linux分布式安装hadoop1.2

yne7 10年前

三台机器，centos6.5， master、slave1、slaver2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。
