined correctly. I managed to fix it by typing:

sudo locale-gen en_US en_US.UTF-8
sudo locale-gen it_IT it_IT.UTF-8
sudo locale-gen xx_xx xx_XX.UTF-8 ...
sudo dpkg-reconfigure locales

These commands will generate and configure the needed locales. After those steps mongorestore got back working as usual.

On my distro "locale-gen" was not installed and it turned out all I had to do is set the LC_ALL environment variable. so the following command fixed it:

export LC_ALL="en_US.UTF-8"

hopefully it will help someone else...

Got same problem on debian 7 without locale-gen (command not found) installed.

I solved this way:

su
apt-get install locales
dpkg-reconfigure locales # select locales you want!

Now mongodb should start.

If you are using a Mac OSX and SSH this might be issued by wrong LC_CTYPE. 

$ locale
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE=UTF-8
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

Unset the wrong var. 

$ unset LC_CTYPE

Check whether locale is working fine. 

$ locale
LANG=en_US.UTF-8
LANGUAGE=
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

Now mongo also should do fine.

To make the fix permanent you can edit one of those files:

  • sudo vim /etc/default/locale
  • sudo vim /etc/environment

And add the line LC_ALL="en_US.UTF-8"

Exporting LC_ALL="en_US.UTF-8" only works if you have the en_US locale installed. If you want to avoid installing the locales package (or its equivalent on distributions other than Debian derivatives), then you can instead use:

export LC_ALL=C.UTF-8

which will not require any extra locale data.
