## 一些必须要装的软件
yum -y update
yum -y install tmux && ln -s /usr/bin/true /etc/sysconfig/bash-prompt-screen #软链接是为了解决tmux窗口名称被莫名重置的问题

yum -y install krb5-devel #安装`mongoose`报错，`gssapi.h：No such file or directory`

#修改vi指向vim
mv /usr/bin/vi /usr/bin/vi_bak
ln -s /usr/bin/vim /usr/bin/vi

cd /root
useradd centos
echo 'ddxd2015' | passwd --stdin centos

# 为centos增加sudo权限
