修改字符编码解决linux终端中文乱码

1、查看当前的字符编码
[root@bogon clientUpdate]# locale
LANG=zh_CN.utf8
LC_CTYPE="zh_CN.utf8"
LC_NUMERIC="zh_CN.utf8"
LC_TIME="zh_CN.utf8"
LC_COLLATE="zh_CN.utf8"
LC_MONETARY="zh_CN.utf8"
LC_MESSAGES="zh_CN.utf8"
LC_PAPER="zh_CN.utf8"
LC_NAME="zh_CN.utf8"
LC_ADDRESS="zh_CN.utf8"
LC_TELEPHONE="zh_CN.utf8"
LC_MEASUREMENT="zh_CN.utf8"
LC_IDENTIFICATION="zh_CN.utf8"
LC_ALL=


2、查找需要修改成的字符编码
[root@bogon clientUpdate]# locale -a|grep gbk
zh_CN.gbk
zh_SG.gbk

3、临时修改当前环境变量的字符编码，立刻生效
[root@bogon clientUpdate]# export LANG=zh_CN.gbk

4、查看是否生效
[root@bogon clientUpdate]# locale 
LANG=zh_CN.gbk
LC_CTYPE="zh_CN.gbk"
LC_NUMERIC="zh_CN.gbk"
LC_TIME="zh_CN.gbk"
LC_COLLATE="zh_CN.gbk"
LC_MONETARY="zh_CN.gbk"
LC_MESSAGES="zh_CN.gbk"
LC_PAPER="zh_CN.gbk"
LC_NAME="zh_CN.gbk"
LC_ADDRESS="zh_CN.gbk"
LC_TELEPHONE="zh_CN.gbk"
LC_MEASUREMENT="zh_CN.gbk"
LC_IDENTIFICATION="zh_CN.gbk"
LC_ALL=


5、修改配置文件，保证重启后仍然生效
[root@bogon clientUpdate]# cat /etc/sysconfig/i18n 
LANG=zh_CN.GBK
[root@bogon clientUpdate]# 
[root@bogon clientUpdate]# export LC_ALL=zh_CN.gbk
[root@bogon clientUpdate]# locale
