hadoop学习笔记-ubuntu使用：IP查看、xshell连接和ftp环境搭建

 

第一部分 IP查看

1.下载net-tools，ifconfig命令工具包
   sudo apt-get install net-tools
2.输入命令：ifconfig ，inet 之后为IP信息
hadoop@ubuntu:~$ ifconfig
ens33: flags=4163  mtu 1500
        inet 192.168.36.128  netmask 255.255.255.0  broadcast 192.168.36.255
        inet6 fe80::e22f:9703:8997:8011  prefixlen 64  scopeid 0x20
        ether 00:0c:29:dc:b9:62  txqueuelen 1000  (Ethernet)
        RX packets 21404  bytes 26940446 (26.9 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 8361  bytes 793052 (793.0 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

lo: flags=73  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10
        loop  txqueuelen 1000  (Local Loopback)
        RX packets 425  bytes 35039 (35.0 KB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 425  bytes 35039 (35.0 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

第二部分 xshell连接ubuntu

步骤：a.安装SSH，b.安装xshell，c.xshell连接ubuntu

1.安装SSH

xshell远程连接ubuntu是通过ssh协议,需要给ubuntu安装ssh服务:

ubuntu执行命令：sudo apt-get install openssh-server

hadoop@ubuntu:~$ sudo apt-get install openssh-server
[sudo] password for hadoop: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following additional packages will be installed:
  ncurses-term openssh-client openssh-sftp-server ssh-import-id
Suggested packages:
  keychain libpam-ssh monkeysphere ssh-askpass molly-guard rssh
The following NEW packages will be installed:
  ncurses-term openssh-server openssh-sftp-server ssh-import-id
The following packages will be upgraded:
  openssh-client
 

SSH服务重启命令：sudo service ssh restart

PS：ssh远程连接时通过网络连接，如果连接不上可检查网络，ping下IP是否通，重启服务；

 

2.安装xshell

a.windows宿主机下载xshell安装包，安装xshell程序；

xshell安装包百度云地址：https://pan.baidu.com/s/1eHTp6uLaTapNELlF2_g_rg

提取码：52dz

b.安装成功后，启动xshell：新建》输入IP信息》点击确定》点击连接，选择协议：ssh

输入用户账号和密码
