hadoop的部署以及应用

1.基础环境

[hadoop@master ~]$ cat  /etc/redhat-release CentOS Linux release 7.2.1511 (Core) [hadoop@master ~]$ [hadoop@master ~]$ getenforce Disabled[hadoop@master ~]$ systemctl  status  firewalld ● firewalld.service - firewalld - dynamic firewall daemon   Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled)   Active: inactive (dead)[hadoop@master ~]$

2.IP以及对应节点

[hadoop@master ~]# cat  /etc/hosts192.168.56.100  Master192.168.56.101  slave1192.168.56.102  slave2192.168.56.103  slave3[hadoop@master ~]#

3.增加hadoop用户，所有节点

useradd  hadoopecho hadoop|passwd  --stdin  hadoop

4.jdk

[hadoop@slave1 application]# lltotal 4lrwxrwxrwx 1 root root   24 Jul 10 01:35 jdk -> /application/jdk1.8.0_60drwxr-xr-x 8 root root 4096 Aug  5  2015 jdk1.8.0_60[hadoop@slave1 application]# pwd/application[hadoop@slave1 application]# [hadoop@master ~]# java  -version java version "1.8.0_60"Java(TM) SE Runtime Environment (build 1.8.0_60-b27)Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)[hadoop@master ~]#

5.master(192.168.56.100)上的hadoop用户可以ssh所有slave节点的hadoop用户下

6.设置hadoop安装路径 以及环境变量（所有节点）

su  -  hadooptar xf  hadoop-2.7.0tar.gz/home/hadoop/hadoop-2.7.0vi /etc/profile  添加hadoop环境变量export HADOOP_HOME=/home/hadoop/hadoop-2.7.0export PATH=$PATH:$HADOOP_HOME/binsource /etc/profile

7.修改hadoop的环境的Java环境变量

/home/hadoop/hadoop-2.7.0/etc/hadoopvi hadoop-env.sh 添加###JAVA_HOMEexport JAVA_HOME=/application/jdk/

8.修改hadoop的配置文件

cd  /home/hadoop/hadoop-2.7.0/etc/hadoop1.##############################[hadoop@master hadoop]$ cat core-site.xml fs.default.name  hdfs://master:9000  hadoop.tmp.dir /home/hadoop/tmp[hadoop@master hadoop]$ 2.###################################(默认不存在 拷贝个模板即可)[hadoop@master hadoop]$ cat mapred-site.xml  mapred.job.tracker  master:9001  mapred.local.dir /home/hadoop/tmp[hadoop@master hadoop]$ 3.#########################################[hadoop@master hadoop]$ cat  hdfs-site.xmldfs.name.dir/home/hadoop/name1,/home/hadoop/name2,/home/hadoop/name3   dfs.data.dir/home/hadoop/data1,/home/hadoop/data2,/home/hadoop/data3   dfs.replication  3[hadoop@master hadoop]$ [hadoop@master hadoop]$ cat masters master[hadoop@master hadoop]$ cat slaves slave1slave2slave3[hadoop@master hadoop]$

9.分发到slave节点

scp   -r  /home/hadoop/hadoop-2.7.0  slave1:/home/hadoop/scp   -r  /home/hadoop/hadoop-2.7.0  slave2:/home/hadoop/scp   -r  /home/hadoop/hadoop-2.7.0  slave3:/home/hadoop/

10.master 节点测试

/home/hadoop/name1 /home/hadoop/name2  /home/hadoop/name3  这三个目录不要创建，如果创建会提示重新reloadcd  /home/hadoop/hadoop-2.7.0[hadoop@master hadoop-2.7.0]$ ./bin/hadoop namenode -formatDEPRECATED: Use of this script to execute hdfs command is deprecated.Instead use the hdfs command for it.17/07/10 02:57:34 INFO namenode.NameNode: STARTUP_MSG:
