Some questions about the use of CentOS 7 are summarized

Recently used Centos7 gnome and KDE, where GNOME desktop is not beautiful, and occupy the CPU and mem occupy a small footprint, but the machine load is very high, and finally cause the CPU temperature is high automatic shutdown, may be a driver problem, using KDE is a good solution to the problem;

The process for installing and personalizing the environment using KDE is as follows:

1, CentOS 7 KDE installation is selected in Chinese, but after installation is English, $LANG is zh-utf-8; After analysis may be no Chinese language pack;

Yum List | grep "Kde-*-chinese"

Kde-l10n-chinese.noarch

Install the package;

Yum-y Install KDE L10n-chinese.noarch

Log off or restart after installation;

2, whether it is GNOME or KDE support Firefox browser, but the individual always feel that Firefox parsing slow, high occupancy resources, so still keen on Google browser, so install Google browser (although Google Server launched in Celestial, and the Celestial shield, Lucky service is still there)

In addition to compiling the installation (the compilation installation is time-consuming and there are many uncertainties), the RPM installation

First Configure Yum

32-bit system, copy the following and save

[Google-i386]name=google-i386baseurl= enabled=1 gpgcheck=1 gpgkey=https://dl-ssl.google.com/linux/linux_signing_key.pub

64-bit system, copy the following and save

[Google-x86_64]name=google-x86_64baseurl= enabled=1 gpgcheck=1 gpgkey=https://dl-ssl.google.com/linux/linux_ Signing_key.pub

Install after configuration.

to open the terminal, Ann needs to install different versions of Chrome.
To install a stable version:yum install google-chrome-stable
To install the test version:yum install google-chrome-beta
To install an unstable version:yum install google-chrome-beta

但是此时会出现gpg密钥错误，不要着急；

yum --nogpgcheck localinstall /var/cache/yum/x86_64/7/google-x86_64/packages/google-chrome-stable-39.0.2171.99-1.x86_64.rpm





google 浏览器安装完成，可以使用，如果是在root环境下使用需要在浏览器命令后面加上 “-user-data-dir”OK&KO.





3、虚拟机安装

经过测试由于内核版本和C 文件问题，vmware在centos 7下安装后不能运行，查找也没有解决问题，好在我们有开原的virtualbox可以完美的支持virtualbox，而且可以yum安装；

首先设置环境

yum install kernel-devel kernel-headers gcc-*

gcc-* 是我自己顺便安装的编译环境！

最好再更新一下系统

yum update

Download Public key

wget http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc

Import Public key

RPM--import oracle_vbox.asc

Download Yum Warehouse file

wget Http://download.virtualbox.org/virtualbox/rpm/el/virtualbox.repo-O/etc/yum.repos.d/virtualbox.repo

Installing VirtualBox

< Span style= "Color:rgb (51,51,51); Font-family:arial;font-size:14px;line-height:26px;background-color:rgb ( 255,255,255); " >yum Install VirtualBox-4.3

< Span style= "Color:rgb (51,51,51); Font-family:arial;font-size:14px;line-height:26px;background-color:rgb ( 255,255,255); " >ok, waiting for the installation to complete, in fact, after downloading the installation package can be package installation package backup, download sometimes is very slow;

4. Input Method

Centos7 default use of IBUs input method, I think people often use Sogou input method, then the Linux platform should be more receptive to the small penguin Fcitx Input method

1. Set Epel source, Epel should be a common source of Yum for CentOS

# yum Install Epel-release

Configure the Yum configuration file. Repo

#yum-config-manager--add-repo=https://copr.fedoraproject.org/coprs/mosquito/myrepo/repo/epel-7/ Mosquito-myrepo-epel-7.repo

Various input methods for Ann

#yum install fcitx-googlepinyin fcitx-cloudpinyin # Google Pinyin Input method

# yum Install fcitx-sunpinyin sunpinyin-data fcitx-cloudpinyin # sunpinyin IME
