note：

1）最小化安装，默认网卡没有开机自动启动，可以编辑网卡文件(默认为ifcfg-eth0)，将ONBOOT修改为yes

[[email protected] ~]# vim \/etc\/sysconfig\/network-scripts\/ifcfg-eth0

ONBOOT=yes

2）安装系统基本依赖包，用于编译安装软件

[[email protected] ~]# yum install net-tools vim wget make gcc g++ gc++ -y

3）关闭防火墙和SELinux，防止系统干扰导致部署不成功

[[email protected] ~]# setenforce 0

[[email protected] ~]# iptables -F

[[email protected] ~]# iptables -X

安装JDK

[[email protected] app]# ll

-rw-------. 1 root root 181352138 Sep 6 22:54 jdk-8u101-linux-x64.tar.gz

[[email protected] app]# ln -s jdk1.8.0_101 jdk
