In the CentOS English environment, you can use the ibus Input Method in the English environment. Generally, you cannot use Chinese in the English environment. This is because we have not set the Chinese configuration in the English environment. In the English environment, configure the Chinese Input Method ibus so that we can enter Chinese. First, install ibus (which has been installed by default after centos6) # yum install ibus www.2cto.com. Second, copy the installation package to an English environment # cp/usr/share/locale/zh_CN/LC_MESSAGES/ibus */usr/share/locale/en_US/LC_MESSAGES set ibus to an English environment startup item # vi/etc/X11/xinit/xinitrc. d/50-xinput.sh find _ im_1_age_list = "as bn gu hi ja kn ko ml mr ne or pa si ta te th ur vi zh" in the list and add "en" to the system --> in the input method settings, add a Chinese input method. Save and restart.
