1. cetnos inital steps

设置中文输入法和中文界面
第一步：中文界面-通过GUI操作，在设置面板中regional and language选择中文
第二步：安装ibus-libpinyin，yum install ibus-libpinyin
第三步：启用ibus-libpinyin，首先启用ibus-setup，然后会有弹窗需要将下述加入~/.bashrc：
export GTK_IM_MODULE=ibus
export XMODIFIERS=@im=ibus
export QT_IM_MODULE=ibus
然后source ~/.bashrc，再到设置面板中regional and language选择输入源选择中文中的intelligent pinyin。就大工告成！
