centos6 中的 locale-gen 命令

Question

在我的裸 centos6.5 系统中，它是一个docker容器，en_US.utf-8缺少语言环境：

bash-4.1# locale -a
C
POSIX

通常在 Ubuntu 中有locale-gen执行此操作的命令：

# locale-gen en_US.UTF-8
# echo 'LANG="en_US.UTF-8"' > /etc/default/locale

我怎么能在centos 6.5中做到这一点？

Answer 1

locale-gen中不存在Centos/Fedora。

您必须使用localedef：

localedef -v -c -i en_US -f UTF-8 en_US.UTF-8

来自man localedef：

NAME
       localedef - define locale environment

SYNOPSIS
       localedef [-c][-f charmap][-i sourcefile][-u code_set_name] name

DESCRIPTION
       The localedef utility shall convert source definitions for locale cate?
       gories into a format usable by the functions and utilities whose opera?
       tional behavior is determined by the setting of the locale  environment
       variables    defined    in    the    Base    Definitions    volume   of
       IEEE Std 1003.1-2001, Chapter 7, Locale. It  is  implementation-defined
       whether users have the capability to create new locales, in addition to
       those  supplied  by  the  implementation.  If  the  symbolic   constant
       POSIX2_LOCALEDEF  is  defined,  the system supports the creation of new
       locales.    On   XSI-conformant   systems,   the   symbolic    constant
       POSIX2_LOCALEDEF shall be defined.

Answer 2

我根据答案@Gnouc 提供了额外的信息（localedef应在 centos 中使用）

这centos docker是一个提供最少包的特殊图像，请参阅脚本https://github.com/dotcloud/docker/blob/master/contrib/mkimage-yum.sh

rm -rf "$target"/usr/{{lib,share}/locale,{lib,lib64}/gconv,bin/localedef,sbin/build-locale-archive}

localedef删除内部命令，glibc-common应重新安装包含此命令的软件包

yum reinstall glibc-common

肯定会增加尺寸
