以下是解决中文乱码的
yum install fontconfig
mkdir -p /usr/share/fonts/chinese/
将C:\Windows\Fonts里的你需要的中文字体文件放到/usr/share/fonts/chinese/目录下
宋体文件为：simsun.ttc
楷体文件为：simkai.ttf
可以先创建个目录，把你需要的中文字体拷贝过去，然后再从那个目录上传到/usr/share/fonts/chinese/目录下
例如：
md E:\fonts\
copy C:\Windows\Fonts\simsun.ttc E:\fonts\
copy C:\Windows\Fonts\simkai.ttf E:\fonts\
可以用rz命令或filezilla客户端走sftp协议先上传到服务器 然后执行下面2句
chmod -R 755 /usr/share/fonts/chinese
fc-cache -fv
然后就可以用fc-list命令查看已经安装的字体了
然后reboot用mstsc远程即可
