1、最小化安装linux，配置好yum源
安装依赖包
yum -y install binutils compat-libcap1 gcc gcc-c++ glibc glibc.i686 glibc-devel glibc.i686 ksh libaio libaio.i686 libaio-devel libaio-devel.i686 libgcc libgcc.i686 libstdc++ libstdc++l7.i686 libstdc++-devel libstdc++-devel.i686 compat-libstdc++-33 compat-libstdc++-33.i686 libXi libXi.i686 libXtst libXtst.i686 make sysstat smartmontools net-tools
---其他包 解压，xmanager远程
yum -y install unzip install xorg-x11-server-utils xorg-x11-utils
---sysctl
