centos7 桌面化配置

1、丰富常用的yum源及插件

CentOS-Base.repo(系统自带源)

epel源： yum install epel-release

elrepo源：rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

        rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm

nux-dextop源: 先下载  https://copr.fedoraproject.org/coprs/librehat/shadowsocks/  下载比较慢，多试几次之后就好了。

安装：rpm -ivh nux-dextop-release-0-1.el7.nux.noarch.rpm

2、.安装cairo-dock栏


Mac系统的dock栏是不是很惊艳，linux下也有类似应用( ^ω^)

此应用需要nux-desktop源支持，所以如果之前的yum源都配上了，那下面就很简单了，一句命令搞定：yum install cairo-dock

执行yum install cairo-dock 经常提示No package cariro-dock available  多试几次就好了，和网络有关系

到最后的时候报错

Transaction check error:
  file /usr/lib/systemd/system/blk-availability.service from install of device-mapper-7:1.02.107-5.el7.x86_64 conflicts with file from package lvm2-7:2.02.105-14.el7.x86_64
  file /usr/sbin/blkdeactivate from install of device-mapper-7:1.02.107-5.el7.x86_64 conflicts with file from package lvm2-7:2.02.105-14.el7.x86_64
  file /usr/share/man/man8/blkdeactivate.8.gz from install of device-mapper-7:1.02.107-5.el7.x86_64 conflicts with file from package lvm2-7:2.02.105-14.el7.x86_64
Error Summary
于是下载安装rpm -ivh lvm2-2.02.115-3.el7.src.rpm

结果提示：

新建立个组

#groupadd mockbuild
#useradd mockbuild -g mockbuild

还是报之前的错。

于是yum upgrade     之前做过一次系统更新，结果导致系统直接启动不起来。悲催的只好重装了系统。因此要注意upgrade和update的区别

注意 yum update 和 yum upgrade的区别

yum -y update
升级所有包，改变软件设置和系统设置,系统版本内核都升级
yum -y upgrade
升级所有包，不改变软件设置和系统设置，系统版本升级，内核不改变

upgrade 执行后有1641个包要更新，漫长的等待

.。。。。。。。。。

upgrade之前

[root@gxcc soft]# uname -r
3.10.0-123.el7.x86_64

upgrade 之后 重启，启动界面会多一个启动内核。

再次安装cairo-dock 就一切顺利了。

自此dock也出现了。
