系统字符编码
CentOS-6
1.查看编码信息
[root@localhost ~]# echo $LANG
en_US.UTF-8
[root@localhost ~]# locale
LANG=en_US.UTF-8
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=
查看当前系统支持的字符集：
[root@localhost ~]# locale -a
2.临时修改
[root@localhost ~]# LANG=en_US.UTF-8 # 基本用不到
3.永久修改
方法一：
[root@localhost ~]# vim /etc/profile
文件最后添加：export LANG='en_US.UTC'
[root@localhost ~]# source /etc/profile
[root@localhost ~]# echo $LANG
en_US.UTC
方法二：
[root@localhost ~]# vim /etc/sysconfig/i18n
[root@localhost ~]# cat /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"
[root@localhost ~]# source /etc/sysconfig/i18n
[root@localhost ~]# echo $LANG
en_US.UTF-8
