Centos: 解决系统编码 locale 的 LC_CTYPE / LC_ALL 问题
0 系统环境
CentOS 7.4
# rpm -q centos-release
centos-release-7-4.1708.el7.centos.x86_64
初装的系统，如果输入 locale 查看系统字体编码，可能会出现报错
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
或者设置编码不完全时，会出现警告
LC_CTYPE: cannot change locale (UTF-8): No such file or directory
2 解决方法
如果要设置中文版的字体编码。在每个文件中增加以下内容。
# vim /etc/profile.d/locale.sh
export LC_CTYPE=zh_CN.UTF-8
export LC_ALL=zh_CN.UTF-8
# vim /etc/locale.conf
LANG=zh_CN.UTF-8
# vim /etc/sysconfig/i18n
LANG=zh_CN.UTF-8
# vim /etc/environment
LANG=zh_CN.UTF-8
LC_ALL=zh_CN.UTF-8
# vim /etc/profile.d/locale.sh
export LC_CTYPE=en_US.UTF-8
export LC_ALL=en_US.UTF-8
# vim /etc/locale.conf
LANG=en_US.UTF-8
# vim /etc/sysconfig/i18n
LANG=en_US.UTF-8
# vim /etc/environment
LANG=en_US.UTF-8
LC_ALL=en_US.UTF-8
