linux分布式安装hadoop1.2

配置环境

准备: 三台虚拟机

配置主节点:

1. 查看当前使用网卡


[root@localhost ~]# dmesg | grep -i eth
Bluetooth: BNEP (Ethernet Emulation) ver 1.3
eth0: no IPv6 routers present
dmesg是显示开机启动信息, grep -i是忽略大小写查找


2. 查看当前ip、网关

[root@localhost ~]# ifconfig
eth0      Link encap:Ethernet  HWaddr 00:0C:29:E0:C3:61  
          inet addr:192.168.182.138  Bcast:192.168.182.255  Mask:255.255.255.0
          inet6 addr: fe80::20c:29ff:fee0:c361/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:24092 errors:0 dropped:0 overruns:0 frame:0
          TX packets:12373 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:35176927 (33.5 MiB)  TX bytes:672502 (656.7 KiB)
          Interrupt:19 Base address:0x2024 

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:8 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:480 (480.0 b)  TX bytes:480 (480.0 b)
配置静态IP:
[root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth0"
#BOOTPROTO="dhcp"
BOOTPROTO="static"
HWADDR="00:0C:29:E0:C3:61"
#IPV6INIT="yes"
IPV6INIT="no"
NM_CONTROLLED="yes"
ONBOOT="yes"
TYPE="Ethernet"
UUID="7039ffae-3334-4445-b571-a805eecd4a77"
IPADDR=192.168.182.101
NETMASK=255.255.255.0
GATEWAY=192.168.182.255
修改主机名:



[root@localhost ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=master
[root@localhost ~]# hostname master
[root@localhost ~]# hostname
master

修改hosts文件:

[root@localhost ~]# vi /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.182.101 master
关闭防火墙(生产环境不能关闭, 需要添加允许列表)
[root@localhost ~]# service iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]
[root@localhost ~]# chkconfig iptables off
关闭 selinux
[root@localhost ~]# vi /etc/selinux/config



将SELINUX的值对应修改为: SELINUX=disabled

将两台从属节点按照上面的配置配好, ip分别设置为192.168.182.102和192.168.182.103, 主机名分别为slave1、slave2。
