配置java

启动ftp

[root@master ~]# /etc/init.d/vsftpd restart

关闭 vsftpd：                                                     [失败]

为 vsftpd 启动 vsftpd：                                               [确定]

默认情况下 root不允许使用ftp

[root@master vsftpd]# pwd

/etc/vsftpd

[root@master vsftpd]# ls

ftpusers  user_list

将这两个文件中的root注释掉。

然后重启ftp

在两台机器上创建文件夹

[root@master ~]# mkdir installer

[root@master ~]#

上传jdk

E:\开发工具

jdk-7u79-linux-i586.rpm

到installer目录

Master机器

[root@master installer]# rpm -ivh jdk-7u79-linux-i586.rpm

添加hadoop用户

[root@master ~]# useradd hadoop

[root@master ~]# passwd hadoop

Changing password for user hadoop.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

[root@slave ~]# useradd hadoop

[root@slave ~]# passwd hadoop

Changing password for user hadoop.

New UNIX password:

BAD PASSWORD: it is based on a dictionary word

Retype new UNIX password:

passwd: all authentication tokens updated successfully.

并且在slave1和slave2使用hadoop用户创建installer目录

[root@master ~]# su - hadoop

[hadoop@master ~]$ mkdir installer

[root@slave ~]# su - hadoop

[hadoop@slave ~]$ mkdir installer

配置ssh等效性

一路回车键

[hadoop@master ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/hadoop/.ssh/id_rsa):

Created directory '/home/hadoop/.ssh'.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/hadoop/.ssh/id_rsa.

Your public key has been saved in /home/hadoop/.ssh/id_rsa.pub.

The key fingerprint is:

32:da:01:64:6a:48:4c:f0:58:4f:60:2e:ea:18:a0:5d hadoop@master

[hadoop@slave ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.

Enter file in which to save the key (/home/hadoop/.ssh/id_rsa):

Created directory '/home/hadoop/.ssh'.

Enter passphrase (empty for no passphrase):

Enter same passphrase again:

Your identification has been saved in /home/hadoop/.ssh/id_rsa.

Your public key has been saved in /home/hadoop/.ssh/id_rsa.pub.

The key fingerprint is:

80:49:e7:58:18:0b:9c:1f:ee:d8:96:5a:c5:50:a5:bb hadoop@slave

Master

[hadoop@master ~]$ cd .ssh/

[hadoop@master .ssh]$ ls

id_rsa  id_rsa.pub

[hadoop@master .ssh]$ cat id_rsa.pub > authorized_keys

[hadoop@master .ssh]$ scp authorized_keys slave:~/.ssh/

The authenticity of host 'slave (192.168.3.101)' can't be established.

RSA key fingerprint is de:5a:2e:67:62:a4:27:2c:d7:de:85:eb:c7:6c:93:c8.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added 'slave,192.168.3.101' (RSA) to the list of known hosts.

hadoop@slave's password:

authorized_keys

Slave

[hadoop@slave ~]$ cd .ssh/

[hadoop@slave .ssh]$ ls

authorized_keys  id_rsa  id_rsa.pub

[hadoop@slave .ssh]$ cat id_rsa.pub >> authorized_keys

[hadoop@slave .ssh]$ scp authorized_keys master:~/.ssh/

The authenticity of host 'master (192.168.3.100)' can't be established.

RSA key fingerprint is de:5a:2e:67:62:a4:27:2c:d7:de:85:eb:c7:6c:93:c8.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added 'master,192.168.3.100' (RSA) to the list of known hosts.

hadoop@master's password:

authorized_keys

最后

[hadoop@master .ssh]$ chmod 600 authorized_keys

[hadoop@slave .ssh]$ chmod 600 authorized_keys

到这里配置完毕，可以直接使用

[hadoop@master ~]$ ssh slave

[hadoop@slave ~]$ ssh master

配置hadoop

解压缩

[hadoop@master installer]$ tar -zxvf hadoop-2.6.0.tar.gz

[hadoop@master installer]$ mv hadoop-2.6.0 hadoop2

[hadoop@master installer]$ ls

hadoop2  hadoop-2.6.0.tar.gz

配置环境变量

[hadoop@master ~]$ vim .bashrc

# .bashrc

# Source global definitions

if [ -f /etc/bashrc ]; then

. /etc/bashrc

fi

# User specific aliases and functions

export JAVA_HOME=/usr/java/jdk1.7.0_79

export HADOOP_HOME=/home/hadoop/installer/hadoop2

export HADOOP_COMMON_LIB_NATIVE_DIR=${HADOOP_HOME}/lib/native

export HADOOP_OPTS="-Djava.library.path=$HADOOP_HOME/lib"

export CLASSPATH=$CLASSPATH:$HADOOP_HOME/lib:$JAVA_HOME/lib

export PATH=$PATH:$JAVA_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin

让bashrc生效

[hadoop@master ~]$ . .bashrc

[hadoop@master ~]$ scp .bashrc slave:~

.bashrc                                                                                            100%  341     0.3KB/s   00:00

配置hadoop文件

标红错误说 物理内存乘以2.1 得到210M，因为一开始我们设置了物理内存是100M

调整方法要么把2.1调整大，要么调整大物理内存

修改之前最好先停掉yarn
