CentOS配置

增加用户权限:

  1. 切换到root

>su root

  1. 编辑 sudo nano /etc/sudoers

neworigin        ALL=(ALL)      NOPASSWD: ALL

 

静态ip:

 

  1. 修改网卡

sudo nano /etc/udev/rules.d/70-persistent-net.rules

 

 

 

  1. 修改ip

例如:

sudo nano /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE="eth1"
         BOOTPROTO="static"
         #BROADCAST=192.168.1.255
         HWADDR="00:0c:29:74:31:5d"
         IPV6INIT="no"
         NM_CONTROLLED="yes"
         ONBOOT="yes"
         TYPE="Ethernet"
         UUID="65c0f600-27be-45e0-b567-1bff8ceff71d"

IPADDR=192.168.1.191
         GATEWAY=192.168.1.1
         NETMASK=255.255.255.0
         DNS1=114.114.114.114
         DNS2=8.8.8.8

 

 

  1. 重启
                       [root@bogon neworigin]# sudo /etc/init.d/network restart
  2. 测试
                      ping www.baidu.com

 

修改主机名:

> sudo nano /etc/hostname

 

 

[hosts]

>sudo nano /etc/hosts

 

 

 

关闭防火墙:

关闭命令:  service iptables stop 
        永久关闭防火墙:chkconfig iptables off

两个命令同时运行,运行完成后查看防火墙关闭状态 
        service iptables status

 

 

修改主机名:sudo nano /etc/sysconf/network

 

 

sudo reboot

重启之后:变成

 

 

安装jdk

 

 

安装hadoop

cp /mnt/hgfs/xiazai/cdh/hadoop-2.5.0-cdh5.3.6.tar.gz /tools

tar -xzvf hadoop-2.5.0-cdh5.3.6.tar.gz

 

【安装解压以下文件,然后配置环境】

 

 

 

 

配置环境:

#java

export JAVA_HOME=/tools/jdk1.7.0_67

export PATH=$PATH:$JAVA_HOME/bin

 

#hadoop

export HADOOP_HOME=/tools/hadoop-2.5.0-cdh5.3.6

export PATH=$PATH:$HADOOP_HOME/bin

export PATH=$PATH:$HADOOP_HOME/sbin

 

#hbase

export HBASE_HOME=/tools/hbase-0.98.6-cdh5.3.6

export PATH=$PATH:$HBASE_HOME/bin

 

#zookeeper

export ZOOKEEPER_HOME=/tools/zookeeper-3.4.5-cdh5.3.6

export PATH=$PATH:$ZOOKEEPER_HOME/bin

 

#hive

export HIVE_HOME=/tools/hive-0.13.1-cdh5.3.6

export PATH=$PATH:$HIVE_HOME/bin

 

第二台

 

 

centos配置免密:

su root

修改sshd的配置文件:

nano /etc/ssh/sshd_config

找到以下内容,并去掉注释符“#”   

RSAAuthentication yes   

PubkeyAuthentication yes   

AuthorizedKeysFile .ssh/authorized_keys

重启sshd服务:

/etc/init.d/sshd restart

切回需要免密的用户neworigin

生成公钥和私钥

ssh-keygen -t rsa

会在~/.ssh下面生成:id_rsa(私钥),id_rsa_pub(公钥)

 

把公钥导入到认证文件:

cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

chmod 700 ~/.ssh

chmod 600 ~/.ssh/authorized_keys

 

测试:ssh localhost

ssh-copy-id slaver1(拷贝到需要免密登录的主机)

配置多台相互之间免密就是重复上面的步骤,最后:ssh-copy-id 主机n
