ifconfig命令不能使用
1、直接输入:/sbin/ifconfig
2、临时修改环境变量:在shell中输入$export PATH = $PATH:/sbin然后再输入ifconfig命令即可,但是这只是临时更改了shell中的PATH,如果关闭shell,则修改消失,下次还需要重复如上操作。
3、永久修改PATH变量使之包含/sbin路径:打开/etc/profile文件,在其中输入export PATH=$PATH:/sbin,保存并重启X即可,这样一来,PATH路径永久修改成功,以后任何时候只需输入ifconfig命令即可
SSH远程连接
sudo apt-get install openssh-server openssh-client
sudo /etc/init.d/ssh restart
ip配置
方式一:动态ip
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
source /etc/network/interfaces.d/*
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto ens33
iface ens33 inet dhcp

Java环境(JDK)
a.复制jdk-8u65-linux-x64.tar.gz到 ~/Downloads
$>cp /mnt/hgfs/downloads/bigdata/jdk-8u65-linux-x64.tar.gz ~/Downloads
b.tar jdk-8u65-linux-x64.tar.gz
$>cd ~/Downloads
$>ta tar -xzvf jdk-8u65-linux-x64.tar.gz
c.移动到jdk1.8.0_65到/soft下
$>mv ~/Downloads/jdk1.8.0_65 /soft
$>ln -s /soft/jdk-xxx jdk //创建符号连接
d.配置环境变量
[/etc/environment]
JAVA_HOME=/soft/jdk
PATH="...:/soft/jdk/bin"
e.让环境变量生效
$>source /etc/environment
f.检验安装是否成功
$>java -version
集群搭建
