更新包

sudo yum -y update

vagrant centos 默认语言好像是德语，看不懂，需要更换为 en_US

[vagrant@localhost ~]$ locale
LANG=de_DE.UTF-8
LC_CTYPE="de_DE.UTF-8"
LC_NUMERIC="de_DE.UTF-8"
LC_TIME="de_DE.UTF-8"
LC_COLLATE="de_DE.UTF-8"
LC_MONETARY="de_DE.UTF-8"
LC_MESSAGES="de_DE.UTF-8"
LC_PAPER="de_DE.UTF-8"
LC_NAME="de_DE.UTF-8"
LC_ADDRESS="de_DE.UTF-8"
LC_TELEPHONE="de_DE.UTF-8"
LC_MEASUREMENT="de_DE.UTF-8"
LC_IDENTIFICATION="de_DE.UTF-8"
LC_ALL=

sudo vim /etc/sysconfig/i18n

将 LANG="de_DE.UTF-8" 替换为 LANG="en_US.UTF-8" 然后按 Esc 键，输入:wq 保存并退出vim编辑器

1. centos 的中文切换为英文！ 修改了 语言之后，重启之后，更换到了
2. CentOS中/英文环境切换教程（CentOS6.8） 学习到查看本地的语言

[vagrant@localhost ~]$ sudo yum upgrade

参考 问题：用yum安装docker，更新yum存储时，报以下错误，导致yum坏了

因为我的是 centos6,而参考的是 centos7,需要进入镜像站中，找相同报名，不同版本的文件

sudo rpm -qa|grep yum|sudo xargs rpm -e --nodeps  
rpm -qa |grep yum
wget http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.noarch.rpm
wget http://centos.ustc.edu.cn/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-41.el6.noarch.rpm
sudo rpm -ivh yum-*
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
sudo yum makecache

最终的效果

[vagrant@localhost ~]$ sudo rpm -ivh yum-*

在 180803.md 遇到一样的问题，使用 sudo yum install epel-release 即可解决
